摘要: An interframe coding system for frame-to-frame coding of an input signal (12), having a local decoding loop which includes an encoder (4) for interframe coding the input signal, decoding means (5) for producing a decoded signal (18), and a frame memory (1) which receives the decoded signal and outputs a predicitive signal (14). The system further comprises a controller (21a) for receiving the input signal and the predictive signal from the frame memory, for calculating a difference between the input signal and the predictive signal, for calculating a characteristic of the input signal and for generating a coding control signal (25) based on the difference and the characteristic for controlling the encoder.
