Abstract: A method of processing video data to detect field characteristics of the data, said data having a plurality of fields, including the steps of: comparing first and second fields, said first field being a successive field of said second field; comparing pixel values of respective sub-blocks of said first field and a third field, said second field being a successive field of said third field; determining whether said first field is an interlaced field or a progressive field with respect to a successive field of said first field based on said steps of comparing.

Abstract: A method of processing video data to detect field characteristics of the data, including processing pixel values of the data to obtain differences between the values of two successive fields of the data, processing the difference values to detect interlace patterns in the successive fields, determining if the successive fields belong to a progressive frame based on detection of the interlace patterns, and generating a progressive frame output indicating that a progressive frame has been detected. The pixel values of the first field of the successive fields and a subsequent field to the successive fields are processed to obtain further difference values to determine if the subsequent field is a redundant field, when the progressive frame output is generated.
