Abstract
In one embodiment, a method comprises an act of separating a progressive scanned frame into a plurality of fields. The plurality of fields includes at least a first field being a first portion of the progressive scanned frame and a second field being a second portion of the progressive scanned frame. In addition, the method further comprises an act of compressing data associated with the first portion of the progressive scanned frame and the second portion of the progressive scanned frame with interlaced compression logic.
Claims20
A method comprising:
- separating a progressive scanned frame into a plurality of fields, the plurality of fields including a first field being a first portion of the progressive scanned frame and a second field being a second portion of the progressive scanned frame;
- and
- compressing data associated with the first portion of the progressive scanned frame and the second portion of the progressive scanned frame with interlaced compression logic.
A video source comprising:
- a first logic component to separate a progressive scanned video frame into a plurality of fields each including data associated with both even and odd scan lines;
- and
- a compression logic component to perform compression operations on each of the plurality of fields.
A video display comprising:
- an interlaced Moving Picture Experts Group (MPEG) coder/decoder (MPEG codec) to decompress an incoming video frame to recover a progressive scanned video frame including a plurality of fields, each of the plurality of fields including data associated with both even and odd scan lines of the progressive scanned video frame;
- and
- a logic component to join the plurality of fields to produce the progressive scanned video frame.
