摘要： PROBLEM TO BE SOLVED: To provide a method of converting video data to film data.SOLUTION: A method of converting video data to film data includes deinterlacing video data from a first field and a third field to produce first field video data, providing second field video data, and merging the first field video data and the second field video data to produce first frame video data. The method further includes copying video data from a fourth field and a fifth field to produce second frame video data. An apparatus for converting video data to film data includes a first deinterlacer for deinterlacing video data from a first field and a third field to produce first field video data, and a copy module for providing second field video data and merging the first field video data and the second field video data to produce the first frame video data.

摘要： PROBLEM TO BE SOLVED: To provide improvement in a multimedia data processing apparatus and method.SOLUTION: The invention generally relates to multimedia data processing, and more particularly, to processing operations performed prior to or in conjunction with data compression processing. A method of processing multimedia data includes: receiving interlaced video frames; obtaining metadata for the interlaced video frames; converting the interlaced video frames to progressive video using at least a portion of the metadata; and providing the progressive video and at least a portion of the metadata to an encoder for use in encoding the progressive video. The method can also include generating spatial information and bi-directional motion information for the interlaced video frames, and generating progressive video based on the interlaced video frames using the spatial and bi-directional motion information.
