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： The media session management of the invention encompasses a media server (200) having access to multiple unicast-based media channels and a user terminal (100). The user terminal (100) generates and transmits a generic, channel- transparent session request to the server (200). This request initiates a generic, channel-transparent media session setup procedure between the terminal (100) and the server (200). The setup procedure involves exchange of requests and responses but no media channel is yet selected or notified at the server (200). Once the channel-transparent setup has been completed, the user terminal (100) transmits a channel- specific rendering request for a desired media channel to the server (200). In a subsequent channel switch, the terminal (100) simply transmits a new channel- specific request for a new channel to the server (200) during the ongoing session and reusing the negotiated transport parameters of the channel-transparent setup procedure.

摘要： For streaming data in a mobile communication network, a descriptive file (100) of a stream (200) is provided. The descriptive file (100) comprises a list (110) of delivery source identifiers, e.g. URIs, for unicast delivery of data segments (210) of the stream. A broadcast indicator (120) is selectively added to the descriptive file (100) so as to indicate whether broadcast delivery of the data segments (210) is available. Adding the broadcast indicator (120) and initiating the broadcast delivery may be accomplished on the basis of a popularity of the stream.

摘要： The invention provides a solution for switching between channels belonging to one on-demand multi-channel streaming session. An aggregation procedure for aggregating of a number of session descriptions parameters corresponding to a multitude of channels into one single session description is proposed. Further each channel is described by a mandatory unique identifier, which can be referenced in a channel switch request and an optional human readable identifier for display in a title bar or a channel selection menu. A corresponding client application processes the SDP describing the channel bundle and uses the found information for allowing a user to switch to a channel associated with a certain identifier. Signaling of a channel switch request is done preferably via an RTSP SET PARAMETR message or as an alternative out-band via HTTP. A channel switch control unit, which is part of the multi-channel streaming server, receives a multitude of RTP flows and selects one of the flows for forwarding to the client. A switching point determination is a part of the channel switch control unit and determines the next possible point of time for switching to a requested channel. The client application receives time information for the switch point in response to a channel switch request.
摘要翻译：本发明提供了一种用于在属于一个点播多频道流媒体会话的频道之间进行切换的解决方案。提出了一种用于将与多个信道相对应的多个会话描述参数聚合成一个单一会话描述的聚合过程。此外，每个通道由强制性唯一标识符描述，可以在通道切换请求和用于在标题栏或频道选择菜单中显示的可选的人类可读标识符中引用。相应的客户端应用程序处理描述频道束的SDP，并使用找到的信息来允许用户切换到与某个标识符相关联的频道。信道切换请求的信令优选地经由RTSP SET PARAMETR消息或通过HTTP作为替代的带外进行。作为多频道流服务器的一部分的频道切换控制单元接收多个RTP流，并选择一个流以转发给客户端。切换点确定是信道切换控制单元的一部分，并确定切换到所请求的信道的下一个可能的时间点。响应于信道切换请求，客户应用接收切换点的时间信息。

摘要： A technique for controlling a download (110) of an electronic service guide (ESG) for media content distribution services to a user device (102) is proposed. First, a user behaviour related to the user device is monitored. Second, a ranking of fragments of the electronic service guide to be downloaded interactively onto the user device is determined, based on the monitoring. The download of one or more of the fragments to the user device is then initiated based on the ranking. This technique is particularly useful when a transmission capacity available for downloading fragments of the ESG is limited.

摘要： The invention is embodied in a technique for broadcasting content data from a broadcaster (including a multicaster) to a plurality of clients. After a client receives content data from the broadcaster, a plurality of available proxy servers may be contacted for post-processing after the content data broadcast is determined. The client subsequently randomly selects one of the available proxy servers to contact for post-processing after the content data broadcast. The client may further randomly select a delay time within a contact interval for the selected proxy server, at which time the client contacts the selected proxy server at the delay time to initiate post-processing.

摘要： A technique for controlling a point-to-multipoint (PTM) transmission of data over a PTM-enabled network (150) to a user group is proposed. In a first PTM transmission, a location information query message is distributed into a group service area (154). Upon receiving the query message, items of user equipment respond with location information response messages comprising location information indicative of a location of the respective user equipment. On the basis of the received location information response messages, a content transmission area (156, 157, 158) is determined. A second PTM transmission is then initiated into the content transmission area for content distribution. Furthermore, the content may be distributed via unicast retrieval.
