Abstract
A transmitter and receiver for transmitting and receiving a plurality of image data channels as an encoded data stream. The transmitting part comprises a plurality of prefilters for reducing the resolution of each image in the image data channels, a frame memory for sequentially arranging the resolution reduced images output from the prefilters into a full resolution frame, an encoder for encoding the full resolution frame into an encoded data stream, and a transmitter for transmitting the encoded data stream. The receiving part comprises a receiver for receiving the encoded data stream, a decoder for decoding the encoded data stream and sequentially separating the decoded data stream into a plurality of resolution reduced images corresponding to the number of image data channels, and a plurality of postfilters for increasing the resolution of each of the resolution reduced images into full resolution images and outputting the full resolution images as the image data channels.
