700 MHz Groundhogs Look For DTV Shadow

Groundhog's Day is the traditional time for reading the shadows of things to come. This year is no different, as a shivering continent holds its icy breath in anticipation of a warm weather bailout courtesy of Punxsutawney Phil. But there's another shadow on the horizon being eagerly watched by the telecom industry. That's the looming decision on user rights to the 700 MHz UHF TV band. If it goes one way, DTV or digital television will soon be here. If it goes the other, we'll have another 16 weeks of ATV or analog television.

"Who cares," you say? Lots of people care about this decision. Probably a lot more than really think that dragging a groggy rodent out of bed is actually going to stop their teeth from chattering. On the one side are those who's TV sets are going to become nothing more than hiss generators when the analog television transmitters are shut down for good. On the other side are the new owners of those TV frequencies who bought and paid for the right to re-purpose them in a recent government auction. Somewhere in the middle are the television stations themselves who resent having to pay the electric bill for both an analog and a digital TV transmitter, but have taken their time upgrading to HDTV local programming.

What's behind this conundrum is an unprecedented massive repurposing of the broadcast spectrum. Analog TV, which was first demonstrated during the Hoover administration and rapidly deployed after the Second World War, is being frog-marched off its traditional VHF and UHF channels in favor of digital TV and other applications such as cell phones and wireless broadband Internet service.

What's so unprecedented about this is that technology improvements have always had to work with existing communications services on the public airwaves, not evict them. AM radio started up in 1920 and is still with us. The band has been expanded and stereo was introduced. There's even digital radio called HD radio. But your old crystal set will still pick up the first U.S. broadcaster, KDKA, at 1020 on the dial near Pittsburgh and farther away after dark. When FM came along, new radios had to pick up both AM and FM channels. Most still do. When the VHF TV channels filled up, new TV sets had to receive both VHF and UHF. They still do. Color came to television only after some clever engineers figured out how to squeeze in the color signal so that B&W receivers ignored it and color sets automatically displayed full color pictures. They still do.

This time it's different. Only a couple of years have elapsed since TV receivers were mandated to pick up both analog and digital signals. That would be well and good if the analog channels were going to keep broadcasting. Then it wouldn't matter that your old TV set lived forever. You'd still be able to watch your programs and could upgrade with a converter or new HDTV set when you felt like it and had the money available. But pulling the rug out on analog TV owners by pulling the plug on their analog signals forces people to either toss out perfectly good television sets, buy a converter set for each, or add to their collection with new digital TVs.

The government meant to ease the pain by providing coupons in the form of single use "gift" cards to offset the cost of buying converters. But underfunding and slow response by consumers in understanding that "the end is near" means that today there are several million people on a waiting list for the coupons that may never come. You have six TVs scattered around your house because television sets are relatively cheap? Too bad. You only get coupons to upgrade two of them, if coupons ever become available again.

The other problem is that digital TV reception is more finicky than analog. Analog can be weak, but watchable, and you can tinker with your antenna to get the best reception. Digital is either there or not. If your antenna isn't set just right, you'll be climbing on the snowy roof in freezing February to make adjustments. Who's bright idea was it to do this transition in the middle of winter?

Delaying the demise of analog TV until June 12 coupled with sending out millions more converter coupons seems like a good way to create a second chance to do it right the first time. Consumers get a "last call" to buy converters, upgrade to HDTV sets, or order alternative delivery services such as satellite or cable. Dish Network or DirecTV installers will be able to put a dish on your roof without risking an icy fall. Cable TV installers will be able to trench cable in the unfrozen soil of your back yard. You can tweak your antenna or have a new one (with a rotor) installed in the warmth of the spring sun.

So who's opposed to this seemingly sensible digital TV delay? Qualcomm, for one, is hopping mad that they won UHF channel 55 in the auction and have installed 100 new transmitters around the country to provide 15 channels of their MediaFLO mobile video programming to wireless subscribers. Not being able to flip the switches of those transmitters to ON until summer means no way to add paying subscribers, and that's an immediate loss of planned revenue.

