Abstract: A method for re-transmitting missing packets in an improved manner in association with transmitting an MPEG transport stream between a client and a server of a communication network is provided. New type of customized control packets are introduced which are periodically embedded into the transport stream at the server from which the MPEG transport stream is distributed, wherein each of the embedded control packets is provided with package identification data. A client receiving the MPEG transport stream, including the embedded customized control packets, will, on the basis of the package identification data obtained from a customized control packet be able to identify each of n packets which were inserted by the server into the transport stream subsequent to the respective customized control packet.

Abstract: 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.

Abstract: A multimedia provider (100) multicasts a main multimedia stream (10) comprising a mixture of intra (12) and inter frames (14, 16, 18) and multicasts an associated auxiliary stream (20) comprising intra frames (22, 24). At least a portion of the intra frames (24) in the auxiliary stream (20) are generated based on same multimedia data as at least a portion of the inter frames (14) of the main stream (10). The provider (100) also transmits a stream information channel (30) comprising information (32, 34) descriptive of time instances of intra frames (12; 22, 24) in the main (10) and auxiliary (20) streams. This information (32, 34) allows a set top box (200) to selectively connect, in connection with session set-up and channel switch, to the main (10) or auxiliary (20) stream to receive an intra frame (12; 22, 24) with as a low delay as possible.

Abstract translation: 多媒体提供商（100）多播包括帧内（12）和帧间（14,16,18）的混合的主多媒体流（10），并且多播包括帧内（22,24）的相关辅助流（20）。 基于与主流（10）的帧间（14）的至少一部分相同的多媒体数据来生成辅助流（20）中的帧内（24）的至少一部分。 提供者（100）还发送包括在主（10）和辅助（20）流中描述帧内（12; 22,24）的时间实例的信息（32,34）的流信息信道（30）。 该信息（32,34）允许机顶盒（200）与会话建立和信道切换有选择地连接到主（10）或辅助（20）流以接收帧内（12; 22,24）尽可能低的延迟。
