MPEG2 Measurement Generator DVG is a universal generator for digital TV
signals in the form of transport streams in line with the MPEG2 standard. The
structure of these streams and the data reduction methods employed were
developed and standardized by the Moving Picture Experts Group (MPEG), the
Digital Video Broadcasting (DVB) project and the Advanced Television Systems
Committee (ATSC). A main feature of the transport stream is that it contains
several programs, each consisting of several substreams carrying video, audio
and data signals.
DVG generates in an endless loop a large variety of selectable MPEG2
transport streams with combined video, audio and data sequences as contents and
is thus a favourably priced and compact alternative to expensive MPEG2 encoders
with multiplexer and external standard generators.
Complementary to DVG, MPEG2 Measurement Decoder DVMD is offered for realtime
monitoring, analyzing and decoding of MPEG2 transport streams.
Features
Endless MPEG2 sequence loop: all the required time information (PCR,
PTS, DTS, TDT, STT) is continuously updated during play-back of the
transport stream, and the signal is available without any
interruption.
Degradation free play-out from RAM for long term operation, no
wearing out of hard disks.
Variation of the output data rate as desired and thus adapted to the
specifications of the transmission link or devices under test.
Large variety of sample transport streams compliant either to ATSC
or DVB standard and including all mandatory system and service tables.
Built-in PCR (program clock reference) jitter generator is available
for stress testing of decoder PLLs.
Ideal for use as a substitution signal source thanks to the settable
PID of the program elements.
