Filed: 2002-11-11
Abstract: <P>PROBLEM TO BE SOLVED: To attain decoding continuously in real time independently of fluctuations in a transmission path state.  <P>SOLUTION: A digital signal is encoded into a code A with high priority (base layer) and a code B with low priority (enhanced layer). The codes A, B of each frame are alternately transmitted in one timing when a transmission rate is sufficient. The codes are transmitted in two timings when the transmission rate is low (Figure indicates a point reaching this state). A receiver side sequentially stores the received codes to a reception buffer. All the codes of each frame are extracted from the buffer and decoded by each frame. Residual amount information is transmitted to a transmitter side (timing (2)) when the storage amount of the buffer reaches a prescribed value 4. The transmitter side encodes the codes A, B by each frame until receiving the residual amount information, but encodes only the code A when receiving the information (T(4)). The receiver side extracts only the code A by each frame and decodes it.  <P>COPYRIGHT: (C)2004,JPO
