Abstract

A method for providing Digital Video Broadcasting-Handheld (DVB-H) and streaming services in a portable terminal includes receiving Electronic Service Guide (ESG) data of DVB-H and displaying a DVB-H channel, confirming whether a field associated with a streaming channel is present in a reserved field of the received ESG data, and if the associated field is present in the ESG data, displaying a steaming channel corresponding to the associated field together with the DVB-H channel.

Claims

1. A method for providing Digital Video Broadcasting-Handheld (DVB-H) and streaming services in a portable terminal, comprising:

receiving Electronic Service Guide (ESG) data of DVB-H and displaying a DVB-H channel;

confirming whether a field associated with a streaming channel is present in a reserved field of the received ESG data; and

if the associated field is present in the ESG data, displaying a steaming channel corresponding to the associated field together with the DVB-H channel.

2. The method of claim 1, further comprising

if the associated field is not present in the ESG data, confirming whether information about the streaming channel is present in a preset Wireless Application Protocol (WAP), and displaying the confirmed streaming channel together with the DVB-H channel.

3. The method of claim 1, wherein the reserved field is a <

UnicastServiceDelivery>

field or an <

Extension>

field of the ESG data.

4. The method of claim 1, further comprising

selectively displaying the streaming channel corresponding to the associated field and or DVB-H channel in response to a user request.

5. The method of claim 2, further comprising

selectively displaying the streaming channel corresponding to the associated field and or DVB-H channel in response to a user request.

6. The method of claim 1, further comprising

if a DVB-H broadcast signal is not detected for a prescribed time period, confirming a WAP page and displaying only a list of streaming channels.

7. The method of claim 6, further comprising

checking a broadcast network state at prescribed intervals, if a DVB-H broadcast signal is received, displaying a list of DVB-H channels through the ESG data together with the list of streaming channels.

8. The method of claim 1, further comprising halting the broadcast service of the DVB-H channel if the portable terminal is unable to receive signals via the DVB-H channel and displaying the signals via the steaming channel;

monitoring a DVB-H network and providing a selection to broadcast the signals via either the DVB-H channel or the steaming channel if the portable terminal reenters the DVB-H network.

9. The method of claim 8, further comprising providing a playback point of the signals when the portable terminal is unable to receive the signals via the DVB-H channel for a subsequent replay in the streaming channel.

10. A method for providing Digital Video Broadcasting-Handheld (DVB-H) and streaming services in a portable terminal, comprising:

if it is confirmed that a DVB-H broadcast signal is not received, halting a broadcast service of a DVB-H channel and generating an alert message indicating that the broadcast service of the DVB-H channel is stopped;

confirming whether information about a streaming channel associated with the service-stopped DVB-H channel is present in a reserved field of Electronic Service Guide (ESG) data; and

obtaining information about the service-stopped DVB-H channel through the confirmation in the ESG data, and receiving and displaying the streaming channel associated with the service-stopped DVB-H channel.

11. The method of claim 10, further comprising:

checking a DVB-H broadcast network at prescribed intervals while receiving and displaying the streaming channel; and

if the DVB-H broadcast signal is received, informing a user that the DVB-H broadcast signal is received and returning to the service-stopped DVB-H channel.

12. The method of claim 10, further comprising

confirming whether the information about the streaming channel associated with the service-stopped DVB-H channel is present in a preset Wireless Application Protocol (WAP) page.

13. The method of claim 12, further comprising

obtaining information about the service-stopped DVB-H channel through the confirmation in the preset WAP page, and receiving and displaying the streaming channel associated with the service-stopped DVB-H channel.

14. The method of claim 10, further comprising:

if the streaming channel associated with the service-stopped DVB-H channel is a streaming channel of a multimedia service identical to the service-stopped DVB-H channel, receiving and displaying the streaming channel from a playback point after a stopped point; and

if the streaming channel associated with the service-stopped DVB-H channel is a streaming channel of a multimedia service relating to the service-stopped DVB-H channel, receiving and displaying the streaming channel from a first playback point.

15. The method of claim 13, further comprising:

if the streaming channel associated with the service-stopped DVB-H channel is a streaming channel of a multimedia service identical to the service-stopped DVB-H channel, receiving and displaying the streaming channel from a playback point after a stopped point; and

if the streaming channel associated with the service-stopped DVB-H channel is a streaming channel of a multimedia service relating to the service-stopped DVB-H channel, receiving and displaying the streaming channel from a first playback point.

16. The method of claim 10, further comprising

if the information about the streaming channel associated with the service-stopped DVB-H channel is not confirmed, confirming whether the information about the streaming channel is present in the WAP page or in the reserved page of the ESG data, and displaying a corresponding streaming channel.

17. The method of claim 12, further comprising

if the information about the streaming channel associated with the service-stopped DVB-H channel is not confirmed, confirming whether the information about the streaming channel is present in the WAP page or in the reserved page of the ESG data, and displaying a corresponding streaming channel.

18. The method of claim 10, wherein the reserved field is a <

UnicastServiceDelivery>

field or an <

Extension>

field of the ESG data.
