Abstract
An MPEG video decoder capable of preventing a buffer for storing a video stream from overflowing and/or underflowing. The video decoding apparatus decodes a coded video bit stream including a series of pictures to produce decoded pictures. The video decoding apparatus includes: a bit buffer for temporarily storing the video bit stream, a decoding circuit for receiving the video bit stream output from the bit buffer and decoding the video bit stream to produce decoded pictures, and a video bit stream control circuit for controlling an amount of the video bit stream to be supplied to the decoding circuit from the bit buffer based on an amount of data of the video bit stream stored in the bit buffer.
