Abstract

An apparatus for compressing media content is disclosed. The apparatus divides the media content into at least three predetermined portions, compresses each of the at least three portions using one of at least three different compression algorithms and makes the at least three compressed predetermined portions publicly available. Making the portions publicly available includes, for example, transmitting the portions over a computer network such as the Internet.

Claims

1. A method comprising:

analyzing, via a processor, a media content to determine a first portion and a second portion;

obtaining a first initial data associated with the first portion, wherein the first initial data comprises first adaptive data associated with an adaptive code-book, first fixed data associated with a fixed code-book, and first quantization data associated with gain quantization of the first portion;

obtaining a second initial data associated with the first portion, wherein the second initial data comprises second adaptive data associated with the adaptive code-book, second fixed data associated with the fixed code-book, and second quantized data associated with gain quantization of the second portion;

encoding the first portion using the first initial data to yield a first compressed portion; and

encoding the second portion using the second initial data to yield a second compressed portion.

2. The method of claim 1, wherein the first compressed portion and the second compressed portion are encoded using different algorithms.

3. The method of claim 1, wherein the fixed code-book comprises a public Huffman code-book.

4. The method of claim 1, wherein the adaptive code-book comprises a private Huffman code-book.

5. The method of claim 1, further comprising communicating at least one of the first compressed portion and the second compressed portion over a computer network.

6. The method of claim 1, wherein at least one of the first portion and the second portion is a null portion of the media content.

7. The method of claim 1, wherein the first portion and the second portion are separated by a predetermined header code within the media content.

8. A system comprising:

a processor; and

a storage device storing instructions for controlling the processor to perform steps comprising;

analyzing a media content to determine a first portion and a second portion;

obtaining a first initial data associated with the first portion, wherein the first initial data comprises first adaptive data associated with an adaptive code-book, first fixed data associated with a fixed code-book, and first quantization data associated with gain quantization of the first portion;

obtaining a second initial data associated with the first portion, wherein the second initial data comprises second adaptive data associated with the adaptive code-book, second fixed data associated with the fixed code-book, and second quantized data associated with gain quantization of the second portion;

encoding the first portion using the first initial data to yield a first compressed portion; and

encoding the second portion using the second initial data to yield a second compressed portion.

9. The system of claim 8, wherein the first compressed portion and the second compressed portion are encoded using different algorithms.

10. The system of claim 8, wherein the fixed code-book comprises a public Huffman code-book.

11. The system of claim 8, wherein the adaptive code-book comprises a private Huffman code-book.

12. The system of claim 8, wherein the storage device stores further instructions for controlling the processor to perform a further step comprising:

further comprising communicating at least one of the first compressed portion and the second compressed portion over a computer network.

13. The system of claim 8, wherein at least one of the first portion and the second portion is a null portion of the media content.

14. The system of claim 8, wherein the first portion and the second portion are separated by a predetermined header code within the media content.

15. A non-transitory computer-readable storage medium storing instructions which, when executed by a computing device, cause the computing device to perform steps comprising:

analyzing a media content to determine a first portion and a second portion;

obtaining a first initial data associated with the first portion, wherein the first initial data comprises first adaptive data associated with an adaptive code-book, first fixed data associated with a fixed code-book, and first quantization data associated with gain quantization of the first portion;

obtaining a second initial data associated with the first portion, wherein the second initial data comprises second adaptive data associated with the adaptive code-book, second fixed data associated with the fixed code-book, and second quantized data associated with gain quantization of the second portion;

encoding the first portion using the first initial data to yield a first compressed portion; and

encoding the second portion using the second initial data to yield a second compressed portion.

16. The non-transitory computer-readable storage medium of claim 15, wherein the first compressed portion and the second compressed portion are encoded using different algorithms.

17. The non-transitory computer-readable storage medium of claim 15, wherein the fixed code-book comprises a public Huffman code-book.

18. The non-transitory computer-readable storage medium of claim 15, wherein the adaptive code-book comprises a private Huffman code-book.

19. The non-transitory computer-readable storage medium of claim 15, wherein at least one of the first portion and the second portion is a null portion of the media content.

20. The non-transitory computer-readable storage medium of claim 15, wherein the first portion and the second portion are separated by a predetermined header code within the media content.
