Detailed description of the invention
The present invention provides the television set and many screen playing methods thereof that a kind of multi-screen plays, and is suitable for and image display arts, such as TV domain, computer monitor etc..One piece of telescreen is divided into multiple sub-screen, each sub-screen shows that each user likes the content seen, can individually play the audio frequency that sub-screen is corresponding, the sub-screen of oneself viewing can also be operated selecting by user, to reach in one piece of television main screen, different user is watched respective sub-screen simultaneously and is independent of each other.For making the purpose of the present invention, technical scheme and effect clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
Referring to Fig. 1, the television set that the multi-screen that the embodiment of the present invention provides is play pre-sets several sub-screens and terminal interface, and each sub-screen configures a pair earphone.Described television set includes processing module 10, controls module 20, display module 30 and sound module 40.The described processing module 10 video signal to gathering the input of several terminal interface, generates some groups of image subsignal harmony diphone signal respectively after carrying out matching and decoding process, image procossing and Audio Processing.Transmission after image subsignal mixing superposition in often group is shown by display module 30 to corresponding sub-screen.After sound subsignal in often group is encoded by sound module 40, bluetooth is sent to corresponding earphone broadcasting.Described control module 20 controls display effect and the system allotment of display module 30 according to remote signal.Each terminal interface is corresponding with a sub-screen, and the video signal of terminal interface input display and sound on corresponding sub-screen are play in corresponding earphone.If certain terminal inputs without video signal, then without display on corresponding sub-screen.
In the present embodiment, described processing module 10 includes signal gathering unit 110, signal decoding unit 120, graphics processing unit 130 and audio treatment unit 140.
Described signal gathering unit 110 gathers the video signal of several terminal interface input of television set, and these several video signals are carried out impedance matching so that it is it is transferred to signal decoding unit 120 after becoming corresponding some height screen signals that system can normally receive.Described video signal includes CVBS(CompositeVideoBroadcastSignal, Composite Video Baseband Signal) signal, YUV (also known as YCrCb) signal, HDMI(High-DefinitionMultimediaInterface) signal, RF(radio frequency) signal, VGA (VideoGraphicsArray) signal etc..As in figure 2 it is shown, the video signal based on these different-formats can be separately input in a sub-screen to show, before dispatching from the factory, pre-set each sub-screen show the video signal of which terminal interface input.As the first terminal interface (first terminal interface as counted from top to bottom in television set side) inputs CVBS signal, after signal gathering unit 110 processes, become the first son screen signal；Second terminal interface input YUV signal becomes the second son screen signal；The like until n-th terminal interface input n signal become n-th son screen signal.The number of terminal interface is identical with the number of sub-screen, and terminal interface which kind of signal external is determined by user, it is not limited as herein.Terminal interface on television set is prior art.
Described signal decoding unit 120 have employed the high performance TV chip with multi-channel decoding ability (each passage is a kind of signal of decoding simultaneously respectively), some height screen signals of input can being carried out multi-channel decoding, decoding image subsignal harmony diphone signal out is also transferred to graphics processing unit 130 and audio treatment unit 140 by some groups of corresponding image subsignal harmony diphone signal that generation system is capable of identify that respectively.First son screen signal becomes the first image subsignal and the first sound subsignal after signal decoding unit 120 processes；In like manner, the second son screen signal, the n-th son screen signal also become corresponding image subsignal harmony diphone signal, as shown in Figure 3.
Described graphics processing unit 130 also possesses band-wise processing ability, corresponding image subsignal carries out resolution and zooms in or out process so that it is becomes and meets this sub-screen and show required resolution；Also the display position of sub-screen is calculated simultaneously, makes image subsignal be shown on correct screen.
