Abstract

A system for implementing personal video recording, in which integrated drive electronics are incorporated in set-top box logic, instead of with a hard disk drive. This allows the set-top box logic to communicate directly to the hard disk, so that no intervening bus is necessary.

Claims

1. A system for personal video recording, comprising:

a video memory medium; and

set-top box logic,

wherein said set-top box logic comprises integrated drive electronics that interface said set-top box logic directly with said video memory medium without a bus and without any intervening logic for processing between said video memory medium and said integrated drive electronics, both said set-top box logic and said integrated drive electronics residing on a single integrated circuit.

2. The system of claim 1, wherein said set-top box logic further comprises a central processing unit.

3. The system of claim 2, wherein said set-top box logic further comprises a local bus, such that said central processing unit and said integrated drive electronics communicate through said local bus.

4. The system of claim 1, further comprising an external memory.

5. The system of claim 4, wherein said set-top box logic further comprises a memory controller that controls access of said set-top box logic to said external memory.

6. The system of claim 1, wherein said video memory medium comprises a hard disk.

7. Set-top box logic comprising integrated drive electronics, both the set-top box logic and the integrated drive electronics integrated in a single integrated circuit, wherein said integrated drive electronics enable the set-top box logic to be directly connected to a video memory medium without a bus and without any intervening logic for processing between said video memory medium and said integrated drive electronics.

8. The set-top box logic of claim 7, wherein said set-top box logic comprises a central processing unit.

9. The set-top box logic of claim 8, further comprising a local bus, such that said central processing unit and said integrated drive electronics communicate through said local bus.

10. The set-top box of claim 7, wherein said set-top box logic comprises a memory controller that controls access of said set-top box logic to an external memory.

11. The set-top box logic of claim 7, wherein said video memory medium comprises a hard disk.
