| Single-chip digital TV coming to cell phones |
Oct. 21, 2004
Texas Instruments (TI) says it is developing a new single-chip-digital-TV for cell phones -- codenamed "Hollywood" -- that will be able to capture broadcast signals and allow cell phone users to watch live broadcasts. The Hollywood chip will receive live digital TV broadcasts from a new TV infrastructure that is being developed specifically for TV broadcasts to cell phones, TI says.
According to TI, no single standard will be used worldwide. Instead, TI believes, the most prevalent standards will be those that are open and non-proprietary. These include Europe's "Digital Video Broadcasting, Handheld" (DVB-H) and Japan's "Integrated Services Digital Broadcasting, Terrestrial" (ISDB-T). Accordingly, Hollywood will support DVB-H and ISDB-T. TI expects first mobile digital TV infrastructure mass deployments to occur in 2007, and says that field trials are currently underway in several regions, including the US, Europe, and Japan.
Dedicated wireless networks supporting these standards will feature high-quality live broadcast TV (24-30 frames per second) paired with full audio to offer a more robust mobile viewing experience versus the one-to-15-frames-per-second streaming capability offered via cellular, TI says. These networks also could support services once reserved for the living room and bring them to the cell phone, including pay-per-view programming, interactive television, and menu/guide systems, TI says.
Hollywood, which will be implemented in TI's 90-nm silicon process, combines the functions of a traditional three-chip DTV solution -- tuner, OFDM demodulator, and channel decoder processor -- into what TI claims will be the industry's first highly-integrated single-chip for digital TV phones. Additionally, Hollywood is designed to interface with TI's OMAP system-on-chip processor technology, which handles the multimedia processing of TV content, to provide a complete TV receiver system for wireless handsets.
First samples of Hollywood are expected to be available in 2006. TI will also provide the required software for television signal processing, and it will supply a development platform that implements the Hollywood chip along with one of TI's OMAP processors in order to help handset manufacturers develop cell phones incorporating the chips.
"TI's new 'Hollywood' digital TV chip will combine the two biggest consumer electronics inventions of our time -- the television and the cell phone," said Gilles Delfassy, senior vice president and general manager for TI's Wireless Terminals Business Unit. "One by one, the industry's most exciting consumer electronics are being integrated into wireless handsets, allowing consumers to get their news and entertainment whenever and wherever they want. With this new chip on the cell phone, users will enjoy digital, high-quality TV in real-time."
