を特徴とするテレビジョン信号の符号化装置。In a device that predictively encodes and transmits a television signal, codewords with different numbers of bits are constructed depending on the frequency of occurrence of quantization levels, and the sufficiency of the memory placed between the encoder and the transmission path is determined. Accordingly, a television signal encoding device is characterized in that it allocates different code words even if the level is the same, and performs matching for sending out to a transmission path where the sampling frequency and transmission rate are not in an integer relationship.
