Abstract
Content comprising audio and video may be processed by different processing pipelines, but latencies between these pipelines may differ due to differences in data compression, processing loads, and so forth. The time between entry and exit from the pipeline of a frame is measured to determine pipeline latency. The pipeline latency may be used to shift timing of audio frames, video frames, or both, such that they are synchronized during presentation.
