    摘要: A portable DVD player includes a generally thin prismatic enclosure having a first major surface, a second major surface separated from the first major surface, and side surfaces connecting the first major surface to the second major surface. At least a portion of the first major surface includes a video display. The enclosure further includes a DVD entry port such that a DVD can be inserted into the enclosure. A digital processing system within the enclosure includes a decoder, a deinterlacer, and a display controller. The decoder receives signals from a DVD inserted into the enclosure to provide a decoded, interlaced video signal, the deinterlacer converts the interlaced video signal to a deinterlaced video signal, and the display controller uses the deinterlaced video signal to provide progressively scanned video on the video display. Preferably, the portable DVD player is both mechanically and electronically isolated for physical shocks to the player.

    摘要: Apparatuses and methods are described for performing time base correction and frame rate conversion with respect to signals. An apparatus includes circuitry to synthesize an output video clock. The apparatus has circuitry that receives an input video synchronization signal. The apparatus has circuitry to change a frequency of the output video clock based on an intended number of video clock cycles per input vertical period and a period of the input video synchronization signal.

    摘要: A digital image processor is provided. The digital image processor includes a deinterlacing processor that is implemented upon a digital processing unit. The deinterlacing processor is coupled to an input operable to receive an interlaced video stream, a digital memory for storing portions of the interlaced video signal, and an output operable to transmit a deinterlaced video stream. The deinterlacing processor is operable to detect the source type of the received interlaced video stream to generate the deinterlaced video stream having reduced or no motion artifacts.

    摘要: A digital image processor includes an input buffer for storing raster-scanned data. A slice-buffer memory is coupled to the input buffer to store a portion of a vertical slice of said raster-scanned data. The vertical slice is processed by a vertical slice processor having an input coupled to the slice-buffer memory. The vertical slice processor reassembles the vertical slices into processed raster-scanned data in an output buffer that is coupled to the output of the vertical slice processor. The digital image processor preferably utilizes multiple sequential processing stages and processes the raster-scanned data along the horizontal axis of the vertical slices.
