Method and system for safe broadcasting of live broadcast signals

Abstract

The invention discloses a method and system for securely playing live broadcast signals. The method comprises the following steps: a terminal player engine obtains a playing address of a live broadcast signal system and gasket address information of a gasket management system; the terminal player engine sends a playing request of a gasket proxy forwarding module, and the gasket proxy forwarding module starts a video signal playing proxy and sets gasket information; the gasket proxy forwarding module downloads gasket content information from the gasket management system into a cache of the terminal player engine in an asynchronous downloading manner; the gasket proxy forwarding module obtains a live broadcast signal from the live broadcast signal system and forwards the live broadcast signal to the terminal player engine; and the gasket proxy forwarding module sets a gasket stimulation time threshold, automatically plays a gasket video signal after the interruption of the live broadcast signal exceeds the gasket stimulation time threshold and restores to play the live broadcast signal after the live broadcast signal is normal. By adoption of the method and system disclosed by the invention, the secure playing of the live broadcast signals can be realized.

Description

technical field [0001] The invention relates to the technical field of video signal processing, in particular to a method and system for safely broadcasting live signals. Background technique [0002] In the live broadcast scene of IPTV radio and TV channels, in order to ensure the user experience effect of the live broadcast signal, signal interruption is generally not allowed during the live broadcast process. If the live broadcast signal is interrupted for a long time or occurs frequently, it will affect the user's experience. At the same time, the number of viewers in the live broadcast field is extremely large, and if some important activities are interrupted in the live broadcast, it will have a relatively large negative impact. For Internet TV service providers , potentially losing a large number of users. [0003] Traditionally, in the video signal transmission process from the signal source to the terminal playback device, multiple subsystems provided by different ...

AI Technical Summary

Problems solved by technology

[0005] One is that when the video signal of the terminal video playback device is interrupted, the video playback request needs to be resent, and the source side needs to send the backup video signal to the terminal video playback device, causing the signal delay time to be too long;

[0006] Second, if the video signal transmission fails due to link interruption, the backup signal device cannot be activated;

[0007] The third is that the construction cost is too high, and it cannot be guaranteed that all channels can be guaranteed;

[0008] Fourth, for multiple users at the same time, the source end may receive information from multiple video playback terminals at the same time, and resend video playback request information, resulting in heavy processing pressure on the server at the source end
