3.7.25 Automatic Video Input Detection and Configuration
The AVP 4000 is capable of automatically detecting the format of the video and
automatically configuring the encode to match. The AVP 4000 can be configured to
detect between HD input standards only or between SD and HD input standards.
3.7.25.1 Selection of Automatic Video Input Detection and Configuration
3.7.25.1.1 Encode
Set up an encoding service as documented in section 3.7.6 How to Configure the
Chassis for Multi-screen Functionality. On the Service Configuration > Outputs >
<service> > Video component, select the Input tab on the Properties widget. The
parameter Input Detection is presented with five options: Off, HD 25/50Hz, HD
29.97/59.94Hz, SD/HD 25/50Hz, SD/HD 29.97/59.94Hz.
Selecting the Off option allows you to explicitly set the Video Input Format. When
Off option is selected, auto detection is disabled and the user must select the valid
Video Input Format manually.
Figure 3.50 Encoding: Manual Input Format
If HD 25/50Hz is selected, the AVP 4000 will automatically select an HD vertical
resolution based on the incoming video. The Detected Video Standard gives
feedback to the user on what vertical resolution has been detected by the
AVP 4000. If the detected standard is an HD format with a frame rate of either 25Hz
or 50Hz, the Video Input Format is automatically set to that detected standard.
The same applies for HD 29.97/59.94Hz.
