Video Conversion

Each Receiver service can convert an input video resolution to a different output resolution (i.e. up-conversion or down-conversion). The processed video can be passed through to output standards such as SDI, SMPTE ST 2022-6, or SMPTE ST 2110.

Supported Conversions

The following output resolution conversions are supported. Frame-rate is preserved; conversions between interlaced and progressive formats are supported where applicable.

Input resolution SD Output 720p Output 1080i Output 1080p Output 2160p Output
UHD ✔ ✔ ✔ ✔
1080p ✔ ✔ ✔
1080i ✔ ✔ ✔
720p ✔ ✔
SD ✔

Configuring Video Scaling

Video conversion is controlled using the Video Scaling option. It is also available when Multiple Outputs have been added.

Info: If the decoded input format is not supported by the target output (for example, UHD routed to a 3G-SDI-capable output port), the video must be down-converted to a supported format such as 1080p.

Enabling Video Scaling

To enable video scaling for a specific Receiver service, follow these steps:

  1. On the Home page, select the RECEIVER item from the required feed, then click Edit to edit.

  2. In the Parameters window, select the Output tab.

  3. From the Video scaling drop-down menu, select the required output resolution. Select No scaling to disable conversion.

  4. After completing the configuration, click Save and Continue to apply the changes.

Info: If the decoded input format and the selected Video scaling is not supported, an alarm will be raised.
