Abstract
The invention discloses a kind of encryption systems based on flv formatted file comprising data module, for storing data information；Audio data block, for storing audio-frequency information；Video data module, for storing video information；Script data module, for storing the information of flv；Encrypting module, for doing a fractionation for flv video file, and each section of flv file is individually Resealed and encrypted according to flv encapsulation format；Media file definition module is flv for defining original file format, and file format is pcf after encryption, and Encryption Algorithm is referred to as DRM etc..The present invention encrypts flv original video file, and encrypted pcf file format and flv format are no longer identical, therefore player can not directly play encrypted pcf file, has achieved the purpose that protect former piece, has prevented video from maliciously being cracked, damage user benefit.
Description
Technical field
The present invention relates to a kind of encryption systems of file, more particularly to a kind of encryption system based on flv formatted file.
Background technique
Flv stream media format is a kind of new video format, and full name is Flash Video.It is efficiently solved
After video file imports Flash (animation software), to make derived SWF (shock wave flash's, Flash is dedicated
Format) file size is huge, and it cannot be the disadvantages of being used well on network.Present mainstream player, has all supported flv
The broadcasting of formatted file, since flv format video itself has the characteristics that low, small in size, the suitable network transmission of occupation rate, so that
Its mainstream for becoming field of video online playing.
Traditional internet video cloud playing platform, general direct request server download flv file, and player carries out again
It plays.
It is traditional directly download played out after flv video file again this scheme have the shortcomings that it is very big: the flv of downloading
File is not encrypted, and substantially any player can arbitrarily play video in different platform, not can guarantee the interests of user.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of encryption systems based on flv formatted file, to flv original
Video file is encrypted, and encrypted pcf file format and flv format are no longer identical, therefore player can not directly be broadcast
Encrypted pcf file is put, has achieved the purpose that protect former piece, has prevented video from maliciously being cracked, damage user benefit.
The present invention is to solve above-mentioned technical problem by following technical proposals: a kind of adding based on flv formatted file
Close system comprising:
Data module, including audio data block, video data module, script data module, for storing data information；
Audio data block, for storing audio-frequency information；
Video data module, for storing video information；
Script data module, for storing the information of flv；
Encrypting module, including media file definition module, DRM module are used for according to flv encapsulation format, for flv video
File does a fractionation, and each section of flv file is individually Resealed and encrypted；
Media file definition module is flv for defining original file format, and file format is pcf after encryption, and encryption is calculated
Method is referred to as DRM；
DRM module, for reinforcing protecting the copyright of digitized sound, video content；
Communication module is got off the file download encrypted by http request for following HTTP/1.1 agreement；
Online playing module, after downloading the pcf file encrypted, player is decrypted according to the algorithm of definition
It is reduced into flv file, then is directly played.
The positive effect of the present invention is that: the present invention encrypts flv original video file, encrypted pcf
File format and flv format are no longer identical, therefore player can not directly play encrypted pcf file, and it is former to have reached protection
The purpose of piece prevents video from maliciously being cracked, and damages user benefit.
Detailed description of the invention
Fig. 1 is that the present invention is based on the system framework figures of the encryption system of flv formatted file.
Specific embodiment
Present pre-ferred embodiments are provided with reference to the accompanying drawing, in order to explain the technical scheme of the invention in detail.
As shown in Figure 1, the present invention is based on the encryption systems of flv (FLASH VIDEO, stream media format) formatted file to include
Data module, encrypting module, communication module, online playing module, in which:
Data module, including audio data block, video data module, script data module, for storing data information；
Audio data block, for storing audio-frequency information；
Video data module, for storing video information；
Script data module, for storing the information of flv；
Encrypting module, including media file definition module, DRM (Digital Rights Management, digital publishing rights
Management) module, for doing a fractionation for flv video file, and to each section of flv file according to flv encapsulation format
Individually is Resealed and encrypted；
Media file definition module is flv for defining original file format, and file format is pcf after encryption, and encryption is calculated
Method is referred to as DRM；
DRM module, for reinforcing protecting the copyright of digitized sound, video content；
Communication module, for following HTTP/1.1 agreement, by http, (HyperText Transfer Protocol surpasses
Text transfer protocol) it requests to get off the file download encrypted；
Online playing module, for downloading the pcf of encryption (Personal Computer Faster, PC accelerate)
After file, player is decrypted according to the algorithm of definition can be reduced into flv file, then directly play.
Particular embodiments described above, the technical issues of to solution of the invention, technical scheme and beneficial effects carry out
It is further described, it should be understood that the above is only a specific embodiment of the present invention, is not limited to
The present invention, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should be included in this
Within the protection scope of invention.
