Portable DVD player
First Claim
1. A portable DVD player comprising:
- a generally thin prismatic enclosure having a first major surface, a second major surface separated from said first major surface, and side surfaces connecting said first major surface to said second major surface, wherein at least a portion of said first major surface includes a video display, and wherein said enclosure includes a DVD entry port such that a DVD can be inserted into said enclosure; and
a digital processing system including a decoder, a deinterlacer, and a display controller where said decoder receives signals from a DVD inserted into said enclosure to provide a decoded, interlaced video signal, said deinterlacer converts said interlaced video signal to a deinterlaced video signal, and said display controller uses said deinterlaced video signal to provide progressively scanned video on said video display.

Abstract
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.

15. A DVD signal processing system comprising:
-
a decoder decoding MPEG encoded signals derived from a DVD to produce a decoded, interlaced video signal;
a deinterlacer converting said decoded video signal to a deinterlaced video signal; and
a display controller using said deinterlaced video signal to provide progressively scanned video for a video display. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A method for providing a video display comprising:
-
receiving an MPEG encoded signal from a DVD;
decoding said MPEG encoded signal to develop an interlaced video signal; and
deinterlacing said interlaced video signal with a line doubling process to develop a progressively scanned video signal. - View Dependent Claims (23, 24)
