Setting Up the Video Input

To Set Up the Video Input
Proceed as follows to set up the Video Input:
1. From the user interface of the D9054 HD Encoder, click the Video tab.
2. Select the Video Format.
You may select 1080i/25 Hz, 1080i/29.97 Hz, 720p/50 Hz or 720p/59.94 Hz
formats.
3. Set the Frame Synchronization.
You may select Off, Internal Clock or External Reference. The default is Off.
When Off is selected, the internal frame synchronizer is bypassed. This provides
the best lip sync as the internal clock is locked to the incoming video signal.
When Internal Clock is selected, an internal reference is used as the encoding
reference. The internal clock should be used when the encoder is connected to
an unstable video source.
If the encoder is configured for an external reference, it will use an SD analog
video signal to reference its encoding reference. If the encoder is configured to
pass Dolby AC3, AAC or Dolby E/linear pre-encoded audio, it is mandatory
that the frame synchronizer be set to Off or that the external reference is locked
to the incoming video source.
4. Click Apply.
