Claim:
1. A wireless transmit/receive unit (WTRU) comprising: a transceiver operatively coupled to a processor, the processor and the transceiver configured to exchange information elements for an inter-device collaborative multi-media session including a group identity, wherein the group identity indicates flows of the inter-device collaborative multi-media session that are synchronized; the processor and the transceiver are further configured to exchange synchronization information including the group identity and an updated time synchronization information for use in synchronizing the flows, wherein the updated time synchronization information includes a presentation time offset of at least one other device sharing the group identity associated with the inter-device collaborative multi-media session; and the processor re-synchronizing its media flow based on the updated time synchronization information, wherein the re-synchronizing updates synchronization of the flows to provide synchronized playback for the WTRU and devices associated with the inter-device collaborative multi-media session.
