Overview
EN 61834-2:1998 (adopted by CLC / identical to IEC 61834-2:1998) defines the SD format for a consumer helical‑scan digital video cassette recording system using 6,35 mm magnetic tape. Part 2 specifies the content, format and recording method of the data blocks that form the helical records on tape for the 525‑line (29.97 Hz) and 625‑line (25.00 Hz) systems. The standard covers recording of one digital video channel, two independent digital audio channels and associated system data for consumer use.
Key topics and technical requirements
- Data block content and format: Defines how audio, video and system information are packaged into data blocks that form each helical record on the tape.
- Recording method: Specifies the helical‑scan layout and the method by which the blocks are written to and read from 6.35 mm magnetic tape.
- System coverage: Targets the 525‑60 (NTSC‑rate) and 625‑50 (PAL‑rate) SD systems, addressing frame rates of 29.97 Hz and 25.00 Hz respectively.
- Channels and multiplexing: Standardizes one digital video channel plus two independent audio channels and how system metadata is incorporated into the stream.
- Consumer orientation: Requirements tailored for consumer‑level digital video cassette recorders and media (interoperability, recording/playback behavior).
Note: This summary reflects the scope provided in EN 61834-2:1998 and does not add proprietary or implementation‑specific parameters not contained in the standard text.
Applications
- Manufacturers of consumer digital video cassette recorders (DVCRs) and cassette mechanisms implementing the SD format on 6.35 mm tape.
- Tape/media producers ensuring recorded media complies with EN 61834-2 for compatibility.
- Service, repair and test laboratories validating playback and recording conformity for 525‑60 and 625‑50 consumer devices.
- Archivists and digital preservation teams working with legacy helical‑scan digital tapes in the SD 525/625 formats seeking interoperable reading and migration strategies.
- Standards developers and technical authors referencing the SD format for product specifications and interoperability documentation.
Related standards
- IEC/EN series for helical‑scan digital video cassette systems (EN 61834 series). EN 61834-2 corresponds to IEC 61834-2:1998 and focuses on the SD format for 525‑60 and 625‑50 systems. Other parts of the series address alternate formats, higher‑resolution systems and implementation guidance.
