1. A processing device comprising:
a pull-down cadence detector configured to receive an input video stream generated by pulling down raw data from an external device, detect a pull-down cadence format indicating a rate at which the raw data is pulled down based on the input video stream, and output detection result information including a type of the pull-down cadence format; and
a pull-down cadence controller configured to output an output video stream having a second frame rate that is an integer multiple of a first frame rate of the raw data, based on the input video stream and the detection result information, by bypassing the input video stream or changing a third frame rate of the input video stream to the second frame rate according to the type of the pull-down cadence format,
wherein the pull-down cadence controller is configured to bypass the input video stream when the type of the pull-down cadence format is a linear pull-down cadence format, and
wherein the linear pull-down cadence format indicates a pull-down ratio at which the third frame rate is an integer multiple of the first frame rate.
