ITU-T H.450.5-2013 (预发布)H.323的呼叫寄存和呼叫挑选辅助服务

Recommendation ITU-T H.450.5 describes the procedures and signalling protocol scenarios for the Call Park and Call Pickup supplementary services in ITU-T H.323 systems.The Call Park supplementary service (SS-PARK) enables User A (the parking user) to place an existing call with User B (the parked user) in a parking position.The call can later be picked up by retrieving the parked party from either the same terminal where the park took place or from another terminal.The Call Pickup supplementary service (SS-PICKUP) enables the picking-up user to pick up either a parked call or an alerting call.Upon successful invocation of SS-PICKUP, the picking-up user is connected with the parked user or with the calling user,depending on selection.

ITU-R BS.775-3-2012 有/无图像多声道立体音响系统

Digital TV has rapidly gained ground around the world. Several digital television broadcasting services have already been introduced in the terrestrial and in the satellite bands. As part of these digital broadcasting services, multichannel audio services are used or have been specified to enhance the directional stability of the frontal sound image and the sensation of spatial reality (ambience).

ITU-T H.780-2012 数字标牌:服务要求和基于交互式网络电视(IPTV)体系结构研究组16

Recommendation ITU-T H.780 describes a general framework for digital signage (DS) services based on IPTV architecture from the viewpoint of technical and service aspects.First,DS domains,a generic DS architecture and the classification of DS services are introduced.As technical IPTV specifications are close to those of DS,a brief comparison between the two services is provided(e.g., structure of a functional group and detailed media processing).Subsequently,high-level requirements concerning DS services are described.In addition,this Recommendation contains content delivery methods and details of functionalities of both server- and client-side applications for DS services.
