  • Patent number: 7468754
    Abstract: A combined de-interlacing and frame doubling system (114, 114? and 114?) 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 (116, 116? and 116?) for storing at least one frame of interlaced video having a prescribed field rate. At least one de-interlacing circuit (11401, 1140?1, 1140?) 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.

  • Patent number: 6839779
    Abstract: An apparatus for limiting a data transfer bandwidth through handshake suppression is configured to generate a first reset signal, generate a second reset signal a predetermined number of clock cycles after generating the first reset signal, generate a handshake count representing a number of receptions, between the first reset signal and the second reset signal, of a first Ready to Send (“RTS”) handshake signal and a first Ready to Receive (“RTR”) handshake signal, and disable a second RTR handshake signal and the first RTS handshake signal based on a comparison of the handshake count and a maximum value.

  • Publication number: 20040004672
    Abstract: A combined de-interlacing and frame doubling system (114, 114′ and 114″) 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 (116, 116′ and 116″) for storing at least one frame of interlaced video having a prescribed field rate. At least one de-interlacing circuit (11401, 1140′1, 1140″) 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.
