Embodiment one

Fig. 1 shows the flow chart of the implementation method of the multi-display control system provided by Embodiment 1 of the present invention, wherein each display control system includes multiple channels, and the functions of the multiple channels can be the same or different , each channel implements all or part of the image processing functions that each display control system can implement.

In S101, when the channel configuration of any one of the display control systems in the multi-display control system cannot meet the current image processing requirements, call an idle channel in other display control systems according to the channel configuration;

Specifically, any display control system receives the image data to be broadcast by any display control system, splits the image data into multiple layers, and confirms whether the channel configuration of any display control system can complete the Processing of multiple layers, when the channel configuration of the channel in any one of the display control systems cannot complete the processing of the multiple layers, at least one of the multiple layers is sent to other Display control system for processing.

In this embodiment, when the channel configuration of a certain display control system in the multi-display control system cannot meet the current image processing requirements, for example, it may be that the number of channels of the display control system cannot meet the current image processing channel number, or it may be If the channel function of the display control system cannot meet the needs of image processing, you can call free channels to other systems according to the configuration of the display system to meet the current image processing requirements of the display control system. For example, if the channel of the display control system If the quantity lacks 1 processing channel, call a channel to the display control system with free channels, if the channel function of the display control system is not configured with the rotation function, call the channel with the rotation function to other display control systems equipped with the rotation function .

In S102, any one of the display control systems processes the input image data according to its own channel and channels in other display control systems called.

In this embodiment, specifically, any one of the display control systems receives image data processed by other display control systems on the at least one layer, and combines the image data received by the selection unit with the currently displayed The image data of other layers in the multiple layers processed by the control system are superimposed and sent to the display device for playback.

Optionally, after S102, the method further includes: outputting the processed image data to one or more display devices for display.

In this embodiment, the channel configuration is channel number or channel function, specifically:

When the number of channels contained in any display control system in the multi-display control system cannot meet the image processing requirements, then according to the number of channels, call the idle channels in other display control systems, and according to its own channel, and the called Other channels in the display control system process the input image data.

When the channel function contained in any display control system in the multi-display control system cannot meet the image processing requirements, then according to the channel function, call the idle channel function in other display control systems, and according to its own channel function, and Call other channel functions in the display control system to process the input image data.

In this embodiment, each display control system includes multiple channels, and each channel can be configured with different functions, that is, the functions of each channel are made unequal, and the functions realized by each channel can be adjusted according to actual needs. Add, delete, merge, split, or adjust order. For example, the function of a channel may include functions such as conversion between formats, image rotation, and scaling, and the function of a channel may only include conversion between formats.

Furthermore, all or part of the post-processing functions may be divided into individual channels and then superimposed, or all or part of the channel processing functions may be put into the superimposed image post-processing.

In this embodiment, the multiple display control systems can be configured with different functions except the channels, and the structures of other parts can be the same or different, which is not intended to limit the present invention.

For ease of understanding, the implementation method of the multi-display control system of this embodiment is described below with a specific implementation example, but not limited to the situation of this implementation example:

The following takes the dual display control system as an example, as shown in Figure 2, the dual display control system includes: display control system 1, display 1, display control system 2 and display 2, display control system 1 and display control system 2 Both include N channels (layers), and N is a positive integer greater than 1. Among them, channel 1 in display control system 1 and display control system 2 supports functions such as conversion between all image formats, image rotation, and scaling. The other channel 2 to channel N only support conversion between some formats, and do not support functions such as image rotation and scaling. Layer post-processing, etc. is the processing after all layers are superimposed. Each channel in the display control system 1 and display control system 2 is equipped with a strobe switch and a number of selectors to control the opening or closing of each channel through the strobe switch, and select the channel to be called through the selector .

For example, when two display control systems are required for real-time image processing, and the respective channel configurations in each display control system, including channel functions and channel quantities, can already meet the display requirements, the selector can be configured to select local Channel, so that each display control system uses its own channel and function to process and output the input image data in real time; when the application scenario requires two display control systems for real-time image processing, and there is a channel configuration in a display control system If the display requirements cannot be met, one or more channels and functions are called to other display control systems with free channels through the channel selection switch and selector, and the input image data is processed in real time and output to the corresponding display. For example, when the two layers to be processed by the display control system 1 need to perform special format conversion, rotation, scaling, etc. of the image, and the display control system 2 only needs to do simple display or no display, in addition to using the display system control In addition to channel (layer) 1 in system 1 performing special format conversion, rotation, and scaling on a layer, channel (layer) 1 in display system control system 2 can also be used to perform special format conversion on another channel (layer). Format conversion or processing such as rotation and scaling.

It is worth noting that in this implementation example, the selection of the call channel is realized through the strobe switch and the selector, which is only one of the implementation methods that are easily thought of by those skilled in the art. Of course, other implementation methods can also be used to realize The selection of the calling channel is not intended to limit the present invention.

In the present invention, in the multi-display control system, different channel functions are configured for each channel of the display system. When the channel configuration of any display control system cannot meet the current image processing requirements, other channels are called according to the channel configuration. For the idle channels in the display control system, since different channels can be configured with different functions, the duplication of channel functions is reduced, and the functions of the channels are simplified. Therefore, the chip area occupied by the display control system is reduced, and the power consumption of the system is reduced. Through the call mechanism of the channel, the utilization rate of resources is improved, so that the requirement of multiple display devices to display different contents at the same time is realized with a smaller chip area and power consumption, and a higher resource utilization rate.
