Description

With video player and the implementation method of timing code and control output

Technical field

The present invention relates to a kind of video player, relate in particular to a kind of video player and implementation method with timing code and control output.

Background technology

At present, digital movie player known to us has 2 large classes, the first kind is professional digital cinema server (being referred to as below professional player), and Equations of The Second Kind is practical player and the player (being referred to as below ordinary playing device) of Set Top Box or DVD and so on computer at ordinary times.Wherein professional player is supported DCI standard and SMPTE standard, with timing code output, has encrypting and decrypting function and the SMPTE standard time code output function (LTC OUT) of digital movie protection.But it is due to the object of digital copyright protecting; only directly support DCP packet format (the digital movie bag Digital Cinema Package and temporarily only support 2K 4K resolution of digital movie; can not directly support common at ordinary times RM, AVI, the film forms such as MKV.Although and ordinary playing device is supported common film form at ordinary times, do not support timing code (LTC) output, can not be used for the Synchronization Control of slave computer, can not use for projects such as 4D film, special efficacy controls.Professional server can not be supported multi-format, and common server can not do Synchronization Control and there is no digital movie defencive function, and both cannot directly support control command output, if configure in addition control system equipment, cost is high.Not easy-to-use, uneconomical, highly not integrated.Therefore, need a kind of birth of video player of new generation that can the above defect of customer service.

Summary of the invention

Object of the present invention is just to provide in order to address the above problem a kind of video player and implementation method with timing code and control output.

The present invention is achieved through the following technical solutions above-mentioned purpose:

A kind of video player with timing code and control output of the present invention, by video playback module, script editor module, time processing module, encrypting and decrypting module, document processing module, demonstration, module, execution output module and synchronization control module are set and form player, the signal transmission ends between modules interconnects.

A kind of video player implementation method with timing code and control output of the present invention, comprises the following steps:

(1) be written into the media file that needs broadcasting;

(2) whether be encrypt file to document processing module if carrying out identification, if encrypt file enters next step;

(3) proceed to encrypting and decrypting module and process, encrypting and decrypting module detects the secret key of deciphering of media file, if correct, displaying video, if incorrect, warn and stop;

(4) encrypting and decrypting module enters display module after verifying by media and carries out video playback output;

(5) in step (2) if not encrypt file, directly enter and show and module is set carries out video playback output;

(6) video playback module arranges module by video by demonstration and plays, and the correct time of video is outputed to time processing module simultaneously;

(7) time processing module converts the time receiving to standard media time of 25 frames per second, output to synchronization control module, synchronization control module contrasts the time of action executing file and the time obtaining, if false, output signal not, as truly, output action signal is to carrying out output module, carries out that output module converts order to RS232 or network signal outputs to execution hardware;

(8) document processing module detects whether load action executing file, if need to load, load motion file, and the timing node that needs are performed an action outputs to synchronous Executive Module; If do not loaded, detect whether need to make motion file, if do not needed, closing motion output; If need to make motion file, pop-up action editing interface, edits, and then preserves; When again playing media file, select to be written into action executing file.

Beneficial effect of the present invention is:

The present invention is a kind of video player and implementation method with timing code and control output, compared with prior art, the present invention can customer service the deficiencies in the prior art, under hardware configuration cheaply, can support normal conventional format video file to play, can support the encryption function of digital video packets, allow commercial digital video better provide, can support the timing code output of SMPTE standard, can also support the timely editor of special efficacy action script, preserve, read in, operation, not only reduce costs, and improve its function, have advantages of economical and practical, be conducive to promote.

Brief description of the drawings

Fig. 2 is implementation method flow chart of the present invention.

Embodiment

Below in conjunction with accompanying drawing, the invention will be further described: as shown in Figure 1: a kind of video player with timing code and control output of the present invention, by video playback module, script editor module, time processing module, encrypting and decrypting module, document processing module, demonstration, module, execution output module and synchronization control module are set and form player, the signal transmission ends between modules interconnects.The playing module of player, synchronization module, Executive Module height are integrated, have abandoned split-type structural in the past, make more compact structure, prices.The integrated Executive Module of player need to have Play Server, timing code change server in the past, to carry out three servers of server stacking.Only need now Play Server, directly export control signal.Synchronization module does not re-use traditional film time way of output, the reproduction time of directly obtaining media has omitted hardware polling, and pattern was so in the past: media play, and--> exports 16 system signals, and--> hardware conversion becomes can----the > execution that > carries out current schema: media play--> synchronizer is obtained signal--that > synchronizer is obtained signal of recognition time signal.

As shown in Figure 2: a kind of video player implementation method with timing code and control output of the present invention, comprises the following steps:

(1) be written into the media file that needs broadcasting;

(2) whether be encrypt file to document processing module if carrying out identification, if encrypt file enters next step;

(3) proceed to encrypting and decrypting module and process, encrypting and decrypting module detects the secret key of deciphering of media file, if correct, displaying video, if incorrect, warn and stop;

(4) encrypting and decrypting module enters display module after verifying by media and carries out video playback output;

(5) in step (2) if not encrypt file, directly enter and show and module is set carries out video playback output;

(6) video playback module arranges module by video by demonstration and plays, and the correct time of video is outputed to time processing module simultaneously;

(7) time processing module converts the time receiving to standard media time of 25 frames per second, output to synchronization control module, synchronization control module contrasts the time of action executing file and the time obtaining, if false, output signal not, as truly, output action signal is to carrying out output module, carries out that output module converts order to RS232 or network signal outputs to execution hardware;

(8) document processing module detects whether load action executing file, if need to load, load motion file, and the timing node that needs are performed an action outputs to synchronous Executive Module; If do not loaded, detect whether need to make motion file, if do not needed, closing motion output; If need to make motion file, pop-up action editing interface, edits, and then preserves; When again playing media file, select to be written into action executing file.
