Abstract
Systems and methods of coding progressive content with isolated fields for conversion to interlaced display are provided. Some systems and methods may find use in, for example, digital video compression systems and methods. Film material may be encoded as video material with an intended field polarity and an explicit 3:2 pull-down operation for interlaced display (e.g., a 30-frames-per-second display).
Claims18
A video encoder circuit comprising:
- circuitry operable to encode film material as a video with a field polarity and a 3:2 pull-down operation for an interlaced display format;
- and
- wherein the circuitry is operable to insert an encoded isolated field with the field polarity,
- wherein the circuitry is operable to generate a decoding time stamp (DTS) or a presentation time stamp (PTS) for a particular picture without knowledge of a film mode state of the particular picture.

A method for encoding video information, the method comprising:
- encoding a source material as a video material with a field polarity and a 3:2 pull-down operation for an interlaced display format;
- and
- wherein the encoding comprises inserting an encoded isolated field with the field polarity,
- wherein the encoding comprises generating a decoding time stamp (DTS) or a presentation time stamp (PTS) for a particular picture without knowledge of a film mode state of the particular picture.
1 more element
A video encoding system comprising:
- receiving circuitry operable to receive film material;
- encoding circuitry operable to encode received film material as a video with a field polarity and a 3:2 pull-down operation for an interlaced display format, wherein the encoding circuitry is operable to insert an encoded isolated field with the field polarity, wherein the encoding circuitry is operable to generate a decoding time stamp (DTS) or a presentation time stamp (PTS) for a particular picture without knowledge of a film mode state of the particular picture;
- and
- transmitting circuitry operable to transmit the encoded film material over a network.
