R&S^®DVQ-B1 Quality Explorer

Quality Explorer DVQ-B1 from Rohde&Schwarz is a software package that performs comprehensive analysis on MPEG2-coded transport streams concering picture quality. It can be used either on an external PC connected to DVQ or fully independently of DVQ for elementary stream analysis from data media (eg hard disk, CD-ROM).

DVQ-B1 comprises two independent tools:

The Quality Monitor reads the quality parameters provided by the Digital Video Quality Analyzer DVQ in real time via the remote-control interface. It displays the quality levels graphically as a histogram. Archiving on data storage media is also possible.

The Elementary Stream Analyzer analyzes the content of MPEG2-coded video elementary streams. For this purpose DVQ has a 32 Mbit internal buffer memory for the elementary stream to be analyzed. The elementary stream buffered in DVQ can also be stored as a PC file.

Alternatively, elementary streams available in the form of PC files can be analyzed. Therefore, Quality Explorer™ can be used on other instrument platforms without the DVQ. Full remote control of DVQ is provided by a library routine (DLL) supplied with the software and the Quality Monitor's user interface.

The software runs under Windows 95/98 or Windows NT on any PC or laptop connected to the DVQ via a serial (RS232) or Ethernet network (10BaseT) interface. The easy-to-operate software, as well as the clear presentation of the analysis results in windows of variable size, ensure speed and success right from the start.
