Anti-tampering method of IPTV multicast contents

Abstract

The invention discloses an anti-tampering method of IPTV multicast contents. On a live broadcast source end, a TS multiplexer is modified, and an anti-tampering generation module is added; when a TS multiplexing module detects that the PES is carried as an I frame, the anti-tampering generation module is called to transmit the PES and to package the obtained anti-tampering information in a TS transmission stream; and on a terminal side, a TS demultiplexer is modified, and an anti-tampering verification module is added; and a TS demultiplexing module detects the PES of the I frame and the corresponding anti-tampering in real time and calls the anti-tampering verification module to complete anti-tampering verification. By adoption of the anti-tampering method disclosed by the invention, theanti-tampering security of the IPTV multicast content is improved, no dependence is made on the hardware, and the transformation of the existing system is small.

Description

technical field [0001] The invention belongs to the technical field of IPTV network television, and in particular relates to an IPTV multicast content anti-tampering method. Background technique [0002] Traditional IPTV uses a dedicated network to transmit multicast video, which not only improves broadcast stability, but also improves broadcast security. However, with the in-depth transformation of IPTV OTT, the increasing demand for IPTV public network access, and the continuous advancement of public network multicasting, the security boundary between private networks and public networks is constantly being broken, and network attacks and content tampering from the public network And other network attacks continue to threaten the broadcast security of IPTV. [0003] The anti-tampering technology of IPTV multicast content is an important means to prevent the risk of safe broadcast of IPTV multicast video. At present, there are two main implementation ideas: [0004] (1) V...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the problem that the existing IPTV multicast content anti-tampering method is difficult to meet the requirements of IPTV safe broadcasting, the present invention proposes a new IPTV multicast content anti-tampering method; the present invention improves the security of IPTV multicast content anti-tampering, And it does not depend on the hardware, and the modification of the existing system is small
