Encoder and decoder to encode signal into a scalable codec and to decode scalable codec, and encoding and decoding methods of encoding signal into scalable codec and decoding the scalable codec

摘要

An encoder and decoder to encode one or more input signals into a scalable codec and to decode the scalable codec, and encoding and decoding methods using a bitstream with a layered structure in the scalable codec change a top coding bit rate to encode the input signals according to a network status, and the bitstream is decoded by analyzing the top coding bit rate included in the bitstream.
