DTS/PTS BACKWARD EXTRAPOLATION FOR STREAM TRANSITION EVENTS

摘要

In one method embodiment, receiving a video stream comprising a first compressed picture without associated time stamp information and a second compressed picture having associated first time stamp information, the second compressed picture following the first compressed picture in transmission order; deriving second time stamp information based on the first time stamp information; and processing the first compressed picture based on the second time stamp information.

主权项

1. A method, comprising:
receiving indication of a stream transition event; deriving time stamp information based at least in part locating a predetermined backward extrapolation period (BEP) value; and determining whether the derived time stamp information has expired, and responsive to the determination, reconfiguring a system time clock to match the value to enable processing of the stream transition event.
