Embodiment Construction

[0017] The specific implementation of the method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] in such as figure 1 In the shown structural diagram of the TV program encryption system on demand, the encryption system of the present invention includes:

[0019] Ethernet switch A, mainly completes the duplication of one live stream into two;

[0020] Streaming server B completes the recording of channel programs, receives encrypted programs released by the content management server, and provides users with on-demand services;

[0021] On-demand program pre-encryption server C is a server that completes on-demand program pre-encryption;

[0022] Content management server (CMS, content manager system) E, manages content such as programs and channels, such as recording / release control of on-demand TV programs;

[0023] The live encryption server D is a server that encrypts live streams, completes the encryption ...

Abstract

The invention relates to the field of web television and discloses a TV-on-Demand encryption method, the following is in detail: an IPTV system network ensures that unencrypted live broadcast current is divided into two parts, one part is directly provided to users as TV on-Demand through live broadcast encryption server, and the other part is sent to demanding pre-encryption server and encrypted after recorded by current media server. With encryption finished, the demanding pre-encryption server automatically pushes the programs to the current media server. With the programs recorded and encrypted, a content management system automatically publishes the programs for the demanding of users. The invention resolves the encryption problem of TV on-Demand, thus providing convenience for content providers to offer safe and reliable programs.

Description

technical field [0001] The invention relates to the field of network television, in particular to an encryption method adopted for protecting the safety of program content when developing on-demand television services. Background technique [0002] Internet TV business (ie IPTV business) has developed rapidly at home and abroad, and has gradually become one of the killer services for fixed network operators to increase average revenue per user (ARPU-Average Revenue Per User). Through the IPTV platform, ordinary users can perform video-on-demand, or watch real-time live TV programs, etc. [0003] Video-on-demand is a basic service form of Internet TV services. Users can select audio and video files to play according to their needs. It is a point-to-point play. It has completely subverted the user's viewing habits, changed from passive viewing to active on-demand, and gave the user the right to choose the content to be played, which greatly satisfied the individual needs of u...
