  • Patent number: 7269785
    Abstract: According to the invention, a technique for operating a digital versatile disk (DVD) system is disclosed. First digital information is read from a DVD player. The first digital information is decompressed to create second digital information that is stored. In order to produce third digital information different from the second digital information, the second digital information is manipulated. At some point, the third digital information is displayed.

  • Patent number: 7194189
    Abstract: A method and an apparatus for performing the method of decoding and playing in reverse MPEG encoded content. The MPEG encoded content comprises a plurality of pictures frames. The picture frames are comprised of one or more picture frame types selected from the group of picture frame types including I-frames, P-frames, and B-frames. The method and the apparatus for performing the method comprise the steps of obtaining a group of MPEG picture frames (“GOP”), determining the total number of picture frames in the GOP, and setting an index value equal to the total number of picture frames in the GOP. Next, a picture frame F that has a display order equal to the index value is decoded and displayed, and the earliest B-frame that depends upon frame F is determined. All the B-frames that depend upon frame F are decoded and displayed from highest display order to lowest display order, and the index value then is set to a value equal to one less than the display order of the earliest B-frame that depends upon frame F.
