Cord-cutting: Yet More Perspectives

On the heels of the Consumer Electronics Association’s recent study of cord-cutters comes yet more research on the phenomenon. But this one should be taken more seriously than the CEA’s efforts because it focuses on a specific demographic – Generation Y, or those born in or after 1979.

 

‘Gen Ys’ are a critical group to watch. Their viewing habits and decisions are of tremendous interest to advertisers and marketers, as they currently occupy the lion’s share of the coveted 18-35 demographic.

 

Gen Ys literally grew up with computers and embrace new electronic gadgets more quickly than Gen Xers and us ‘old fogies’ in the Baby Boomer group. They are ‘connected’ with smart phones, laptops, and tablets, and are just as likely to search out video content on the Internet as watch it through cable or satellite TV services.

 

The study, conducted by research firm Ideas and Solutions! of Los Angeles, states that pay TV service providers are at risk of losing this group due to increasing price sensitivity to subscription television. According to a story in MediaPost, 69% of so-called ‘on the fence’ Gen Y cable customers are classified as ‘at risk’ for dropping service because it’s just too expensive.

 

This group spends nearly half of their TV viewing time watching Netflix and Hulu. Of the survey group that still favors pay TV, Netflix and Hulu viewing dropped to about 25%.

 

The survey results should surprise no one who knows Gen Y well. I have two ‘connected’ Gen Ys in my family (ages 25 and 20), and they’re always looking for ways to cut down on expenses. Some Gen Ys have enormous college loans and low-paying jobs (or are unemployed, or temping), so pay TV is an expensive luxury when compared to rent, groceries, and gas for the car (if they own one!).

 

This group is also more interested in broadband access than pay TV channel packages, and that’s already having an impact on the established subscription TV business.  A story in today’s Wall Street Journal quotes Time Warner CEO Glenn Britt as saying that broadband is rapidly becoming the company’s ‘anchor product,’ and that “…people are telling us that if they were down to their last dollar, they’d drop broadband last.”

 

Britt went on to point out that TW’s broadband customer count is closing in on its residential video customer count (9.5M vs. 12.3M in Q1 ’11). Also, TW has another 2M broadband-only customers, many of which have dropped cable for satellite services. You can be sure Gen Ys are well represented in the totals for broadband service.

 

The result is that TW may shift to more of a ‘single play’ marketing effort, pushing broadband at the expense of subscription TV and voice over IP (VoIP). The latter service is a harder sell to Gen Ys, as they rely on their mobile phones and often have no wireline telephones in their apartments and homes.

 

In my experience, Gen Ys who are informed about or become aware of free, over-the-air digital TV are quite happy to watch it as a substitute for pay TV, mixing it with YouTube, Netflix, and Hulu. The question is; how many Gen Ys even know they can get free digital TV?

 

Maybe it’s time for a new outreach campaign by NAB, broadcast networks, and TV station ownership groups!

Reading Between The Lines

In a report released yesterday, the Consumer Electronics Association states that 10% of American households are either ‘very likely’ or ‘likely’ to cancel pay TV services this year, while an additional 14% are either ‘somewhat likely’ or ‘somewhat unlikely’ to cut the cord. 76% of those surveyed were in the ‘unlikely’ or ‘very unlikely’ group.

While those numbers should give some pay TV operators a little cause for concern – maybe as an incentive to offer simpler, basic channel packages at lower costs – the CEA report then veered off in another direction.

The report, which you can read here, states that only 8% of all U.S. households rely exclusively on over-the-air (OTA) TV reception, a number that was immediately disputed by the national Association of Broadcasters, according to a story in Multichannel News.

The MCN story quoted CEA president and CEO Gary Shapiro as saying, “Contrary to the National Association of Broadcasters’ assertions, antenna sales are falling and cord-cutters are not shifting to over-the-air television but rather to the Internet. The only cord being cut these days is the one to the antenna.”

