摘要： The present invention discloses a method for reducing the interruption time of internet protocol television (IPTV) multicast streams, which comprises: after the home access gateway core resets, it is detected whether the network port connecting to the access device side is started; when started, an internet group management protocol (IGMP) query command is sent to access devices through the network port; on the basis of the identification information of the access devices which answer the IGMP query command, a multicast forwarding table from the home access gateway to the access devices is built and is reported to the IGMP multicast source. A device implementing the method is also disclosed by the invention. The invention can reduce the interruption time of IPTV multicast streams and improve the quality of service (QoS) of IPTV system, and is easily implemented.

摘要： A video encoding device ( e.g ., a wireless transmit/receive unit (WTRU)) may transmit an encoded frame with a frame sequence number using a transmission protocol. The video encoding device, an application on the video encoding device, and/or a protocol layer on the encoding device may detect a packet loss by receiving an error notification. The packet loss may be detected at the MAC layer. The packet loss may be signaled using spoofed packets, such as a spoofed NACK packet, a spoofed XR packet or a spoofed ACK packet. A lost packet may be retransmitted at the MAC layer ( e.g ., by the encoding device or another device on the wireless path). Packet loss detection may be performed in uplink operations and/or downlink operations, and/or may be performed in video gaming applications via the cloud. The video encoding device may generate and send a second encoded frame based on the error notification.

摘要： For a media on demand (MoD) session where content is streaming from a first content server to a media agent, a server manager operates to minimize or eliminate the impact of a failure affecting the streamed content. The server manager will monitor at least the first content server, and when a failure is detected, initiate the transition from the first content server to a second content server. In particular, the server manager will directly or indirectly ensure that the media agent has sufficient information to establish another streaming session for the MoD session with the second content server. The transition is preferably facilitated in real time and within a short enough time period to eliminate or at least minimize the effect of the media ultimate presentation to the subscriber.
摘要翻译：对于内容从第一内容服务器流式传输到媒体代理的媒体点播（MoD）会话，服务器管理器操作以最小化或消除影响流传输的内容的影响。服务器管理器将至少监视第一内容服务器，并且当检测到故障时，启动从第一内容服务器到第二内容服务器的转换。特别地，服务器管理器将直接或间接地确保媒体代理具有足够的信息以建立与第二内容服务器的MoD会话的另一流传输会话。该转换优选地实时地和在足够短的时间段内被有助于消除或至少最小化媒体对用户的最终呈现的影响。
