Abstract
A signal processing apparatus for use in a video cassette recorder comprising a pilot burst gate pulse generating system means responsive to horizontal synchronizing signals successively generated in correspondance with horizontal scanning periods to process the horizontal synchronizing signals so as to produce pilot burst gate pulses. The pilot burst gate pulse generating system is responsive to a first horizontal synchronizing signal to generate the pilot burst gate pulse at a timing delayed by a predetemined time period from a leading edge of a second horizontal synchronizing signal following the first horizontal synchronizing signal. This arrangement allows stable generation of the pilot burst gate pulse at a timing slightly delayed from the active edge of the corresponding horizontal synchronizing signal.
