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 system for decompressing media content, the system comprising:

a first module configured to control a processor to receive media content divided into at least three predetermined portions;

a second module configured to control the processor to decompress each of the at least three predetermined portions using one of at least three different decompression algorithms to yield at least three decompressed predetermined portions; and

a third module configured to control the processor to make the at least three decompressed predetermined portions publicly available.

2. The system of claim 1, further comprising:

a fourth module configured to control the processor to group each of the at least three decompressed predetermined portions of the media content into at least three portions of a data frame.

3. The system of claim 2, wherein the third module is further configured to control the processor to receive the data frame over a computer network.

4. The system of claim 1, wherein the third module is further configured to controls the processor to store the at least three decompressed predetermined portions in a memory device.

5. The system of claim 4, wherein the memory device is a cache.

6. The system of claim 1, wherein at least one of the at least three decompression algorithms is a private data-based decompression algorithm.

7. The system of claim 6, wherein at least one of the at least three decompression algorithms is public data-based decompression algorithm.

8. The system of claim 6, wherein the private data-based decompression algorithm includes associated initial data, and wherein the system further comprises:

a fourth module configured to control the processor to decrypt the associated initial data of the at least one private data-based decompression algorithm to yield decrypted associated initial data publicly available; and

a fifth module configured to control the processor to make the decrypted associated initial data publicly available.

9. The system of claim 2, wherein the third module is further configured to control the processor to transmit the frame over a computer network.

10. A method of decompressing media content comprising:

receiving media content divided into at least three predetermined portions;

decompressing via a processor each of the at least three predetermined portions using one of at least three different decompression algorithms to yield at least three decompressed predetermined portions; and

making the at least three decompressed predetermined portions publicly available.

11. The method of claim 10, further comprising:

grouping each of the at least three decompressed predetermined portions of the media content into at least three portions of a data frame.

14. The method according to claim 11, wherein the step of making the at least three decompressed predetermined portions publicly available includes the step of displaying the data frame on a display.

16. The method according to claim 10, wherein at least one of the at least three decompression algorithms is a private data-based decompression algorithm.

17. The method according to claim 16, wherein at least one of the at least three decompression algorithms is a public data-based decompression algorithm.

18. The method according to claim 16, wherein the private data-based decompression algorithm includes associated initial data, the method further comprising the steps of:

decrypting the associated initial data of the at least one private data-based decompression algorithm to yield decrypted associated initial data publicly available; and

making the decrypted associated initial data publicly available.

12. A method of decompressing media content that has been divided into three portions, comprising:

decompressing via a processor each of the three portions using a different data-based decompression algorithm to yield three decompressed predetermined portions; and

making the three decompressed portions publicly available.

13. The method of claim 12, further comprising:

grouping each decompressed portion of the three decompressed portions into a portion of a frame.

15. The method according to claim 12, wherein the step of making the at least three decompressed predetermined portions publicly available includes the step of storing the at least three decompressed predetermined portions in a memory device.

19. The method according to claim 13, wherein the step of making the three decompressed predetermined portions publicly available includes the step of displaying the frame on a display.

20. The method according to claim 12, wherein the step of making the three decompressed predetermined portions publicly available includes the step of storing the three decompressed predetermined portions in a memory device.
