Abstract

A distributing system includes an encoder, a perceptual encryption module and a server. The encoder encodes the file of high quality video as encoded data in MP3 format. The encoded file has a plurality of frames. Each frame has a header with a sync and side information and main information. The perceptual encryption module perceptually encrypts the encoded data in MP3 format to generate restricted video data as perceptually encrypted encoded data. The server with a memory bank stores and distributes the perceptually encrypted encoded data. A receiving system receiving system includes a receiver with a memory bank, a perceptual decryption module and a decoder. The receiver receives and stores the perceptually encrypted encoded data. The perceptual decryption module perceptually decrypts the perceptually encrypted encoded data to generate encoded data in MP3 format. The decoder decodes the file of encoded data in MP3 format to generate high quality video.

Claims

1. A video distribution system comprising:

a. a movie capture facility for capturing a movie content having a corresponding title and for producing therefrom digital data representing the movie content in the form of a movie data file;

b. a movie storage facility coupled to receive and store the movie data file;

c. a central host server coupled to the movie storage facility for cataloging a movie data file with the corresponding title and for retrieving the movie data file from the movie storage facility upon receipt of a transfer request;

d. a communications network coupled to the central host server for receiving the movie data file and for transmitting the movie data file over the communications network;

e. a remote server coupled to the communications network for receiving the movie data file;

f. a selection device coupled to the remote server for selecting the movie content for manufacture;

g. a production device coupled to the remote server and the selection device for reproducing the movie content from the movie data file; and

h. a decoding apparatus connected between the remote server and the production device and operable for receiving the movie data file, for parallel decompressing the movie data file and for producing therefrom a plurality of parallel bit streams of the digital data representing the movie content and the production device further operable for manufacturing the movie content from the parallel bit streams received from the decoding apparatus.

3. A receiving system for a file of high quality video for use with said distributing system of claim 1 wherein said receiving system comprises:

a. a receiver with a memory bank which receives and stores said perceptually encrypted encoded data;

b. a perceptual decryption module coupled to said receiver wherein said perceptual decryption module perceptually decrypts said perceptually encrypted encoded data to generate encoded data in MP3 format; and

c. an decoder coupled to said perceptual encryption module wherein said decoder decodes the file of encoded data in MP3 format to generate high quality video.

2. A distributing system for a file of high quality video, said distributing system comprising:

a. an encoder which encodes the file of high quality video as encoded data in MP3 format wherein the encoded file has a plurality of frames each of which has a header with a sync and side information and main information;

b. a perceptual encryption module which perceptually encrypts said encoded data in MP3 format to generate restricted video data as perceptually encrypted encoded data; and

c. a server with a memory bank which stores and distributes said perceptually encrypted encoded data.
