This document describes the way to upscale a Standard Definition (SD) service to High Definition (HD) using the Cisco DCM equipped with a Multi Format Processing (MFP) card and transcoding license .
In order to upscale from SD MPEG-2 to HD MPEG4 we need a Cisco DCM with MFP card configured to have at least one HD engine (2 HD Video) and transcoding license:
The following steps demonstrate how a Cisco DCM can be configured to upscale a Video service:
Step 1: Pass the service to the MFP card for processing
Step 2: Enable the video for transcoding
Step 3: Configure the video resolution
Step 4: Pass the service to the output
An alarm will raise if the transcoded service Frame Rate does not match the input Frame Rate. In this case the user will not be able to start the streaming,
Let's take the following example:
The default rate of an incoming SD video is 25 fps.
You can view the properties of the service on the MFP card once transcoding is started:
At the moment the encoding is defined as HD video it will have the auto Frame Rate of 29.97 fps:
If the rate is not changed to match the SD rate of 25 fps then after the service is routed to the output the below alarm will appear:
The invalid Frame Rate Conversion alarm will be generated and the service will be blocked.
Once the rate is set back to 25 (as the MPEG2 default SD channel has) the alarm will clear and the up-scaled service will be available at output.
