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.
