Abstract

A digital broadcast receiver and a control method thereof are disclosed. The digital broadcast receiver includes a reception unit for receiving a broadcast signal which mobile service data and main service data are multiplexed, an extractor for extracting transmission parameter channel signaling information and fast information channel signaling information from a data group in the received mobile service data, an acquirer for acquiring a program table describing virtual channel information and a service of an ensemble by using the extracted fast information channel signaling information, the ensemble being a virtual channel group of the received mobile service data, a detector for detecting a descriptor defining Internet access information corresponding to the mobile service data by using the acquired program table, and a controller for controlling such that the Internet access information of the detected descriptor and the mobile service data are displayed.

Claims

1. A method of processing data in a transmitting system, the method comprising:

encoding first broadcast data for a first service;

encoding first signaling data;

mapping the encoded first broadcast data and the encoded first signaling data into a data unit that has a first region, a second region, and a third region; and

transmitting a broadcast signal including the data unit,

wherein the data unit further includes second signaling data,

wherein the first signaling data include version information for indicating change in the second signaling data,

wherein the second signaling data include information for rapid acquisition of the first service,

wherein the second region is positioned between the first region and the third region, and

wherein known data are transmitted in the second region except the first region and the third region.

2. The method of claim 1, wherein the known data are spaced regularly in the second region of the data unit.

3. The method of claim 1, wherein the broadcast signal further includes second broadcast data for a second service other than the first service.

4. The method of claim 1,

wherein the broadcast signal further includes third signaling data, and

wherein the third signaling data include location information of the first broadcast data when the first broadcast data are provided via the Internet.

5. The method of claim 4, wherein the location information corresponds to uniform resource locator (URL).

6. A transmitting system for processing data, the transmitting system comprising:

a first encoder for encoding first broadcast data for a first service;

a second encoder for encoding first signaling data;

a formatter for mapping the encoded first broadcast data and the encoded first signaling data into a data unit that has a first region, a second region, and a third region; and

a transmitting unit for transmitting a broadcast signal including the data unit,

wherein the data unit further includes second signaling data,

wherein the first signaling data include version information for indicating change in the second signaling data,

wherein the second signaling data include information for rapid acquisition of the first service,

wherein the second region is positioned between the first region and the third region, and

wherein known data are transmitted in the second region except the first region and the third region.

7. The transmitting system of claim 6, wherein the known data are spaced regularly in the second region of the data unit.

8. The transmitting system of claim 6, wherein the broadcast signal further includes second broadcast data for a second service other than the first service.

9. The transmitting system of claim 6,

wherein the broadcast signal further includes third signaling data, and

wherein the third signaling data include location information of the first broadcast data when the first broadcast data are provided via the Internet.

10. The transmitting system of claim 9, wherein the location information corresponds to uniform resource locator (URL).
