DIGITAL SIGNAL CODING METHOD AND APPARATUS, SIGNAL RECORDING MEDIUM, AND SIGNAL TRANSMISSION METHOD FOR RECORDING A MOVING PICTURE SIGNAL AND AN ACOUSTIC SIGNAL

摘要

The present invention enables to establish a safe multiplex schedule, eliminating a signal deterioration even when a delay amount in a coded signal buffer is reduced. An input video signal from a terminal 10 is supplied to a frame memory 11. An image coding controller 12 reads in a video signal S11 from the frame memory 11 and calculates an assignment coding bit amount S12 for coding each of the pictures and a picture coding parameter S17. A video encoder 13 executes a coding processing according to these information items S12 and S17. The assignment coding bit amount S12 and the coding parameter S17 are also supplied to a multiplex scheduler 22 where a multiplex schedule is established so as to prevent destruction of a buffer of a decoder side.
