摘　　要：目前,手机电视业务在全球非常热门。开展手机电视业务,手机必须添加调谐器、解调器、解码器等模块,接收和处理电视信号,对手机的体积和功耗提出了巨大挑战。采用特殊的手机电视终端芯片可以解决问题,是顺利开展手机电视业务的必要条件。集成单芯片手机电视终端,双模、多模芯片手机电视终端,接收模块集成于SD存储卡内的手机电视终端均已开始商用。未来,体积小、功耗低的手机电视芯片的应用,将会大大促进手机电视业务的普及。Mobile TV is growing popular worldwide. It puts new hardware requirements on the handset, requiring a tuner, a demodulator and an encoder to receive and process signals, which challenges the power consumption and size of handsets. The special terminal chip can solve these problems and stands as a prerequisite for broadcasting TV to mobile phones. Commercial mobile TV handsets have been brought to the market, which use the integrated single-chip, the dual-multi mode chip, or the TV receiver packaged in an SD card. The uptake for mobile TV services will be driven by a new generation of small and low power chips.
