Method and apparatus for using multiple compressed digital video and audio signals |
摘要 |
The invention relates to a method and apparatus for flexibly and reliably processing one or more MPEG signals from at least one source. The method provides for synchronizing decoded streams to a reference clock, for playing multiple streams simultaneously or for transitioning between streams in a seamless manner. The output streams can have varying formats and can include both video and audio. The structure and method further provide for the capability of skipping B frames to reach a desired reference frame quickly and to edit the MPEG streams regardless of GOP size.
