Claims
- 1. A method for manufacturing a compact disk, the method comprising the steps of:
- compressing media content using a lossy compression algorithm;
- decompressing the compressed media content using a corresponding decompression algorithm, so that when the media content is again compressed and decompressed, a quality of the media content is substantially degraded so as to deter a piracy of the media content; and
- recording the compressed-decompressed media content onto the compact disk.
- 2. The method according to claim 1, wherein the media content comprises a master media content.
- 3. The method according to claim 2, wherein the compression and decompression algorithms comprise a Perceptual Audio Coder compression-decompression algorithm.
- 4. The method according to claim 2, wherein the compression and decompression algorithms comprise an Advanced Audio Coder compression-decompression algorithm.
