ABSTRACT
In October 2003, Vodafone KK of Japan introduced a mobile phone with an analog TV tuner, the V601N from NEC (Fig. 5-1). The mobile phone could be used to receive analog NTSC broadcasts from local stations. In 2004 Vodafone KK extended the range of phones with the announcement of Sharp mobile phones V402SH and V602 SH. The V402SH has a QVGA LCD display with 320 260 pixels capable of displaying 30 frames per second, i.e., the normal telecast frame rate. The tuner in these phones is designed for NTSC reception. The phone also has an FM tuner to receive FM broadcasts. The V602SH is a 3G phone. The phones are capable of receiving analog TV broadcasts from the local station. Similar handsets are available for receiving PAL broadcasts. Pocket PCs are available with Windows Mobile OS and SDIO tuner for PAL and NTSC. If mobile phones can receive analog terrestrial broadcast stations, just as they do FM stations, why do we need new technologies for mobile TV?
