PRODUCTION DATA
During Basic Synchronized Forwarding each forwarded frame is an independent CSI-2 video frame including FrameStart (FS), video lines, and FrameEnd (FE) packets. Each forwarded stream may have a unique VC ID. If the forwarded streams do not have a unique VC-ID, the receiving process may use the frame order to differentiate the video stream packets.
The forwarding engine attempts to send the video synchronized. If synchronization fails, the CSI-2 transmitter stops forwarding packets and attempts to restart sending synchronized video at the next FS indication. Packets are discarded as long as the forwarding engine is unable to send the synchronized video.
Example Synchronized traffic to CSI-2 Transmit port at start of frame:
FS0 – FS1 – FS2 – FS3 – S0L1 – S1L1 – S2L1 – S3L1 – S0L2 – S1L2 – S2L2 – S3L2 – S0L3 …
Example Synchronized traffic to CSI-2 Transmit port at end of frame:
... S0LN – S1LN – S2LN – S3LN – FE0 – FE1 – FE2 – FE3
Notes:
Each packet includes the virtual channel ID assigned to receive port for each sensor.
