IEC 61834-4:1998

IEC 61834-4:1998 defines the pack header table and contents for a helical-scan digital video cassette recording system using 6,35 mm magnetic tape for consumer use. As part of the IEC 61834 series, it helps engineers, integrators, and compliance teams understand how recorded data is structured within the cassette format, supporting technical review, documented evaluation, and interoperability checks. For organizations working on recording-system documentation or conformity assessment, IEC 61834-4:1998 provides a focused reference tied to the format’s internal pack organization.

Purpose of IEC 61834-4:1998

The purpose of this document is to define the pack header table and contents associated with the recording format described in the parent series. That makes it relevant to engineering specification control, data structure verification, and technical validation of cassette-based video recording systems. In practice, it supports a clearer understanding of how formatted information is arranged, which can be important during design review, test planning, and quality workflows where consistent interpretation of recorded data is required.

Compliance applications of IEC 61834-4:1998

IEC 61834-4:1998 is useful in compliance workflows that involve evaluation of consumer video cassette recording equipment, format documentation, or legacy system support. It may be consulted during laboratory evaluation, product evaluation, or technical assessment when confirming that recording structures align with the expected IEC 61834 format. Procurement and support teams may also use it to compare vendor documentation, verify system compatibility, and prepare evidence for conformity assessment or regulated technical documentation.

Benefits of IEC 61834-4:1998

Using IEC 61834-4:1998 can improve testing consistency and reduce interpretation risk when working with the defined recording format. By providing a clear reference for pack header table content, it supports operational consistency across engineering, verification activities, and quality assurance processes. It can also help teams manage technical documentation more effectively, strengthen conformity assessment preparation, and reduce errors during review of recording-system behavior or legacy equipment support.
