7.4.25.5 Line-Concatenated CSI-2 Forwarding

In synchronized forwarding, the forwarding engine may be programmed to merge video frames from multiple sources into a single video frame by concatenating video lines. Each of the sensors for each RX carry different data streams that get concatenated into one CSI-2 stream. For example, if forwarding from all four input ports, only one FS, an FE packet is sent for each video frame. The synchronization packets for the other 3 ports are dropped. In addition, the video lines from each sensor are combined into a single line. The controller must separate the single video line into the separate components based on position within the concatenated video line.

Example Synchronized traffic to CSI-2 Transmit port at start of frame:

FS0 – S0L1,S1L1,S2L1,S3L1 – S0L2,S1L2,S2L2,S3L2 – S0L3,S1L3,S2L3,S3L3 …

Example Synchronized traffic to CSI-2 Transmit port at end of frame:

... S0LN,S1LN,S2LN,S3LN – FE0

Notes:

    FSxFrameStart for Sensor X
    FExFrameEnd for Sensor X
    SxLyLine Y for Sensor X video frame
    SxLNLast line for Sensor X video frame

S0L1,S1L1,S2L1,S3L1 indicates concatenation of the first video line from each sensor into a single video line. This packet has a modified header and footer that matches the concatenated line data.

Packets would have the same VC-ID, based on the VC-ID for the lowest number sensor port being forwarded.

Lines are concatenated on a byte basis without padding between video line data.
