Up/Down/Cross (UDX) Conversion
AirSpeed 5000 supports Up, Down or Cross (UDX) conversion of video formats. Using this
feature, you can configure a channel to allow for conversion of a clip and its ancillary data
(where available) to convert to a specific format for play-out. UDX preferences can be set in the
Playback page of the AirSpeed 5000 Management Console. The following UDX options are
available:
• Up Convert - SD video is up-converted to HD using one of five possible Up Convert options
available in the user interface.
• Down Convert - HD video is down-converted to SD using one of five possible Down
Convert options available in the user interface.
• SD Cross Convert - SD video is cross-converted (to SD) using one of six possible
SD-Cross-Convert options available in the user interface.
• HD Cross Convert - This type of conversion only has one possible outcome, which is
Anamorphically, based on the incoming video standard. If you have 1080i, it is
automatically converted to 720p. If you have 720p, it is automatically cross converted to
1080i. There is no selection in the User Interface for HD Cross Convert.
For more information on using UDX Conversion, see “The Playback Page” on page 32.