NAB’s spokesman Dennis Wharton was quick to respond. “CEA has zero credibility when it comes to calculating over-the-air TV viewership. Knowledge Networks has stated that over-the-air exclusive homes are more than 14% and rising. We trust an unbiased research firm over a survey paid for by CEA,” he replied.

Both my own experience and national news stories about cord-cutting have clearly shown that free, over-the-air TV is a key component of the cord-cutting experience. Why? Because it’s doggone difficult to watch sports and prime time TV shows in HDTV over a typical Internet connection, that’s why! And of course, OTA TV is free to viewers. So it is often combined with broadband access as part of the kiss-off to Comcast or Time Warner.

As it turns out, CEA has an obvious bias here. (Wow – this has been a bad week for objective research!) In a press release that came out earlier today, CEA announced that its Innovation Movement and Small Business Council would bring a ‘small business message’ to Capitol Hill.

The message? That small businesses “…run a gauntlet of new laws, new regulations and new costs that can put them out of business. Instead of imposing additional burdens, policymakers should be creating small businesses to invest, expand and create additional jobs.”

So where’s the bias? In the fifth paragraph of the press release, CEA states:

“Online, CEA’s Innovation Movement will be hosting a Virtual Lobby Day for its 114,000-plus members to encourage them to act on one key issue affecting small businesses: incentive spectrum auctions. CEA Innovation Movement members will be called to ask their congressional representatives to authorize the FCC to move forward with “incentive auctions,” which would provide broadcasters the ability to repurpose their frequencies through a spectrum auction in exchange for proceeds from auction revenues. Broadcasters could participate on a voluntary basis and purchasers could redeploy the spectrum for wireless broadband that could generate $33 billion for the U.S. Treasury and would allow endless opportunities for innovation in small business. “

A-HA! Apparently the primary motivation of this Innovation Movement is to pressure congress into selling off more broadcast TV spectrum. How, exactly, does that benefit a so-called ‘small business’ like mine? Seems to me such auctions would be far more useful Verizon and AT&T more than anyone else, and they’re as far removed from ‘small businesses’ as you can get.

According to Shapiro, “Using huge swaths of wireless spectrum to deliver TV to homes no longer makes economic sense. Congress should pass legislation to allow for incentive auctions so free market dynamics can find the best purposes for underused broadcast spectrum, such as wireless broadband.”

OK, connect the dots with me: (1) CEA’s members want more spectrum for broadband and other WiFi gadgets. (2) They think terrestrial broadcasters are vulnerable now. (3) So, CEA commissions a study that shows only while a small number of people are dropping or planning to drop pay TV service, these cord-cutters are NOT moving to over-the-air reception. No, they are instead turning to Internet-delivered video services. (4) Therefore, the country needs more bandwidth for broadband delivery of (among other things) video content, and less bandwidth for broadcast TV programs.

And I thought the recent Digital Entertainment Group survey of 3D TV trends was self-serving!  While I have no issue with the small number of cord-cutters the CEA identified, I simply cannot believe these ‘cutters’ would turn away from free HDTV programming for their new LCD and plasma TVs.

The CEA’s bias is clear now. In the last decade, they fought the digital TV tuner mandate, calling it an undue burden on TV manufacturers. Once the DTV transition got rolling, however, CEA did a flip-flop and showered praise on the FCC’s decision to move to a digital TV future, bringing free HDTV to millions of American homes.

Now, CEA has flipped again and says that free OTA TV is a dinosaur, and should be consigned to the dustbin of history in favor of wireless broadband in the UHF television band (a concept that is still on shaky ground technically).

I’m surprised the folks at CEA haven’t gotten whiplash from constantly reversing their positions. But it’s pretty clear now who’s really behind the curtains, calling the shots for CEA and also putting pressure on the FCC these days.

The question is; how many Americans still care that they can watch free HDTV anymore?

