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.
