Embodiment Construction

[0035] The core idea of ​​the present invention is: the edge node notifies the central node that it supports forward error correction (FEC) capability, and receives the description reply message carrying the configuration information of the relay channel sent by the central node, and the configuration information includes FEC compensation parameter information; After successfully applying to the central node for the resource allocation of the relay channel, obtain the source code stream and the FEC compensation code stream sent from the central node; perform FEC compensation processing on the source code stream according to the configuration information and the FEC compensation code stream, and obtain the compensation processing The source code stream of the relay channel greatly increases the fluency of the media screen after compensation, and the impact of packet loss is not felt visually, which improves the reliability of media transmission in IPTV and improves the quality of...

Abstract

The invention provides a method, a device and a system for establishing the packet loss compensation in a relay channel, belonging to the field of interactive internet protocol television (IPTV). The method comprises the following steps: sending description request information to a central node by an edge node, wherein, the description request information comprises information of the forward error correction (FEC) capability supported by the edge node; receiving the description responsive information which is sent by the central node and carries the relay channel configuration information, wherein, the configuration information comprises FEC compensation parameter information; acquiring a source code stream and an FEC compensation code stream which are sent by the central node after succeeding in applying to the central node for the distributive resource of the relay channel; and carrying out FEC compensation treatment on the source code stream according to the configuration information and the FEC compensation code stream to obtain the source code stream treated by compensation. The system comprises the central node and the edge node. The technical scheme provided by the invention improves the reliability of media transportation in IPTV and improves the quality of customer experience.

Description

technical field [0001] The present invention relates to the field of Internet Protocol Television (IPTV), in particular to a method, device and system for establishing packet loss compensation in relay channels. Background technique [0002] IPTV is an IP network that transmits TV, video, text, graphics and data, etc., and provides Quality of Service (QoS) / Quality of Experience (Quality of Experience, QoE) assurance, security, interactivity and reliability. Manageable multimedia services are obviously different from streaming media applications on the Internet that are uncontrollable and unmanageable, and whose quality and safety are not guaranteed. [0003] The relay channel in IPTV is a channel created in order to relieve the pressure on the central node and improve the efficiency of network utilization when the IPTV network load is unbalanced. Specifically, the edge node "pretends" to be a set-top box to request the code stream from the central node, and the edge node fo...
