MPEG2 Measurement Decoder DVMD monitors and analyses the MPEG2 transport stream. It indicates the contents and provides comprehensive information on the quality of the transport stream.
The combination of decoder and analyser in one unit with conventional operating concept (no PC system) makes DVMD the waveform monitor of digital television. It is suitable for use wherever MPEG2 signals have to be checked.
Realtime measurements and simultaneous in-depth analysis yield extremely fast results. This makes DVMD an indispensable tool in development, in troubleshooting as well as in quality management and production.
Another important application is in the final inspection of MPEG2 signals before they leave the studio. While DVMD checks the video and audio signals at the output, error information is inserted directly into the decoded program (on-screen display).
Remote control capability allows integration into automatic monitoring networks. DVMD is thus ideal for network operators.
Complementary to Decoder DVMD, MPEG2 Measurement Generator DVG is offered for providing continuous MPEG2 transport streams made up of video, audio and data sequences in an endless loop.
Optional alarm lines and parallel printer interface (DVMD-B5)
In addition to a second parallel printer interface, 12 alarm lines for signaling errors detected in the transport stream are available. Each alarm line can be allocated to one or several (ORed) types of errors. The contacts close to ground and in case of an error they can be chosen to close or open.
