Summary of the invention

The purpose of this invention is to provide a kind of input video separately and with machine in the superimposed CD player of image, both having can be used as the normal optical disk player uses, also can be used as song-order machine uses, when using as song-order machine, CD mainly provides the vocal accompaniment music and with the captions of melody changes colour, can use the background video on the CD, also can use from the background of the outside video of importing of song-order machine as captions, especially can import the background of singer's video image from the outside with picture pick-up device as captions, allow the singer see the sight that oneself is sung in real time, not only enriched background but also heightened the enjoyment, the video file that being commonly used on the CD can also be done simultaneously the song subtitling background is compiled other dynamic or static images of single background color in advance, in the formation of this background color in whole image, if lack or handled by transparence, can not influence the associative perception of other image composition except that background color, aesthetic feeling, also can not influence the display effect of captions, there is the butterfly of other colors to dance in the air on the background color such as black, just can be added to this image and captions above the external video together simultaneously, remove background color and make the prospect of external video, make the composograph that displays abundant and beautiful more, such as making the butterfly that not only has captions to dance in the air in addition before singer's picture, snowflake, the prospect of dynamic or static frame and so on, because the video background with the outside input is main expressive object, the effect of prospect image is only to decorate external video, no longer be the main contents that we will show, therefore the prospect of dozens of minutes not only can not seem dull, but abundanter.

The present invention be achieved in that a kind of input video separately and with machine in the superimposed CD player of image: in a shell, power panel is arranged, CD drive, video disc drives decoding deck, audio frequency is arranged on the shell, video output terminal, it is characterized in that: also have video combining circuit in the shell, also has the external video input interface on the shell, video combining circuit can be an independently video combining circuit plate, also can be to make together circuit board with the disc drives decoding deck, can also be that video combining circuit and decoding circuit are integrated in the circuit board of making on the multifunction chip, the video combining circuit plate has two road inputs and one road output at least, wherein one road input is connected with external video input interface on the shell, another road input links to each other with the picture signal of disc drives decoding deck output, output links to each other with video output terminal on the shell, the two-way input signal is superimposed in the video combining circuit plate, by the video keying of CD decoding output is handled or other synthetic processing, remove background color, make background color see through outside input video, captions on the CD or prospect pattern or the two just can be superimposed upon the video front of outside input simultaneously like this.Synthetic rear video is linked on the television set by video output terminal, finishes the function that we need.Owing to randomness, the real-time of the outside video of importing, promptly can import singer's video, also can be other video, therefore make the picture of CD player output rich and varied, more interesting.
