Plasma display S-video problem

Extron has encountered a problem with the S-video output by some video conference codecs, when it is switched using a CrossPoint Plus. Some codecs change the DC offset on the chrominance (C) so that it is very different from the level on the luminance (Y). This can cause a plasma display to come up in the wrong size mode.

With the matrix switcher taken out of the system, the plasma works fine. It looks like a Extron problem, but it is not. The matrix switcher boosts the bad codec output, which makes the plasma go to the wrong setting.

Solution: Try placing an Extron video DC block adapter, part #26-495-01, on the luminance (Y) input to the switcher from the codec.

Worksheets

Rather than trying to remember the configuration for each preset, use worksheets to record this information. Make copies of the blank worksheets on page 3-19 and use one for each preset configuration. The forms accommodate all of the CrossPoint Plus models. Cross off all unused or inactive inputs and outputs. Use different colors for video and audio.

Worksheet example 1: Entering system equipment

Figure 3-21 shows a worksheet for a CrossPoint Plus 128 HVA in a fictional organization with the system hardware annotated. Inputs 10 and 11 and output 7 have no connections in this organization, so they have been crossed out on the worksheet. On this example, preset 3 is used for the weekly status meeting. Choose your own method of notation.
