Description
One, technical field:
The present invention relates to mobile phone, panel computer, PDA or other embedded system, belong to areas of information technology, particularly relate to a kind of method and system and application that the many pictures of insertion-type media player show and control that be used for.
Two, background technology:
Existing insertion-type media player comprises: MP3, MP4, media-player software, system and device that mobile phone, panel computer or PDA are embedded all do not support many pictures to show and control, only support the demonstration and the control of single picture.Realize the demonstration of many pictures and picture-in-picture and matrix TV (video wall) that control only limits to TV, promptly a plurality of TVs are connected on the hyperchannel TV signal receiver.
At present, TV and video wall realize that picture-in-picture and many pictures show the basic two or more tuners of configuration that adopt, and promptly main tuner and secondary tuner just can have picture-in-picture function.According to the difference of circuit design, the picture of secondary tuner can be done various forms of variations: can move for four jiaos at screen such as little picture, secondary picture can amplify and dwindles, and can make key frame and secondary picture respectively account for half about on the screen, becomes the double vision window; Also can make key frame keep showing that current program is constant, and make secondary picture browse other channel etc.The multi-functional picture-in-picture of TV comprises picture-in-picture, two picture, channel browsing, stroboscopic, static and handoff functionality.
The picture-in-picture of TV is exactly the content that can show small one and large one two programs simultaneously, also can close little picture, switch between two pictures etc.The technology type that traditional analog television and Digital Television realize seemingly, and is also different.
The traditional analog television picture-in-picture is divided into two kinds of video picture-in-picture and radio frequency picture-in-pictures.Have only a tuner and image channel that the TV signal of receiving channels is provided in the video picture in picture TV set, another is the vision signal of external video recorder or video disc player output, enters from the AV input terminal, also claims single tuner picture in picture TV set; Two high-frequency tuners and image channel, sound channel are then arranged in the radio frequency picture in picture TV set, main, sprite each with put in a cover, the image, circuit such as vision signal processing receives two simultaneously and overlaps the rf tv programs.Claim the double high-frequency head picture in picture TV set again.
The digital high-frequency tuner of Digital Television is the Primary Component that TV can receive cable broadcasting signal.Digital Television is changed into anolog TV signals digital signal or direct receiving digital television signal earlier, compress, transmit, receive, handle, store, write down and control, receiving terminal at first will carry out high frequency amplification, comparison process, channel-decoding and demodulation through digital TV tuner, and then carries out going back original image harmony sound after the processing such as source coding through the receiver back-end circuit.The numeral high-frequency tuner not only comprises the important indicator of original traditional colour TV, and difference is also very big on detection methods such as phase noise, non-linear index and locking time.When analog television tuner receives anolog TV signals, the high-frequency TV signal of many different frequencies is transformed into a fixing intermediate frequency output, finishes moving of frequency spectrum.During digital TV tuner receiving digital broadcast TV signal, not only to finish the frequency spectrum shift function that analog tuner will be finished, separate the mediation channel-decoding but also will finish.The picture-in-picture of Digital Television is realized comprising two a plurality of digital high-frequency tuners, realizes picture-in-picture.If digital TV set-top box realizes that picture-in-picture is also similar, digital TV set-top box comprises two digital high-frequency tuners, when output, adopts the video superimpose technology, and synthetic one road video outputs on the TV.The TV of this moment is only as display device.
Media player in existing insertion-type media player and the computer system, all adopt medium digital transmission and digital media storage technology, can only play and control single medium, can not realize that a plurality of medium realize that on same display medium many pictures show and the function of control.Its display medium comprises: the medium of CRT, LCD, LED and other display media picture.
