What is BS EN 61041-4 - Non-broadcast video tape recorders about?
BS EN 61041-4 discusses methods of measurement non-broadcast video tape recorders with a focus on calibration tape. BS EN 61041-4 is the fourth part of the BS EN 61041 multi-series on methods of measurement non-broadcast video tape recorders that specifies the general requirements for the calibration tape which is used for measurement of signal characteristics of the playback systems of non-broadcast video tape recorders (NTSC/PAL/SECAM).
The calibration tape specified in BS EN 61041-4 applies particularly to the measurement items prescribed in the relevant part of IEC 61041 which require complex test signals, which are unavailable from a general purpose test signal generator. The object of BS EN 61041-4 is to describe the methods of measurement for non-broadcast video tape recorders. BS EN 61041-4 describes the procedures for generating the signals and for recording the signals on the calibration tape.
Who is BS EN 61041-4 - Non-broadcast video tape recorders for?
BS EN 61041-4 on non-broadcast video tape recorders is useful for:
- Manufacturers of video tape recorders
- Video equipment manufactures
- Designers
- Engineers
Why should you use BS EN 61041-4 - Non-broadcast video tape recorders?
The video tape recorders on the market today have a very good record and playback compatibility provided that the level of the test signals and the frequencies of the carriers to be recorded are set precisely within specifications.
BS EN 61041-4 specifies the video and audio test signals to be recorded on the calibration tape that is used when measuring video and audio characteristics of non-broadcast video tape recorders, in accordance with the measurement items prescribed in IEC 61041.
BS EN 61041-4 helps improve the quality of non-broadcast video tapes.
