Abstract

The present invention relates to a method of providing a content in real time and a navigation system for providing a content in real time which recognizes an allowance time for providing the content by considering a time, a distance, a road straightness from a current guide point to a subsequent guide point, receives the content from a predetermined content providing server in real time, and provides the content during the allowance time. A navigation system for providing a content in real time, the navigation system including: an allowance time recognition unit recognizing an existence of an allowance time for providing the content while navigating; a server connection unit connecting to a predetermined content providing server via a communication network; a content receiving unit receiving the content from the content providing server; and a content providing unit providing the received content during the allowance time.

Claims

1. A navigation system for providing a content in real time, the navigation system comprising:

an allowance time recognition unit computing a required time from a current guide point to a subsequent guide point by considering a distance and a road straightness from the current guide point to the subsequent guide point in association with the navigating to recognize an existence of an allowance time for providing the content while navigating when the required time is greater than a predetermined reference time, the predetermined reference time previously set depending on a predetermined category of contents to be provided; and

a content providing unit configured to start providing a content of the category upon recognizing the existence of the allowance time and to stop providing the content upon passing the allowance time, wherein the category is set by a user and the content is received from a predetermined content providing server.

2. The navigation system of claim 1, further comprising:

a server connection unit that connects to the content providing server in real time in association with the recognition of the existence of the allowance time, and the content is received from the content providing server in real time.

3. The navigation system of claim 1, wherein the category of the content which is set by the user is stored in the content providing server in association with a user identification (ID) of the user.

4. The navigation system of claim 1, wherein the content corresponds to a multimedia content comprising at least one of a text, an image, an audio, and a video.

5. The navigation system of claim 1, wherein the content providing unit provides the content by overlaying the content on a navigation screen in association with the navigating.

6. The system of claim 1, wherein the allowance time recognition unit computes the required time by considering the distance and the road straightness from the current guide point to the subsequent guide point in association with the navigating, and further by considering a speed limit corresponding at least one the current guide point and the subsequent guide point.

7. A method implemented by a navigation system for providing a content in real time, the method comprising:

computing, by an allowance time recognition unit of the system, a required time from a current guide point to a subsequent guide point by considering a distance and a road straightness from the current guide point to the subsequent guide point in association with the navigating;

recognizing, by the allowance time recognition unit, an existence of an allowance time for providing the content while navigating when the required time is greater than a predetermined reference time, the predetermined reference time previously set depending on a predetermined category of content to be provided;

providing, by a providing unit of the system, a content of the category, the providing started upon recognizing the existence of the allowance time and stopped upon passing the allowance time, wherein the category is set by a user and the content is received from a predetermined content providing server.

8. The method of claim 7, further comprising:

connecting, by a server connection unit of the system, to the content providing server in real time in association with the recognition of the existence of the allowance time,

wherein the content is received from the content providing server in real time.

9. The method of claim 7, wherein the category of the content which is set by the user is stored in the content providing server in association with a user identification (ID) of the user.

10. The method of claim 7, wherein the content corresponds to a multimedia content comprising at least one of a text, an image, an audio, and a video.

11. The method of claim 7, wherein the required time is computed by considering the distance and the road straightness from the current guide point to the subsequent guide point in association with the navigating, and further by considering a speed limit corresponding at least one the current guide point and the subsequent guide point.

12. A non-transitory computer-readable recording medium storing a program for implementing a method for providing a content in real time, the method comprising:

computing, by allowance time recognition unit of the system, a required time from a current guide point to a subsequent guide point by considering a distance and a road straightness from the current guide point to the subsequent guide point in association with the navigating;

recognizing, by the allowance time recognition unit, an existence of an allowance time for providing the content while navigating when the required time is greater than a predetermined reference time, the predetermined reference time previously set depending on a predetermined category of content to be provided; and

providing, by a providing unit of the system, a content of the category, the providing started upon recognizing the existence of the allowance time and stopped upon passing the allowance time, wherein the category is set by a user and the content is received from a predetermined content providing server.
