The PMC-281
provides real-time MPEG4 Part 10/H.264
compression of video channels
supporting resolutions up to 1920×1080 pixels. It is ideal
for video distribution and recording applications, where
high-compression ratios allow multiple channels of highdefinition
video to be stored on disks and solid-state media
and carried on digital networks.
As a PMC-format mezzanine card, the PMC-281 brings
high-performance video compression to a wide variety
of system architectures including VPX, VME, CompactPCI
(CPCI) and PCI Express® (PCIe).
The PMC-281 uses an ASIC for low power consumption
making it ideal for deployment in harsh environments,
in platforms as diverse as naval, land vehicle, fast jet,
helicopters and UAV.
The two channels of the PMC-281 can be configured for
compression or decompression. Each input or output can be
independently configured to support single-link DVI, RGB or
The PMC-281 loop-through capability is especially useful in
recording applications: the PMC-281 can be inserted into
the video path so that during compression input video is
routed both to the video decoder and to the output.
MPEG4 Part 10/H.264 compression is widely used in
commercial and defense applications and users can choose
from a wide variety of software decoders as an alternative
to the hardware-accelerated decoding of the PMC-281.
