Abstract
A digital video processor and operating method for a receiving raw audio and video data representing images and sound to be played. The processor includes a demultiplexer for receiving the raw audio and video data and providing demultiplexed audio and video data to a memory. A first system time clock provides first time values in response to being continuously clocked by the demultiplexer. A CPU decodes and plays back the audio and video data as a function of the audio and video PTS values. The processor further includes a second system time clock providing second time values in response to being periodically incremented by the CPU. The CPU periodically sets the second system time clock to a second time value equal to a current first time value of the first system time clock in response to a standard play mode, and the CPU periodically sets the first system time clock to a first time value equal to a current second time value of the second system time clock in response to a trick play mode.