AT&T and Verizon also have digital dogs in this fight. Theirs are called LTE or Long Term Evolution, a cellular broadband standard that can bring 10 Mbps to 100 Mbps Internet connections to smartphones, laptop computers and even residential and small office desktops. But this technology is, indeed, something of a long term evolution from the HSUPA and EVDO broadband networks they have deployed to date for cellphones and aircards. Both carriers have said that a short delay won't significantly impact their buildout plans that were planned for later this year and beyond.

TV broadcasters would like to stop feeding gross numbers of kilowatts to their aging analog transmitters to reduce their power bills. That's understandable. Some stations are also caught in a TV channel version of musical chairs. They've got low power digital transmitters propped up to get in the digital game on a borrowed channel. But they can't get their full power digital transmitters on the air until the analog transmitter vacates their permanent channel. Stations that took the option of switching channels for digital service don't have that particular problem.

There are also the slippery-slopers who fear that once you delay a schedule you may never make the change at all. The transition date will just slip away 3 months at a time. Well, you can't say it absolutely won't happen. But once the majority of consumers are satisfied, it seems likely the government will exercise its eminent domain powers to get the switch over and done with.

At this writing, the weather prognosticating groundhogs are prepping for their big announcements on the arrival of Spring. Our Congressional leaders are prepping for another vote on the DTV transition delay and will have their own announcement, likely this week. No matter how any of these predictions come out, chances are that someone's going to be getting a cold shoulder long before the tulips bloom.

Keith and Bill-O on the Small Screen

Probably the best running feud on news television is the dustup between Keith Olbermann and Bill O'Reilly. Keith to the left. Bill to the right. Stand-up, sit down, fight, fight fight! Can you bear to miss even one minute of it?

Well now you don't have to. MediaFLO USA is bringing three 24/7 news channels to its lineup of mobile TV programming viewable on your compatible cell phone. They are MSNBC, CNBC, and FOX News.

If you watch any or all of these powerhouse news channels on cable or satellite, you may suffer pangs of withdrawal when you're away from home. Especially if there is some big story breaking or you need to be out when your favorite program airs.

How about that stock market? Active investors will enjoy having "Squawk Box," "Mad Money with Jim Cramer" and "Power Lunch" on CNBC with them so they can get the latest take on the market's moves and investment suggestions.

Politicos will get to carry "Countdown with Keith Olbermann," "Hardball with Chris Matthews" and "Morning Joe" on MSNBC and/or "FOX & Friends," "The O'Reilly Factor with Bill O'Reilly" and "Hannity & Colmes" on FOX News.

But wait, it gets better. The way this works is that the programs seen through MediaFLO's mobile TV broadcasts are aired simultaneously with those on regular broadcast services. In other words, the big tube and the little tube will be in sync. It's literally like carrying your TV with you. Pull up the little whip antenna and watch wherever you happen to be.

Well, wherever is perhaps an overstatement. MediaFLO service, as offered by AT&T and Verizon Wireless, is available in 58 major metropolitan areas nationwide. That's many of the big cities, but not out in the boonies or small town America. Well, not yet anyway. If this takes off, you can bet that both wireless service providers will be swamped with demands for greater coverage.

MediaFLO mobile broadcasting differs from cellular broadband downloads in that it is an actual over-the-air digital subscription TV service transmitting on reserved channels in the UHF band. You're not downloading clips or watching IPTV. It's regular television programming formatted to look good on a much smaller screen. As an independent system, mobile TV doesn't use your cellular minutes while you're watching.

In addition to these new offerings, MediaFLO USA has full-length and simulcast programming from CBS, CBS College Sports, CBS News, Comedy Central, ESPN, FOX, FOX Sports, MTV, NBC 2Go, NBC, NBC Sports, NBC News, NickToons and Nickelodeon. There much be something in there that you can't live without.

