Service quality monitoring system for intelligent television terminal

Abstract

The invention discloses a service quality monitoring system for an intelligent television terminal. The system mainly comprises a service quality monitoring module, a service quality analysis module and a service monitoring control module, wherein the service quality monitoring module is responsible for indistinguishably capturing all data packets passing through a network port, performing packet dropping, end-to-end time delay calculation and streaming media protocol analysis and performing service quality monitoring to realize calculation and monitoring based on a program stream; the service quality analysis module is used for collecting parameters transmitted from the other modules, analyzing and periodically reporting to a server of a business trader; the weight monitoring control module is responsible for receiving a signal from the control server to adjust a monitoring strategy, for example changing of a report period, a statistical cycle, an ftp (File Transfer Protocol) server address and the like. The system has real-time property and is low in consumption of a CPU (Central Processing Unit) and a memory, and the acquired service quality parameters are much closer to the actual effect of play.

Description

technical field [0001] The invention relates to the technical field of video-on-demand, in particular to a service quality monitoring system for smart TV terminals. Background technique [0002] With the rapid development of China's digital TV industry, cable digital TV users continue to maintain substantial growth, two-way transformation and network integration are advancing rapidly, and value-added services based on cable networks have also been widely used; The development of TV (International Protocol Television, IPTV) users, and the increase in bandwidth have also promoted the growth of the number of users. With the vigorous promotion of operators such as radio, television and telecommunications, the coverage of digital TV, interactive network TV and other services is becoming wider and wider, which also puts forward higher requirements for the service quality of the network. [0003] Currently, discrete quality of service (QoS) assessments such as packet loss and dela...

Problems solved by technology

QoE is measured based on user experience, mainly using subjective evaluation method, that is, using viewers to subjectively score image quality. Replaced by the no-reference objective evaluation method with better real-time performance

Objective evaluation is a single-ended evaluation method that integrates soft probes for quality monitoring into receiver test equipment and collects relevant parameters for analysis. However, this method generally requires complex calculations and is difficult to integrate into weak smart TVs. terminal

At the same time, set-top boxes or smart TVs are used as the carrier of video services, and the performance of memory and CPU is far inferior to that of PCs. As a result, existing PC packet capture software cannot directly run on set-top boxes.
