Abstract

A system for transmitting and receiving video signals compressed into frequency band blocks, has an adaptive modulation circuit (410 or 450) and an adaptive demodulation circuit (520, 550). The adaptive modulation circuit (410) receives the signal blocks to obtain a block adaptive factor f1 and an index signal ID1, transmits the index signal ID1 therefor to a channel, interpolates the block adaptive so as to obtain a picture element adaptive factor, and selects a final adaptive factor among the block and picture element adaptive factors according to the video signals of the peripheral signal blocks. The adaptive demodulation circuit (520) 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.
