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
