Visual signal coding includes the coding of: video sequences;still images;graphics;stereoscopic, multi-view, depth maps, and free-viewpoint visual information;light fields and volumetric imagery;computer displays;medical imaging.This Question will focus on the maintenance and extension of existing video and still-image 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, still-image, and other visual 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 Study items to be considered include, but are not limited to: 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, complexity, and of channel acquisition time and random access latency;organization of the compressed data format to support packetization and streaming;development of supplemental enhancement information to accompany video and image data for enabling enhanced functionality in application environments;study and specification of data for image/video annotation, indexing, and searching;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 multi-view operation;techniques for efficient compressed-digital to compressed-digital processing (including transcoding);the impact of colorimetry, video and image quality assessment, and quality control requirements on video and image codec development;computer graphics compression;security aspects that directly affect video and still-i
