Abstract
A video production system, which has realized an effective utilization of many existing broadcasting equipments (a time-code generator, an editing controller, etc.) that require a framing with a frequency of 30 Hz and also equipments that function according to a standard of the present time-code defined by a unit of 30 Hz, for a progressive scanning TV format which does not accept a framing by frequency of 30 Hz. An interlaced scanning TV synchronizing signal, which is synchronized of field with a progressive scanning TV signal, is coupled with various kinds of broadcasting equipments (VTRs and , a time-code generator and an editing controller ) from a progressive scanning TV synchronizing signal source . In this way, an entire video production system of the progressive scanning TV format is synchronized with the interlaced scanning TV synchronizing signal, and is capable of being synchronized with 30 Hz. Furthermore, by supplying the interlaced scanning TV synchronizing signal to the entire system, the video production system of the progressive scanning TV format is able to use equipments (an editing controller, a time-code signal generator, etc.) of the conventional interlaced scanning TV format.
