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
Decoding and Output Formats:
• 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
• Stream Explorer activation of real-time analyses with graphic representation output to PC monitor
– Typical Applications
• DVB and ATSC standard compliance verification
• Digital video transport stream quality assessment
• Production monitoring and real-time signal integrity checks
• Development and system troubleshooting
– Compatibility & Integration
The DVMD pairs with the Rohde & Schwarz DVG MPEG-2 Measurement Generator, which supplies predefined MPEG2 transport streams selectable via keypad control. Optional enhancement interfaces expand connectivity options beyond the standard RS-232 configuration.
