摘要： A method and nodes in a communication network (305) for controlling multi-cast delivery of files, wherein the multi-cast delivery is adapted to reduce the amount of required uni-cast file deliveries in the communication network. A browser of an IPTV Terminating Function (ITF; 310a, b, c), requiring a file interrogates a cache (316) of the IFT for the file content before a uni-cast request for file delivery is sent to an Application Service Platform (ASP;300).. The files stored in the cache have been previously delivered to the IFT via the proposed multi-cast mechanism. If the file content is not stored in the cache, a uni-cast request is sent to the ASP. Each uni-cast request is also forwarded to a Multi-Cast Controller (MCC;320), which determines whether the requested file should be sent also to a plurality of additional IFTs on a multi-cast channel. At each IFT, listening to the multi-cast channel, the received content can be handled selectively -according to a filtering mechanism, and a received file may, e.g. be stored in the cache for later retrieval.
摘要翻译：用于控制文件的多播传送的通信网络（305）中的方法和节点，其中所述多播传送适于减少所述通信网络中所需的单播文件传送量。 IPTV终端功能（ITF; 310a，b，c）的浏览器要求文件在文件传送的单播请求发送到应用服务平台之前询问文件内容的IFT的高速缓存（316） ASP; 300）。存储在缓存中的文件以前已经通过提出的多播机制传送到IFT。如果文件内容未存储在缓存中，则会将单播请求发送到ASP。每个单播请求也被转发给多播控制器（MCC; 320），多控制控制器（MCC; 320）确定所请求的文件是否也应发送到多播信道上的多个附加IFT。在每个IFT处，监听多播信道，可以根据过滤机制选择性地处理所接收的内容，并且所接收的文件可以例如被接收。存储在缓存中以供以后检索。

摘要： A method of managing a unicast-based media session is disclosed. A user terminal (100) having access to channel identifiers of media channels (400, 410) available at a media server compiles a SIP- based channel request comprising a channel identifier of one of the available media channels (400, 410) and a port identifier of at least one media input port of the terminal (100). This message is sent to a network node (200, 300) for initiating delivery of media data of selected media channel to the announced media input port (115). The SIP-based data signaling also allows switching between unicast- based media channels and switching between unicast-bast and multicast/ broadcast-based media channels during the ongoing media session.
摘要翻译：公开了一种管理基于单播的媒体会话的方法。具有访问在媒体服务器可用的媒体信道（400,410）的信道标识符的用户终端（100）编译基于SIP的信道请求，该信道请求包括可用媒体信道（400,410）之一的信道标识符和端口终端（100）的至少一个媒体输入端口的标识符。该消息被发送到网络节点（200,300），用于发起所选择的媒体信道的媒体数据到所宣布的媒体输入端口（115）的传送。基于SIP的数据信令还允许在正在进行的媒体会话期间在基于单播的媒体信道之间切换和基于单播和基于多播/广播的媒体信道之间的切换。

摘要： An algorithm for video summarization is described. The algorithm combines photometric and motion information. According to the algorithm the correspondence between feeature points is used to detect shot boundaries and to select key frames. Thus, the rate of feature points, which are lost or initiated, is used as an indication if a shot transition occurred or not. Key frames are selected as frames where the activity change is low.
