## Title
Reducing the number of scaling engines used in a display controller to display a plurality of images on a screen

## Abstract

Methods and apparatuses to reduce the number of scaling engines used in a display controller that displays image content associated with a plurality of image sources on a screen are provided. A first multiplexer may receive image content from a plurality of storage devices, and select first image content from one of the plurality of image sources. A first scaling engine may process the selected first image content, wherein a plurality of multiplexers can receives an output of the first scaling engine and the image content from the plurality of storage devices, respectively. Each one of the plurality of multiplexers may output either the image content input to the multiplexer or the output of the first scaling engine depending on which image content was scaled by the first scaling engine. Additionally, a plurality of post-processors may perform additional post-processing on the output of the plurality of multiplexer, respectively.

## Background
BACKGROUND
Existing video systems can display various types of image content (such as video and graphics) on a specified portion of a screen at different resolutions and sizes. In existing video systems that use scaling engines to scale multiple images, videos and/or graphics for display on a screen, each image processing plane in the display controller may have a dedicated a scaling engine. However, having a scaling engine for each image processing plane in a display controller can be very costly and inefficient. Furthermore, a scaling engine for an image processing plane can be designed to process only video or graphics data, which may limit which image processing plane can be used to process a particular image content source. Accordingly, conventional video systems may be relatively inflexible.

The video system 100 can include memory 105 to store image content associated with a plurality of image sources to be displayed on a screen 115 and a video display controller 110 to scale the image content associated with the plurality of image sources for display on the screen 115.
FIG. 2 illustrates an example video display controller 200 for the video system 100 of FIG. 1. The display controller 200 and its associated processes may be implemented in configurable logic such as, for example, programmable logic arrays (PLAs), field programmable gate arrays (FPGAs), complex programmable logic devices (CPLDs), in fixed-functionality logic hardware using circuit technology such as, for example, application specific integrated circuit (ASIC), complementary metal oxide semiconductor (CMOS) or transistor-transistor logic (TTL) technology, or any combination thereof.
In particular, the video display controller 200 may include a plurality of image processing planes 205(1), 205(2), . . . , 205(N), wherein each illustrated image processing plane 205(i), i=1, . . . , N, includes a buffer 210(i) to hold image content. The image content stored in the buffer 210(i) may be read from a memory such as the memory 105 (FIG. 1), already discussed.
A first multiplexer 215 may receive the image content from the plurality of image processing planes 205(1), 205(2), . . . , 205(N) and may select which image content to be processed by a scaling engine 220.
Each image processing plane 205(i) may further include a second multiplexer 225(i) to receive the image content stored in the buffer 210(i) and the output of the scaling engine 220. The second multiplexer 225(i) may output either the image content stored in the buffer 210(i) or the output of the scaling engine 220 depending on which image processing plane, i, was processed by the first multiplexer 215.
Each image processing plane 205(i) may further include a post-processor 230(i) to perform additional post-processing on the image content stored in buffer 210(i).
The illustrated display controller also includes a blender 235 that receives the outputs of the post-processors 230(i), i=1, . . . N and merges the image content associated with the plurality of image sources for display on a screen such as the screen 115 (FIG. 1), already discussed. In some implementations, the output of the blender 235 may be input to the first multiplexer 215 to be selected to be processed by the scaling engine 220. In this case, the output of the scaling engine 220 is used for display on a screen.
By providing the example video display controller 200 of FIG. 2, the number of scaling engines used in a display controller to display image content associated with a plurality of image sources on a screen may be reduced.
