Abstract:
A moving image decoder for decoding encoded image data to obtain decoded image data, temporarily storing said decoded image data into a memory and reading said decoded image data as display decoded image data from said memory in order of original pictures before encoding, comprising:a first register circuit for temporarily holding a boundary address of a picture storage area within said memory;a comparator circuit for detecting coincidence of a read address at which said display decoded image data is read with said boundary address;storage means for storing a presentation time stamp PTS and valid/invalid data in correspondence with said boundary address;a switching circuit for retrieving said presentation time stamp PTS and said valid/invalid data in response to detection of said coincidence; anda time difference adjusting circuit for performing control which corresponds to a time difference between a system time clock STC and said presentation time stamp PTS retrived by said switching circuit if said valid/invalid data indicates validity.
