Abstract

An apparatus and method for providing broadcast programs. The method of providing a broadcast program in a client apparatus, includes generating final frame information identifying a frame corresponding to a broadcast watching stop time of a broadcast program that a user has been watching; transmitting the final frame information to a server that provides the broadcast program through the Internet; requesting the broadcast program from the server; receiving the broadcast program starting from a final frame searched for by the server based on the final frame information; and providing the broadcast program to the user. It is possible to provide a broadcast program from the stopped part of the broadcast program at a desired time after a user stops watching the broadcast program, even though the broadcast program is not recorded by the client apparatus.

1. A method of providing a broadcast program in a client apparatus, comprising:

generating final frame information identifying a frame corresponding to a broadcast watching stop time of a broadcast program that a user has been watching;

transmitting the final frame information to a server that provides the broadcast program, through the Internet;

requesting the broadcast program from the server;

receiving the broadcast program starting from a final frame found by the server based on the final frame information; and

providing the broadcast program to the user.

2. The method of claim 1, wherein the final frame information comprises broadcast station identification information, broadcast program identification information, and a final frame identifier.

3. The method of claim 1, wherein the final frame information comprises broadcast station identification information, broadcast program identification information, and stop time information about the broadcast watching stop time.

4. The method of claim 1, wherein the generating of the final frame information comprises generating a packet through which final frame information is transmitted by adding a final frame information identifier identifying the final frame information.

5. The method of claim 1, wherein the requesting of the broadcast program to the server comprises:

receiving a user input signal requesting the broadcast program after the user stops watching the broadcast program; and

retransmitting the final frame information through the Internet to the server according to the user input signal.

6. A method of providing a broadcast program in a server, comprising:

receiving and storing final frame information identifying a frame corresponding to a user'"'"'s broadcast watching stop time, from one or more client apparatuses;

receiving a broadcast program request signal from one of the one or more client apparatuses;

searching for a final frame of a broadcast program corresponding to the final frame information transmitted from the client apparatus; and

transmitting the broadcast program to the client apparatus starting from the final frame.

7. The method of claim 6, wherein the storing of the final frame information comprises storing the final frame information for each IP address of the one or more client apparatuses.

8. The method of claim 6, wherein the storing of the final frame information comprises storing, when the final frame information is received, the final frame information for each identifier of the final frame information.

9. The method of claim 6, wherein the searching of the final frame of the broadcast program corresponding to the final frame information comprises searching for the final frame using a final frame identifier included in the final frame information.

10. The method of claim 6, wherein the searching of the final frame of the broadcast program corresponding to the final frame information comprises searching for

the final frame based on time information including a start time and an end time of a broadcast program included in the final frame information and stop time information about a broadcast watching stop time.

11. The method of claim 6, wherein the receiving of the broadcast program request signal from the client apparatus comprises re-receiving the final frame information from the client apparatus.

12. A client apparatus to provide a broadcast program comprising:

a controller to generate final frame information identifying a final frame corresponding to a broadcast watching stop time of a broadcast program that a user has been watching; and

a communication unit to transmit the final frame information to a server that provides the broadcast program through the Internet, to request the broadcast program from the server, and to receive the broadcast program starting from a frame searched for by the server based on the final frame information.

13. The client apparatus of claim 12, wherein the final frame information comprises broadcast station identification information, broadcast program identification information, and a final frame identifier.

14. The client apparatus of claim 12, wherein the final frame information comprises broadcast station identification information, broadcast program identification information, and stop time information about the broadcast watching stop time.

15. The client apparatus of claim 12, wherein the controller generates a packet having an identifier identifying the final frame information.

16. The client apparatus of claim 12, further comprising:

a user input unit to receive a user input signal;

wherein if the user input signal requesting the broadcast program after the user has stopped watching the broadcast program is received through the user input unit, the controller controls the communication unit to re-transmit the final frame information to the server.

17. A server to provide a broadcast program to a client apparatus, the server comprising:

a communication controller to receive final frame information identifying a frame corresponding to a broadcast watching stop time from one or more client apparatuses and to receive a broadcast program request signal from one of the one or more client apparatuses;

a storage unit to store the final frame information; and

a search unit to search for a final frame of a broadcast program corresponding to the final frame information stored in the storage unit and transmitted from the client apparatus;

wherein the communication unit transmits the broadcast program starting from the final frame to the client apparatus according to the broadcast program request signal received from the client apparatus.

18. The server of claim 17, wherein the final frame information is stored in the storage unit for each IP address of the one or more client apparatuses.

19. The server of claim 17, wherein the final frame information is stored in the storage unit for each identifier of final frame information, when the final frame information is received.

20. The server of claim 17, wherein the search unit searches for the final frame using a final frame identifier included in the final frame information.

21. The server of claim 17, wherein the search unit searches for the final frame based on time information including a start time and an end time of a broadcast program included in the final frame information and stop time information about the broadcast watching stop time.

22. The server of claim 17, wherein if the final frame information is included in the broadcast program request signal, the search unit searches for the final frame information on the basis of an identifier in the final frame information.

23. A computer-readable recording medium having embodied thereon a program to execute a method of providing a broadcast program in a client apparatus, the method comprising:

generating final frame information identifying a frame corresponding to a broadcast watching stop time of a broadcast program that a user has been watching;

transmitting the final frame information to a server providing the broadcast program through the Internet;

requesting the broadcast program from the server;

receiving the broadcast program starting from a final frame searched for by the server based on the final frame information; and

providing the broadcast program to the user.

24. A computer-readable recording medium having embodied thereon a program to execute a method for providing a broadcast program in a server, the method comprising:

receiving and storing final frame information identifying a frame corresponding to a user'"'"'s broadcast watching stop time from one or more client apparatuses;

receiving a broadcast program request signal from one of the one or more client apparatuses;
