Abstract

A method and apparatus for storing uncompressed and compressed multimedia content on a storage device, the uncompressed content is stored in an interim buffer of the storage device. Compression of uncompressed content stored in the interim buffer is done as a background task, storing the compressed content in a long term buffer of the storage device, responsive to a user request to record the multimedia content. Automatically stream the uncompressed multimedia content remaining in the interim buffer directly to a rendering device once the compressed multimedia content stored in the long term buffer has been streamed to the rendering device.

Claims

1. A multimedia apparatus comprising:

a mass storage device to store uncompressed and compressed multimedia content; and

compression logic executed by a processor, said compression logic configured to;

store uncompressed multimedia content in an interim multimedia buffer on said mass storage device,

compress said uncompressed multimedia content stored in said interim multimedia buffer as a background task to generate compressed multimedia content responsive to a user request to record said multimedia content,

store said compressed multimedia content in long term multimedia buffer on said mass storage device, and

automatically stream said uncompressed multimedia content remaining in said interim multimedia buffer directly to a multimedia rendering device once said compressed multimedia content stored in said long term multimedia buffer has been streamed to said rendering device.

2. The multimedia apparatus as in claim 1 wherein said compression logic is further configured to:

stream said compressed multimedia content from said long term multimedia buffer to a decompression module and then to a multimedia rendering device responsive to a user request to view said multimedia content.

3. The multimedia apparatus as in claim 1 wherein said multimedia content is broadcast video content.

4. The multimedia apparatus as in claim 3 wherein said broadcast video content is transmitted from a cable television provider.

5. The multimedia apparatus as in claim 3 wherein said broadcast video content is a Webcast transmitted over a data network.

6. A computer-implemented method for decreasing the cost of a multimedia storage device comprising:

storing multimedia content in an interim multimedia buffer on a mass storage device before compressing said multimedia content;

compressing said multimedia content stored in said interim multimedia buffer as a background task to generate compressed multimedia content responsive to a user request to record said multimedia content;

storing said compressed multimedia content in long term multimedia buffer on said mass storage device; and

automatically streaming said uncompressed multimedia content remaining in said interim multimedia buffer directly to a multimedia rendering device once said compressed multimedia content stored in said long term multimedia buffer has been streamed to said rendering device, if any uncompressed multimedia content remains in said interim data buffer when said long term storage buffer is empty.

7. The method as in claim 6 further comprising streaming said compressed multimedia content from said long term multimedia buffer to a decompression module and then to a multimedia rendering device responsive to a user request to view said multimedia content.

8. The method as in claim 6 wherein said multimedia content is broadcast video content.

9. The method as in claim 8 wherein said broadcast video content is transmitted from a cable television provider.

10. The method as in claim 8 wherein said broadcast video content is a Webcast transmitted over a data network.
