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 signal.
This also has the advantage of changing the input setup automatically, without any user
intervention, if the input source changes to another source type (for example, if the input is
derived from a source switcher).
While the auto mode works with most standard video and graphics standards, there are
circumstances (particularly with analog sources) in which additional fine‑tuning may be
required. For example, when the source:
z
Is an RGsB (sync on green) or YPrPb source type.
z
Has Macrovision copy protection.
z
Does not have a completely standard signal format.
In extreme circumstances, it may even be necessary to
(see page 80). For example, when a source:
z
is completely non‑standard.
z
has a poor quality signal.
NOTE: The advanced source setup procedures described here are only required for
analog sources. For digital sources, the input mode should always be set to auto.
