Abstract

A data receiving system includes a receiver which is configured to receive broadcast data. The broadcast data includes live information data and announcement data. The live information data has live information relating to a place. The announcement data includes a time indicator and content information regarding contents of the live information data. A determining unit is configured to determine whether newly received live information data is new or not based on the time indicator.

Claims

1. A data receiving system comprising:

a receiver configured to receive broadcast data comprising;

live information data having live information relating to a place; and

announcement data including a time indicator and content information regarding contents of the live information data; and

a determining unit configured to determine whether newly received live information data is new or not based on the time indicator.

2. The data receiving system according to claim 1, wherein the time indicator includes a serial number.

3. The data receiving system according to claim 1, further comprising:

a data control unit configured to delete incomplete data which has not been received completely yet if the data control unit determines that the incomplete data is not currently broadcasted.

4. The data receiving system according to claim 1, further comprising:

a data controller configured to determine by checking the time indicator whether broadcast data currently being received is already received data which had been received; and

a receiving controller configured to control the receiver to receive the broadcast data if the data controller determines that broadcast data currently being received is not the already received data.

5. The data receiving system according to claim 1, wherein the announcement data further comprises:

at least one of activation time and expiring time with respect to the live information data.

6. The data receiving system according to claim 5, further comprising:

a display controller configured to control a display to show one live information data on or after the activation time of said one live information data.

7. The data receiving system according to claim 5, further comprising:

a display controller configured to control a display not to show one live information data on or after the expiring time of said one live information data.

8. The data receiving system according to claim 5, further comprising:

a data controller configured to delete one live information data on or after the expiring time of said one live information data.

9. The data receiving system according to claim 1, further comprising:

a data updating unit configured to update an updated portion of data stored in the data receiving system.

10. The data receiving system according to claim 1, further comprising:

a decoding unit configured to decode the live information data from a beginning or in a middle of the live information data when the data receiving system was turned off in the middle of the live information data while being decoded.

11. The data receiving system according to claim 1, wherein the data receiving system includes a navigation system.

20. The data receiving system according to claim 1, wherein the live information data varies on a daily basis or by minute.

21. The data receiving system according to claim 1, wherein the live information data includes a title of a movie or show time of a movie.

12. A data broadcasting system comprising:

a broadcast data generator configured to generate broadcast data comprising;

live information data having live information relating to a place; and

announcement data including content information regarding contents of the live information data and a time indicator based on which a system receiving the broadcast data determines whether newly received live information data is new or not; and

a broadcasting device configured to broadcast the broadcast data.

13. The data broadcasting system according to claim 12, wherein the time indicator includes a serial number.

14. The data broadcasting system according to claim 12, wherein the announcement data further comprises:

at least one of activation time and expiring time with respect to the live information data.

15. The data broadcasting system according to claim 14, wherein the broadcasting device is configured to start broadcasting the broadcast data on or before the activation time of the broadcast data or configured to stop broadcasting the broadcast data on or before the expiring time of the broadcast data.

16. The data broadcasting system according to claim 12, further comprising:

a divider configured to divide the live information data based on geographical areas.

17. The data broadcasting system according to claim 12, further comprising:

a data updating unit configured to update a portion of the live information data, the broadcasting device being configured to broadcast the updated portion of the live information data.

18. A data receiving system comprising:

receiver means for receiving broadcast data comprising;

live information data having live information relating to a place; and

announcement data including a time indicator and content information regarding contents of the live information data; and

determining means for determining whether newly received live information data is new or not based on the time indicator.

19. A data broadcasting system comprising:

broadcast data generator means for generating broadcast data comprising;

live information data having live information relating to a place; and

announcement data including content information regarding contents of the live information data and a time indicator based on which a system receiving the broadcast data determines whether newly received live information data is new or not; and

broadcasting means for broadcasting the broadcast data.

22. A data receiving method comprising:

receiving broadcast data including;

live information data having live information relating to a place; and

announcement data including a time indicator and content information regarding contents of the live information data; and

determining whether newly received live information data is new or not based on the time indicator.

23. A data broadcasting method comprising:

generating broadcast data including;

live information data having live information relating to a place; and

announcement data including content information regarding contents of the live information data and a time indicator based on which a system receiving the broadcast data determines whether newly received live information data is new or not; and

broadcasting the broadcast data.
