摘要： A multimedia provider (100) generates, based on a request for a media channel from a user terminal (10), a session set-up description that is returned to the user terminal (10). The description defines, when processed in the terminal (10), a session window (20) that is displayed on a screen (12) of the terminal and comprises a region (22) for displaying media data of a requested channel and a channel region (24) comprising information on alternative available media channels. The description also defines a binding between user inputs (14) of the terminal (10) and identifiers of the alternative channels. The set-up description allows for a user-friendly channel switch by automatically transmitting a channel switch request to the multimedia provider (100) upon a triggering of the user input (14) that is associated with the identifier of the requested media channel. The description, thus, provides a visually appealing graphical interface and simultaneously allows for a user-friendly media channel switch.
摘要翻译：多媒体提供者（100）根据来自用户终端（10）的对媒体频道的请求生成返回给用户终端（10）的会话建立说明。该描述定义了在终端（10）中处理的会话窗口（20），其显示在终端的屏幕（12）上，并且包括用于显示所请求的频道的媒体数据的区域（22）和信道区域（24）包括关于替代可用媒体信道的信息。该描述还定义了终端（10）的用户输入（14）和替代频道的标识符之间的绑定。所述设置描述允许在触发与所请求的媒体信道的标识符相关联的用户输入（14）时，自动向多媒体提供商（100）发送频道切换请求，从而进行用户友好的频道切换。因此，该描述提供了视觉吸引人的图形界面，同时允许用户友好的媒体频道切换。

摘要： A stream (1) of media frames (12-16, 22-26, 32-36) is generated by providing multiple media frames (22-26) having respective assigned default timestamps (40) defining rendering times of the media data of the media frames (22-26) according to a default rendering time schedule. Respective alternative timestamps (50) are assigned to at least a portion of the media frames (22-26). These alternative timestamps (50) define alternative rendering times of the media data of the media frames (22-26) according to an alternative rendering time schedule. The alternative timestamps (50) can be used for providing an efficient media rendering when tuning in to the stream (1) at an intermediate position of a frame grouping (20) of the media frames (22-26) thereby missing some of the media frames (22, 24) of the frame grouping (20).
摘要翻译：通过提供具有各自分配的默认时间戳（40）的多个媒体帧（22-26）来生成媒体帧（12-16,22-26,32-36）的流（1），所述默认时间戳定义所述媒体帧的媒体数据的渲染时间媒体帧（22-26）根据默认呈现时间表。相应的替代时间戳（50）被分配给媒体帧（22-26）的至少一部分。这些替代时间戳（50）根据替代的呈现时间表来定义媒体帧（22-26）的媒体数据的替代呈现时间。当在媒体帧（22-26）的帧分组（20）的中间位置调谐到流（1）时，备选时间戳（50）可用于提供有效的媒体呈现，从而缺少一些媒体帧分组（20）的帧（22,24）。

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： A method of operating a Reliable Transmission Protocol switch node to provide an IPTV multicast. IP packets transporting an encrypted media stream are received from an IPTV Head-end. The media stream contains complete image frames. Unencrypted identifiers identifying packets containing complete image frame data are also received. The received packets are stored in a buffer, and on receipt of a request from a media renderer to provide the IPTV multicast, the packet(s) containing the last complete image frame in the media stream and all subsequent packets are sent to the media renderer.

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： A test sequence (1) comprises multiple pictures (20, 22, 24, 26) comprising at least one respective intra pixel block (30, 32, 34, 36) at a respective dedicated pixel position in the pictures (20, 22, 24, 26). Such a position in a first picture (20) is different from the position of the intra block (32) in a second picture (22) of the sequence. The sequence (1) is transmitted to a user terminal (200) where it is employed for testing the quality of the data communication. By rendering the pictures (20, 22, 24, 26) packet losses are identifiable as missing pixel blocks (30, 332, 34, 36) in the media presentation (60).

摘要： A technique that permits an earlier start of the decoding and play out of media frames received via a point-to-multipoint transmission is described. The media frames comprise frames of a first type that cannot be decoded without knowledge of supplemental information and frames of a second type that include the supplemental information. According to a method aspect of this technique, frames of the first type are received and immediately buffered without waiting for reception of a frame of the second type. In a next step, a request message requesting supplemental information required for a decoding of the buffered frames of the first type is sent. Upon receipt of the requested supplemental information, the buffered frames are decoded based on the received supplemental information.

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.
