IP based Matrix Video Wall Control System HDMI Input/Output Node

 DTB-II is endpoint node of AVCIT's 2nd generation of IP based system, it collects video signals and transmits IP streaming over Ethernet, it is both the input node and output node,2 nodes are just 1, High lighting feature of 2nd generation of IP based system is
live video preview and control,users can preview all videos,simply drag any video to any displays, get a experience of "what you see is what you get“ It is with style of a standard wall plate, more compact, easy for installation.

It combines the feature oif

1. video wall controller
2. Multi-viewer
3. HD matrix switch-transmit, HDMI+IR+RS232
4. Central controller
5. Video conference

1. Each node have 1 channel bi-directional RS232, 3 channel bi-directional I/O, 3 channel bi-directional IR
2. Bi-directional IR/RS232, Live status of volume,dimming and etc. will be dislayed on
touch panels, even the operation is from physical button

3. Bi-directional transmission of video, make sure status of all touch panels to be
synchronous
4. H.264 Coding
5. Works well with IP camera, live video from IP camera to be displayed on both Pad and video wall
6. No server required, input node can also be output node at the same time, each node has independent IP, no conflict
7. Max 16 windows overlapping on each physical displays
8. Permission management feature, Administrator can preset permission for unlimited sub-user
9. Live video preview feature, users can preview all videos, simply drag any video to any displays, get a experience of "what you see is what you get”

10. Auto-switching among multiple Data Center, hot-backup feature
11. Video Wall Controller feature, video can be zoomed in/out and overlapped anywhere at any sizes
12. Timing power on/off feature
13. Auto backup on clouds and recovery feature
14. Independent audio transmission and output, a) Each node transmit audio and video transmission separately. b) audio output of each node can be from any input audio,either homologous or not; c) each units have analog audio input interface, audio can
be de-embedding audio for HDMI or simply to be an analog audio input; 2 composite video output for live monitoring
15. Resolution supports 800*600 to 1920*1080 60Hz
16. Transmitting distance 100m, over CAT5e/6
17. Unlimited Scalability, Simply add one node per source or per new display
18. Support IOS / win7 / Android and other operating systems
