ABSTRACT:
A method for deinterlacing interlaced video using a graphics processor includes receiving at least one instruction for a 2D/3D engine to facilitate creation of an adaptively deinterlaced frame image from at least a first interlaced field. The method also includes performing, by the 2D/3D engine, at least a portion of adaptive deinterlacing based on at least the first interlaced field, in response to the at least one instruction to produce at least a portion of the adaptively deinterlaced frame image. Once the information is deinterlaced, the method includes retrieving, by a graphics processor display engine, the stored adaptively deinterlaced frame image generated by the 2D/3D engine, for display on one or more display devices. The method also includes issuing 2D/3D instructions to the 2D/3D engine to carry out deinterlacing of lines of video data from interlaced fields. This may be done, for example, by another processing device, such as a host CPU, or any other suitable processing device.
