Embodiments of the present invention are directed to a system and method for recursive noise reduction. An exemplary method comprises receiving a first film frame having a first frame rate and a second film frame having the first frame rate and converting the first film frame into a first plurality of video frames having a second frame rate. The exemplary method further comprises converting the second film frame into a second plurality of video frames having the second frame rate, wherein the first plurality of video frames is positioned adjacent the second plurality of video frames at a border between the first plurality of video frames and the second plurality of video frames and updating a noise reduction correction signal only on the border between the first plurality of video frames and the second plurality of video frames when operating in a first mode.

Recursive noise reduction system and method for film-based video

A combined de-interlacing and frame doubling system (' and&#x2033;) advantageously serves to de-interlace successive lines of Present Field Video data at twice the field rate to yield an output bit stream suitable for display on display device that utilizes progressive scanning. The de-interlacing and frame doubling system in accordance with present principles includes a frame memory mechanism (&#x2032; and&#x2033;) for storing at least one frame of interlaced video having a prescribed field rate. At least one de-interlacing circuit (&#x2033;) pulls at least two fields of video data from the memory mechanism at a rate of at least twice the field rate for performing a full de-interlacing function in half of a field period to generate the a progressive, frame doubled signal for receipt at the display device.

High-definition de-interlacing and frame doubling circuit and method

A method of converting interlaced video to progressive video can include a series of steps. The method can include receiving a video signal representative of at least one picture and determining whether the picture is progressive. If the picture is progressive, a vertical synchronization signal is modified to create an association with a first field of the picture. Accordingly, a progressive video signal can be converted to an interlaced video signal associated with the vertical synchronization signal and the interlaced video signal can then be converted to a progressive video signal in correspondence with modifications made to the vertical synchronization signal.

A combined de-interlacing and frame doubling system (and) advantageously serves to de-interlace successive lines of Present Field Video data at twice the field rate to yield an output bit stream suitable for display on display device that utilizes progressive scanning. The de-interlacing and frame doubling system in accordance with present principles includes a frame memory mechanism (and) for storing at least one frame of interlaced video having a prescribed field rate. At least one de-interlacing circuit () pulls at least two fields of video data from the memory mechanism at a rate of at least twice the field rate for performing a full de-interlacing function in half of a field period to generate the a progressive, frame doubled signal for receipt at the display device.

A memory management process for buffering progressive, interlaced, CCIR 601/656 compliant, and MPEG compliant video signals in a video memory that is partitioned into first and second buffers. The process includes identifying the format of a received video signal, buffering the received video signal in the video memory in accordance with a standard buffering mode if the video signal is in an interlaced, CCIR 601/656 compliant, or MPEG compliant format, and buffering the received video signal in the video memory in accordance with an override buffering mode if the video signal is in a progressive format such as a 240p signal generated by a game console, VCR, cable text generator, and the like.

Processing of progressive video signals in digital TV receivers

A horizontal synchronizing system, comprising: a source of a horizontal synchronizing signal; a source of first and second higher frequency horizontal drive signals; a phase detector for generating a first control voltage responsive to the horizontal synchronizing signal and the first horizontal drive signal; a source of a second control signal; and, a switch for selectively supplying the first control signal to the source of the drive signals for a phase-locked mode of operation at the first higher frequency and supplying the second control signal to the source of the drive signals for a phase-unlocked mode of operation at the second higher frequency.
