Patent number: 8832293Abstract: A computer-implemented method, apparatus, system, article of manufacture, and computer readable storage medium provide the ability to stream media content to multiple users. A first stream of/for the media content is streamed from a first location in the media content to a first user. A request is received from the first user to seek to a seek location (e.g., forward or backward) in the media content. A second location in the media content compatible with the seek location is determined. The second location is based on a second stream being streamed to one or more second users.
