Problems solved by technology

IPTV service content security issues include: the video content on the user side is truncated, inserted, replaced, and EPG content is modified, etc.
The problems with this method are: 1) It is difficult to synchronize the content of the source and the user
2) The calculation of video decoding and image comparison is very large, which cannot meet the application occasions of real-time comparison
3) It is necessary to establish an image fingerprint label library in the service test, and the workload of label verification is heavy
The problem that this method exists is: 1) the synchronicity problem of source end and user end stream media segmentation
2) It is necessary to establish an MD5 tag library in the service test, and the workload of tag verification is very large
[0006] 3. DRM copyright protection can only protect copyrighted videos from being violated, but it cannot guarantee that ordinary video content will not be tampered with or replaced

Embodiment Construction

[0032] The present invention will be further described below in conjunction with accompanying drawing.

[0033] The encapsulation of IPTV video stream is divided into ES stream, PES stream and TS stream. The ES stream (Elementary Stream) is composed of three parts, which are the image data stream encoded by the MPEG-2 video encoder, the audio data stream encoded by the MPEG-2 video encoder, and other encoded data streams. PES stream (Packetized Elementary Streams) is the data stream formed after the ES stream is processed by the PES packer. In this process, operations such as ES stream grouping, packaging, and adding header information are completed. Usually, a complete frame of I, P, and B is a frame. PES pack. The TS stream is composed of fixed-length TS packets (188 bytes). The TS packet is a repackage of the PES packet. The header information of the PES packet still exists in the TS packet. The relationship between ES stream, PES stream and TS stream is as follows: fig...

Abstract

The invention discloses a method for guaranteeing IPTV content safe broadcasting, which comprises the following steps: a platform side signs TS stream content; the user side audits the content signature of the TS stream. The present invention is based on the MPEG used in digital television and IPTV-2 standard TS encapsulation format, based on this encapsulation format, video content signature is added to distinguish the legitimacy of video content. It can complete the legitimacy monitoring at one end without interacting with the server, and can judge the legitimacy of the content at the user side. But also has high efficiency, low computational load and low retrofit load to the existing system.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for ensuring safe broadcasting of IPTV (Interactive Network Television) content. Background technique [0002] As a three-network integration service, IPTV should ensure the safety of broadcast content and transmission according to the requirements of the State Administration of Radio, Film and Television, so as to realize the controllability and management of content. With the large-scale development of IPTV services, content security has drawn more and more attention from relevant government departments. IPTV service content security issues include: video content on the user side is truncated, inserted, replaced, EPG content is modified, etc. [0003] At present, the main means to ensure the security of IPTV business content are: to strengthen the security of the end-to-end platform, terminal and network of IPTV business; to monitor the legality of the video con...
