Media Delivery Related Standardization in 3GPP and OMA – Short Update Frank Hartung Ericsson Research, Aachen Frank.Hartung@ericsson.com
Very short update on … • 3GPP PSS (Streaming) • 3GPP MBMS (Cellular Broadcast) • 3GPP DIMS (Dynamic Interactive Multimedia Scenes) • 3GPP MMTel (MoIP) • OMA BCAST (Mobile TV) • OMA DRM (DRM)
3GPP PSS • “Packet-Switched Streaming” • Meanwhile implemented in many new mobile phones • No major updates since last report given here • Work on some minor updates ongoing, e.g. • Adjustments to allow MBMS transmission using PSS • Align media codec configurations to available bearer rates • Improve the interactivity between the client and the server. • File format enhancements (carriage of DIMS etc) • Improve switching time between channels
3GPP MBMS • “Multimedia Broadcast Multicast Service” in 3G • One radio bearer for many mobile phones in a cell • Broadcast Mode and multicast mode • Streaming and download user services as primitives • Service protection using SIM card • Very simple user service description, no ESG/EPG ! • Rel6 ready, Rel7 with improvements (e.g. OMA BCAST alignment) • Up to 12 channels @ 128 kbps per cell, dynamic allocation between unicast and MBMS
3GPP DIMS • TS 26.142 “Dynamic and Interactive Multimedia Scenes” • Transmission of multimedia scenes • streamable • interactive • synchronization • Proposals: one based on MPEG LASeR, one based on W3C SVG 1.2 • Planned approval November 2006, currently “40% ready” • similar work item in OMA (RME, “Rich Media Environment”)
3GPP MMTel • “Multimedia telephony “services over IP, but keeping the user interface as much as possible • Work starting up (TS 26.114, “IMS Multimedia telephony; Media handling and interaction ” so far empty) • The 3GPP answer to VoIP • Work areas • jitter handling • synchronization • packet loss handling • rate adaptation • interworking with CS • interworking between radio technologies • end2end signalling
OMA BCAST • “Mobile Broadcast Services” • Common service layer “on top of” DVB-H, MBMS, 3GPP2 BCMCS • Idea is to allow service providers to provide Mobile TV over 3G and DVB networks with very little changes • In review mode, finalization expected end 2006 BCAST Service (service guide, service and content protection, interactivity, notification, roaming) 3GPP MBMS (transport, codecs [H.264 Baseline Profile], service protection) DVB-H IPDC (service guide, transport, codecs [H.264 Baseline Pr. Level 1b], service and content protection) 3GPP2 BCMCS (transport, codecs, service protection)
OMA DRM • “Digital Rights Management” • OMA DRM 2.0: state-of-the-art DRM • First implementations (Nokia N91, Sony Ericsson W850i) • First services • But: slow uptake due to pending patent licensing issue • Patent pool demands 0.65$/device and 0.25$/(user*year) for DRM 1.0 • DRM 2.1 active work item, DRM 2.2 future work item • DRM 2.1: import from other DRMs, broadcast extensions, tokens • DRM 2.2: possibility to share content between all your (and your families etc.) devices
