Embodiment Construction

[0024] The method for IPTV system monitoring video quality comprises the following steps:

[0025] Step 1, the multicast source server creates a channel for testing IPTV, and sends a fixed-format IP multicast test packet with a specific multicast MAC address, where each IP multicast test packet contains a sequence number, and two adjacent The serial number of the packet is incremented, and the size and rate of the IP multicast test stream are controlled by configuring the multicast source server;

[0026] Step 2, DSLAM joins the test channel by sending the multicast join message JOIN, and no longer sends the leave message LEAVE, that is, keeps joining the test channel. After joining the IPTV test channel, the DLSAM hardware can test the specific multicast stream according to the IP multicast The MAC address extracts the IP multicast test packet from the received traffic, and parses out the serial number of the packet, and judges whether the serial number of the received IP mul...

Abstract

The invention discloses a method for monitoring the video quality of an internet protocol (IP) television, which comprises: step 1, a multicast source server establishes a multicast test channel and sends an IP multicast test stream, wherein the IP multicast test stream has an IP multicast test pack containing sequence number, the sequence numbers of the adjacent test packs being increased progressively; step 2, a digital subscriber line access multiplexer is added into the multicast test channel to receive the IP multicast test stream, and inspects the video quality of IP television according to the continuity of sequence number of the IP multicast test pack, and sends the test result to a service management system; step 3, the service management system receipts and then processes the test result and displays the video quality of IP television. Therefore, the video quality of IP television can be monitored regardless of user data stream.

Description

technical field [0001] The invention relates to the field of IPTV, in particular to a method and system for monitoring the video quality of the IPTV. Background technique [0002] As global operators pay more and more attention to IPTV, the global IPTV market shows a momentum of accelerated growth. Since IPTV is a triple play service that integrates data, voice and video, unprecedented requirements are placed on service quality. In addition to requiring DSLAM (Digital Subscriber Line Access Multiplexer) to support multicast, bandwidth, QoS and multi-service capabilities in the broadband access network, DSLAM is also required to have an effective IPTV quality monitoring system and fault location means, and timely Discover potential congestion, blocking, conflicts and other faults in the IP network, and realize real-time monitoring and active operation and maintenance of services. [0003] In the prior art, it is finally found that the video quality of the Internet TV has de...
