摘要： The invention teaches a media container file (1) comprising media data organized into media source blocks (20; 22; 24). The media source blocks (20; 22; 24) are partitioned into source symbols that can be processed by a forward error correction (FEC) algorithm for generation of FEC redundancy data (70). Information (30; 32; 34) of this source block partitioning is included in the file (1) in addition to the source blocks (20; 22; 24). The container file (1) also comprises meta data (40) providing an association between the media source blocks (20; 22; 24) and the partitioning information (30; 32; 34). The container file (1) can be employed by a media server (200) in a media session for compiling media data packets to be transmitted to requesting clients (400; 410; 420) without the need of extensive data processing before calculating FEC data.

摘要： The invention teaches a media container file (1) comprising media data organized into media source blocks (20; 22; 24). Forward error correction (FEC) redundancy data is pre-calculated for the different source blocks (20; 22; 24) and organized into the container file (1) as different FEC reservoirs (30; 32; 34). The container file (1) also comprises meta data (40; 45) providing an association between the media source blocks (20; 22; 24) and the respective FEC reservoirs (30; 32; 34). The container file (1) can be employed by a media server (200) in a media session for compiling media data packets to be transmitted to requesting clients (400; 410; 420) without the need of extensive data processing and FEC calculation.

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 basic idea for efficient media communication between two nodes in a group communication system is to set up a number, N, of parallel, separate media streams of the same media type in a given direction between the nodes, where N is equal to or greater than 2. Before setting up the media streams, the actual number of media streams is negotiated (Sl). Once the negotiation is completed, the media streams are established (S2). Media data of the same type can then be transferred in parallel, media streams (S3), where each media stream may include media data from a separate source or from a mix of sources. In this way, a richer and/or more personalized rendering of the media data is enabled since media data may be transported as individual media streams and processed locally in a participant, rather than processed and mixed into a single stream by a central mixer.
摘要翻译：在组通信系统中的两个节点之间的有效媒体通信的基本思想是在节点之间的给定方向上建立数个N个相同媒体类型的并行分离的媒体流，其中N等于或大于在设置媒体流之前，协商媒体流的实际数量（S1）。一旦协商完成，就建立媒体流（S2）。然后可以并行地传送相同类型的媒体数据，媒体流（S3），其中每个媒体流可以包括来自单独来源的媒体数据或源的混合。以这种方式，媒体数据的更加丰富和/或更个性化的呈现是可以实现的，因为媒体数据可以作为单独的媒体流传送并在参与者中本地处理，而不是通过中央混合器被处理并混合成单个流。

摘要： A technique is disclosed for controlling data packet transmissions from a server (205) via a network buffer (230) to a client (215) having a client buffer (240). The technique determines the network buffer fill level and the client buffer fill level. If the transmission of a next packet would cause the network buffer (230) fill level to exceed a first threshold and/or the client buffer (240) to exceed a second threshold, then the transmission is delayed until both conditions are satisfied.
摘要翻译：公开了一种用于控制从服务器（205）经由网络缓冲器（230）到具有客户端缓冲器（240）的客户端（215）的数据分组传输的技术。该技术确定网络缓冲区填充级别和客户端缓冲区填充级别。如果下一个分组的传输将导致网络缓冲器（230）填充级别超过第一阈值和/或客户机缓冲器（240）超过第二阈值，则传输被延迟直到两个条件都被满足。

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).
