Abstract

An apparatus for receiving an adaptive broadcast signal and method thereof are disclosed. The present invention includes linking an IP network, sending network environment information for a receiver and program selection information to a service provider via the linked IP network, and providing the receiver with at least one service in available service information for a program selected by a user based on the sent network environment information.

Claims

1. A method of receiving an adaptive broadcast signal comprising the steps of

validating an IP network;

sending network environment information of a receiver and service selection information to a service provider via the validated IP network; and

receiving at least one media service among available media services of a selected service that is transmitted from the service provider according to the network environment information.

2. The method of claim 1, wherein the network environment information comprises network speed information.

3. The method of claim 1, wherein the network environment information comprises user level information according to a billing system.

4. The method of claim 1, wherein in the step of sending the network environment information of the receiver and the service selection information to the service provider, a data structure representing the network environment information of the receiver as at least one selected from the group consisting of a code value (code_value) field and a text field is sent to the service provider.

5. The method of claim 1, further comprising the step of deciding a contents version to be sent to the broadcast receiver in a manner of comparing the network environment information to contents information.

6. The method of claim 5, wherein at least one contents version is decided for the selected service and then provided to the broadcast receiver.

7. The method of claim 1, wherein a broadcast content that is encoded at a bit rate suitable for the network environment information of the broadcast receiver is provided to the broadcast receiver.

8. The method of claim 7, wherein broadcast content to be provided to the broadcast receiver is decided by the service provider among broadcast contents encoded at the various bit rate according to a category of a data rate.

9. An adaptive broadcast receiver comprising:

a network interface unit transceiving a broadcast stream capsulated into an IP packet by connecting the broadcast receiver to a service provider via a network;

a control unit controlling contents encoded at a bit rate suitable for a network environment of the broadcast receiver to be received in a manner of sending network environment information of the broadcast receiver to the service provider via the network interface unit; and

a display unit outputting the received broadcast stream.

10. The adaptive broadcast receiver of claim 9, wherein the network environment information comprises network speed information.

11. The adaptive broadcast receiver of claim 9, wherein the network environment information comprises user level information according to a billing system.

12. The adaptive broadcast receiver of claim 9, wherein the network environment information is sent as a data structure to the service provider and wherein the data structure represents the network environment information as at least one selected from the group consisting of a code value (code_value) field and a text field.

13. The adaptive broadcast receiver of claim 9, further comprising an IP manager unit managing a packet delivery to a destination from a source for a packet received via the network interface unit and a packet sent by the broadcast receiver.

14. The adaptive broadcast receiver of claim 9, further comprising:

a service discovery manager providing information necessary to select the service provider providing a service; and

a service control manager responsible for a selection and control of the service.
