Embodiment Construction

[0025] Below, refer to the attached Figure 1~6 The device and method for detecting unicast channel code stream interruption of the present invention will be described in detail.

[0026] The core idea of ​​the present invention is: through the media forwarding detection unit MDU on the node, constantly monitor the code flow condition in the IPTV network, and report the abnormal situation to the CPU control module, and the channel process of the CPU control module receives the notification reported by the media forwarding detection unit After the message, if the notification message is that the channel code stream is interrupted, the channel process of the CPU control module will migrate the state of the channel code stream (see Figure 4 ), and the channel code stream is switched to the code stream source set when creating the channel, wherein the code stream source can be a local video on demand (Video on Demand, VOD) file, or other channel live broadcast sources; at the sam...

Abstract

The invention provides a device for detecting the interruption of a unicast channel code stream and a method thereof, wherein the method comprises the following steps of: step A: forwarding a media massage and regularly scanning the channel code stream of a node veneer by a media forwarding detecting unit (MDU) on a node veneer so as to determine whether the channel code stream is interrupted, ifso, reporting code stream interrupting alarm information to a CPU control module by an internal media message interactive unit (MSU); and step B: transferring corresponding channel code stream state according to the code stream interrupting alarm information, and switching channel live broadcast source by the CPU control module. The device and the method can solve the problem of the interruption of unicast channel code stream in an IPTV network.

Description

technical field [0001] The invention relates to the field of IPTV multimedia, in particular to a device and method for detecting unicast channel code stream interruption. Background technique [0002] Interactive Internet TV (IPTV) is a new interactive media video method, which is developed based on IP network. It brings users a new video experience and completely subverts the traditional TV viewing mode. For users, users can enjoy media resources according to their preferences. [0003] At present, in the IPTV system networking, there are mainly three methods, which are network-wide multicast, network-wide unicast, and unicast plus multicast; in various networking, it is mainly composed of central nodes, regional central nodes, It is composed of edge nodes, multicast switches, bearer networks, set-top boxes and other equipment; in different networking methods, the flow direction of the channel (CHANNEL) has its own characteristics. Among them, in the unicast mode of the w...
