The video matrix is a input switcher between camera input and video channel.
You can assign any of camera input to any of video channel by setting video matrix. And you can assign 1 camera input to multiple video channels.
There are some examples of video matrix setting in the next pages.

“Video Matrix Function” and “Real Channel / Virtual Channel” are independent of each other.
The “Video Matrix Function” reside between camera inputs and video channels.
And the “Real Channel / Virtual Channel” reside between video channels and encoded streams.
You can use video matrix function as virtual channel.
If you use SOLO6110-4, please read “About SOLO6110-4 Video Muxing and Encoding.ppt” document.

The “VE_H264_QUE N” registers save encoded frame information.
The number of these register is 16. This means that unless you miss 16 or more interrupt, you can get all encoded frame.
This register has information about “Motion Flag”, “VOP Type”, “Channel”, “H.264 Code Address Offset”.
Most important information is “H.264 Code Address Offset”. This is the position of encoded frame in H.264 code buffer (SOLO6110 SDRAM)
The “VE_STATUS11” register point to the index of the queue register (VE_H264_QUE N) which has information about just encoded frame.
(Please refer to 1-3. Get encoded H.264 stream data from SOLO6110)
The “VE_STATUS0 ~ VE_STATUS11” register always have information of just encoded frame. But you need not check this register value except
“VE_STATUS11” because SOLO6110 frame header (64 byte) is just copy of these register. SOLO6110 frame header consist of 52 byte H.264 video
Encoder status register (13 registers) and 12 byte garbage.
Thus the only information you need is position and size of encoded frame. This information can be taken from “VE_STATUS11” and
“VE_H264_QUE N” register.

In PAL video system,
size of OSD image is less than size of PAL image (704 x 576).
Thus, if you want to display OSD at bottom line of PAL image,
you should change encoder OSD position value.
In NTSC video system, there is no problem in encoder OSD displaying.
