MPM1 Video Transcoding

Inputs and Outputs

The MPM1 Transcoder has no external inputs or outputs. All data is passed into and out of

the module via the internal connectors.

Overview

The MPM1 can transcode up to twelve SD-to-SD streams or up to four transcodes with HD

streams on input and/or output, or a combination of both. Each high-definition stream

reduces the maximum number of standard-definition streams by three

Video Compression Functionality

The supported formats and bit rates are summarised in the Coded Elementary Stream page

Any supported video format can be transcoded to any other supported video format, with

the following exceptions:

720p outputs can only be transcoded from 720p inputs

1080PsF outputs can only be transcoded from 1080PsF inputs

720p inputs cannot be transcoded into 1080i outputs

Any supported PIP format can be generated from any supported input video format

Loss of Video Input

On loss of video input, the MPM1 can be configured to select one of the default test patterns

or a freeze frame as the output.
