Modeo, the mobile television technology being developed by Crown Castle Mobile Media, announced 04/01/2006 that it will begin rolling out DVB-H services in the top 30 markets across the USA this year.

By 2007 Crown Castle said it will offer the service to 30 U.S. markets covering about half the population. It will feature about 10 video channels and at least 24 audio channels that can be received by cellphones, PDAs and other portable devices. Combined video and audio subscriptions are expected to cost about $15 to $20 a month while separate audio subscriptions would cost $7 to $9, said Modeo treasurer Jay Brown. Modeo has not yet signed programming deals or named cellphone provider partners.

Modeo's package of live video and audio channels is expected to be the world's first mobile broadcast network to support podcasting. Video services are designed to be broadcast in digital TV quality at QVGA resolution at up to 30 frames per second, significantly exceeding the quality offered by first generation mobile video products that used cellular channels.

Modeo plans a nationwide network of what are essentially mini television stations at 1.7 GHz using the DVB-H standard. Speculation is that Cingular and T-Mobile may use it with DVB-H phones like the Nokia's N-92 (specs).

TI showed off its new Hollywood mobile broadcast chips at CES this week (although no devices were yet available using it). Texas Instruments says it's the first in the industry to integrate the mobile TV tuner and demodulator into one piece of silicon using standard 90 nanometer digital process.

The first two products in the Hollywood mobile DTV family are:


* DTV1000 o DVB-H (digital video broadcast - handheld) which is being deployed world-wide including Europe, the U.S. and parts of Asia o Operates at 470-750 MHz (UHF) and 1.670-1.675 GHz (L-band) frequency ranges

* DTV1001 o ISDB-T (integrated services digital broadcast - terrestrial) one-segment which is being deployed in Japan o Operates at 470-770 MHz frequency range


Primary standard support includes DVB-H which is being deployed world-wide including Europe, the U.S. and parts of Asia, and ISDB-T which is being deployed in Japan. DVB-H and ISDB-T use OFDM (orthogonal frequency division multiplexing) technology which provides good spectral efficiency and immunity to multi-path to offer improved mobile TV performance.

Competitor Qualcomm Media FLO technology is said to support up to 20 streaming channels of high-quality video at up to 30 frames per second, 10 stereo audio channels, and up to 800 minutes of stored Clipcast content per day. Qualcomm said the average channel-switching time is 1.5 seconds without buffering or progress bars.

Verizon has committed to MediaFLO. Qualcomm expects to begin commercial operation of the MediaFLO System in the fourth quarter of 2006. The MediaFLO Media Distribution System, will deliver multimedia content to mobile devices in the 700 MHz spectrum for which QUALCOMM holds licenses with a nationwide footprint.

Meanwhile, MobiTV today announced the official launch and immediate availability of WiFi enabled MobiTV Service for the $300 Palm T|X handheld. The MobiTV WiFi version is similar to the MobiTV offering for Palm Treo 650 smartphones featuring a simple, TV-like interface that includes a graphical channel guide and support for channel navigation and volume control using the familiar 5-way native Palm navigation and touch screen capabilities. More than a dozen streaming video channels are available.

ABI Research projects that 250 million people worldwide will be watching movies, TV shows and "podcasts" on wireless portable devices like cellular phones and handheld organizers by 2010.

FireAnt is focused on video blogging. The "aggregator," can locate content and play it no matter what video format it's been uploaded in, including Quicktime, Window Media, or Flash. Digital cameras like the Pentax Optio S6 ($300) and A10 ($350) ability to record video and encode in DivX format.
