Abstract
Techniques related to processing a mixed content video stream to generate progressive video for encoding and/or display are discussed. Such techniques may include determining conversion techniques for various portions of the mixed content video stream and converting the portions based on the determined techniques. The conversion of true interlaced video include content adaptive interlace reversal and the conversion of pseudo-interlaced telecine converted video may include adaptive telecine pattern reversal.
Claims20
A computer-implemented method for processing video for encoding and/or display comprising:
- receiving a mixed content video stream comprising a plurality of video formats comprising at least a true interlaced format and a pseudo-interlaced telecine converted format;
- determining a first conversion technique for a first segment of the mixed content video stream having the true interlaced format and a second conversion technique for a second segment of the mixed content video stream having the telecined format, wherein the first and second conversion techniques are different;
- and
- converting the mixed content video stream to a progressive video stream based at least in part on the first conversion technique and the second conversion technique.
At least one machine non-transitory readable medium comprising a plurality of instructions that, in response to being executed on a computing device, cause the computing device to process video for encoding and/or display by:
- receiving a mixed content video stream comprising a plurality of video formats comprising at least a true interlaced format and a pseudo-interlaced telecine converted format;
- determining a first conversion technique for a first segment of the mixed content video stream having the true interlaced format and a second conversion technique for a second segment of the mixed content video stream having the telecined format, wherein the first and second conversion techniques are different;
- and
- converting the mixed content video stream to a progressive video stream based at least in part on the first conversion technique and the second conversion technique.
A system for processing video for encoding and/or display comprising:
- a memory buffer configured to store video frames;
- and
- a central processing unit coupled to the memory buffer, the central processing unit to receive a mixed content video stream comprising a plurality of video formats comprising at least a true interlaced format and a pseudo-interlaced telecine converted format, to determine a first conversion technique for a first segment of the mixed content video stream having the true interlaced format and a second conversion technique for a second segment of the mixed content video stream having the telecined format, wherein the first and second conversion techniques are different, and to convert the mixed content video stream to a progressive video stream based at least in part on the first conversion technique and the second conversion technique.
