WIRELESS TRANSMITTING/RECEIVING SYSTEM FOR SOLVING TIME DELAY BETWEEN VIDEO SIGNAL AND AUDIO SIGNAL BY ENCODING/DECODING AUDIO/VIDEO SIGNALS THROUGH THE SAME PATH

摘要

PURPOSE: A wireless transmitting/receiving system for solving time delay between video signal and audio signal are provided to encode/decode audio/video signals through the same path, thereby capable of removing the time difference between audio and video. CONSTITUTION: A tuner member(210) tunes the broadcasting signal of the selected predetermined channel. A TS(Transport) change member(230) extracts a baseband signal from the broadcasting signal tuned by the tuner and produces a transport stream by encoding the baseband signal or outside video/audio signals as a predetermined format. A transmission module member(290) modulates the transport stream produced by the TS change member to a wireless signal with a predetermined bandwidth. The TS change member includes an IF(Intermediate Frequency) processing member(232), an analog decoder(234), an audio ADC(Analog Digital Converter) member(236) and an encoder(238).
