ABSTRACT:
A system for transmitting and receiving video signals compressed into low and high frequency band blocks includes an adaptive modulation circuit and an adaptive demodulation circuit. The adaptive modulation circuit receives the video signal blocks to obtain a block adaptive factor and an index signal ID1, transmits the index signal ID1 to a channel, interpolates the block adaptive factor so as to obtain a picture element adaptive factor, and selects a final adaptive factor f1 from either one of the block adaptive factor or the picture element adaptive factor according to the video signals of the peripheral signal blocks. The adaptive demodulation circuit converts the index signal ID1 into the corresponding block adaptive factor f1, and interpolates the block adaptive factor to produce the picture element adaptive factor, so as to selectively provide the block or picture element factor according to the video signals of the peripheral blocks.
