随着H.264的成熟，ITU-T VCEG开始规划H.265标准的制订。相信大家也会非常关注H.265，自然而然地会问到：H.265会在什么时候推出呢？H.265会采用哪些技术呢？
目前，ITU-T的官方网站上给出了SG16小组讨论05-08工作规划的内容，其中就有谈到对H.265的规划。关键的信息如下：
１、H.265 Final rec. 期望在2008-2010期间推出。
２、05-08开始确定H.265的需求定义及具体算法的设计
详细的内容大家可以看SG16讨论的内容：
Question 6/16 - Video coding(Continuation of Question 6/16)
- MotivationThe goal of this Question is to produce Recommendations for video coding methods appropriate for conversational (e.g. videoconferencing and video telephony) and non-conversational (e.g., streaming, broadcast, file download, media storage/playback, or digital cinema) audio/visual services.This Question will focus on the maintenance and extension of existing video coding Recommendations, and laying the ground for new Recommendations using advanced techniques to significantly improve the trade-offs between bit rate, quality, delay, and algorithm complexity. Video coding standards will be developed with sufficient flexibility to accommodate a diverse number of transport types (Internet, LAN, Mobile , ISDN, GSTN, H.222.0, NGN, etc.).
- Study Items
- New coding methods in order to achieve the following objectives:
- improvements in compression efficiency;
- robust operation in error/loss-prone environments (e.g. non-guaranteed-bandwidth packet networks or mobile wireless communication);
- reduction of real-time delay;
- reduction of channel acquisition time and random access latency;
- reduction of complexity;
-
- Organization of the compressed data format to support packetization and streaming;
- Methods to allow streams to be easily mixed by MCUs or terminals;
- Techniques to permit networks or terminals to adjust the bit rate of video streams efficiently;
- Techniques for object coding and multiview operation;
- Techniques for efficient compressed-digital to compressed-digital processing (including transcoding).
- The impact of colorimetry, video quality assessment, and quality control requirements on video codec development.
- TasksTasks include, but are not limited to:
- Maintenance of existing H-series video coding Recommendations, including H.120, H.261, H.262 | ISO/IEC 13818-2, H.263 and H.264 | ISO/IEC 14496-10;
- Extensions to H.264: 2004-2008;
- Conformance and reference software development for H.264;
- Complete requirements definition and begin detailed algorithm design for H.265;
- Final Rec. H.265: expected 2008-2010.
