Abstract: In one embodiment, a method for allowing an end user to create a comment stream synchronized to a content stream is provided. The method receives a selection of the content stream that contains video and/or audio that the end user is authorized to view. A computing device adds the comment stream composed of one or more comments that are synchronized with a timeline of the content stream without modifying the content stream. The comment stream and the content stream are stored separately. Playback of comment stream to the content stream is then synchronized.
