Abstract:
A display control device comprising:a decoder configured to decode video contents data to produce television field data wherein the video contents data includes at least one of interlace field data and progressive frame data, the video contents data further including a progressive flag indicating whether the video contents data is interlace field data or progressive frame data, the decoder further configured to output the television field data and the progressive flag to a graphic controller, wherein: the graphic controller is connected to the decoder and configured to convert the television field data into non-interlace frame data based on the progressive flag such that one non-interlace frame data is synthesized based on two television field data if the progressive flag indicates that the video contents data is progressive frame data and one non-interlace frame data is synthesized by interpolating one television field data if the progressive flag indicates that the video contents data is interlace field data, the video contents data further includes a repeat flag indicating whether repeat field data is to be output from the decoder, the decoder is further configured to output the repeat flag to the graphic controller, the graphic controller is further configured to skip the television field data for conversion if the repeat flag indicates that the repeat field data is to be output, the decoder is further configured to output a vertical sync signal to the graphic controller and, if the repeat flag indicates that the repeat field data is to be output, to mask the vertical sync signal, the graphic controller is further configured to capture the television field data based on the vertical sync signal, the decoder is further configured to output a horizontal sync signal to the graphic controller and, if the repeat flag indicates that the repeat field data is to be output, to mask the horizontal sync signal, and the graphic controller is further configured to capture the television field data based on the horizontal sync signal.
