Abstract
Provided are a frame conversion apparatus and method and a frame type detecting apparatus and method. The frame conversion apparatus may include a detecting unit and an inverse telecine unit. The detecting unit may determine that each data frame is a telecine frame or a progressive frame according to the rate of discrete cosine transform (DCT) operation type performed on macro blocks of the frame or the number of the macro blocks on which each type of DCT operation is performed and output frame type information. The inverse telecine unit may convert the data frames into progressive frames and output the progressive frames in response to the frame type information.
