Rohde & Schwarz DVMD MPEG2 Measurement Analyzer

The Rohde & Schwarz DVMD is a dedicated MPEG2 Measurement Decoder engineered for real-time analysis and decoding of MPEG2 transport streams. It verifies integrity, compliance, and quality of digital video broadcasting systems across development, troubleshooting, quality management, and production environments. Operating without a PC requirement, the DVMD functions as a waveform monitor for digital television, supporting both DVB and ATSC standards while delivering detailed transport stream content analysis and quality metrics.

Technical Specifications

• Decodes video and audio streams from selected programs within MPEG2 transport streams


• Video output: CCVS, analog Y/C, and digital serial ITU-R 601 formats


• Audio output: analog stereo and digital AES/EBU signals


• Error data storage: up to 1000 entries with date/time logging


• Trigger/capture buffer: approximately 2 Mbit for bit- and byte-level analysis Analysis Capabilities:


• Real-time protocol analysis of MPEG2 transport streams


• DVB mode measurements comply with ETR290 guidelines


• Sporadic error detection with statistical reporting (error seconds)


• RS-232 interface for frozen transport stream data output

Key Features

• Standalone operation - no PC system required for basic measurements


• Real-time and in-depth decoding simultaneously


• Transport stream error capture and freeze functionality for detailed diagnostics


• Optional DVMD-B1 Stream Explorer PC software for online diagnosis and advanced visualization
