Abstract

Claims (25)

1. A method of creating customized menus in an embedded digital versatile disk recording system comprising:

selecting background data for generating a selected menu background;

selectively converting at least one index frame comprising an intra-frame from a recorded digital versatile disk into decompressed video data;

composing the selected menu in decompressed space from the selected background data and the decompressed video data, wherein the data for creating the background image is selected from the group of data formats consisting of Joint Picture Experts Group, Graphic Interchange File, or Bitmap data formats and is selectively extracted from one of a plurality of available sources, the plurality of available sources including the recorded digital versatile disk;

compressing the composed menu; and

recording the compressed composed menu onto the digital versatile disk.

2. The method of claim 1 , wherein selecting background data comprises copying background data from the digital versatile disk.

3. The method of claim 1 , wherein selecting background data comprises importing background data from a digital data source selected from the group consisting of optical disk drives, programmed flash memory devices, and computing appliances.

4. The method of claim 1 , wherein selecting background data comprises selecting data for creating a still background image.

5. The method of claim 1 , wherein composing the selected menu comprises composing a button for navigating to a segment on the digital versatile disk from the decompressed video data.

6. The method of claim 1 , wherein composing the selected menu comprises composing a menu page having a background and a plurality of buttons composed of index frames representing each of a plurality of segments recorded on the digital versatile disk.

7. The method of claim 1 , wherein selecting background data comprises selecting data available for download from a computer network.

8. A home digital versatile disk playback-recording system comprising:

a digital versatile disk drive for recording and playing-back information on a digital versatile disk;

a processing system for recording a menu with a selectable background image on the digital versatile disk; and

a processor and an encoder-decoder operable to:

import background image data from one of a plurality of available sources, the plurality of available sources including the digital versatile disk;

selectively convert selected index frames, each index frame comprising an intra-frame, from the digital versatile disk into decompressed video data;

compose the selected menu in decompressed space from the imported background image data and the decompressed video data;

compress the composed menu; and

record the compressed composed menu on the digital versatile disk.

9. The system of claim 8 , further comprising a memory for storing a library of user-selectable background image data.

10. The system of claim 9 , wherein the memory comprises a non-volatile memory storing a preset selection of user-selectable background image data.

11. The system of claim 8 , further comprising a port for importing the background image data from an external source.

12. The system of claim 8 , further comprising an embedded drive for importing the background image data.
