Line Y for Camera X video frame
CxLN
Last line for Camera X video frame
C0L1,C1L1,C2L1,C3L1 indicates concatenation of the first video line from each camera 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 camera port being forwarded.
Lines are concatenated on a byte basis without padding between video line data.
