<p>A computer readable medium and method are disclosed for providing streaming video by compressing the video data in a cascaded fashion (Fig. 2). Initially, a computer system compresses video data to a first intermediate data file using a first transform (204). Next, the computer system compresses the first intermediate data file to a second intermediate data file using a second transform (206). The second intermedate data file is then compressed to a streaming video data file using a third transform (210). The streaming video data is then recorded onto a computer readable medium as streaming video data (212). In one embodiment, the first intermediate data file is an MPEG-2 (204) data file and the second intermediate data file is an unconstrained MPEG-1 data file (208). The first and second transforms may be carried out in transparent mode. The video data may be stored on the computer readable medium by burning, mastering, or the like.</p> |
