This practice specifies parameters of the recorded information essential to the interchange of 2-in quadruplex video magnetic tape recording of monochrome and NTSC color signals for 525-line/60-field television systems. The parameters include video preemphasis characteristics and recorded carrier frequencies for all recording practices and video pilot specifications for practice SHBP.

Practices defined are:

Practice SHBP: This practice is suitable for color and monochrome signals. A video pilot signal is added to the recorded information to be used as a playback reference.

Practice HB: This practice is suitable for color and monochrome signals.

Practice LBM: This practice is suitable only for monochrome signals. (It is considered to be obsolescent and is included for reference purposes only.)

Practice LBC: This practice is suitable for color and monochrome signals. It is considered to be obsolescent and is included for reference purposes only.)
