Abstract:
1. An information processing apparatus having a frame buffer that stores an input video signal, wherein the information processing apparatus loads a video signal at an asynchronous timing with the video signal input from the frame buffer and performs interlaced/progressive (I/P) conversion of the loaded video signal from an interlaced signal into a progressive signal, the information processing apparatus comprising: pulldown determination means for determining whether the input video signal is of a pulldown type; matching means for identifying a plurality of resulting pulldown patterns that would result from skipping or repeating one or more frames or fields of at least a portion of the input video signal, and for comparing the plurality of resulting pulldown patterns to at least one supported pulldown pattern supported by an I/P conversion unit configured to perform the I/P conversion, the comparing comprising determining whether the plurality of resulting pulldown patterns and the at least one supported pulldown pattern include at least one matching pulldown pattern supported by the I/P conversion unit; and control means for controlling, in a case where the input video signal is of the pulldown type and the matching means identifies the matching pulldown pattern, a process of skipping or repeating one or more frames or fields of at least a portion of the loaded video signal to convert at least the portion of the loaded video signal to the at least one matching pulldown pattern supported by the I/P conversion unit.
