IPX-JPHD: JPEG 2000 HD Encoder family

IP Vendor: 
intoPIX s.a.
IP Target Vendor: 
Xilinx
IP Type: 
Design
IP Category: 
Audio, Video and Image Processing
IP Supported FPGA Device: 
Virtex-5 FXT
Virtex-5 LX
Virtex-5 LXT
Virtex-5 SXT
IP Description: 

The IPX-JPHD is a high
quality and cost effective family of FPGA based JPEG 2000 encoders 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.
