Wherein,
The video source data obtains module 31, the video source data read in advance for obtaining a line；
The Nesting Drawing Mould 32, for carrying out picture mosaic processing to a line video source data；
The output module 33, for by picture mosaic treated video source data exports to display frequency curtain target line position
It sets.
In an alternative embodiment of the invention, described device further include: the pre- read through model 34 of video source data and storage
Operation module 35；Wherein,
The pre- read through model 34 of video source data, for before obtaining the video source data that reads in advance of a line, in advance

The storage operation module 35, for a line read in advance or multi-line video source data to be stored in video cache
Qu Zhong.
Specifically, the pre- read through model 34 of video source data, for reading a line video source number in advance in the following manner
According to:
The video data being successively read on the corresponding multiple channels of a line video source data.
Specifically, as shown in figure 4, the pre- read through model 34 of the video source data include: configuration information reading submodule 3401,
Location information acquisition submodule 3402 and video data acquisition submodule 3403；Wherein,
The configuration information reading submodule 3401, for successively being read from the corresponding video data register in multiple channels
Take the configuration information of updated video data in respective channel；
The location information acquisition submodule 3402, for obtaining the location information in the video data configuration information；
The video data acquisition submodule 3403, for the corresponding position acquisition video of location information from the acquisition
Data are simultaneously stored in video cache area.
Specifically, the configuration information of the video data includes: the location information of video data and the size of video data.
Specifically, the Nesting Drawing Mould 32, for being carried out at picture mosaic to a line video source data in the following manner
Reason:
When the video data in a line video source data on two or more channels is to stack display, according to
What pre-set priority determined the video data on described two or more than two channels stacks order；Alternatively, to described
Alpha effect is arranged in video data on two or more channels；
When the size of the video data on the channel for forming a line video source data and the display size of respective channel
It is the display size of the respective channel by the size adjusting of the video data when mismatch.
Specifically, the output module 33, in the following manner by picture mosaic treated video source data exports to
Show the target line position of frequency curtain:
The video data on picture mosaic treated multiple channels is exported to the display position in each channel respectively.
In the specific implementation process, above-mentioned video source data obtains module 31, Nesting Drawing Mould 32, output module 33, video
The pre- read through model 34 of source data, storage operation module 35, configuration information reading submodule 3401, location information acquisition submodule 3402
And video data acquisition submodule 3403 can be by central processing unit (CPU, the Central in video display apparatus
Processing Unit), microprocessor (MPU, Micro Processing Unit), digital signal processor (DSP,
Digital Signal Processor) or programmable logic array (FPGA, Field-Programmable GateArray)
To realize.
Using example
Multi-channel video display methods provided in an embodiment of the present invention is discussed in detail below by a specific example.
As shown in figure 5, the video data for nine channels shows that frequency curtain, the display frequency curtain are divided into nine viewing areas
Domain, the corresponding channel in each display area, display frequency curtain is divided into three rows from top to bottom, specifically, the first row includes channel
It includes the channel channel 7- 9 that the channel 1- 3, the second row, which include the channel channel 4- 6, the third line, shows screen from up to down with behavior list
Position carries out video data refreshing.
Each channel is each equipped with two video data registers in Fig. 5, one of them is ping register, another
For pang register, it is clear that, described two registers ping-pong register each other.Described two registers are by FIFO team
Column are realized.
When two registers, one of them is used to store the configuration information of video source data, another is just used to read view
The configuration information of frequency source data does table tennis processing using two video data registers, the continuous of video source data may be implemented
Processing.For example, it is assumed that a channel configuration is there are two register, one is A, another is B, then, deposits when by video source data X
When being put in the register in the channel, the configuration information of the first frame of X is stored in A first, then the configuration of the second frame
Information is stored in B, and third frame is stored in A again, is so stored in turn；It, can be from A when storing the configuration information of the second frame
The middle configuration information for reading first frame can be read to walk matching for the second frame from B after then B has stored the configuration information of the second frame
Confidence breath, material is thus formed ping-pong mechanisms.
When the display engine of video display apparatus needs to obtain the one-frame video data in first channel, position is read first
Realized in the channel two fifo queue foremosts of video data register and the video data that is ready for confidence
It ceases, stores the configuration information of one-frame video data in fifo queue each time, include video data in the configuration information
Therefore storage location information obtains video in the storage location that display engine can be indicated directly to the storage location information
Data are simultaneously stored in screen buffer.
Still as shown in fig. 5, it is assumed that the display engine of video display apparatus has read three row video source datas in advance, that is,
The display engine has read three row video source datas from nine channels respectively；When the display engine needs to refresh
When the video pictures of a line, processing is followed the steps below:
Step 1 obtains the first row video source data；
Specifically, display engine obtains pre-stored the first row video source data from video cache area, described first
Row video source data includes the video data in the channel channel 1- 3.
Step 2 carries out picture mosaic to the video source data；
Specifically, display engine determines the size of video data in the channel channel 1- 3 respectively, and determine the channel channel 1- 3
Display size, when in respective channel the size and respective channel of video data display size mismatch when (that is, the channel
The size of upper video data is not equal to the display size in the channel), it is institute by the size adjusting of video data in the channel
State the display size in channel.
Assuming that between video data in channel 1 and channel 2, there are gaps, then upper spy is filled between channel 1 and channel 2
Different color keeps the picture in channel 1 and channel 2 continuous.
Step 3 exports the video data on multiple channels after picture mosaic to the target line position of display frequency curtain.
Specific to the example, show that the target line position of frequency curtain is display frequency corresponding to the first row video source data
The region of the first row in curtain；The region is made of the display area in channel 1, channel 2 and channel 3.
Specifically, by the data in the channel 1 after picture mosaic export to the display area in channel 1, will be in the channel 2 after picture mosaic
Data export and export to the display area in channel 1, by the data in the channel 1 after picture mosaic to the display area in channel 3.
It is corresponding, when display engine needs to refresh the video pictures of the second row or the third line, it is only necessary to according to it is above-mentioned
Refresh the similar method processing of the method for the first row video pictures.
