Large and high resolution display of images on a large screen using multiple DVI connections

The next generation Medical systems will be equipped with very large display screen (>56") which will have a high native pixel resolution (>8 Mega Pixels). The content that is displayed on the large screen is taken from several (computer) sources, that deliver the image content via a Digital Visual Interface (DVI). These DVI sources are mixed within a DVI mixer device, the mixed output of this device is connected with the large display screen.

In order to get the optimal image quality within the system, it is desired to display the acquired (medical) images in its native pixel resolution (i.e. no image scaling). Within today's medical system with advanced flat dynamic X-ray detector(s), images up-to 2560x1920 pixels can be acquired. However, the current generation DVI mixers only support single link DVI interfaces, which limits the image resolution to ~1920x1200 pixels.

To overcome this problem the invention proposes:
Instead of using a dual link DVI interface, we use two single link DVI interfaces. The high resolution image is spatially divided into two image parts of lower resolution. Each part of the image is packed into a standard video format and is transmitted over the single DVI link toward the DVI mixer device.

The DVI mixer device will select relevant parts of the image data transmitted by the separate DVI links. The mixer will reconstruct the original image from...
