5.2 Weighting curve for CCIR System 625/50
6. Time base stability at playback speeds different
     from the nominal value
6.1 Signal transitions
6.2 Horizontal synchronizing signal
6.3 Vertical synchronizing signal
Figures
1. Signal transition (one field) - One head is used per
     scan
2. Signal transitions (one field) = More than one head
     is used per scan
3. Test arrangement for checking the distortion of the
     synchronizing signal due to signal transitions
     during playback in "trick"-mode

Specifies time base errors and their characteristics and maximum figures for the monochrome and colour composite video signal reproduced from two-head helical-scan domestic video recorders.
