In general, the encoder user interface will change as a function of the parameter selections made,
to remove illegal parameter combinations.
Selections made in any of the encoder configuration screens do not take effect until the Apply
button is pressed. If you wish to discard the changes made to the user interface, press the Cancel
button. The Apply/Cancel buttons are present in all the tabs and will be grayed out until
changes are made. At any given point in time, the currently running encoder configuration can
be inspected in the Encoder Statistics Tab, described later in this document.
Video Input Auto-Detection
The 9223 can be set to auto-detect the video input signal, and self-configure for the incoming
resolution and frame rate. This feature allows the encoder to operate in situations where the
video signal can change over time (for example, at the output of a video switch). The 9223 is
even capable of automatically recognizing whether a signal is SDI or composite, and the video
standard for composite signals.
The following points should be considered when using video input auto-detection:
• The available output scaling options are limited, since some options are specific to some
input resolutions.
• If the encoder is not licensed for a given configuration, it will stop encoding if the input
video signal switches to a value that requires this configuration. For example, an SD
encoder configured to output the same resolution as the input will stop if the input signal
switches to HD.
• If the encoder is configured with auto-detection and SDI embedded audio, it will fall
back to analog audio if it detects a composite video signal. If your input can switch
between SDI and composite, either use analog audio for all signals, or make sure that the
corresponding analog audio signal is present at the encoder audio inputs when the video
is a composite signal.
