GSC16-GRSC9-08 JTC Broadcast JTC Broadcast • ETSI JTC Broadcast has input from ETSI Members who may be also members of a Forum e.g. WorldDMB Forum, DRM Forum, FLO Forum, and from DVB Project (specific agreement) • In this area, JTC Broadcast delivers standards on technologies such as DAB/DAB+, DRM/DRM+, DMB, DVB-T/T2, DVB-H, DVB-SH, Media Foward Link Only Halifax, 31 Oct – 3 Nov 2011 ICT Accessibility For All 2 GSC16-GRSC9-08 Recent JTC Broadcast activities Recent JTC Broadcast activities on Digital Radio on Digital Radio • Key highlights: around rich media and convergence • Looking at gaps and overlaps: – In the existing standards – With a view to providing a simpler and broader set of applications which will cover DAB, DAB+, DMB, DRM and the internet – And allow content providers to deliver content in the most efficient way to their audiences along with enhanced interactivity • The complementary DAB and DRM standards together provide a complete and integrated open digital radio platform with solutions for all available and prospective frequency bands Halifax, 31 Oct – 3 Nov 2011 ICT Accessibility For All 3 GSC16-GRSC9-08 Recent JTC Broadcast activities Recent JTC Broadcast activities on Mobile TV on Mobile TV • DVB-SH – Revision of DVB-SH standards (EN 302 583) to add new features such as low latency – Consequently, revision of DVB-SH Implementation Guidelines (TS 102 584) • DVB-T2 mixed mode (EN 302 755 version 1.3.1) – EN 302 755 adds a “T2-Lite profile” – T2-Lite profile: intended to allow simpler receiver implementations for very low capacity applications such as mobile broadcasting; although it may also be received by conventional stationary receivers. – Version 1.3.1 introduces a name, which is “T2-base profile”, for the previous single profile Halifax, 31 Oct – 3 Nov 2011 ICT Accessibility For All 4 GSC16-GRSC9-08 Recent 3GPP activities on MBMS Recent 3GPP activities on MBMS • Rel 11: – Radio Improvements (lead by RAN2 and RAN3) on Service continuity for MBMS for LTE – Discussions in SA1 on starting the work on converged mobile broadcast support for LTE, as to investigate the feasibility of a common broadcast specification which can be used in a 3GPP network and a broadcasting network that is based on DVB or other similar standards. • No agreement yet, so no work started. Halifax, 31 Oct – 3 Nov 2011 ICT Accessibility For All 5 GSC16-GRSC9-08 3GPP IMB 3GPP IMB • 3GPP IMB (Rel 8): – Introduced in Rel-8, “IMB” stands for “Integrated Mobile Broadcast” or, in full, “3.84 Mcps TDD MBMS over a Single Frequency Network (MBSFN) IMB”, formerly known as Downlink Optimized Broadcast (DOB) – It allows the use of the TDD spectrum (to date, widely unused by the operators) for deployment of broadcast applications, as to offer capacity relief to the FDD channels – Alignment with FDD WCDMA is maximised as to allow for simple multimode terminals and to offer smooth handover between IMB and FDD. – IMB can be used for all “classical” broadcast services, e.g. interactive TV, podcasting, public safety alerts, etc – No further standardization since Rel-8 – Inter-operators trials performed earlier this year in UK to test services such as mobile TV.
