8.4.14.2 Example 2
The DS90UB964-Q1 is receiving data from cameras attached to each port. Each port is sending a video stream
using VC-ID of 0. The DS90UB964-Q1 can be configured to re-map the incoming VC-IDs and distribute to
different CSI Transmitters. This implementation maps incoming VC-ID of 0 for RX Port 0, VC-ID of 1 for RX Port
1, VC-ID of 0 for RX Port 2, and VC-ID of 1 for RX Port 3. RX Ports 0 and 1 are assigned to CSI Transmitter 0
which RX Ports 2 and 3 are assigned to CSI Transmitter 1.
