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.

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 want to use less than 9 channels, use “Video Matrix Function” to make dual stream encoding. The “Video Matrix Function” is far more powerful than “Real Channel / Virtual Channel”, Because the “Video Matrix Function” can generate 2 encoded stream with different picture resolution. Please use “Real Channel / Virtual Channel”, if you use more than 8 channels and want to make dual stream. If you use SOLO6010-4, please read “About SOLO6010-4 Video Muxing and Encoding.ppt” document.

  15. 1-4. End encoding 1 / 1 “End encoding” Request “End encoding” OK N : Channel number

  16. 1-5. SOLO6010 SDRAM and register status during encoding 1 / 9 The “VE_MPEG4_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”, “MPEG4 Code Address Offset”. Most important information is “MPEG4 Code Address Offset”. This is the position of encoded frame in MPEG4 code buffer (SOLO6010 SDRAM) The “VE_STATUS11” register point to the index of the queue register (VE_MPEG4_QUE N) which has information about just encoded frame. (Please refer to 1-3. Get encoded MPEG4 stream data from SOLO6010) 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 SOLO6010 frame header (64 byte) is just copy of these register. SOLO6010 frame header consist of 48 byte MPEG4 video Encoder status register (12 registers) and 16 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_MPEG4_QUE N” register.

  27. 2-2. Picture Size (Picture Resolution) 1 / 1 The picture size of virtual channel is same as real channel. Thus CAP_SCALE_E (0x0480 +(4 *N)) register is a flag register about virtual channel encoding on /off. You cannot change “Picture Size” while encoding. “Picture Size” can be set only when before encoding.

  28. 2-3. FPS (Frames per second) 1 / 1 CAP_INTERVAL is same as Skipped Frame Number. CAP_INTERVAL == 0 means no frame is skipped. (NTSC D1 30 frames, PAL D1 25 frames, …) CAP_INTERVAL == 1 means 1 frame is skipped. (Every second frame is encoded.) CAP_INTERVAL == 2 means 2 frame is skipped. (Every third frame is encoded.) … D1 is frame picture, the max. frame rate is 30 (25). And other picture size (Half D1, CIF) is field picture, the max. frame rate is 60 (50). CAP_INTERVAL for Real Channel CAP_INTERVAL_E for Virtual Channel You can change “FPS” while encoding.

  29. 2-4. Picture Quality (QP) 1 / 1 You can change “Picture Quality” while encoding.
