ETSI ETSI TR 126 903 V13.0.0 (2016-01)63GPP TR 26.903 version 13.0.0 Release 131 Scope The present document provides an analysis of the future video capability requirements o

30、f streaming and multicast/broadcast services. The purpose of this document is two-fold. On the one hand, it studies the options to upgrade the minimal requirements for video reception and decoding. On the other hand, it studies use cases for support of more advanced UEs. The ultimate target of this

31、study item is to recommend solutions for efficiently providing video support commensurate with UE and user capabilities and needs in PSS and MBMS services. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. -

40、ocument reports on a number of use-cases, considerations, and technologies. Some of these have resulted in the recommendations included in change requests to 1 and 2. 4.2 Rel 6, 7 and 8 requirements for terminals supporting H.264 in MBMS and PSS H.264 is one of the codecs defined in PSS and MBMS fro

41、m Release 6. In release 6 PSS and MBMS, level 1b is recommended. QCIF at 15Hz is a common configuration of H.264 level 1b. In release 7 and 8 MBMS and PSS, level 1.2 is recommended. QVGA at 15Hz is a common configuration of H.264 Level 1.2. NOTE: H.264 Baseline Profile Level 1.2 content is not decod

42、able by a Level 1b decoder. H.264 baseline profile is not recommended in its entirety. The “constraint_set1_flag“ should be set to 1, which implies a restricted subset of H.264 Baseline Profile. This restricted subset is also a subset of H.264 Main and High profiles. MBMS recommends only a single co

43、dec, namely H.264 Baseline profile, but other codecs that are allowed in PSS are also allowed in MBMS.

46、ec profiles and levels A single profile/level combination is defined for baseline terminals, and another for high end terminals. In other words, the present document will recommend a set of settings for baseline terminals, and a set of settings for advanced terminals. 4.3.2 Resolutions 4.3.2.1 Gener

47、al The following resolutions are examples of resolutions considered relevant for the improved video support work: QVGA (320x240) nHD (640x360) VGA (640x480) HVGA (480x320) WQVGA (400x240) SD (720x576 and 720x480) 4.3.2.2 Resolutions for PC-based UEs It is anticipated the following resolutions will b

48、e needed to support connected mobile PCs SD (720x576 and 720x480) XGA (1024768) 720p (1280720) WXGA (1366768) 1080p (19201080) 4.3.3 Bitrates Analysis should be performed between a minimum video bitrate of 128 kbps and a maximum of 384 kbps for baseline terminals, and for advanced terminals 2 Mbps f

49、or MBMS, and 10 Mbps for other cases. 4.3.4 Frame Rates Minimal Video Frame Rate 12.5Hz or 15Hz (Depending on the test sequence) Maximal Video Frame Rate 25Hz or 30Hz (Depending on the test sequence) 4.3.5 Random access point frequency For MBMS, the random access point frequency should be at least 1 per second. 4.3.6 Audio The audio is assumed to be eAAC+ Stereo Audio at 64 kbps.
