1. A method, comprising:
- processing, by a processor, a video signal having video time stamps and a video threshold time;
separately receiving, by the processor, an audio source comprising audio time stamps and an audio threshold time;
comparing, by the processor, the audio time stamps to the video time stamps;
determining, by the processor, a difference in time between one of the audio time stamps and a corresponding one of the video time stamps; and
delaying, by the processor, the audio source until the difference in time is within the smaller one of the video threshold time and the audio threshold time.

Abstract
Audio and video signals are synchronized for pleasing presentation of content. As content is streamed to a device, an audio portion may lag or lead a video portion. Spoken words, for example, are out of synch with the lip movements. Video time stamps are synchronized to audio time stamps to ensure streaming content is pleasing.
