Abstract
One embodiment of a de-interlacing device has a decoder that extracts decoding motion vector data for use in de-interlacing of decompressed picture data, from an MPEG-2 type compressed data stream containing interlaced decompressed picture data made up of macroblock of data. The de-interlacing device also has a video rendering device for receiving the extracted decoding motion vector data from the decoder. The decoder has a determinator for determining whether the macroblock of data contains motion based on the decoding motion vector data and at least a subset of the block of data. The decoder generates motion vector based de-interlacing information containing information indicating whether each macroblock contains motion or no motion and if desired, a level of confidence that the referenced data is suitable for a particular method of de-interlacing. The video rendering device de-interlaces the interlaced picture data on a macroblock of data basis by applying an adaptive motion filtering algorithm to the interlaced picture data for display on the progressive display device.
