Abstract

Displaying storage device-generated menus for playback includes connecting a storage device to a host capable of playing back video content, and presenting to the host a root directory through which a content selection file allows selecting video files for playback through user-storage device interaction, and, optionally, one or more service files that provide various useful information that are also playable back through user-storage device interaction. This typically further includes displaying a Main Menu that represents these files and playing Main Menu items as regular video files/contents. While the content selection file is played back, a content selection menu is generated by the storage device and displayed by the host, and each content selection menu item is playable by transmitting a playback command to the storage device rather than to the host. A storage device is also provided, which uses such method.

Claims

a controller operatively connected to the memory, the user interface, and the host interface, the controller being configured to;

send the virtual root directory to the host, via the host interface, for use by the host in generating and displaying a main menu, the main menu including one or more main menu items;

generate one or more video frames depicting a content selection menu, the content selection menu including one or more content selection menu items, wherein a particular content selection menu item corresponds to a particular stored video file that is not identified by the virtual root directory;

in response to a host request for video data related to a first main menu item selected from the one or more main menu items, send to the host a first video stream including the one or more video frames depicting the content selection menu

receive user input, via the user interface, corresponding to a user selection of the particular content selection menu item; and

after receiving the user input, send to the host, in response to the host request for data related to the first main menu item selected from the one or more main menu items, via the host interface, a second video stream, the second video stream including content of the particular stored video file corresponding to the particular content selection menu item.

2. The storage device as in claim 1, wherein the memory further stores a second root directory that identifies more video files than the virtual root directory.

3. The storage device as in claim 1, wherein the controller is further configured to, responsive to receiving user navigation input:

generate one or more second video frames, the one or more second video frames representing a graphical presentation of a modified content selection menu; and

send the one or more second video frames to the host.

4. The storage device as in claim 1, wherein one of the one or more main menu items references a training file in the memory, and wherein the controller is further configured to use the training file to generate and store at the memory a training table that associates signals received at the user interface to remote control commands associated with a remote control that is operable to control both the host and the storage device.

5. The storage device as in claim 1, wherein a second main menu item of the one or more main menu items references a selection menu distinct from the content selection menu, wherein the controller is further configured to:

generate one or more second video frames depicting the selection menu, the selection menu including one or more selection menu items, wherein a particular selection menu item corresponds to a service file stored at the memory; and

in response to a host request for second video data related to the second main menu item, send to the host, a third video stream including the one or more second video frames depicting the selection menu.

6. The storage device as in claim 5, wherein one of the service files is a training file, and wherein the controller is further configured to use the training file to generate and store a training table that associates signals received at the user interface to remote control commands associated with a remote control that is operable to control both the host and the storage device.

7. The storage device as in claim 5, wherein the controller is further configured to:

receive a second user input, via the user interface, the second user input corresponding to selection of the particular selection menu item that corresponds to the service file; and

in response to receipt of the second user input, send to the host, via the host interface, a fourth video stream in response to the host request, the fourth video stream including content of the service file corresponding to the particular selection menu item.

8. The storage device as in claim 1, wherein the controller is further configured to determine a host type of the host and to determine contents of the virtual root directory based on the host type type of the host.

9. The storage device as in claim 1, wherein the controller is further configured to automatically, after playback of the particular stored video file is completed, send to the host in response to the host request the first video stream including the one or more video frames depicting the content selection menu.

10. The storage device as in claim 1, wherein the controller provides the particular stored video file to the host responsive to receiving a password via the user interface.

11. The storage device as in claim 10, wherein the password is used per video file, per group of video files, or per user of the host.

12. The storage device as in claim 1, wherein the storage device is a Universal Serial Bus (USB) flash drive.

13. The storage device as in claim 1, wherein the user input interface includes a wireless communication interface.

14. The storage device as in claim 1, wherein the host request for the video data is received from the host in response to the host receiving a command from a remote control device associated with the host, and wherein the user interface is configured to receive the user input by detecting signals sent by the remote control device.

15. A method to provide a video stream to a host, the method comprising:

at a storage device coupled to a host capable of playing back video content, the storage device including;

a memory to store content, the content including a plurality of video files;

a user interface to receive user input;

a host interface to communicate with the host; and

a controller operatively connected to the memory, the user interface, and the host interface,