I’ll bet it’s a lot more than 8% of all U.S. households…

NAB 2011: It’s All About Streaming, Displays, and Connectivity

With each passing year, NAB looks less and less like a broadcaster’s show and more like a cross between CES and InfoComm. It’s a three-ring circus of product demos, panel discussions, conferences, and media events that all points to the future of ‘broadcasting’ as being very different than what it was at the end of the 20th century.

 

Officially, slightly less than 90,000 folks showed up to walk the floors of the Las Vegas Convention Center, and it was elbow-to-elbow in some exhibits. But there was another trend of smaller booths for the ‘big name’ exhibitors like Panasonic and JVC.

 

That reflects the reality of selling products that have mostly three and four zeros in their price tags. At my first NAB in 1995, it wasn’t unusual to see $50,000 cameras and $80,000 recorders. Now, you can buy some pretty impressive production cameras for about $5,000.

 

Streaming and over-the-top video was big this year. Ironically, NAB featured an enormous streaming media pavilion back in 1999, but it vanished the next year. The reason? A lack of broadband services across the country that could support streaming at reasonable bit rates.

 

Obviously, that’s all changed now, what with Netflix at 21 million subscribers and climbing, and MSOs deploying multi-platform delivery of video and audio to a plethora of handheld devices. Concurrently, the broadcast world is trying to roll out a new mobile handheld (MH) digital TV service to stand-along portable receivers and specially-equipped phones.

 

And behind all of this, the FCC continues to make noise that it wants to grab an additional 100 – 120 MHz of UHF TV spectrum to be repurposed for wireless broadband, a service you’ll have to pay for. Attendees had mixed thoughts on whether the Commission will actually be able to pull this off – there is some opposition in Congress – but there appeared to be a high level of opposition to the plan, considering there is plenty of other spectrum available for repurposing, much of it already used exclusively for government and military purposes.

 

Like last year, there were lots of 3D demos, but the buzz wasn’t really there. 3D still has a ways to go with its roll-out and it simply can’t compete with the interest in content delivery to smart phones, tablets, and other media players. Still, there were some cool 3D products to be found here and there.

 

Here are some of the highlights from the show.

Is that an MH receiver in your pocket, or are you just glad to watch DTV?

ATSC MH Pavilion – several companies exhibited a range of receivers for the MH services being transmitted during the show from Las Vegas TV stations and low-power rigs in the convention center. LG and RCA both showed some snazzy portable MH receivers, with LG’s exhibit putting the spotlight on autostereo 3D MH (as seen at CES) and a service call ‘Tweet TV’ which would allow viewers to comment on shows they’re watching and have those tweets appear on their MH receiver.

 

Another demo had CBS affiliate KLAS-DT transmitting electronic coupons for local retailers and restaurants during the show. These showed up on a prototype full-touch CDMA smart phone with a 3.2” HVGA screen.

 

In a nearby booth, RCA unveiled a lineup of hybrid portable DTV receivers. There are two 3.5” models (DMT335R, $119, and DMT336R, $159), a 7” version (DMT270R, $179), and a pocket car tuner/receiver that connects to an existing car entertainment center. It will sell for $129.

Believe it or not, this was a commercial for Coca-Cola.

Motorola had two intriguing demonstrations. The first showed full-bandwidth 3D content distribution, using the full 38.8 Mb/s bandwidth of a 256 QAM channel to transport frame-packed 1080p video with full 1920×1080 left eye and right eye images, encoded in the MPEG4 H.264 format and sequenced through active shutter glasses.

 

Nearby, an HD video stream was encoded for four different displays, with all four signals carried simultaneously in the same bit stream. First up was a 1080p/60 broadcast; next to that a 720p/60 version, followed by a standard definition version (480i) and a version sized for a laptop computer or tablet. Both MPEG2 and MPEG4 codecs were used.

 

Red Rover attracted quite a crowd with their 28″ 4K (3840×2160) 3D video monitor which uses two 4K LCD panels arranged at 90-degree angles to each other (one on top, facing down). A half-mirror with linear polarization is used to combine the left and right eye images for passive viewing. Both LCD panels are Samsung vertically-aligned models, and the whole works will sell for (ready for this?) $120,000.

