ITU-T H.263 FRENCH-2005 低比特率通信的视频编码.16号研究组

This Recommendation specifies a coded representation that can be used for compressing the moving picture component of audio-visual services at low bit rates. The basic configuration of the video source coding algorithm is based on ITU-T Rec. H.261. Eighteen negotiable coding options are included for improved performance and increased functionality. This Recommendation contains Version 2 of ITU-T Rec. H.263, which is fully compatible with the original Recommendation, adding only optional features to the original Version 1 content of the Recommendation.

ITU-T J.175 FRENCH-2005 语音服务器协议.9号研究组

This Recommendation describes the architecture and protocols that are required for playing announcements in Voice-over-IP(VoIP) IPCablecom networks. Announcements are typically needed for calls that do not complete. Additionally, they may be usedto provide enhanced information services to the caller. Different carrier service feature sets require different announcement sets and announcement formats.

ITU-T J.197 FRENCH-2005 从有线电视接入网到家庭网络的数字版权管理(DRM)桥路的高级要求.9号研究组

This Recommendation defines the requirements of a Digital Rights Management bridge from a cable access network to a home network, to which many types of content (e.g., video, audio, etc.) may be transferred by the network operator with assurance that the content is not used in a manner that is a violation of any service agreements or legal requirements.

ITU-T J.181 FRENCH-2004 有线电视系统的数字节目插入提示消息.9号研究组

This Recommendation supports the splicing of MPEG-2 streams for the purpose of digital program insertion, which includes advertisement insertion and insertion of other content types. An in-stream messaging mechanism is defined to signal splicing and insertion opportunities and it is not intended to ensure seamless splicing. As such, this Recommendation does not specify the splicing method used or constraints applied to the streams being spliced, nor does it address constraints placed on splicing devices. This Recommendation also supports accurate signalling of events in the stream.

ITU-T J.149 FRENCH-2004 视频质量度量(VQM)的准确度及交叉校正的说明方法.9号研究组

Video quality metrics are intended to provide calculated values that are strongly correlated with viewer subjective assessments. This Recommendation provides: a) methods for curve fitting VQM objective values to subjective data in order to facilitate the accuracy calculation and to produce a normalized objective value scale that can be used for cross-correlation between different VQMs; b) an algorithm (based on statistical analysis relative to subjective data) to quantify the accuracy of a given VQM; c) a simplified root mean square error calculation to quantify the accuracy of a VQM when the subjective data has roughly equal variance across the VQM scale; d) a method to plot classification errors to determine the relative frequencies of "false tie", "false differentiation", "false ranking", and "correct decision" for a given VQM.
