Abstract

Route information for a route from a departure location to a destination location is generated. The generated route information is displayed on a first display of a first device. User input based upon the route information displayed on the first display of the first device is received at the first device. Route media is generated at the first device in response to the received user input. The generated route media is different than the route information displayed on the display of the first device. The generated route media is transmitted from the first device to a second device. The second device includes a second display.

Claims

1. A system comprising:

a first display unit of a first device;

user input controls of the first device;

a communication module configured to transmit information from a first device to a second device;

a first controller of the first device configured to;

generate route information for a route from a departure location to a destination location, wherein the route comprises a plurality of sections,

display the generated route information on the first display,

receive user input through the user input controls based on the displayed route information,

generate, in response to the received user input and based on the route information, route media in a video format, the route media comprising a sequence of screen images for the route, the first controller further being configured to generate the route media by;

detecting that a first amount of change between screen images in a first section of the route is greater than a second amount of change between screen images in a second section of the route, and

based on detecting that the first amount of change between screen images in the first section of the route is greater than the second amount of change between screen images in the second section of the route, storing consecutive screen images for the first section of the route and storing non-consecutive screen images for the second section of the route, wherein each screen image further includes GPS information, and

transmit, by the communication module, the generated route media from the first device to a second device,

a second display unit of the second device; and

a second controller of the second device that is configured to;

receive, at the second device, the route media transmitted from the first device;

search for a playback point of the route media conformable to a current location of the second device by utilizing GPS information in the screens of the route media; and

output, on the second display of the second device, the route media from the searched playback point.

2. The system of claim 1 wherein:

the first controller of the first device is configured to receive the user input by receiving a selection of a section of the route; and

the first controller of the first device is configured to generate the route media by generating route media specific to the selected section of the route.

3. The system of claim 1 wherein the first section of the route includes an intersection and the second section of the route does not include an intersection.

4. The system of claim 1 wherein the first controller of the first device is further configured to receive global positioning system information.

5. The system of claim 4 wherein the first controller of the first device is configured to generate the route media based upon the received global positioning system information.

6. The system of claim 1, wherein the first device and the second device comprise at least one of a mobile communication terminal or a telematics terminal.

7. The system of claim 1, wherein the route information comprises a navigation map and the route media comprises a video.

8. The system of claim 1, wherein, in generating the route media, the first controller is configured to detect that a first amount of change between screen images in a first section of the route is greater than a second amount of change between screen images in a second section of the route by:

detecting a first amount of change between screens in consecutive screen images corresponding to the first section of the route;

detecting a second amount of change between screens in consecutive screen images corresponding to the second section of the route; and

determining that the first amount of change is greater than the second amount of change.

9. The system of claim 1, wherein the first controller is configured to store consecutive screen images for the first section of the route by storing the entirety of a set of screen images associated with the first section.

10. The system of claim 1, wherein the first controller is configured to store non-consecutive screen images for the second section of the route by storing a first set of screen images associated with the second section and not storing a second set of screen images associated with the second section.

11. The system of claim 1, wherein the video format of the route media is at least one of an Audio Video Interleave (AVI) video format, a Moving Picture Experts Group (MPEG) video format, or a QuickTime video format.