As long as it is to be appreciated that terminal interface external equipment, with regard to the video signal of its input of Real-time Collection, but being particularly shown which video signal, graphics processing unit 130 screen is selected to determine according to user.As being provided with 4 sub-screens, having 4 terminal interface 4 kinds of video signals of input, these 4 kinds of video signals all can carry out above-mentioned collection and decoding process.If user selects split screen to show, then 4 kinds of video signals are transmitted separately to the sub-screen of correspondence and display.If user selects display full frame, when 4 kinds of video signals all input, graphics processing unit 130 shows to display module after processing the video signal that the first terminal interface inputs；During only one of which terminal interface incoming video signal, graphics processing unit 130 process this terminal interface input video signal after, output show to display module.If only 2 terminal interface external equipments, then the corresponding video signal of sub-screen display that these 2 terminal interface are corresponding, other sub-screens are without display.In the specific implementation, user selects to be displayed in full screen the video signal of which terminal interface also by remote controller.
Graphics processing unit 130 according to preset order (as according to from left to right, from the order under upper) by image subsignal and corresponding sub-screen one_to_one corresponding, and the image subsignal (corresponding with the coordinate points in corresponding display position by each pixel in image subsignal, to determine which coordinate points shows which pixel) that the distribution of each sub-screen is corresponding.Assuming as shown in Figure 4, the number of current shown sub-screen is 4, according to preset order respectively the first sub-screen, the second sub-screen, the 3rd sub-screen, the 4th sub-screen.The video signal (by that analogy) of the first sub-screen display the first terminal interface input.The resolution of full screen is 3840*2160, and each sub-screen of graphics processing unit 130 is divided equally, then the resolution sizes of each sub-screen is: 1920*1080.Corresponding coordinate position on screen is as shown in Figure 4.The 4 road image subsignals then inputted need to carry out the process that zooms in or out of resolution, if the resolution of image subsignal is less than 1920*1080, it is necessary to zoomed into the picture signal of 1920*1080 resolution；Otherwise then it is reduced into 1920*1080 resolution, makes the image subsignal of input meet the demand of sub-screen resolution.It is to be appreciated that the sub-screen of described television set is divided into n in advance, namely most multipotency shows n screen simultaneously.But during actual viewing, user is likely to use full frame, full frame, without coordinates computed (be equivalent to calculate the coordinate on four summits of screen, this coordinate it is known that therefore without calculating)；If resolution is unsatisfactory for full frame requirement, the convergent-divergent carrying out correspondence processes, if meeting, does not process.
It addition, image subsignal also can be carried out image procossing by graphics processing unit 130, the image procossing such as including image quality adjustment (including the process of the aspects such as definition, contrast, color of image) and motion compensation, to reach better image effect.The image subsignal of each sub-screen after process is transferred to display module 30 by graphics processing unit 130.
Each image subsignal is carried out mixing superposition by described display module 30 according to display position, it is specially and each image subsignal is respectively taken a frame, each pixel point value of each image subsignal taken out is stored in a corresponding two-dimensional matrix, the resolution of the corresponding each image of the size of matrix.Then need the position of display to be overlapped according to TV two-dimensional matrix corresponding for each image subsignal, make each two-dimensional matrix become a global matrix shown for full screen.The resolution being sized to TV actual screen of this global matrix.Each pixel point value of the value of each element just corresponding TV in such global matrix, thus realizing the coupling of picture signal and telescreen.Finally, global matrix is converted into the format signal (such as V-by-OneHS signal) that can show for telescreen by display module 30 again, and the corresponding region exported to display screen displays.Image subsignal is mixed and is superimposed as full frame signal, and owing to carrying out corresponding by two-dimensional matrix with the position needing display, only corresponding coordinate points just can show the pixel point value of correspondence, shows the picture of mistake after so can avoiding mixing.
While image subsignal carries out processing, sound subsignal is also carried out corresponding process.Signal decoding unit 120 exports each sound subsignal and processes accordingly to audio treatment unit 140.Described audio treatment unit 140 also has a band-wise processing ability, processes and mainly includes the high pitch of voice parts, the reinforcement of bass or weaken, surround sound, the various acoustic patterns such as stereo process, and sound power amplifies the adjustment of curve of output.Sound subsignal after audio treatment unit 140 process is transferred to sound module 40.
