Rohde & Schwarz adds transport stream decoder to DVM family
February 5, 2007
Rohde & Schwarz has unveiled an optional hardware decoder for its R&S DVM family that decodes video and audio signals contained in the transport stream. This allows users to quickly identify the programs and to immediately view and assess picture quality.
The decoder is suitable for both the SD and HD formats. In addition to MPEG-2, the instrument supports the H.264 coding standard. Signals can additionally be tested by means of the buffer analysis function to determine whether they are compliant with the MPEG standard.
The new option is available for all instrument types of the company's R&S DVM MPEG-2 Measurement Platform. Various picture displays can be connected via numerous interfaces, including the HDMI interface.
The existing R&S DVM400 Digital Video Measurement System already includes a screen for displaying the graphical user interface. The decoded picture can also be directly shown on the display. With the new decoder, all models of the DVM family additionally feature an on-screen display function that gives a quick overview of the technical characteristics of the signal.
The video and audio signals of a program are decoded simultaneously. The decoder supports MPEG-2 and H.264 for video signals and all common formats from MPEG-1 Layer II to Dolby Digital for audio signals.
