Overview
EN 61834-3:2000 (CLC adoption of IEC 61834-3:1999) defines the HD format for helical-scan digital video cassette recording systems using 6,35 mm (1/4") magnetic tape for consumer use. This Part 3 complements Parts 1 and 2 by specifying the content, format and recording method of the data blocks that form helical records for the higher-resolution systems: the 1125-line (30.00 Hz frame rate) and 1250-line (25.00 Hz frame rate) systems. The standard establishes basic principles for next‑generation consumer digital video cassette recorders (VCRs), benefitting both manufacturers and end users.
Key topics
- Data block structure: definition of the content and logical format of audio, video and system data stored in helical records on 6.35 mm tape.
- Recording method: rules for laying out data blocks along helical tracks and for handling successive frames in the HD format for 1125‑60 and 1250‑50 systems.
- Timing and resolution: specifications for the 1125‑line/30.00 Hz and 1250‑line/25.00 Hz systems that are outside Parts 1 and 2.
- System data and metadata: provisions covering non‑audio/video information required for playback, synchronization and system control.
- Interoperability principles: guidance to ensure consumer equipment from different manufacturers can read and write the defined helical records.
- Conformance scope: basic principles and format definitions intended for consumer-grade digital video cassette recording systems.
Note: EN 61834-3 sets functional and format-level requirements rather than detailed implementation algorithms; it references IEC foundations and complements Parts 1 and 2.
Applications
EN 61834-3 is directly relevant to:
- Consumer electronics manufacturers designing digital VCRs and helical-scan tape mechanisms for HD consumer formats.
- Product engineers working on tape transport, head drum timing, and data formatting for 6.35 mm cassette recorders.
- Firmware and systems designers implementing audio/video block handling, synchronization and system-data processing.
- Test laboratories and conformity assessors validating recorder compliance with HD helical-scan formats.
- Archivists and broadcasters working with legacy tape formats who need clear format specifications for migration and playback.
