Decoding

During decompression, the data enters through the memory

 

port on the MJPEG FPGA chip, and passes through the JPEG

 

processor, the Color Space Converter, and finally exits through

 

the Matrox Meteor-II grab port.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Host

Due to a hardware limitation, the MJPEG module on the Matrox Meteor-II /Standard cannot decompress JPEG (non-interlaced) compressed data; decompression of JPEG data will be performed by the Host.
