Abstract
Method and apparatus for compressing the flow rate of data transmitted between a television transmitter and a television receiver in which data to be transmitted is received at a differential coding device which includes a predictor, a quantizer, a transmitted data reconstruction device, and a code allocator. Pseudo-random data is added to the data to be transmitted in order to make the quantization levels of the quantizer fluctuate about a mean position. Upon reception, the received data is received at a differential decoding device which includes a code converter, a predictor, a transmitted data restoration device, and a digital filter. The received data is filtered to eliminate unwanted granular noise while retaining the image contours of the transmitted image.
