Title: Picture processing method
Inventor: YOKOO HIROSHI
IPC: H04N19/91
Filed: 1993-11-08
Abstract: PURPOSE:To set properly a capacity of a memory storing coded data by setting a limit transmission capacity of one block and terminating the transmission processing of the block when the current transmission capacity reaches a set transmission capacity. CONSTITUTION:A controller 9 disregards linear quantization data sent after an actual coding capacity by a coder/decoder 7 reaches a limit coding capacity based on a preset one-block limit coding capacity and terminates the coding processing of the block. Then the coding/decoder 7 is controlled to start coding processing of a succeeding block.
