摘要
A system for presentation timing based audio video (AV) stream processing may include a switch device, a first processor, and a second processor. The switch device may be configured to route AV traffic to the first processor for processing and non-AV traffic to the second processor for processing. The first processor may receive transport stream packets that include an audio stream and/or a video stream. The first processor may receive a request to modify presentation timing of the audio stream and/or video stream. The first processor may modify the transport stream packets and/or presentation timing parameters of the transport stream packets based at least in part on the received request. The first processor may provide the transport stream packets to an electronic device. In some implementations, the second processor may be unable to access the content of the transport stream packets in the clear, e.g. due to security considerations.
