Claim of US Patent No. 9,369,502

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 a suggested presentation offset that indicates an offset in time from a bookmark-created time to a bookmark
presentation time at the first WTRU;

the second WTRU determining a second-WTRU-presentation offset based at least in part on 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.
