Abstract: A system for processing a streaming media service and a method and a network device thereof are provided. The system includes a network device and an encoder. The network device has an embedded streaming function module. The encoder includes two egress ports, where the two egress ports of the encoder are connected to an active input port and a standby input port of the network device respectively. The encoder is configured to: receive a streaming media service signal, encode the streaming media service signal to generate a streaming media service coded signal, and send the streaming media service coded signal to the network device. The network device is configured to receive, by using the embedded streaming function module through the active input port or the standby input port, a streaming media service coded signal sent by the encoder, and provide the streaming media service coded signal for a terminal.

Abstract: Embodiments of the present invention provide a method, an apparatus and a system for sending and receiving a media stream. In the embodiments of the present invention, during a transmission process of media content, if the packet loss occurs, and if retransmission still does not succeed after the retransmission has been attempted for finite times, the retransmission of the lost data packet is abandoned through notification of the retransmission suppression information, and transmission of a subsequent part of media stream is continued, which ensures uninterrupted transmission of the media stream, and avoids the occurrence of a screen mess of a picture, a picture jitter or pause, and even a program interrupt, thereby improving picture quality.
