Abstract:
1. A method of synchronizing presentation of a media program on a plurality of wireless transmit/receive units (WTRUs), the plurality of WTRUs including a first WTRU and a second WTRU, the method comprising: the second WTRU replicating the presentation of the media program from the first WTRU onto the second WTRU at least in part by receiving a networked bookmark from an Internet Protocol (IP) Multimedia Subsystem (IMS) network, wherein the networked bookmark comprises an identification of the media program, a bookmark-created time, a first offset, and a suggested presentation offset, wherein the bookmark-created time indicates a time at which the bookmark was created at the first WTRU, wherein the first offset indicates an offset in time from a beginning of the media program, and wherein the suggested presentation offset indicates an offset in time from the bookmark-created time to a bookmark presentation time at the first WTRU; the second WTRU determining a second-WTRU-presentation offset equal to a current wall-clock time minus the bookmark-created time plus the first offset minus the suggested presentation offset; and the second WTRU presenting the media program with the determined second-WTRU-presentation offset from the beginning of the media program.
