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.

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. The process then repeats by obtaining, decoding and displaying the next frame F having a display order equal to the index value, and decoding and displaying the B-frames that depend upon the frame F.

Abstract translation: 一种用于执行在反向MPEG编码内容中解码和播放的方法的方法和装置。 MPEG编码的内容包括多个图片帧。 图像帧由从包括I帧，P帧和B帧的图像帧类型组中选择的一个或多个图像帧类型组成。 用于执行该方法的方法和装置包括以下步骤：获得一组MPEG图像帧（“GOP”），确定GOP中的图像帧的总数，并且设置等于图像帧总数的索引值 在GOP中。 接下来，解码并显示具有与索引值相等的显示顺序的图片帧F，并且确定依赖于帧F的最早的B帧。 依赖于帧F的所有B帧被解码并从最高显示顺序显示到最低显示顺序，然后将该索引值设置为等于小于依赖于最早的B帧的显示顺序的一个值 然后，该过程通过获得，解码和显示具有等于该索引值的显示顺序的下一帧F，并且解码和显示依赖于帧F的B帧来重复该过程。
