ABSTRACT:
An image signal compression transmission system for transmitting and receiving a compressed image signal, having a transmitter section which entropy codes digitized image data for transmission, a transmission channel through which entropy-coded codes sent from said transmitter section are transmitted, and a receiver section which decodes said entropy-coded codes received from said transmission channel and derives an original digital image signal. In the transmitter section, digital image data is entropy coded. The entropy-coded codes are transmitted to the receiver section through the transmission channel. In the receiver section, the received codes are entropy code decoded at a decoding speed corresponding to a transmission rate on the transmission channel. Coefficient codes derived by the decoding are stored into a memory at the same speed as the decoding speed. Then, the coefficient codes are read from the memory at a speed different from the decoding speed, but at the same speed as a signal processing rate in a signal processing system subsequent to the memory.
