IP Description: 

The IPX-JPHD is a high
quality and cost effective family of FPGA based JPEG 2000 and decoders
designed to meet the requirements of high data rate processing in broadcast
Acquisition, Storage and Contribution. Based on a single chip, the exceptionally
flexible IPX-JPHD family supports variable compression ratio’s up
to Lossless and can be adapted to any image resolution up to HD (1920
x 1080).

The powerful IPX-JPHD
modules also provide a compact and reliable solution to broadcasters
need for Multi-channel operation through a unique single chip design
that enables up to four HD channels to be streamed simultaneously at
a total frame rate of 120fps.

Purpose designed for
the Xilinx® FPGA the IPX-JPHD family is a no compromise solution that
takes full advantage of the benefits of the state-of-the-art Virtex-5â„¢
platform including easy connection to HD-SDI, SDI, SDTI, ASI, PCI-Express®
and Gigabit Ethernet broadcast and system interfaces.

The IPX-JPHD Decoder
module also takes full advantage of the flexibility, compactness and
interfacing capabilities of the Xilinx Virtex-5 technology.

IPX-JPHD is ideally suited
to real-time Contribution requiring the transport of live video material
between different locations, including content exchanges and live events
coverage between studio or stadium and production house, with the minimum
transport delay.

As efficient video storage
becomes increasingly important JPEG 2000 compression offers an ideal
solution. While servers must be capable of ingesting and storing multiple
video streams in real time it is also essential for editing that storage
systems use the appropriate Lossy compression to avoid the progressive
reduction of quality through successive compression and decompression
operations. Unlike MPEG compression-decompression (which introduces
additional degradation at each step) a JPEG 2000 file maintains the
image quality corresponding to the highest compression rate of the chain.
