Detailed description of the invention
Fig. 1 is a kind of flow chart of the control method for playing back of video file in the embodiment of the present invention；
Fig. 2 is a kind of structural schematic diagram of the broadcasting control system of video file in the embodiment of the present invention.
Specific embodiment
Technical solution of the present invention is described in detail below by attached drawing and specific embodiment, it should be understood that this hair
Particular technique feature in bright embodiment and embodiment is the explanation to technical solution of the present invention, rather than is limited, not
In the case where conflict, the particular technique feature in the embodiment of the present invention and embodiment be can be combined with each other.
It is as shown in Figure 1 a kind of flow chart of the control method for playing back of video file in the embodiment of the present invention, this method packet
It includes:
S1 determines whether the video file is deposited when receiving control instruction of the user terminal for playing video file
In corresponding finger print information, wherein the finger print information characterizes operator's copyright；
Firstly, the copyright in order to protect video file, in embodiments of the present invention, by addition fingerprint letter in video file
Breath, the finger print information characterize the copyright of video file, and the specific mode for adding finger print information is as follows:
It opens set-top box entry condition and receives service system finger print information and video record, open set-top box entry condition and connect
The system module of receipts system, opens set-top box and starts USB drive module, descrambles ciphered program by condition receiving system, passes through
The finger print information that condition receiving system receiving front-end is sent.
Need exist for explanation be the condition receiving system system (CA), abbreviation CA technology, be broadcast television industry such as
Media protection term used in the broadcast systems such as wired, satellite, ground.TV signal or other data are at front end (transmitting terminal)
It is scrambled (Scrambling), various forms of broadcasting networks is then dispensed for and broadcasts.The technology guarantees that authorized user (has propped up
Pay correlative charges) TV programme and other service business that he has subscribed can be received, unauthorized user then can not be watched or be used
Related service.Preventing the received method of unauthorized user is to program scrambling and to receive control, only into the user of authorization offer
Key needed for holding descrambling.Authorized user descrambles digital signal using key and relevant device.Key is usually to utilize smart card
Or the relevant technologies prevent the unauthorized theft of key.CA technical requirements can protect user's unrestricted choice watch program right and
The interests of broadcast dealer and program provider can be protected.
Described condition receiving system system (CAS) module, specifically includes: the driving of CA card module follows 7816 agreements, into
Row descrambling ciphered program.
The video record (English: Personal Video Recoder, abbreviation: PVR), the outstanding feature of PVR is
Using hard disk as storaging medium, local magnanimity buffer area and huge program repository are established, digital processing technology is utilized
Program is controlled and is managed.
The front end, specifically includes: capital equipment encoder, multiplexer, adapter, scrambler etc., condition reception system
Unite (CAS), Subscriber Management System (SMS), electronic program guide information system (EPG).
The finger print information refers to that operator sends some prompt informations and operator for copyright protection by front end
Some copyright informations, set-top box shows specific fingerprint content by service system when user watches program.
It performs fighting video record function and when starting recorded video in user terminal, under the operator for determining whether it has received video
The video file of recording is associated with, and finger print information by the finger print information of hair if receiving the finger print information with finger print information
Content and the video file of recording be placed under same file adds.
Further, in order to improve the accuracy that finger print information is shown, so before the content for saving finger print information, also
By according to the starting point of video record, the display time point of finger print information is determined, for example, showing after video record 1 minute
Finger print information.
Also by according to the duration of video record, the display duration of finger print information is determined, for example, the total duration of video record is
1 hour, it is determined that a length of 1 hour when the display of the finger print information, an only citing herein is specific to show that duration root
It is adjusted according to application scenarios, does not do specific restriction herein.
Determine finger print information display time point, display duration after, system can be by the video file and fingerprint of recording
Information, finger print information display time point, finger print information display duration association, and store add to same file under, to protect
Card finger print information can accurately be shown.
After based on above-mentioned setting, when user terminal carries out the broadcasting of video file, system will determine video first
File whether there is corresponding finger print information, if in the presence of thening follow the steps S2, if being not present, thening follow the steps S3.
S2 shows finger print information in playing video file；
Determine video file exist to finger print information when, it is first determined the finger print information associated display time
Point and display duration will directly show on a display screen that the fingerprint is believed according to display time point when playing the video file
The content of breath, and it is continuously display according to display duration progress.
S3, direct playing video file.
If determining video file there is no when corresponding finger print information, then illustrate that there is no copyrights to ask for the video file
Topic, system will directly play the video file at this time.
Provided method through the invention, when carrying out video record, system is by the video file of recording and operator
The finger print information issued is associated, and is stored under same file folder, is carrying out secondary forwarding operator by recording means
Program when, if playing the recorded video, system will directly display the finger print information of operator, to avoid not passing through
Operator relays in the case where authorizing or the problem of as other commercial uses, improves video file protecting effect, protects
Operator's copyright.
