Texas Instruments (TI) has developed a new single-chip processor that allows broadcast digital television signals to be received on low-cost mobile phones while maintaining long battery life and compact phone size.
TI’s Hollywood chips integrate a mobile TV tuner and demodulator into one piece of silicon using the standard 90 nanometer digital process. Consumers should expect to find the first mobile phones with the new chip by late this year.
Previously, TV functionality necessitated three individual chips to handle the RF, baseband, and memory portions of the circuit. Primary standard support for the new chip includes DVB-H, which is being deployed worldwide in Europe, the United States and parts of Asia. ISDB-T is being deployed in Japan.
DVB-H and ISDB-T use orthogonal frequency division multiplexing technology that provides good spectral efficiency and immunity to the multipath to offer improved mobile TV performance. In addition, the Hollywood design is compatible with TI’s family of OMAP applications to deliver high-quality video and stereo audio.
