1. A method, comprising:
- receiving, by an electronic device, a video signal having video time stamps;
receiving, by the electronic device, an audio signal comprising audio time stamps;
obtaining, by the electronic device, an amount of asynchronism permitted between the video signal and the audio signal;
determining, by the electronic device, a difference between the audio time stamps and the video time stamps; and
delaying, by the electronic device, at least one of the video signal and the audio signal until the difference satisfies the amount of asynchronism.

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 content is thus synchronized to audio content to ensure streaming content is pleasing.

8. A system, comprising:
-
a processor; and a memory storing code that when executed causes the processor to perform operations, the operations comprising; receiving a video signal comprising video time stamps; separately receiving an audio signal comprising audio time stamps; obtaining, from the video signal, a first amount of asynchronism permitted between the video signal and the audio signal; obtaining, from the audio signal, a second amount of asynchronism permitted between the video signal and the audio signal; selecting a smaller value of asynchronism between the first amount of asynchronism obtained from the video signal and the second amount of asynchronism obtained from the audio signal; determining a difference between the audio time stamps and the video time stamps; and delaying at least one of the video signal and the audio signal until the difference satisfies the smaller value of asynchronism selected from the first amount of asynchronism and the second amount of asynchronism. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A memory storing instructions that when executed cause a processor to perform operations, the operations comprising:
-
receiving a video signal having video time stamps; separately receiving an audio signal comprising audio time stamps; retrieving an amount of asynchronism from a data field in a graphical user interface; determining a difference between the audio time stamps and the video time stamps; and delaying at least one of the video signal and the audio signal until the difference satisfies the amount of asynchronism retrieved from the data field in the graphical user interface. - View Dependent Claims (17, 18, 19, 20)
