Quality assurance (QA) system and method of internet protocol television (IPTV) services

Abstract

The invention relates to a quality assurance (QA) system of internet protocol television (IPTV) services, comprising a management server which is arranged at the head end of an IPTV system and subjective quality estimation devices which are arranged at each IPTV terminal respectively, wherein the management server is connected with the subjective quality estimation devices by IPTV system networks, and the subjective quality estimation devices are integrated into a service quality measurement and control module in a set top box (STB) of each IPTV terminal. The invention also relates to a QA method of IPTV services by using the system. In the method, the service quality measurement and control module is used for measuring and controlling the service quality of a video which is played by the STB of the IPTV terminal so as to acquire the subjective quality score; and the subjective quality score is compared with a threshold, and if the subjective quality score is lower than the threshold, an alarm is sent out, thus realizing subjective quality estimation for the client of the IPTV system, and perfecting the quality detection modes of the IPTV services. The system provided by the invention is simple in structure, and the method provided by the invention is low in operating cost and easy and convenient in application modes.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to the field of Internet TV technology, and specifically refers to an IPTV service quality assurance system and a quality assurance method. Background technique [0002] Because IPTV is a TV-like media service, users expect to get the same level of service as cable TV, including channel switching speed, program image quality, and smooth playback. The traditional broadband service quality monitoring focuses on the monitoring of the data link layer and the network layer, which cannot directly reflect the subjective experience of users on IPTV services, so it cannot meet the needs of IPTV quality monitoring. [0003] For traditional telecommunication services, quality of service (QoS) usually refers to network performance, especially network transmission performance. Since IPTV is an upper-layer application service based on ordinary telecommunication services, traditional QoS...

AI Technical Summary

Problems solved by technology

[0005] At present, the monitoring method commonly used in IPTV services is to realize monitoring by adding equipment at each network node. The equipment cost of the system is relatively high, and the monitoring unit is only limited to the network node. It is impossible to configure a monitoring unit for each IPTV user terminal. Therefore, it is difficult to realize the video quality evaluation for the user's subjective experience

And for the maintenance and testing of the last mile, it still depends on the hand-held terminal to complete the door-to-door, and the maintenance cost remains high

This has formed an obstacle to the further promotion and application of IPTV
