Barco DCPB-2120 User manual

The DCPB-2120 is a PCI-Express acceleration board for performing JPEG 2000
compression. It can process one stream of 1080p60, or multiple streams at lower
resolutions, in real time.
Featuring a unique rate allocation module, the DCPB-2120 can encode untiled
images with resolutions up to 1080p. Moreover, its programmable configuration
in constant bitrate or constant quality modes allows the user to generate high-
quality JPEG 2000 codestreams at various bitrates.
Its compactness makes the DCPB-2120 an excellent alternative to PC clusters,
offering real-time encoding capability in a PCIe form factor. In addition, it is built on
FPGA technology, which offers the advantages of flexibility and upgradeability.
The DCPB-2120 can be used for various broadcast or other applications, including
Acquisition, Storage, Archiving, Production and Contribution.
