The HOME Test Pattern Generator (TPG) is a tool that produces video test pattern and audio test tone streams.

The video output can be configured to carry one of a number of simple test patterns. In each case, the pattern can be set to Static or Moving with options to support different Pattern Colorimetry,

On the audio side, the test tone generator provides a selection of incremental frequencies from 200Hz to 48kHz. In this instance, each audio channel carries a specific frequency: e.g. channel 1= 200Hz, channel 2= 400Hz, etc.; up to 64 channels.

Unlike other HOME Apps, up to 10x TPGs that produce SMPTE ST 2110-20/30/31 streams are included without the need for any purchased licenses. If more than 10 2110-20 TPGs, or other stream formats, are required, then the necessary Output licenses must be purchased. This is explained in more detail in HOME TPG - Licensing.

This app is part of the current release of HOME Apps, and benefits from the usual advantages of a HOME Apps environment: deployment on standard network servers; instant availability; flexible resource allocation through Lawo Flex licensing; integration with external broadcast control systems, such as Lawo's VSM.
