Abstract:
A method for displaying resized pictures of a motion video on an interlaced target display system, comprising:reading contents of an input video source; decoding the contents of the input video source to obtain original input picture data and title format information that indicates scan format of the original input picture data including the original scanning rate of the input picture data, wherein the original input picture data does not comply with a television system specification of the interlaced target display system; identifying a television system specification of the interlaced target display system including field scanning characteristics of the interlaced target display system, wherein the television system specification is generated by a target system selector; according to the scan format of the original input picture data and the television system specification of the interlaced target display system, performing a resizing operation to resize the original input picture data and obtain resized frames having a frame size sufficient for division into even and odd fields with field size characteristics that comply with the television system specification of the interlaced target display system; and storing the resized frames in a resize memory; and according to the scan format of the original input picture data including the original scanning rate and the television system specification of the interlaced target display system including the field scanning characteristics, adjusting a frame rate by controlling the resize memory to output the resized frames in a corresponding predetermined form of alternating the even and odd fields with a timing sequence that complies with the field scanning characteristics of the television system specification of the interlaced target display system.
