Service system and method of providing service in digital receiver thereof

1. A method of processing service data at a digital receiver in a service system, the method comprising:

receiving a broadcast signal including a content and signaling information for the content from a broadcasting station, and generating first service data based on the signaling information at the digital receiver;

transmitting device information including to a first server;

receiving a group identifier (ID) by combining a service name for the first service data and three IDs included in the device information from the first server, wherein the three IDs include an original network ID, a transport stream ID, and a service ID;

transmitting a service list including the received group ID and the generated first service data to the first server at a first interval;

requesting second service data to the first server;

receiving the second service data based on a search parameter in response to the request from the first server; and

outputting a service guide based on the second service data;

wherein the second service data is configured from mixed first service data, which is transmitted from one or more digital receivers and crawled at the first server, and additional service data for the first service data transmitted from a second server at the first server, and

wherein each respective digital receiver is configured to filter out service data, which is inaccessible by each respective digital receiver, among the second service data, store service data except for the filtered service data from the second service data and configure the service guide using the stored service data.

2. The method according to claim 1 , wherein the one or more digital receivers are connected with the first server and assigned a same group ID in the service system based on the device information.

3. The method according to claim 2 , wherein the first service data and the second service data include at least one of EPG data, channel browser data and thumbnail image data.

4. The method according to claim 3 , further comprising:

requesting service list transmission approval to the first server at the first interval;

receiving a first response to the request from the first server; and

determining whether or not to transmit the service list on the basis of the first response.

5. The method according to claim 4 , further comprising:

when the first response corresponds to transmission approval rejection, changing the first interval into a second interval and re-requesting service list transmission approval to the first server at the second interval;

receiving a second response to the re-request from the first server; and

determining whether or not to transmit the service list on the basis of the second response.

6. The method according to claim 5 , wherein the filtered service data is capable of configuring the service guide if the filtered service data is linked with an accessible service data by each respective digital receiver.

7. The method according to claim 6 , wherein at least one of the first service data and the second service data includes at least one of language information, video resolution information, audio/video (AV) type information, viewing rate information and information on a presence or absence of captions, related to a corresponding program.

8. A service system comprising:

a digital receiver configured to receive a broadcast signal including a content and signaling information for the content from a broadcasting station, generate first service data based on the signaling information, transmit device information to a first server, receive a group identifier (ID) by combining a service name for the first service data and three IDs included in the device information from the first server, transmit a service list including the received group ID and the generated first service data to the first server at a first interval, and request second service data to the first server, wherein the three IDs include an original network ID, a transport stream ID, and a service ID;

wherein the digital receiver is further configured to receive the second service data based on a search parameter in response to the request from the server and output a service guide based on the received second service data,

wherein the second service data is configured from mixed first service data which is transmitted from one or more digital receivers and crawled at the first server with additional service data for the first service data transmitted from a second server at the first server, and

wherein each respective digital receiver is configured to filter out service data, which is inaccessible by each respective digital receiver, among the second service data, store service data except for the filtered service data from the second service data and configure the service guide using the stored service data.

9. The service system according to claim 8 , wherein

the one or more digital receivers are connected with the first server and assigned a same group ID in the service system based on the device information.

10. The service system according to claim 9 , wherein the first service data and the second service data include at least one of EPG data, channel browser data and thumbnail image data.

11. The service system according to claim 10 , wherein the digital receiver requests service list transmission approval to the first server at the first interval, receives a first response to the request from the first server, and determines whether or not to transmit the service list on the basis of the first response.

12. The service system according to claim 11 , wherein when the first response corresponds to transmission approval rejection, the digital receiver changes the first interval into a second interval, re-requests service list transmission approval to the first server at the second interval, receives a second response to the re-request from the first server, and determines whether or not to transmit the service list on the basis of the second response.

13. The service system according to claim 12 , wherein the filtered service data is capable of configuring the service guide if the filtered service data is linked with an accessible service data by each respective digital receiver.

14. The service system according to claim 13 , wherein at least one of the first service data and the second service data includes at least one of language information, video resolution information, audio/video (AV) type information, viewing rate information and information on a presence or absence of captions, related to a corresponding program.

15. The service system according to claim 14 , further comprising:

the first server configured to group one or more digital receivers on the basis of device information among digital receivers in the service system, transmit a group ID to each digital receiver, and store service lists received from each digital receiver which has a same group ID at a predetermined interval in a database.
