IP network video business remote collection and control device

Abstract

The present invention discloses an IP network video business remote collection and control device. The device is connected with a set top box and a monitoring center, and comprises an audio signal collection module, a video signal collection module, an audio and video coding module, a streaming media service module, a business quality KQI (Key Quality Indicators) index calculation module, a network data collection module, a network quality KPI (Key Performance Indicator) calculation module and a data communication module. The audio signal collection module and the video signal collection module are configured to collect audio and video signals from the set top box; the audio and video coding module is configured to perform digitization coding of audio and video signals; the streaming media service module is configured to supply streaming media service for the monitoring center; the business quality KQI index calculation module is configured to calculate and obtain audio and video quality KQI indexes; the network data collection module collects network IP data flow flowing through the set top box; and the network quality KPI calculation module calculates network KPI quality indexes. The collection and the returning of the audio and video signals, business quality KQI and network quality KPI are realized.

Description

technical field [0001] The invention relates to the technical field of communication. Background technique [0002] Currently, telecom IPTV (Interactive Internet Television) and Internet OTT (abbreviation for Over The Top, which refers to providing users with various application services through the Internet) video services are developing rapidly. However, compared with traditional broadcast digital TV, the quality of IPTV and OTT services carried on a best-effort IP (interconnection protocol between networks) network is indeed difficult to guarantee. Therefore, in order to ensure the service quality of various places, IPTV and OTT service operators need to monitor the quality of multiple service access points in real time. The existing technology generally adopts the following methods: [0003] 1. Directly transmit audio and video streams back to the monitoring center. [0004] The original audio and video stream of the monitoring point is transmitted back to the monitori...

AI Technical Summary

Problems solved by technology

This method has the following limitations: 1) A dedicated network backhaul is required, which increases resource investment, and some areas do not have the conditions for backhaul networks; 2) The quality of the backhaul network (packet loss and delay, etc.) Interfering with the judgment of the service quality of the monitoring point; 3) The control of the program is more complicated

This method has the following limitations: 1) Visual monitoring cannot be achieved in the monitoring center, and the quality index cannot completely replace the effect of human viewing; 2) The function of program content safety supervision cannot be realized, and operators are obliged to supervise transmission in the network Whether the video content of the video has been illegally replaced; 3) The manipulation of the program is more complicated
