Method and system for realizing IPTV video monitoring service based on peer technology

Abstract

The invention provides a method for implementing an IPTV video monitoring service by using peer-to-peer (P2P) technique. The method comprises: a terminal device receives a video plan and sends the plan to an IPTV service management system; the IPTV service management system receives and stores the video plan; an execution decision algorithm selects one or more terminal device on the network and then notifies the terminal device to store the video based on the video plan, and records the information of the terminal device; the terminal device receives the notification and then stores the videobased on the video plan; when the terminal device monitors or plays back the video in real time, if the video is not stored on the terminal device that sends the video plan, the IPTV service management system will coordinate or directly establish the link with the terminal device that stores the video; and the terminal device that stores the video downloads the video content or transmits to the terminal device that sends the transfer request by means of real-time streaming media, and the terminal device that sends the transfer request performs the real-time monitoring or playback after reception.

Description

technical field [0001] The present invention relates to a communication network based on P2P (peer-to-peer technology), in particular to a communication network of an IPTV (Internet Network Television) video monitoring service system using P2P. Background technique [0002] However, existing video surveillance service systems are all designed based on a dedicated platform, for example, the video surveillance service system of Beijing Mutual Trust and Intercommunication. The dedicated system is generally composed of the monitoring head-end PU, video encoder, PTZ controller and terminal equipment CU. The monitoring head-end PU is responsible for video recording and storage, the video encoder is responsible for converting the video format into standard formats such as H.264 and MPEG4, the pan / tilt control is responsible for zooming, rotating and stretching the lens, and the terminal is responsible for displaying the video. Generally, the head-end PU records and stores the vide...

AI Technical Summary

Problems solved by technology

[0004] 1) Due to the limited storage space of the head-end PU or the local server, the number of parallel recordings and the storage space of the system are limited

[0005] 2) The expansion of video surveillance services, such as home surveillance services, is limited

[0006] 3) The types of terminal devices supported are limited, for example, mobile phones, set-top boxes, etc. cannot be supported

[0007] 4) Since the head-end PU is installed on site, it is prone to failure

However, if there are too many parallel recordings at the same time or the user does not have enough storage space on the edge POP point, the recording service will also be denied

Adding an expensive streaming media server will greatly increase the construction cost of the video surveillance business system
