High-def video interface has JPEG2000 compression

LONDON — Curtiss-Wright Controls Embedded Computing has announced the XMC-280 interface for high-definition video with JPEG2000 compression.

The XMC-280 provides an open standards-based solution for capturing, compressing, decompressing and displaying two channels of video up to 1080p and 1920×1200 resolutions. Designed for demanding military video applications, the XMC-280 facilitates the design of systems that require the distribution or recording of video such as those in situational awareness applications.

In real-time embedded systems JPEG2000 offers better quality than MPEG at higher compression ratios and because each frame is compressed individually there is no dependence on preceding or subsequent frames. This frame-by-frame compression results in lower latency and greater resistance to errors in transmission.

Using the XMC-280 multiple channels of high-definition video can be distributed over standard gigabit Ethernet networks in excellent quality and with minimal latency. Details are retained at 50:1 compression at which eight 1080p60 channel could be transmitted over a single gigabit Ethernet.

The XMC-280 is supported on Intel x86 and Power PC hosts under Windows, Linux and VxWorks and as an standard XMC-format module it can be used in a variety of system types such as PCs and embedded rack-mount displays.

The XMC-280 has two video inputs (each can be Digital DVI, Analogue RGB or PAL/NTSC composite) each up to 1920×1200 at 60Hz, and two DVI-D digital outputs. Captured video is compressed using a FPGA-based JPEG2000 algorithm or transmitted over PCIe interface uncompressed. It also provides two stereo channels (or four mono channels) of audio input/output (16-bit 48kHz, WAV and PCM encoding) and JPEG2000 ISO/IEC15444-1 image compression standard (9/7 irreversible wavelet compression) providing visually lossless compression at ratios in excess of 10:1.

It provides support for both 4:2:2 and 4:4:4 video coding and has a four-lane PCIe 1.1 interface optimized to provide in excess of 500MB/s in each direction. It is available at CWCEC Level 0 environmental specification, for rugged air- or conduction-cooled versions contact the design center.
