Abstract
A decoder is provided. The decoder includes a cadence detector configured to determine whether a video stream is a pull-down stream, and remove at least one duplicate frame from the video stream, in response to determining the video stream is the pull-down stream; and a decoding module configured to decode the video stream and output decoded frames of the video stream.
Claims20
A decoder comprising:
- a cadence detector configured to determine whether a video stream is a pull-down stream, and remove at least one duplicate frame from the video stream, in response to the determining that the video stream is the pull-down stream;
- a decoding module configured to decode the video stream and output decoded frames of the video stream;
- and
- a post-processor configured to post-process the decoded frames from which the at least one duplicate frame is removed.

An application processor comprising:
- a decoder configured to decode a pull-down video stream and generate a decoded video stream from which at least one duplicate frame is removed;
- and
- a post-processor configured to post-process the decoded video stream,
- wherein the post-processor comprises:
- a frame rate conversion unit configured to convert the decoded video stream into a video stream having a predetermined frame rate;
- and
- a digital image stabilization unit configured to perform image stabilization on the decoded video stream having the pre-determined frame rate.

16-19. (canceled)
A decoder comprising:
- a cadence detector comprising a frame comparator, a frame attribute determiner, and a duplicate frame remover;
- and
- a decoding module configured to decode a video stream,
- wherein:
- the frame comparator is configured to generate a comparison result by comparing consecutive frames of the video stream with each other;
- the frame attribute determiner is configured to generate a determination result by determining whether the consecutive frames correspond to the pull-down stream, based on the comparison result;
- and
- the duplicate frame remover is configured to selectively remove the at least one duplicate frame from the consecutive frames, based on the determination result.
