Abstract

A system and a method are disclosed for on-screen display that indicates to the user the current point in the playback of the video within the context of the chapter delineations. The user can access a chapter selection feature that presents a preview image from each chapter along with a timeline representing the video, and an indication on the timeline of where the chapters fall along the timeline. Alternatively, short video segments replace the still images as representing the chapters for some or all of the chapters. The user can select a chapter in which to resume playing the video by selecting one of the images or video segments.

Claims

1. A method for navigating a plurality of chapters within a video, the method comprising:

presenting, during playback of a video, an on-screen display to a user, the on-screen display including a timeline having a demarcation for a beginning of each of a plurality of chapter of the video and having a marker corresponding to a current position in the video playback, and the on-screen display including at least one image from each of the plurality of chapters displayed in order in a line, wherein a focus identifier marks an image of a chapter corresponding to the current position within the video playback;

receiving a chapter skip input;

moving the at least one image from each chapter one position along the line with respect to the focus identifier, according to the chapter skip input;

resuming playback of the video at a chapter identified by the focus identifier.

2. The method of claim 1, wherein the on-screen display includes a video preview from at least one of the plurality of chapters of the video that is displayed in order in the line with the rest of the at least one images from the rest of the plurality of chapters.

3. The method of claim 1, wherein the video comprises secured media content on a flash memory device.

4. The method of claim 3, further comprising:

initiating playback of the video from the flash memory device;

reading metadata from the flash memory device;

matching the read metadata from the flash memory device with the video; and

assembling the video and the metadata in a memory structure to retrieve for playback and display.

5. The method of claim 1, wherein the metadata comprises chapter titles, chapter start times and location on the flash memory device.

6. A computer readable medium storing instructions thereon, the instructions when executed cause at least one processor to:

present, during playback of a video, an on-screen display to a user, the on-screen display including a timeline having a demarcation for a beginning of each of a plurality of chapter of the video and having a marker corresponding to a current position in the video playback, and the on-screen display including one image from each of the plurality of chapters displayed in order in a line, wherein a focus identifier marks an image of a chapter corresponding to the current position within the video playback;

receive a chapter skip input;

move the at least one image from each chapter one position along the line with respect to the focus identifier, according to the chapter skip input;

resume playback of the video at a chapter identified by the focus identifier.

7. The computer readable computer medium of claim 6, wherein the on-screen display includes a video preview from at least one of the plurality of chapters of the video that is displayed in order in the line with the rest of the at least one images from the rest of the plurality of chapters.

8. The computer readable computer medium of claim 6, wherein the video comprises secured media content on a flash memory device.

9. The computer readable computer medium of claim 8, further comprising instructions that cause the at least one processor to:

initiate playback of the video from the flash memory device;

read metadata from the flash memory device;

match the read metadata from the flash memory device with the video; and

assemble the video and the metadata in a memory structure to retrieve for playback.

10. The computer readable computer medium of claim 6, wherein the metadata comprises chapter titles, chapter start times and location on the flash memory device.

11. An apparatus for navigating a plurality of chapters within a video, the apparatus comprising:

a video screen; and

a processor, the processor configured to execute;

a chapter presentation module, the chapter presentation module for presenting, during playback of a video, an on-screen display on the video screen, the on-screen display including a timeline having a demarcation for a beginning of each of a plurality of chapter of the video and having a marker corresponding to a current position in the video playback, and the on-screen display including at least one image from each of the plurality of chapters displayed in order in a line, wherein a focus identifier marks an image of a chapter corresponding to the current position within the video playback,

a receive module for receiving a chapter skip input,

a move module for moving the at least one image from each chapter one position along the line with respect to the focus identifier, according to the chapter skip input, and

a resume module for resuming playback of the video at a chapter identified by the focus identifier.

12. The apparatus of claim 11, wherein the on-screen display includes a video preview from at least one of the plurality of chapters of the video that is displayed in order in the line with the rest of the at least one images from the rest of the plurality of chapters.

13. The apparatus of claim 11, further comprising a secured digital memory device interface, the secured digital memory device interface for receiving a secured media memory device having the video.

14. The apparatus of claim 13, wherein the processor is further configured to execute:

a playback module for initiating playback of the video from the secured digital memory device;

a reading module for reading metadata from the secured digital memory device;

a match module for matching the read metadata from the secured digital memory device with the video; and

an assembly module for assembling the video and the metadata in a memory structure to retrieve for playback and display.

15. The apparatus of claim 11, wherein the metadata comprises chapter titles, chapter start times and location on the flash memory device
