Abstract
The invention provides a video fingerprint generation method and a video fingerprint generation system. The method comprises the steps of A, generating a first content video stream including video copyright information and a second content video stream including video content information; B, respectively inputting the first content video stream and the second content video stream to a playing device via an independent transmission protocol; and C, stacking the video copyright information of the first content video stream on the second content video stream, and outputting the second content video stream stacked with the video copyright information of the first content video stream to a video image in which the video copyright information is located at a predetermined position. The position of the video copyright information in the video image is randomly changed once every preset time. A copyright identifier is added into the output video image in a way of independently transmitting and stacking on the image, thus the copyright identification information can be efficiently added into the original video image; furthermore, the position and occurrence time of the copyright identifier are random, a screen recorder can be traced via the copyright identification information, the original image is effectively prevented from being stolen by the screen recorder, and thus pirate copies are avoided.

Detailed description of the invention
The present invention provides a kind of video finger print to generate method and system thereof.For making the purpose of the present invention, technical scheme and effect
Fruit is clearer, clear and definite, and the present invention is described in more detail for the embodiment that develops simultaneously referring to the drawings.Should be appreciated that this place
The specific embodiment described, only in order to explain the present invention, is not intended to limit the present invention.
As it is shown in figure 1, be a kind of video finger print generation method of the specific embodiment of the invention.Described method includes walking as follows
Rapid:
S100, generation include the first content video flowing of video copy information and include the second content of video content information
Video flowing.Above-mentioned first content video flowing and the second audio content stream can be all the video information of in-time generatin, or in advance
First record, the video information being stored in playback equipment or other variety classeses and the video flowing of type.
Concrete, the method for described generation video copy information includes:
First, the video copy information corresponding with the second audio content stream is obtained.Then, according to user instruction, arrange
The display parameters of described video copy information, generate described first content video flowing.
In actual application, described display parameters may include that the display of video copy information/hide, transparency,
Display duration and position coordinates etc., say further, can show random time, random site, student, company, mobile phone etc.
Information.Certainly, described video copy information can be specifically Word message, or the colored or pictorial pattern mark etc. of black and white
Any suitable video copy information (mark).
S200, described first content video flowing and the second audio content stream are respectively adopted independent host-host protocol input extremely
Playback equipment.
S300, the video copy Information Level of described first content video flowing are stacked on described second audio content stream, pass through
Playback equipment output has the video image of video copy information (as it is shown on figure 3, use similar figure layer stackup in precalculated position
Mode forms each frame of video).
Wherein, described video copy information stochastic transformation at every predetermined time is once in the position of video image.
The mode using the above-mentioned figure layer stackup being similar in image procossing stamps copyright in output video image
Information approach, convenient and swift, compared with existing synthetic method, the required time greatly reduces.It is additionally, since independent biography
Defeated, it is possible to change the position of video copy information easily, randomness increases, and effectively raises and removes video copy information
Difficulty.
Further, in a particular embodiment of the present invention, at interval of the N second the most random video copy information that changes at video
Position in image.N is the arbitrary random integers between 1-30.By this mode, video copy information is in video image
Appearance position, time of occurrence is at random.If wanting to remove or desalination logo, the watermark (copyright information) of Word message needs
Video being carried out process frame by frame just can be completely eliminated, workload is very big, and the difficulty removing video copy information greatly increases
Add.
More specifically, change at random video copy information with the following method can specifically be adopted:
First, in the viewing area of playback equipment, set up straight vertical angle coordinate system (including setting up initial point and coordinate axes).
Then, realized the change at random of position by the random position coordinates changing described video copy information, for example, it is assumed that display
The x-axis scope of screen is-100 to 100, and y-axis scope is-100 to 100, when carrying out change in location the most each time, respectively at above-mentioned x
Random number is chosen, as the position in another frame of video of described video copy information (watermark) in the range of axle scope and y-axis
Coordinate thus realize the change at random of its position.
Present invention also offers a kind of video finger print and generate system.As in figure 2 it is shown, described system includes:
Video copy information generating unit 100, for generating the first content video flowing including video copy information；By institute
State first content video flowing to be inputted to playback equipment by independent host-host protocol；
Video content information signal generating unit 200, for generating the second audio content stream including video content information；By
Two audio content streams are inputted to playback equipment by independent host-host protocol；
Playing control unit 300, in the video copy Information Level of described first content video flowing is stacked in described second
Hold on video flowing, be there is in precalculated position by playback equipment output the video image of video copy information；And every predetermined
Time stochastic transformation the most described video copy information in the position of video image.
Concrete, described video copy information generating unit 100 includes:
Video copy data obtaining module 110, for obtaining the video copy information corresponding with the second audio content stream
And video copy information parameter setting module 120, for according to user instruction, arranging the display ginseng of described video copy information
Number, generates described first content video flowing.
Further, described display parameters include: the display of video copy information/hide, transparency, display duration and
Position coordinates.
It is also preferred that the left described " predetermined time " is the scope arbitrary random number between the 1-30 second.I.e. at interval of the N second just with
Machine changes video copy information position in video image.N is the arbitrary random integers between 1-30.
More specifically, described player control unit 300 is additionally operable to, and sets up straight vertical in the viewing area of playback equipment
Angle coordinate system, changes the position coordinates of the most described video copy information at random at interval of the predetermined time.
It is understood that for those of ordinary skills, can according to technical scheme and this
Bright design in addition equivalent or change, and all these change or replace the guarantor that all should belong to appended claims of the invention
Protect scope.
