Video decoding method, video decoder and digital TV system using the video decoding method and video decoder

Image Number 2 for United States Patent #6295321.

A video decoding method and apparatus using the same decode and display a compressed video bit stream output through a video buffer for temporarily storing the video bit stream. The method includes the steps of (a) receiving a single sync signal and an external command to control decoding of the video bit stream; and (b) decoding the input video bit stream, or skipping it, or waiting without decoding under the control of step (a). A video decoder of the present invention includes a decoding control section receptive to a single synchronization signal and an external command to control decoding of the video bit stream, and a video decoder for decoding the video bit stream input through the video buffer, or skipping the video bit stream, or waiting for a defined frame period without decoding the video bit stream under the control of the decoding control section.
