This part of IEC 61041 specifies the general requirements for methods of measurement for high-band video tape recorders, including those equipped with Y/C video connector(s) (NTSC/PAL). This part of IEC 61041 is applicable both to machines using normal input/output connectors for the measurement of the composite video signal, and to machines using the Y/C video connector(s) (herein after referred to as S video connectors) for the measurement of the Y/C separated video signal. This part of IEC 61041 is applicable when characteristics of the video and audio signals recorded and reproduced using high-band video tape recorders are to be checked and measured. The object of this part is to describe the methods of measurement for non-broadcast video tape recorders.
