Description

A kind of from the outside input video and the computer song-order machine of overlapping text and prospect with it

Affiliated technical field

The utility model relates to a kind of from the outside input video and the computer song-order machine of overlapping text and prospect with it.

Background technology

At present, because of computer song-order machine compatibility good, it is convenient to add song, used at singing-hall in a large number, places of business such as karaoke halls, computer requesting song software role is to search song in the computer song-order machine, functions such as management song storehouse, the song major part is directly with VCD, the song of DVD Karaoke dish the inside copies to computer song-order machine unit hard disk or webserver hard disk the inside, also there are some to be compressed into forms such as MP4 for the minimizing capacity, make the song index file again, so that the user can find required song from the requesting song software interface, each head of these songs all has a fixing image, be generally original singer's performance or some scene, images such as song and dance, because these images are by some professional video display company shooting and producings, they have to masses plays, copyright such as duplicate, just family's right of broadcasting with the CD sale, along with putting more effort of national intellectual property protection, a lot of distributors that play Karaoka, experiencing or be about to face some video display company lawsuits, it is passive to be in, ineffective status, buy the projection power of numerous song images, operating cost is too high, in a dilemma again; The more important thing is: these songs reach the time picture always in several years, and the consumer does not have and do not think dull, dull.In addition, also occurred a kind of software at present, can external video be adopted into computer by capture card, can external video is synthetic with song subtitling by operating software, also can follow computer hardware, operating system is integrated into a kind of song-order machine that has with the utility model similar functions together, such as the electric MTV software of indigo plant, but because will finish synthetic the processing to the huge real-time video of amount of information, therefore to computer performance, the stability requirement height, the cost height, if reach the definition of standard DVD, be equivalent to P4 at present on the market, 3.0G the configuration of high-end computer also also have picture to delay, the sound picture asynchrony phenomenon, and complicated operation, the more important thing is because want local runtime video composite software, local hard drive and operating system support must be arranged, can't adapt to singing-hall, the no flaking network system that places of business such as karaoke halls are a large amount of uses, not only increased system cost significantly, the difficulty of safeguarding also greatly increases, to the singing-hall that has existed, karaoke halls, because all disposed low configuration computer, transformation can cause very big waste.

Summary of the invention

The purpose of this utility model provides a kind of from the outside input video and the computer song-order machine of overlapping text and prospect with it, the function that common computer song-order machine is promptly arranged, play common song image, also can be from outside input video image, take singer's the image or the image at performance scene, dancing hall hall even the image of a certain television channel such as video camera and send into the background that private room is made song, and computer requesting song software provides the vocal accompaniment music and with the captions of melody changes colour, can also play simultaneously the public prospect or the specific prospect video file of some song that supply the song random call in the hard disk, captions and dynamically or static pattern prospect video front externally, when particularly client oneself sings, decorate some beautiful or interesting prospects of making laughs before his video image in real time, waft from the head down such as petal, or insect gets over from face, fully interactive, not only abundant but also joyful, certainly we can also keep the protoplast original singer's that fraction client misses potter very much MTV Kara OK songs, but because quantity is few, expense is much lower naturally, and other do not have the public use of the simple music of master picture, the broadcast expense is lower, only sing when singing these songs or image frame that image that the hall performance is on-the-spot or miscellaneous equipment provide is made the background of captions with client oneself, fully interactive, not only abundant but also joyful, simultaneously also respected copyright, legitimate.

The purpose of this utility model is achieved in that a kind of from the outside input video and the computer song-order machine of overlapping text and prospect with it: include the host computer part, which comprises at least shell, power supply, computer main board, CPU, internal memory, display card, audio frequency, video output terminal, it is characterized in that also containing video input terminal and video combining circuit plate, the video combining circuit plate has two road inputs and one road output at least, wherein one road input connects the display card output of host computer part, it provides captions and prospect video image signal, other one road input connects the external video input terminal, one road output connects video output terminal, outputting video signal is to display devices such as television sets, as required, two-path video input terminal and video combining circuit plate and video output terminal also can be fixed in another shell separately, with video line with the video output terminal of common computer song-order machine therewith a video input terminal on the shell link to each other, form and common computer song-order machine with similar set-top box are formed song-order machine described in the utility model, reach same purpose.In this mode, the video file of prospect is compiled the complete image that contains a certain background color, this background color is in the formation of whole image, if lack or handled by transparence, can not influence the associative perception of image composition, aesthetic feeling, also can not influence the display effect of captions, these road captions and prospect video together are superimposed upon the video front of the outside input in another road in video combining circuit, background color is scratched, appear external video, only stay captions and dynamically or static pattern prospect video front externally, reach the purpose of real-time overlapping text and prospect, prospect also can have foreground picture by special playing circuit generation or song itself, in the entire process process, the synthetic stack of video image, scratching the picture processing is finished by the video combining circuit plate, partly irrelevant with host computer, the host computer part is only exported captions and prospect, configuration requirement to host computer is low, the no dish terminal computer main frame of no flaking network system also can meet the demands, can significantly reduce hardware cost, remove the expenses such as hard disk of terminal computer main frame from, safeguard simple.
