Abstract
A digital audio video recorder captures a stream of audio video (AV) data targeted for output onto a computer display. The content is intercepted from a DVD playback, an internet data stream, an audio disc or another audio, video or audio-video source and routed to a select encoder for compression. Various encoders are available for recording at varying fidelity and speed. The intercepted also is encrypted with a key. The key is specific to the medium to which the captured AV stream is stored. The encryption step prevents the AV content from being distributed, but allows the AV stream to be played back later from the same medium onto which it was captured. The AV stream is compressed and encrypted on a frame by frame or a batch-frame basis.
