ABSTRACT:
The present invention is a combined encoder and perceptual encrypter for a file of high quality video. The combined encoder and perceptual encrypter includes an encoder and perceptual encrypter. The encoder encodes the file of high quality video as encoded data. The perceptual encryption module perceptually encrypts the encoded data in order to generate restricted video data as perceptually encrypted encoded data.
