Overview of Edge-Blending Technology

is usually performed by a seamless switching system such as the Encore Video

Processor, or BlendPRO-II.

Reformatting allows the resultant images to provide seamless switching,

integration of picture-in-picture (PIP) video and keying features. Note that the

input image can be effectively spread to cover multiple screens, however, the

inherent resolution of the output image remains that of the source material,

1920x1080 pixels.

• Use Of Multi-Head Graphics Boards

Standard multi-head graphics boards can be used to directly generate image data

to drive multiple screens. In this case, the computer generates one very high-

resolution image and the image is output by multiple graphics heads. The

inherent resolution of the output image is limited only by the processing power of

the multi-head graphics board. Image resolutions with up to 10,000 pixels of

horizontal resolution can be achieved with current technology.
