Audio/video separator including a user data start address register

Abstract

The present invention provides an MPEG decoder which prevents user data, which is in video code data of MPEG-compressed code data, from being overwritten by the next code data before a CPU reads the user data. The MPEG decoder has an audio/video separator 3 and a memory. The audio/video separator 3 has a start code detector 11 which, in turn, has a start code start address register 12 and a start code register 13. When the MPEG decoder receives compressed code data, the start the code detector 11 searches the compressed code data for a start code specified by the start code register 13 and stores the start address of the start code into the start code start address register 12.
