Overview of Technologies for Mobile TV
Pages 44

In October 2003, Vodafone KK of Japan introduced a mobile phone with an analog TV tuner, the V601N from NEC . It could be used to receive analog NTSC broadcasts from local stations. New offerings followed such as Sharp V402SH and V602 SH. The phones have a QVGA (320 260 pixels) display capable of displaying 30 frames per second, i.e., the normal telecast frame rate. The tuner in these phones is designed for NTSC reception. Similar handsets are available for receiving PAL broadcasts. Pocket PCs are available with Windows Mobile OS and secure digital input output (SDIO) tuner for PAL and NTSC. In Europe, many handsets can receive DVB-T. The question now is very simple: If mobile phones can receive analog terrestrial broadcast stations, just as they do FM stations, why do we need new technologies for mobile TV? The answer to this question holds the key to new technologies that have emerged for mobile TV.
