Helical-scan video tape cassette system using 12,65 mm (0,5 in) magnetic tape on type VHS -- Part 4: S-VHS video cassette system - ET-mode
The S-VHS ET mode records an S-VHS signal format on a VHS cassette. In this mode, several video signal system recording parameters are switched so that the signal characteristics recorded on the VHS tape are equivalent to S-VHS recording on S-VHS tape. Cassettes recorded in the S-VHS ET mode can be played with an S-VHS based playback system and an VHS equivalent that includes the SQPB function.

Overview
EN 60774-4:2003 (CLC) specifies the S‑VHS ET‑mode for helical‑scan video tape cassette systems using 12.65 mm (0.5 in) magnetic tape in the VHS format. The standard defines how an S‑VHS signal format is recorded onto a standard VHS cassette by switching specific recording parameters so that the recorded signal characteristics on VHS tape are equivalent to S‑VHS recordings on S‑VHS tape. Cassettes recorded in S‑VHS ET‑mode are playable on S‑VHS playback systems and on VHS playback equipment that implements the SQPB function. This European adoption aligns with IEC 60774‑4:2002.
Key topics and requirements
- Scope of ET‑mode recording: Describes that S‑VHS signal formats can be recorded onto standard VHS cassettes by altering recording parameters.
- Recording parameter switching: Specifies that multiple video system recording parameters are switched to achieve signal equivalence with native S‑VHS recordings (the standard defines the mode concept; specific parameter values are covered in the normative text).
- Playback compatibility: Requires that tapes recorded in ET‑mode be playable on S‑VHS playback systems and on compatible VHS players that include the SQPB function, ensuring interoperability across equipment types.
- Format and system alignment: Part of the EN/IEC 60774 series addressing helical‑scan VHS cassette systems on 12.65 mm magnetic tape; Part 4 focuses specifically on S‑VHS ET‑mode behavior.
Applications
- Video equipment manufacturers: Implement ET‑mode recording and playback logic in VCRs and professional recording devices to support hybrid S‑VHS-on‑VHS workflows.
- Cassette and tape producers: Ensure media and labeling practices accommodate ET‑mode use and playback expectations.
- Broadcasters and archivists: Use ET‑mode to capture higher‑quality S‑VHS signals on widely available VHS cassettes for compatibility or transitional workflows.
- Repair technicians and test labs: Validate device compliance with S‑VHS ET recording/playback interoperability and SQPB‑enabled playback performance.
- System integrators and standards compliance teams: Reference EN 60774‑4:2003 when specifying product compatibility or documenting support for S‑VHS ET operation.
