    Abstract: 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.

    Abstract translation: 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。

    Abstract: 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.

    Abstract translation: 本发明教导了一种媒体容器文件（1），其包括组织在媒体源块（20; 22; 24）中的媒体数据。 媒体源块（20; 22; 24）被划分为可由用于生成FEC冗余数据（70）的前向纠错（FEC）算法处理的源符号。 除了源块（20; 22; 24）之外，该源块划分的信息（30; 32; 34）还包括在文件（1）中。 容器文件（1）还包括提供媒体源块（20; 22; 24）和分区信息（30; 32; 34）之间的关联的元数据（40）。 容器文件（1）可以由媒体会话中的媒体服务器（200）采用，用于在计算FEC数据之前不需要广泛的数据处理来编译要发送到请求客户端（400; 410; 420）的媒体数据分组。

    Abstract: 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.

    Abstract: A flexible approach to segmenting a resource (e.g., a media resource, such as a media segment, or other resource, such as a resource normally fetched or pushed using general file transfer protocols like HTTP) into a plurality of fragments. By employing such an approach, the delay until the resource can be utilized at the client side is reduced. Certain embodiments are provided which apply the flexible segmentation approach to ISOBMFF media segments for video streaming, such as would be used with Live DASH streaming.
