Encoding JPEG
Decoding
During JPEG (non-interlaced) compression, the baseboard
grabs an entire frame of data. This data enters the module
through the memory port on the MJPEG FPGA chip and passes
through the Color Space Converter. From there, JPEG
compression follows the same path as MJPEG compression.
Compressing an archived video stream is supported under
JPEG compression.
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.
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.
