3GPP supports High Efficiency Video Coding
3GPP Release 12 specifications now include support for the HEVC (High Efficiency Video Coding) video codec – H.265, providing a technical solution for highly efficient delivery of download, streaming and conversational video services.
Addressing the challenge of ever growing video traffic over mobile networks, HEVC provides a remedy for operators to increase quality of experience while at the same time reducing bandwidth consumption of video services, typically by a factor of 2 compared to the best technologies available prior to Release-12.
3GPP SA4 - the Codec working group - completed their study of the compression efficiency of HEVC in the context of 3GPP services by conducting objective and subjective tests, producing the 26.906 technical report to document the findings. Accordingly, the HEVC video codec is specified with decoding capabilities conforming to the Main profile, Main tier, up to level 3.1 thus allowing HD video services in 720p up to 25 or 30 frames per second.
3GPP video services like HTTP and RTP-based streaming (3GP-DASH, PSS), broadcasting/multicasting (MBMS), download and progressive download (3GPP file format) and messaging (MMS), but also Multimedia Telephony Services over IMS (MTSI) and IMS Messaging and Presence all support this video codec and dedicated signaling in the new 3GPP Release 12.
The updated specifications bringing support for HEVC into 3GPP are:
TS 26.114 |
IP Multimedia Subsystem (IMS); Multimedia telephony; Media handling and interaction |
TS 26.140 |
Multimedia Messaging Service (MMS); Media formats and codecs |
TS 26.141 |
IP Multimedia System (IMS) Messaging and Presence; Media formats and codecs |
TS 26.234 |
Transparent end-to-end Packet-switched Streaming Service (PSS); Protocols and codecs |
TS 26.244 |
Transparent end-to-end packet switched streaming service (PSS); 3GPP file format (3GP) |
TS 26.247 |
Transparent end-to-end Packet-switched Streaming Service (PSS); Progressive Download and Dynamic Adaptive Streaming over HTTP (3GP-DASH) |
TS 26.346 |
Multimedia Broadcast/Multicast Service (MBMS); Protocols and codecs |
