Abstract

The invention provides a stimulation TV phone which a stimulation TV chip and stimulation TV antenna is in inside, and the user not only can watch news but also can receive phone. The stimulation TV antenna can receive output signal of existing stimulation TV system, the signal is sent into the stimulation TV chip and is tuned, decoded, demodulation in the stimulation TV chip, audio and video signal is inputted into CPU and liquid crystal display module (LCM) for playing. The TV broadcast signal can drive LCD directly as an input signal of loudspeaker LCD after being processed by the decoder. The stimulation TV phone realizes that TV program can be watched from the mobile phone by loading wireless TV signal receiving chip on existing phone mainboard.
