摘要： 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.
摘要翻译：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。

摘要： 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.

摘要： A method, system, device, and computer code product is disclosed in which a sender (10) transmits data to a plurality of receivers (20) via a point-to-multipoint session. The receiver sends data repair requests to the sender (10) requesting data expected but not received and the sender (10) retransmits the expected but not received data via the point-to-multipoint session. The sender (10) can also schedule point-to-point data repair sessions with individual receivers if the retransmission via the point-to-multipoint session does not correct all errors. The sender (10) can be configured to delay point-to-point repair sessions using a randomization mechanism based on the number of receivers using the point-to-multipoint session.

摘要： The invention relates to signalling in broadcast and multicast environments. For a service in the broadcast is defined an indicator, which is formulated into a unique indicator. The indicator is mapped into one time-slot in a signalling channel. A notification relating to the service is transmitted during the said time-slot. The notification is used for enabling the receiver for receiving said service, wherein the receiver may be turned off at other times.
