    Abstract: A compression context for a plurality of packets is established with a receiving device. Each of these packets is associated with one or more reliable multicast protocols, such as the Layered Coding Transform (LCT) protocol, the Asynchronous Layered Coding (ALC) protocol, the FLUTE protocol, the MUPPET protocol, and the NACK-Oriented Reliable Multicast (NORM) protocol. Upon establishment of the compression context, a compressed packet is generated for one of the plurality of packets and transmitted to the receiving device. The compressed packet has a reduced number of bits in its header. Upon receipt, the receiving device decompresses the compressed packet based on the compression context.

    Abstract translation: 用接收设备建立多个分组的压缩上下文。 这些分组中的每一个与一个或多个可靠的多播协议相关联，例如分层编码变换（LCT）协议，异步分层编码（ALC）协议，FLUTE协议，MUPPET协议和面向NACK的可靠多播（ NORM）协议。 在建立压缩上下文时，为多个分组之一生成压缩分组，并发送给接收设备。 压缩包在其头部中具有减少的比特数。 在接收到接收设备时，基于压缩上下文来解压缩压缩的分组。

    Abstract: Methods and systems are provided for filtering digital data formatted in packets. A filter module contains a plurality of filters and is coupled to a filter mapping module. The filter mapping module receives the identification of clusters of discrete segments of a packet and selects a group of fixed length filters to filter the clusters.

    Abstract: A broadcaster prepares primary content session stream data, and auxiliary content files, such as subtitle text. The auxiliary data may be provided using a two-level structure. Here, the first level can be is a file having plural entries each with a control information item, e.g. a timestamp, and a reference is found. A receiver at a time relating to a timestamp renders video content from a packet (43) having that timestamp, and also renders subtitle text from the second level file (46) having the same reference as the reference corresponding to the timestamp in the first level file. Thus, the broadcaster defines when subtitle text strings are to be rendered but without requiring streaming of packets including the auxiliary data. This makes it easy for a receiver to synchronise the auxiliary data with the primary content. A single level file structure can be used instead.

    Abstract translation: 广播公司准备主要内容会话流数据和辅助内容文件，如字幕文本。 可以使用两级结构来提供辅助数据。 这里，第一级可以是具有多个条目的文件，每个条目具有控制信息项，例如。 时间戳和参考。 与时间戳有关的接收器从具有该时间戳的分组（43）呈现视频内容，并且还使来自第二级文件（46）的字幕文本具有与对应于第一级中的时间戳的引用相同的引用 文件。 因此，广播机构定义字幕文本字符串何时被呈现，而不需要包括辅助数据的分组流。 这使得接收机容易地将辅助数据与主要内容同步。 可以使用单级文件结构。

    Abstract: For the notification of a receiving device about a forthcoming transmission session, an identifier of one of various possible types of identifiers in a transmission session is mapped to a transmission session identifier field. This field is used for notifying the receiving device. Further, a repetition value is added to the transmission session identifier field, which indicates whether the forthcoming transmission session is new or not. Further, the receiving device may release context data stored for a particular transmission session identifier, if an acquisition of data in transmission sessions identified by the transmission session identifier can be terminated.
