Introduction
Skyvision DS-4002MDI matrix decode board is the key product to
build digital video matrix and network matrix. It can be used for
decode H.264 streams compressed by Skyvision DS-4000HCI, DS-8000HCI, DS-8002A(ATM/POS), DS-8000SI. It is a
bridge between digital and analog system, and strongly support
concentrative digital surveillance solution.
Decode function
1. Each DS4002MDI can realize 4 channels QCIF,CIF,2CIF or 3
channels DCIF, 2 channel 4CIF real time decoding.
2. Audio output: 2 channels, can choose any 2 of the 4 decoding
channels.
3. Video output: 2 channels, each video output can be max divided
into 16 windows.
4. Audio preview: each DS4002MDI support 1 channel audio preview
output.
5. Software: from version3.0 SDK, Tsingvision provide the support
to DS-4002MDI.
6. Support the mixed insert of HCI series board and MDI board in
one PC.
7 Within one SDK, it can simultaneously support HCI and MDI board.
8. At present one PC can max support 16 pieces of DS4002MDI board,
that is to say 64-channel decoding and 32-channel video output.
9. Basic decoding capability (the possible DSP resources occupied
when decoding one channel):
CIF: 12% (512Kb); 16% (2Mb)
2CIF: 30% (1Mb)
DCIF: 28% (768Kb)
4CIF: 50% (1Mb); 60% (3Mb)
Explanation: the test file above is the setable image under fixed
bitrate. At present the further optimization is on process, the
performance will be improved in the afterward versions.
