Brief Introduction of
TT-4008H
card
|
|
TT-4008H
compression board is a
professional digital security product, which adopts most
advanced H.264 video compression algorithm and OggVorbis
audio compression technology. Compared with TT-400xM and
TT-400xH board.
TT-4008H
can support up to 16
channels in one board (TT-4016HCI), compress video with
CIF/2CIF/DCIF/4CIF resolution and preview with 4CIF. Newly
designed PCB of the card more compact and steady and
compatible SDK interface makes development faster and
easier.
TT-4008H
board uses fully optimized algorithm based on DSP technology
to implement video & audio real-time encoding, active video
& audio preview and motion detection, etc. Video image is
directly transmitted from board to display frame buffer and
compressed stream is also directly sent to host's memory.
The whole transmit doesn¨t need any intervention of host
computer processor, saving resources of host computer¨s
processor greatly. One Personal computer can support up to
64 channels Video and audio input, parameters of each
channel can be set independently and will not affect each
other.
TT-4008H
compression board supports Windows 2000/XP/2003 and Linux
operating system at present, provides demonstration
application with its source code, the whole SDK development
package including system SDK, player SDK, networks SDK,
media Player plug in, etc, and also provides technical
support and good after- sale service.

Merits
of Adopting TT H.264 Compression Board
H.264
encoding has the advantage of high image quality, low
bitrate and low storage requirement, especially suitable for
digital video security. TT H.264 compression board is the
state-of-the-art video / audio compression board, which
adopts H.264 ACE (ADVANCED CODE EFFICIENCY). Compared with
other compression board, its advantage embodies the
following aspects:
Save storage
space
TT board compression ratio is higher than those that adopt
MPEG-1 or other standard. Given the same capacity of hard
disk, TT board lead to longer recording time, thus reduces
storage costs and maintenance expenses and improves
systematic reliability.
Excellent image quality
TT board adopts variable bitrate coding.
It assures constant image quality to
different scene and motion picture. Even violent motion
cannot bring
the mosaic phenomenon. TT board supports real time preview
without wobble or
time delay.
Preeminent
characters of network transmission
TT
board adjust parameter dynamically, which is suitable to
assure excellent and
fluent image quality in network transmission. It supports
4CIF, DCIF, 2CIF, CIF,
QCIF coding, variable bitrate and variable frame rate. This
is more suitable
for narrowband transmission, for instance, through PSTN, ISDN, DDN, etc.
Convenient
control
TT
board¨s parameter, such as image quality, frame rate, and
sensitive tolerance
of motion detection can be adjusted when encoding. It can
capture original image. Actively setting parameter is
significant in video security.
Flexible and reliable motion detection
TT board
adopts most advanced motion detecting technology whose
analytical precision can be adjusted dynamically. It can not
only detect micro-motion but also throw away misinformation.
Reliable motion detection and video setting reduce storage
requirement. The whole detecting procedure is completely
done on board. Motion detection is completely independent
from compression. It can detect both fast and slow motion.
Convenient video
overlay function
TT board supports
flexible title overlay function. It can overlap time on
active video
with transparent processing. Its location can be adjusted
conveniently.
Outstanding
stability and sustainability
TT
board adopts encoding algorithm, SDK function and decoding
software, which
are specially designed for digital video security. All of
these make TT board reliable
and stable