Only $120K? That's a steal!

Volfoni showed dual-purpose 3D glasses at NAB. When powered on, they function as active shutter eyewear. Powered off, they are usable as passive 3D glasses. The whole shebang is controlled by an external power pack the size of an iPod nano that clips to your pocket or shirt, and this ‘pod’ can ‘learn’ any IR code from active shutter TVs.

 

The pod controller can step through several neutral density filters and there are several levels of color correction possible from the remote power pack. (Electronic sunglasses – imagine that!) The glasses use 2.4 GHz RF signaling technology to synchronize with any active shutter monitor or TV. And despite all of the bells and whistles, they weigh just over an ounce.

 

Sony’s 17″ and 25″ BVM-series OLED monitors that were first shown at the 2011 HPA Technology Retreat now have siblings. The PVM-E250 Trimaster OLED display is structurally the same as its more-costly BVM cousin, but has fewer adjustments and operating features. And it’s going to sell for quite a discount over the BVM version – just $6,100. There’s also a 17-inch version which wasn’t operating at the show, and it is expected to retail for $4,100.

 

Up at the front of the Central Hall, Panasonic was showing the TH-42BT300U, their first plasma reference-grade monitor. It’s not all that different from the exiting 20-series industrial plasma monitors in appearance, but there’s a big difference in operating features. Black levels have dropped and low-level noise has been minimized with a half-luminance PWM step. This results in more shades of gray and a smoother transition out of black.

 

In addition, the TH-42BT300U supports 3D playback for side-by-side and top + bottom color and exposure correction. Panasonic has also added automatic ’snap-to’ color space menu options, along with a user-definable color gamut option. When calibrated, it was an eye-catcher. There’s a 50-inch version also in the works, and both monitors will go on sale this fall.

Sony knows OLEDs. Make. Believe. (Nah, it was real...)

Panasonic's TH-42BT300U (left) maps color accurately to the BT.709 color space, unlike its sibling the TH-42PF20U (right).

Hyundai unveiled the B240X, a new 24″ passive stereo LCD monitor. It sports a 1920×1200 display with circularly-polarized film-patterned retarders and supports 3D side-by-side and top + bottom viewing formats. The pixel pitch is about .27 mm and brightness is rated at 300 nits. Hyundai also created an eye-catching 138″ (diagonal) 3×3 3D video wall for NAB, using its flagship S465D 46″ LCD monitor.

 

Sisivel has come up with a unique way to deliver higher-resolution 3D TV in the frame-compatible format. Instead of throwing away half the horizontal resolution for 1080i side-by-side 3D transmissions, Sisivel breaks the left eye and right eye images into two 1280×720 frames. The left eye frame is carried intact in a 1920×1080 transmission, while the right eye is broken up into three pieces – the top 50% of the frame, and two half-frames that make up the bottom.

 

All of this gets packed in a rather unusual manner (see photo), but some simple video processing and tiling software re-assembles the right eye fragments into one image after decoding. Then, it’s a simple matter to sequence the lefty eye, right eye images as is normally done. The advantage of this format is that it has higher resolution than ESPN’s top+bottom 3D standard (two 1280×360 frames).

So THAT's how you pack two 1280x720 3D frames into a 1920x1080 broadcast. Clever, eh?

 

JVC announced two LCD production monitors at NAB. The DT-V24G11Z is a 24-inch broadcast and production LCD monitor that uses 10-bit processing and has a native resolution of 920×1200 pixels. The extra resolution provides area above and below a 1080p image for metering, embedded captions, and signal status. The incoming signal can also be enlarged slightly to fill the entire screen.

 

The DT-3D24G1Z is a 24-inch passive 3D monitor with circular polarization patterned films. It has 1920×1080 pixel resolution, 3G HD-SDI and dual-link inputs, a built-in dual waveform monitor and vectorscope, left eye and right eye measurement markers, and side-by-side split-screen display for post production work including gamma, exposure, and color/white balance correction.

