8995UPC/DNC/UDX — Instruction Manual 27
Configuration
• Auto Freeze – when Auto Freeze is enabled on a channel, the output
will automatically freeze on the last valid field when the input signal is
lost on the input.
• A Manual freeze can be performed at any time with the following two
choices:
• Frame
• Field
Note A field freeze provides less resolution and no motion artifacts in the output.
In frame mode, the resolution is higher since both fields are present, but the
presentation of the two fields can cause motion artifacts.
Signal Conversion
The 8995UDX module performs three main video conversion functions:
• Up Conversion – allows an SD signal input to be converted to an HD
output signal in the same time domain (480i/59.94 to 1080i/59.94 or
576i/50 to 1080i/50 for example).
• Down Conversion – allows an HD signal input to be converted to an SD
output signal in the same time domain (1080i/59.94 to 480i/59.94 or
1080i/50 to 576i/50 for example).
• Cross Conversion – allows an HD signal input to be cross converted
between progressive signal types and interlaced signal types in the
same time domain (720p/59.94 to 1080i/59.94 or 1080i/50 to 720p/50
for example).
