VIP: Double a video stream

[Altera_Forum]

Hi, 

 I want to double a video stream (created with the clocked video in function) in order to put them out with 2 resolutions (resolution A on DVI-out A, resolution B on DVI-out B).   Is there a function to split the avalon stream into two equal streams (to use 2 different scalers and 2 different clocked video outputs).   Thanks a lot.   Best regards   Mark   Hardware: Altera cyclone III Dev Board Bitec Quad Video daughter card Bitec HSMC DVI-Board   QuartusII 8.1 & NiosII 8.1

The Color Plane Sequencer function can be used to split/duplicate a video stream. Please be aware that you might have to add a double buffering function on one or both of the datapaths downstream of the color plane sequencer because back-pressure on one side would starve the other side.

You could also create two complete data paths (two clocked inputs) and feed them both with the video input. You'll have to see what gives you the lowest resource usage.
