    Custom Input and Output Modes For most applications, the source input of the VNE 250 is set to auto mode. This enables the encoder to detect the electrical and timing characteristics of the input signal and determine the exact source type. It then invokes the appropriate input parameters for optimum processing of that source.

    (RGB/YPrPb) (see figure on the previous page) — Because of the Color space • similarity between analog RGsB (sync on green) and component YPrPb signals, sources using these formats may not auto-detect correctly. RGsB and YPrPb sources have different color spaces and if the wrong setup is applied the resulting image, although stable, has a red or green color cast.

    Custom Output Modes The decoder tab allows you to create custom video output formats for displaying Format decoded video data streams.