 

Nearby, crowds gathered to see two new 4K cameras that use a custom LSI for high bitrate HD signal processing. The demo used a Sharp 4K LCD monitor, and the cameras were running at 3840×2160 resolution. They have no model numbers or price tags yet.

 

Ikegami’s field emission display (FED) monitor that attracted so much attention a few NABs ago, but was written off when Sony pulled out its investment from the manufacturer, is now back. Its image quality compared favorably with Sony’s E-series BVM OLED monitors, and the images displayed with a wide H&V viewing angle and plenty of contrast pop. It was being used to show images from a Vinten robotic camera mount at NAB, and no pricing has been announced.

Forget the Canon SED, Ikegami's got an FED! (A 'what?')

Dolby showed their PRM-4200 42-inch HDR LCD reference monitor at NAB. While this product is not new, there was a substantial price cut announced at the show to $39,000.  Initial comments from the post production community have indicated the price is too high for today’s economic environment. As a result, Dolby has apparently sold a few to video equipment rental houses for location and studio production work.

 

Digital SLRs are being used to shoot TV productions such as “House” and independent films, and they could use a couple of good monitors with hot shoe mounts. Nebtek had a 5.6” model at the show, as did TV Logic. Both models sport 1280×800 (WXGA) resolution, compatibility with HD-SDI and HDMI inputs, and have on-screen display of waveform/vectorscope details, focus assist, and chroma/luma signal warnings. Embedded audio from the cameras’ HDMI output can be displayed on screen, and there are several scan and pixel mapping modes.

 

One of the more significant announcements at the show – at least, at first reading – was Verizon’s Digital Media Services. The idea is to serve as an electronic warehouse for everyone from content producers to digital media retailers – in effect, an Amazon e-commerce model, except that Verizon wouldn’t sell anything; merely ‘warehouse’ the assets and distribute them as need to whomever needs them.

 

Numerous companies showed real-time MPEG encoders, among them Z3 Technology, Visionary Systems, Haivision, Vbrick, Adtec, Black Magic Designs, and (of all people) Rovi, otherwise known for their electronic program guide software. Many of these encoder boxes can accept analog video (composite and component) as well as HDMI and DVI inputs. The general idea appears to be ‘plug-and-play’ encoding for IPTV streaming across a broad range of markets. The Black Magic encoder was the cheapest I’ve seen to date at $500, while price ranges on other models ranged as high as $9,000.

A Tektronix monitor for color anaglyph 3D? REALLY?

Do NOT let your children get any ideas from this photo...

Tektronix had one of the funnier (unintentionally) demonstrations of test and monitoring gear. A new combination monitor, the WFM300, has a color anaglyph mode where you can see the interocular distance for red and cyan color anaglyph program material. Never mind the fact that color anaglyph isn’t being used for much of anything except printed 3D these days, so what were the folks at ‘Tek’ thinking?

 

Finally, Sony showed they can be all wet but still on top of things with their demonstration of an HXR-NX70U 1080p camcorder operating normally while getting a pretty good hosing. The camera is completely water-sealed and dust-sealed for use in hostile environments, and records to internal hard disc drives and memory cards. The shower ran continuously during the show and the camera never even hiccupped. Fun stuff!

Can You Cut the Cord and Still Find Happiness in TV Land?

The newspapers have been full lately of stories that (a) claim cord-cutting will have no impact on pay TV viewing, or (b) show an increasing number of TV viewers are dumping (or strongly considering dumping) cable TV packages in favor of broadband video, or broadband plus over-the-air digital TV.

On the “it’s no big deal side,” you’ll find ESPN and Frank Magid Associates, while the “cord cutting is a growing trend” camp is represented by Parks and Associates, Time Warner, and SNL Kagan. While both sides acknowledge that the pay TV industry suffered its first-ever net loss of subscribers from April to September of this year, they disagree on the reasons.

