Companies that make screens for mobile devices have been working hard to make high-resolution screens ever smaller. These will allow users to watch video on their mobile phone. However, the average user isn’t going to take the time to download a movie onto their smartphone. Thats’ why handset makers want to build TVs directly into their products.
Currently, this isn’t very practical because the required components are so large. Texas Instruments believes it has the solution for this. It is working on a digital TV receiver on a single chip for phones and other mobile devices. This will capture broadcast signals and allow users to watch live broadcasts.
Code-named “Hollywood,” the chip will use the new television infrastructure that is being developed for cell phones.
“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,” said Gilles Delfassy, a TI senior vice president. “With this new chip on the cell phone, users will enjoy digital, high-quality TV in real-time.”
New TV Infrastructure
This TV chip will support newly established TV broadcast standards. While no single standard will be used worldwide, TI believes that the most prevalent standards will be Digital Video Broadcasting – Handheld (DVB-H), which was developed for Europe and is expected to extend to North America, and the Japanese specification, Integrated Services Digital Broadcasting – Terrestrial (ISDB-T). The Hollywood chip will support both DVB-H and ISDB-T.
Dedicated wireless networks supporting these standards will feature high-quality live broadcast TV (24-30 frames per second) paired with full audio, significantly better than what is possible now over cellular networks.
These networks also could support services like pay-per-view programming, interactive television, and menu/guide systems.
More about Hollywood
Instead of the traditional three-chip solution, which includes a tuner, OFDM demodulator, and channel decoder processor, Hollywood will be to the industry’s first single chip for digital TV phones.
Hollywood will work with TI’s widely-adopted OMAP processors, which will handle the multimedia processing of TV content.
As promising as this news is, it’s much to early to toss out the TV now. TI expects to provide samples of the Hollywood chip to customers in 2006.
