Product Overview

The MTG100 and MTG300 MPEG Generators store and playback MPEG-2
transport streams that are compliant with ATSC, DVB, and ARIB standards. The
MPEG generators can automatically update the time stamp values of the
transport stream in real time to support long term playout. Table 1-1 lists the
main features of the MPEG generators.

You can output transport streams stored in the MPEG generators to perform the
following tasks:

H Evaluate IRD/STB designs and manufacturing processes

H Evaluate performance of MPEG-2 equipment

H Perform conformance testing of MPEG-2 systems

H Provide substitute signal generation for digital television transmitters

The MTG300 MPEG Generator facilitates complete stress testing by providing
comprehensive capabilities to customize stored transport streams. In addition, the
MTG300 MPEG Generator allows you to effectively monitor receiver operation
by inserting PSI/SI/PSIP tables into the transport stream.
