Abstract

A system and method are provided for compressing data. Initially, data is received in a single device. Such data is encoded utilizing the single device to generate first compressed data in a first format. Moreover, the first compressed data is transcoded utilizing the single device to generate second compressed data in a second format.

Claims

1. A method for compressing data, comprising:

receiving data in a single device;

encoding the data utilizing the single device to generate first compressed data in a first format; and

transcoding the first compressed data utilizing the single device to generate second compressed data in a second format.

2. The method as recited in claim 1, wherein the encoding occurs in real-time.

3. The method as recited in claim 1, wherein the transcoding occurs off-line.

4. The method as recited in claim 1, wherein the first compressed data is transcoded to generate the second compressed data in the second format such that the second compressed data is adapted to match a capacity of a communication network coupled to the single device.

5. The method as recited in claim 1, wherein the encoding is carried out utilizing a first encoder.

6. The method as recited in claim 5, wherein the transcoding is carried out utilizing a decoder and a second encoder.

7. The method as recited in claim 1, wherein the first format includes a wavelet-based format.

8. The method as recited in claim 1, wherein the second format includes a DCT-based format.

9. The method as recited in claim 8, wherein the second format includes an MPEG format.

10. A single device for compressing data, comprising:

an encoder embodied on a single device for encoding data to generate first compressed data in a first format; and

a transcoder embodied on the same single device as the encoder for transcoding the first compressed data to generate second compressed data in a second format.

11. The single device as recited in claim 10, wherein the encoding occurs in real-time.

12. The single device as recited in claim 10, wherein the transcoding occurs off-line.

13. The single device as recited in claim 10, wherein the first compressed data is transcoded to generate the second compressed data in the second format such that the second compressed data is adapted to match a capacity of a communication network coupled to the single device.

14. The single device as recited in claim 10, wherein the encoding is carried out utilizing a first encoder.

15. The single device as recited in claim 14, wherein the transcoding is carried out utilizing a decoder and a second encoder.

16. The single device as recited in claim 10, wherein the first format includes a wavelet-based format.

17. The single device as recited in claim 10, wherein the second format includes a DCT-based format.

18. The single device as recited in claim 17, wherein the second format includes an MPEG format.
