Abstract

Applies to magnetic video recording and/or reproduction using 12.65 mm (0.5in) tape cassettes on helical-scan video cassette recorders suitable for broadcast applications. Defines the electrical and mechanical characteristics of equipment which will provide for interchangeability of recorded cassettes. The requirements given are related to 525 line-60 field and/or 625 line-50 field systems.
