Methods, systems, and products for alternate audio sources

摘要

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.
