VIDEO DECODING AND DISPLAY TIMING CONTROL METHOD AND APPARATUS THEREFOR

摘要

PURPOSE: A method and an apparatus for controlling video decoding and output timing are provided to control decoding and outputting timing of continuous B pictures by using one frame as a memory size for decoding and outputting the B picture. CONSTITUTION: A B picture included in an input video bit stream is decoded on the basis of previous I(Intra-coded) and P(predictive-coded) pictures and the next I and P pictures. The decoded B picture data of one frame are stored on a memory(120). A decoding controller(130) controls a decoding operation for the B picture by comparing a decoding process with an outputting process when the decoded B picture data of one frame are outputted from the memory(120).
