DVRG is a universal processing platform for digital video streams. It allows the record and play of MPEG2 transport streams. This is done either degradation free using the RAM when the transport stream is of limited length or directly
using the hard disk. Minimum wear an tear can thus be achieved during continuous operation.
For error analysis, recording can be controlled by means of an external trigger signal. The stored signal includes time sections of different lengths before and after the trigger event.
In its key functions, DVRG is operated as a separate unit via keys on the front panel and the LC display. DVRG contains a PC platform with the Windows NT embedded operating system whose features are available through the connection of VGA monitor, keyboard and mouse. For example, further software packages for the analysis and generation of transport
streams can be installed and used. With the standard 100baseT connector, DVRG is easy to network for the remote control and transfer of transport stream files.
As a novelty, DVRG fitted with option DVRG-B4 and -B2allows the recording and replay of uncompressed video streams in SDI format (to ITU-R B.T. 601/ 656 or SMPTE259M) on the same platform at a data rate of 270 Mbit/s.
Thanks to its versatility and configurability, DVRG is a highly flexible working platform for all those handling digital video
signals to the MPEG2, DVB and ATSC or SDI standard.
