Data Sheet
H.264 / MPEG4-AVC Encoder
When it comes to Video Compression, no other board comes
close the video quality and compression ratio of the DS-4004H
from DSP Research, Inc.
The codec yields higher picture quality and about 40% lower
bit rate than is possible with MPEG4-ASP, and even greater
improvements when compared to MPEG4-SP or MPEG2. The
board is the ultimate, most efficient and flexible in CIF video
compression today.
The new H.264 / MPEG-AVC standard
The new H.264 / MPEG4-AVC video compression standard is
the first to be ratified by both the ISO/IEC and ITU-T. It raises
the bar considerably compared to MPEG4-ASP and yields better picture quality while significantly lowering the bit rate. This
allows lower overall system cost and enables new video applications. H.264 / MPEG4-AVC is considered the greatest achievement in video compression in the past 10 years and is already
finding its way into many mainstream video applications.
Software Upgradable
The many features and flexibility of the DS-4004H along with
the power of H.264 / MPEG-AVC make this board the perfect
choice for security and surveillance applications as well as many
other video tasks. Come see why people are switching to the DS4004H. 
The DS-4004H board from DSP Research, Inc. is the very first
implementation of this new exciting standard. It is the result of
intense research and development in video compression over the
last 10 years.
The compression codec in DS-4004H is implemented in software
running on the optimized media processors. This means that it is
possible to upgrade the codec through new firmware without any
hardware changes.
The Ideal Video Encoding Board
The DS-4004H uses four media processors, each with its own
video input, VIP (Video Input Processor), memory and PCI
interface. On each processor runs our heavily optimized H.264 /
MPEG4-AVC codec.