ESPN and Magid claim that the total subscriber churn is less than 1%, and may be as low as one-quarter of one percent. They attribute the drop-off to the recession and expiring triple-play special deals. Parks points to the explosion in sales of Internet-connected TVs (NeTVs) and connected Blu-ray players and DVRs. Time Warner, in the meantime, just launched a lower-price basic “popular demand” channel package to hold on to subscribers, and will be followed by Charter Communications shortly.

Time for some clarity! According to a story on paidContent.org, Needham & Co. analyst Laura Martin reported the results of a simple request she made of 300 respondents in October: “Please list which TV channels you must have available online in order for you to turn off your pay TV subscription.”

Guess who sat at the top of the list? CBS, named by 35% of respondents. The #2 slot was filled by ABC (right behind at 34%), while Fox was in a tie with NBC at 31%.

The highest-rated pay TV network was (no surprise) ESPN, listed by 27% of respondents. The rest of the top ten was made up of Discovery (19%), History Channel (14%), HBO (11%), Comedy Central (10%), and The Food Network (also 10%).

It’s interesting that the top four networks are also available in many markets for free as over-the-air digital TV broadcasts. That also may explain why some cord-cutters are quick to dump cable TV and get their TV fix with antennas and a broadband connection.  (For what it’s worth, PBS finished in a seven-way tie with The CW, MTV, HGTV, CNN, Lifetime, and Bravo.)

The paidContent article comments that most respondents who voted for at least one over-the-air TV network also listed the rest of them. “Most folks think of the four broadcasters as a monolith,” said Martin. “This may be because consumers actually watch shows on all four broadcast networks, or it could be because they have no idea which network their favorite shows are on.”

For viewers who live near major cities, it’s not unusual to have as many as 30+ minor channels of free, over-the-air programming available. Those viewers are also more likely to have fast broadband, so cutting off cable or satellite TV still leaves them with plenty of program choices…and apparently, their ‘can’t live without’ TV networks as well.

So yes, you can find some happiness in the world of free TV…so long as you are willing to part with a few cable and satellite networks, and have a good broadband connection for Hulu, Netflix, YouTube, and other Internet TV channels.

To Readers: How about you? Would you be willing to drop cable or satellite TV, and just live with what you can watch using an antenna and a fast Internet connection? Or maybe you’ve already cut the cord? I’d like to hear your comments one way or the other.

3D over broadcast digital TV: Can it be done right now?

I’ve been asked more than a few times this year if it is at all possible to transmit 3D over digital terrestrial television broadcasting (DTTB), or what we know simply as “free digital TV.” There seems to be a perception that one must have a Pay TV subscription service (cable, DBS, FiOS, or U-Verse) to access 3D programming.

Believe it or not, carrying 3D over terrestrial broadcast stations is mostly a business decision. Yes, major TV networks like CBS, NBC, Fox, and ABC could start broadcasting programs in 3D right now. And your 3D-enabled TV would be able to process the 3D signals correctly so the programs can be watched with active-shutter glasses. (I’m not going to discuss color anaglyph 3D here, which works over any TC channel, but produces the lowest quality of 3D.)

The ‘catch’ is that the 3D content would have to be delivered in a frame-compatible format, such as 720p/60 top + bottom (like ESPN uses), or 1080i/30 side-by-side (like DirecTV uses). Both of these formats were specifically developed to fit in a standard 6 MHz channel space, using a maximum bit rate of about 19.39 Mb/s. And in fact, broadcasts of 3D content from earlier this year were delivered in the MPEG2 format that is standard for over-the-air digital TV.

The top + bottom format used for 720p/60 frame-compatible broadcasts.

The fact that cable companies and satellite broadcasters are now moving to MPEG4 encoding for 3D carriage shouldn’t be discouraging. MPEG4 (more specifically, H.264 AVC) provides for 50% compression efficiency over MPEG2. But broadcasters can still pipe a pretty good 3D signal into your home using MPEG2, which has also gotten a lot more efficient in the nearly 20 years it’s been around.

