  • Patent number: 5221966
    Abstract: A system for converting an input television signal that contains field sequences corresponding to frames in cine film is provided. The input signal is converted into an intermediate television signal wherein there is a direct correlation between the field groups thereof and the original film frames. The intermediate signal is modified to produce and output television signal whose field rate is that of a desired television signal. For example, the input signal can be an NTSC signal produced in part from a 3:2 pull down technique, the intermediate signal may be characterized by 625 lines and 48 fields per second or characterized by 525 lines and 625 fields per second, and the output signal can be a PAL signal characterized by 625 lines and 50 fields per second. In each case, a 3:2 sequence of input signal fields (correlated with cine frames) results in pairs of fields in the output signal correlated with the cine frames.
