[embodiment]
As shown in Figure 1, for the present embodiment, there is the structural representation relating to split screen process in the TV of split screen Presentation Function.Comprise multi-channel video input unit 100, split screen processing unit 200, display floater 300, micro-processor interface circuit 400 and motor 500.Multi-channel video input unit 100 receives multi-channel video signal, carries out video decode, and decoded multi-channel video signal is passed to split screen processing unit 200; Micro-processor interface circuit 400 receives split screen signal, will obtain screen rotation control signal and split screen control signal after split screen signal transacting, and screen rotation control signal controls motor 500 and drives display floater 300 90-degree rotation, and display floater is vertically placed.Split screen processing unit 200 by after decoded multi-channel video signal process on the vertical display floater placed longitudinal arrangement display at least two split screens.
Video input unit 100 receiving video signals, and vision signal is decoded.This vision signal both can be the vision signal of digital TV set-top box also can be computer video signal, accesses this video input unit 100 by multi-channel video signal interface or computer video signal interface.After receiving vision signal, by built-in Video Decoder to decoding video signal.
As shown in Figure 2, be the cut-away view of the split screen processing unit 200 of the present embodiment.Split screen processing unit 200 comprises split screen treatment circuit 210, memory 220, Graphics Processing circuit 230 and drive circuit 240.
Split screen treatment circuit 210 receives the split screen control signal that micro-processor interface circuit 400 sends, select span mode, read and data corresponding with the span mode of split screen control signal in memory 220, to the whole screen divider split screen region of display floater 300, and it is each split screen region allocation passage.
The related data of the multiple span mode of applicable screen partition is previously stored with in memory 220, according to corresponding span mode, split screen treatment circuit 210 can determine how region divides, the interval etc. between the position of picture distribution as corresponding in area size, signal source and picture.
Graphics Processing circuit 230 reads the signal of the information source of each passage, and the form for signal is arranged display transformation.
Drive circuit 240, by the Drive of row and column conversion in each split screen, makes image show and adapts to postrotational display floater.
The handling process with its split screen of TV display of said structure as shown in Figure 3, comprises the steps:
S1: receive split screen signal.Split screen signal can be the remote signal that remote controller sends TV, also can be by key-press input in computer, the signal transmitted by computer.This split screen signal can include the information of closing the order starting split screen and the span mode selected, namely the order starting split screen is allow motor operate and start the work of split screen processing unit, and the information of span mode then informs the span mode that split screen processing unit is selected.
S2: process is carried out to described split screen signal and obtains screen rotation control signal and split screen control signal.Split screen signal is sent by outside, needs to make motor and the collaborative work of split screen processing unit, therefore can will obtain the screen rotation control signal and the split screen control signal that control motor and split screen processing unit after split screen signal transacting.
S3: control display floater according to screen rotation control signal and rotate, and select span mode, divide split screen region.Screen rotation control signal makes display floater 90-degree rotation, vertically places.Split screen control signal starts split screen process, according to the data determination span mode relevant to span mode prestored in the information of the relevant span mode comprised in split screen signal and memory, and division split screen region.The information of relevant span mode as comprised in split screen signal specifies the double screen whole screen being divided into 16: 9, and have the division information of 16: 9 double screens mated with this television sizes in memory, this division information comprises the size, position etc. of each split screen.
S4: be each split screen region allocation passage, each passage reads the signal of the information source of corresponding split screen.Multi-channel video signal obtains the signal of the multi-information source of corresponding split screen number after decoding, is each split screen region allocation passage, for the signal-obtaining of the information source by correspondence to corresponding split screen.
S5: read the form of the signal of the information source of each split screen and carry out display transformation setting.The form of the signal of the information source in each split screen may be different, and carry out showing also needs to carry out some settings to each split screen.
S6: the column driver circuitry in drive circuit is exchanged, to adapt to the vertical display requirement of television image.So far formed the display that multi-channel video carries out split screen display, only display need be transferred to drive circuit, split screen display can have been realized.Because display floater have rotated 90 degree, if directly display is transferred to drive circuit, picture will overturn and distortion.Therefore be necessary Drive of row and column to exchange, make picture adapt to postrotational display floater.
S7: the signal of each split screen information source is converted to drive singal and transfers to display floater, split-screen display picture.Display is transferred to drive circuit, can split-screen display picture on a display panel.
