VESA Completes Specifications For New Multiple Projector Common Data Interchange Standard (MPCDI)
The Video Electronics Standards Association (VESA) today announced the publication of the VESA Multiple Projection Common Data Interchange (MPCDI) Standard. The MPCDI standard was developed by VESA's Multi-Projector Automatic Calibration (MPAC) Task Group to create a standard data format for projection calibration systems to communicate with devices in a multi-display configuration. The standard allows multi-projector systems to generate the data needed to combine individual display components into a single, seamless image. These systems are able to produce data that can be consumed by a variety of devices, other programs, and displays without necessitating individual integration efforts. Rather than having to worry about integrating with multiple systems the new piece of hardware and software can be easily integrated with the standard.
“Industries such as corporations, education, information management and telecommunication increasing their use of projectors to display information in a broader form, the MPCDI standard will be vital for the longevity of currently implemented projection systems,” said Daniel Baker, assistant producer, Creative Technology Group, Walt Disney Imagineering. “In any market, there are constantly changing technologies with new capabilities. Upgrading and replacing components means new custom software. With a common standard such as MPCDI, existing systems are supported as components can be replaced interchangeably, therefore conserving costs when replacing and upgrading systems.”
VESA's MPCDI standard defines how multiple displays, typically projectors, are combined to create a single seamless display. Currently, multiple projector systems require the integration of many different components. With custom multiple-projector displays, this can require combining projectors, image generators, warping boxes, media servers, splitters, and distribution amplifiers.