So, how do you get this mobile TV service. First, you need a compatible cell phone that has the extra circuitry needed to pick up the MediaFLO signal. That includes the LG Vu and Samsung Access for AT&T wireless service. For Verizon, you'll need a Samsung SCH U620, LG VX9400, LG Voyager or Motorola RIZR Z6TV. You'll recognize these as the latest high performance multimedia phones available from the major manufacturers. You'll also need a subscription to AT&T Mobile TV or Verizon's VCAST Mobile TV, depending on which cellular service you have. Note that programming selections are subject to change.

Interested in mobile TV? You'll find phones and service plans at Cell Phone Plans Finder that include MediaFLO capable handsets, as well as many excellent deals on multimedia, business and basic personal cellular phones.

Media Flos to Mobile TV

LG VX9400 MediaFLO enabled phone for Verizon.Television is pervasive. Once limited to high power over-the-air broadcasting, TV has been glomping onto other delivery mediums as fast as it can find them. First came cable channels that had no over the air equivalents. Then satellite, with its almost universal reach. Next, the Internet with clips on YouTube and IPTV feeds from network owned Websites. Now the move is to cell phones and other wireless devices for truly mobile TV.

The original approach to mobile video was downloadable clips using the cellular broadband networks, such as EV-DO for Verizon and Sprint. But cell phone network operators are running into the same limitations as Internet content delivery. The available bandwidth isn't high enough for really good real-time video presentation, and the sheer volume of packets threatens to bring down the whole network if the service truly catches on. What's been needed is a new delivery network designed for video from the ground up.

The leading candidate for that new network is Qualcomm's MediaFLO. Verizon Wireless started adopting it about a year ago and AT&T has just announced that it will begin service too. What's special about MediaFLO? First, it delivers its content using a different over-the-air channel than the cellular frequencies. Second, it's designed for real-time viewing at 30 frames per second to give a true live television experience. A typical screen size is QVGA (Quarter Video Graphics Array) at 240x320 pixels. Since mobile devices aren't likely to tote around living room sized video displays, a lower bandwidth is acceptable to provide a good viewing experience. MediaFLO needs just 300 Kbps per live channel.

The MediaFLO specification supports many possible deployment schemes, but the one that is winning out is the former UHF TV channel 55 at 716-722 MHz. It is part of the lower 700 MHz band sold to Wireless companies by an earlier FCC auction and offers licensed high power transmission with large coverage areas. With 50 KW of effective radiated power and a 6 MHz bandwidth, MediaFLO transmitters can provide up to 20 live mobile TV channels with stereo sound over a substantial service area.

Another advantage over IP and cellular broadband delivery is that FLO TV service is multicast, like regular television. That means that the same bandwidth is used regardless of how many viewers there are. Internet based services usually need a certain amount of bandwidth for each user, especially for last-mile delivery. The FLO in MediaFLO stands for Forward Link Only to designate that this is a one-way transmission system.

A typical MediaFLO enabled cell phone is the one being sold by Verizon. It's 320x240 pixel high resolution color display (262,000 colors) rotates from portrait style when used as a cell phone to a landscape mode for TV viewing. You pull up a 5 inch TV whip antenna when needed to get a strong signal. This phone also supports Verizon's V Cast video services using the EV-DO cellular broadband system with up to 700 KHz download speed.

Another MediaFLO phone for Verizon is the Samsung SCH-U620, the first one offered by Verizon for mobile television. This is a slider phone with a similar screen size and V Cast capabilities. Plus all the usual niceties such as streaming Bluetooth and a Megapixel camera.

AT&T is planning to offer two cell phones of its own that will be MediaFLO enabled. They are the LG Vu and Samsung Access.

MediaFLO is aggressively marketing its technology and adding content that now includes CBS, Comedy Central, ESPN, FOX, MTV, NBC and Nickelodeon. Coverage is still limited to major metropolitan areas, but the fierce competition that will no doubt ensue between AT&T and Verizon will likely result in additional transmission sites as cell phone users get comfortable with bringing their TV programs with them. Mobile television seems like an idea whose time has come, much like iPOD music on the go and cell phones themselves. With the completion of the 700 MHz spectrum auction, it will be interesting to see what other video and TV options become available using MediaFLO and competing technologies.