Due to the video different in same display screen display, the sound that each sub-screen is corresponding also differs, and in existing television set, unique loudspeaker can not meet audio demand.In order to make each user can hear the sound of sub-screen used by oneself, and the sound of each sub-screen does not interfere with each other.The present embodiment adopts several earphones with television set pairing to listen to.Described earphone can be bluetooth earphone, and left earphone and right earphone in every pair of earphone can be linked together by data wire, facilitate user to wear.Also can left earphone and right earphone being separated and label distinction, as 1L represents the left earphone of the first sub-screen, 3R represents the right earphone of the 3rd sub-screen；Such a pair earphone can simultaneously for two users.
Then accordingly, described sound module 40 domestic demand arranges several bluetooth modules, and the number of bluetooth module is identical with the number of the number of sub-screen, earphone.Every pair of earphone and a bluetooth module pairing, as shown in Figure 5.After each bluetooth module recompiles after the corresponding sound subsignal to receiving, bluetooth approach is adopted to be sent to corresponding earphone.Sound subsignal after the earphone coding to receiving is decoded, and the sound sending correspondence is listened to for user.Thus realizing independently listening to of each sub-screen.
When user selects full screen display, then only one of which sound subsignal, it can pass through the first earphone and play；When user selects to televise, power amplifier module existing in television set after carrying out power amplification, can also transmit to the existing loudspeaker broadcasting of television set.If there being the sound subsignal of more than 2, then obtain sound subsignal after only having the video frequency signal processing of the first terminal interface input, the first earphone can be passed through or loudspeaker broadcasting.
As shown in Figure 6, it is assumed that the first terminal is interfaced to the 4th terminal interface and inputs CVBS signal, HDMI signal, RF signal, YUV signal respectively.First pass through each passage in signal gathering unit 110 be acquired respectively, impedance matching；Decode respectively again through each passage in signal decoding unit 120.The CVBS image subsignal of generation, HDMI image subsignal, RF image subsignal, YUV image subsignal transmit after carrying out image procossing in the respective channel to graphics processing unit 130, sending and mix superposition to display module 30, the corresponding sub-screen finally exported to display screen displays.After the transmission of CVBS sound subsignal, HDMI sound subsignal, RF sound subsignal, YUV sound subsignal carries out acoustic processing to each passage of audio treatment unit 140, transmit again and be encoded to the corresponding bluetooth module of sound module 40, adopt bluetooth approach to be sent to corresponding earphone.
In the present embodiment, processing module 10 completes the respective handling of audio-video signal and plays display, controls module 20 and completes to control operation accordingly.Described control module 20 includes RCU 210, scheduling unit 220 and UI unit 230.
Described RCU 210 is for realizing multi-user's manipulation to each sub-screen user interface.Existing television set only one of which remote controller is to being operated, the present embodiment is in order to realize multi-user operation, each sub-screen one IR remote controller of configuration, and each remote controller is different for the same function command of each sub-screen, the key assignments of remote keying that sends, so can control a sub-screen respectively by independent remote controller, even if carrying out identical remote manipulation, without influencing each other between sub-screen.RCU 210 identifies which sub-screen is the infrared remote signal received belong to, and the telecommand transmission resolving to correspondence performs corresponding operation to UI unit 230.
When RCU identification telecommand is internal memory operation instruction (such as relating to internal memory cleaning or Memory Allocation or memory consumption query display etc.), also can be sent directly to scheduling unit 220 and carry out corresponding internal memory process.During as cleared up instruction for internal memory, scheduling unit 220 can carry out internal memory cleaning, to vacate more internal memory, accelerates system and runs.
It is divided into several sub-screens based on television set, in order to make each screen independently to operate, controls and coordinate the human-computer interaction interface of each sub-screen by UI unit 210.Described UI unit 210 is for showing the custom menu of each sub-screen；It also communicates with scheduling unit 220, sends the operational order of user to user menu to scheduling unit 220, in order to scheduling unit 220 is operated distribution and the execution of instruction；Scheduling unit 220 also execution result is fed back to UI unit 210, UI unit 210 control display module display corresponding perform operation.
