Problems solved by technology

Using the packet loss recovery method may affect the sensitivity of the user side to the packet loss rate. If the packet loss rate is still used for fault detection in the scenario where the packet loss recovery method is used, the detection result will be inaccurate.

Embodiment Construction

[0154] The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention.

[0155] Such asfigure 1 As shown, the IPTV video service is provided by the operator with the head end equipment (head end, HE) and the user terminal, wherein, the HE provides the IPTV video source, encodes the video source into a video stream, and then divides the video stream into multiple source The data packet, the source data packet is transmitted to the user terminal through the content distribution network (content delivery network, CDN), broadband remote access server (broadband remote access server, BARS) and other network equipment, such as: set top box (set top box) , STB), and then transmitted by the set-top box to a display device (such as: a TV) for display. During the process of transmitting the video stream from the head-end device to the first network device, the video stream c...

Abstract

An embodiment of the invention provides a fault detection method, a monitoring device and a network device, relating to the technical field of multimedia, and being able to perform fault detection ona video service accurately. The fault detection method comprises the steps of: acquiring a video quality parameter of monitored video streams, wherein the video quality parameter is determined according to a packet loss recovery method of the monitored video streams, the video quality parameter comprises a valid packet loss factor, the valid packet loss factor is used for indicating the validity of the packet loss recovery method of the monitored video streams in recovering lost network packets; and performing fault detection according to the video quality parameter of the monitored video streams.

Description

technical field [0001] The embodiment of the present invention relates to the field of multimedia technology, and in particular to a fault detection method, monitoring equipment and network equipment. Background technique [0002] In the Internet Protocol television (IPTV) video service, the video headend sends the video stream, which is transmitted by the network equipment to the set top box (STB) deployed on the user side, and the STB transmits the video stream to the display device for display. . Packet loss and delay during network transmission will have varying degrees of impact on video services. Usually, the packet loss rate can be used to represent the impact of network transmission quality on video quality. In addition, in the prior art, the monitoring of the network transmission quality is realized through the packet loss rate. When the video service fails (for example, blurred screen occurs during playback), once the packet loss rate is determined to be higher t...