Remember that both of the frame-compatible 3D formats sacrifice some image resolution to fit within a standard channel width/bit rate constraint, no matter what service you get 3D from. For top+bottom, your TV receives a combination frame with two 1280×360 images, anamorphically squeezed in the vertical plane. For side-by-side, each frame of video provides a pair of 960×1080 images, anamorphically squeezed in the horizontal plane.

Your 3D TV separates the two frames and reverses the anamorphic squeeze with a stretching process, resulting in full left eye/right eye frames – albeit with somewhat lower resolution. But today’s TVs do a pretty good job of interpolating pixels to correct for de-interlacing and judder, so these half-resolution images don’t look nearly as bad as you might think.

The side-by-side 1080i/30 format used for 1080i/30 broadcasts.

So, what’s holding broadcasters back? For one thing, available bits! DTTB is limited to a maximum bit rate of 19.39 Mb/s, and that leaves just enough room for one full HD channel (15 Mb/s maximum bit rate) and perhaps a standard-definition channel (3 MB/s maximum bit rate) to go along with it. So a broadcaster would have to devote the entire HD bit rate to the 3D program. Jamming a second 720p/60 or 1080i/30 3D program alongside the standard 2D broadcast would not be practical, as image quality on both channels would suffer.

Another possibility would be to transmit a 2D signal (left eye) and carry the right eye signal as a separate program. This would be a similar approach to analog FM stereo broadcasts, where the stereo information is transmitted as a subcarrier, or analog color TV, where the color burst is also carried as a subcarrier.

This technique can be accomplished digitally by transmitting a full-bandwidth 2D signal (left eye) and carrying additional metadata (2D + depth information) required to create the stereoscopic effect. That metadata would add something to the payload, and would rely on the some of the image processing inside the TV.

Now, a broadcaster could carry the Super Bowl in full HD as before (720p or 1080i), yet still enable 3D viewing for TVs equipped to handle the 3D signal. But there’s another ‘catch:’ Your TV would have to recognize the metadata ‘package’ and be able to open it up, rebuild the right eye frames, and sequence them accordingly.

Because it’s not likely that a DTTB station would use its entire bandwidth to carry a 3D broadcast of a big event, the 2D + depth format would make the most sense, just as older black and white TVs could still display a color TV program simply by ignoring the chrominance signals. I don’t know of any consumer TVs that are equipped to handle the 2D + depth format, so some sort of outboard adapter would be required to make this work.

The good news is that such a 3D converter box would not have to be expensive. It would incorporate an ATSC tuner (maybe even a pair of tuners!) and would be equipped to process the DTTB 3D signal into top + bottom or side-by-side formats, using a standard HDMI output connection to the TV. Frankly, such a box ought not to cost much more than $100, and could also be sold as a bundle with one or two pairs of universal active shutter glasses. (Motorola showed a prototype 3D converter box at NAB 2010 for older, non-3D TVs.)

What programs would work in 3D? Aside from football, which I do not believe benefits much from 3D based on my recent experiences, I’d say basketball, hockey, auto racing, Olympics individual events, golf, and tennis. Basically any sports event where the camera can get close enough to realistically create a sense of depth.

Who would be likely to try 3D broadcasts? My guess would be ABC and Fox for starters, given how much sports programming these networks already carry and how many stations they own. ABC, of course, is part of Disney, who also owns ESPN. ABC has the NBA, college football, and the Indianapolis 500, while Fox operates an extensive sports division and covers college and pro football, auto racing, and major league baseball.

NBC might also dip their toes in the water with Olympics coverage, Notre Dame football, NASCAR, horse racing, and Sunday Night Football. I’d see CBS as the last network to try this out, simply because they adhere to a strict ‘no multicast’ policy at all of their owned-and-operated (O&O) CBS and CW stations.

So the answer to the question is “Yes, free TV stations can broadcast 3D programming, and they can broadcast it now.” The catch is, do they want to, and which delivery format would they adopt to make it work?
