Abstract

A method and apparatus to display road information are provided. The method includes receiving traffic information, and displaying an image region corresponding to a link identification (ID) by a palette color corresponding to the traffic information on the basis of the received traffic information.

Claims

1. A method for an apparatus to display road information, the method comprising:

receiving by the apparatus traffic information; and

processing by the apparatus to display an image region corresponding to a link identification (ID) by a palette color corresponding to the traffic information on the basis of the received traffic information.

2. The method of claim 1, wherein the processing to display the image region comprises:

extracting speed information corresponding to the link ID from the received traffic information;

selecting a palette color matched to the extracted speed information; and

changing a color of the image region into the selected palette color.

3. The method of claim 2, further comprising storing the link ID and the selected palette color in a storage unit of the apparatus.

4. The method of claim 1, wherein the traffic information is received in real time.

5. The method of claim 1, wherein the received traffic information is transport protocol expert group (TPEG) data based on a TPEG protocol.

6. A computer-readable storage medium for storing a program to display road information, comprising instructions to cause a computer to:

receive traffic information; and

process to display an image region corresponding to a link identification (ID) by a palette color corresponding to the traffic information on the basis of the received traffic information.

7. An apparatus to display road information, the apparatus comprising:

a receiver to receive traffic information;

a speed information extractor to extract speed information of a link identification (ID) from the received traffic information;

a palette color selector to select a palette color matched to the extracted speed information; and

a display unit to change a color of an image region corresponding to the link ID into the selected palette color and to display the image region.

8. The apparatus of claim 7, further comprising a storage unit to store the link ID and the selected palette color for the link ID.

9. The apparatus of claim 7, wherein the traffic information is received in real time.

10. The apparatus of claim 7, wherein the received traffic information is transport protocol expert group (TPEG) data based on a TPEG protocol.

11. The apparatus of claim 7, wherein the apparatus is a navigation unit to provide driving information.

12. The apparatus of claim 7, wherein:

the link ID corresponds to a region having a starting point and an ending point, and

the speed information corresponds to an average driving speed of the region.
