Mobile DTV 'Dyles' Up 2012 Devices


LAS VEGAS - The ATSC Mobile DTV Standard will transform into a multifaceted platform replete with conditional access security, device authentication and backchannel communication access this week at International CES.

The long-planned new capabilities were established as part of the two platforms being developed through separate broadcaster groups - the Mobile Content Venture (MCV), which developed its Dyle system, and the Mobile 500 Alliance, which is working on its own similar platform due for a fourth-quarter introduction from its 420-member TV stations.

The two systems are not expected to interfere with each other, and will require some form of backchannel capability for device authentication and a variety of interactive capabilities.

The first fruits of those systems were ready for primetime Sunday night at the CES Unveiled event, and will be on display through the show in the Mobile DTV TechZone (Central Hall 13546).

Among the new offerings are the following:

MetroPCS Communications

and the


will show live mobile digital broadcast TV services soon to be available in MetroPCS markets to customers who have purchased a forthcoming


Android-based smartphone with Dyle support.

Dyle will enable mobile consumers to watch live national and local news, sports, and entertainment programming via a broadcast television signal.

Dyle Mobile TV is the brand adopted by the MCV, which is owned by 12 broadcast groups representing 281 stations, and by two other TV broadcasters. The broadcasters plan to launch Dyle service through 72 stations that reach 50 percent of the U.S. population.


Mobile500 Alliance

has developed an application for iOS devices supporting audience measurement, EPG data, channel logos, interstitial ads and banner ads. Live recording and time shifting of over-the-air Mobile DTV content will be included through DVR-like functionality built into the app.

The system will support both in-the-clear and encrypted SD programming from up to four channels per broadcaster at a time. The alliance said it also plans to have Android adapters soon.

The initial solutions are small tuner adapter/dongles for iPhones and iPads that will run a TV app from


, incorporate an MDTV chip from


, and use


FastESG middleware. At the local television station, the MDTV head-end is powered by Expway's ESG delivery server.

Beta testing is planned to begin soon in Seattle, and a full system rollout is expected to begin in the fourth quarter.

The Mobile500 exhibit will also include

Opanga Networks

and its NetRover Mobile DVR content distribution platform, which utilizes a consumer's 3G/4G/Wi-Fi connection to pre-position movie and TV content into mobile device memory.

The alliance plans to offer a lineup of two to three local and national channels and plans to eventually expand to 15 to 20.

VOXX's Audiovox

will demonstrate an in-car ATSC-MH Mobile Video System - a self-contained blackbox solution with a built-In Wi-Fi receiver to access premium channels (gated by new conditional access security technology). The device will also permit access to all ATSC-M/H free over-the-air channels, and will periodically connect to the broadcaster via Wi-Fi hotspots and smartphones for device authentication.

Digital Stream's RCA

brand is introducing a flat-panel receiver designed for both over-the-air Mobile DTV reception and Internet connectivity.

The RCA MIT700 will be released later in the year, at a price to be announced, featuring a thin design, Android operating system and a conditional access security system.

Among other Mobile DTV announcements were a number of applications presented by

LG Electronics

, one of the core developers of the Mobile DTV platform.

LG is showing Mobile DTV applications for social-media interaction and instantaneously updated digital signage using portions of the mobile broadcast stream.

LG's Mobile DTV social-networking application would use Tweet-TV messages to interact with program content.  The broadcaster would receive the text comments, consolidate them and transmit them as conversational overlays to the TV program.
