Abstract
A method and system for performing inverse telecine processing requires a minimum amount of memory capacity. Specifically, the inverse telecine processing technique requires only first and second dual field buffers. The first dual field buffer has a first even buffer (1E) and a first odd buffer (1O). The second dual field buffer has a second even buffer (2E) and a second odd buffer (2O). The input video sequence to be processed comprises a sequence of video fields of alternating even and odd parity. The even fields of the input sequence are written into the even buffers of the two dual field buffers on an alternating basis and the odd fields of the input sequence are written into the odd buffers of the dual field buffers on an alternating basis. This order is changed (i.e., toggled) when a repeat field is detected. The repeat field is dropped by writing over it with the next field of the same parity in the input sequence.
