Figure 5–15. Example of Combining Color Patterns
The Color Plane Sequencer also allows the splitting of a single Avalon-ST Video input
stream into two Avalon-ST Video output streams. In this mode of operation, the color
patterns of video data packets on the output streams can be arranged in a user defined
way using any of the color planes of the input color pattern.
The color planes of the input color pattern are available for use on either, both, or
neither of the outputs. This allows for splitting of video data packets, duplication of
video data packets, or a mix of splitting and duplication. The output color patterns are
independent of each other, so the arrangement of one output stream's color pattern
places no limitation on the arrangement of the other output stream's color pattern.
Packets from input stream 0 (port din0) and input stream 1 (port din1) forwarded,
input stream 0 packets being transmitted last. (The last control packet received is
the one an Avalon-ST Video compliant MegaCore function uses.)
Packets from input stream 0 forwarded, packets from input stream 1 dropped.
Packets from input stream 1 forwarded, packets from input stream 0 dropped.
