Display device and method for providing data broadcasting thereof
First Claim
1. A display device, comprising:
- a broadcasting signal receiving unit configured to receive a broadcasting signal of a channel;
a broadcasting signal separation unit configured to separate the broadcasting signal into video, audio, and data signals;
a controller configured to determine whether data broadcasting is serviced from the channel, to compare data broadcasting received at a previous time point with data broadcasting received at a present time point from the channel when the data broadcasting is serviced from the channel, and to determine whether the data broadcasting received from the channel is updated according to a result of the comparison;
a memory configured to store a first information on a channel on which the data broadcasting is serviced and a second information on a channel on which the data broadcasting is updated; and
a display unit configured to display a data broadcasting information screen generated using the first information and the second information stored in the memory,wherein the controller is configured to determine that the data broadcasting received from the channel is not updated when the two data broadcastings are the same, and to determine that the data broadcasting received from the channel is updated when the two data broadcastings are different,wherein the broadcasting signal receiving unit sequentially receives and outputs broadcasting signals of an entire channel to a control signal of the controller,wherein the data broadcasting information screen includes a channel on which the data broadcasting is serviced and an indicator corresponding to whether the data broadcasting is updated,wherein the data signals include an Application Information Table (AIT), andthe AIT includes a data service kind field that represents what kinds of broadcast programs are provided,the data broadcasting information screen further includes a plurality of service icons corresponding to the kinds of the broadcast programs, andthe plurality of service icons represent what kinds of broadcast programs are provided from each channel.

5. A method for providing data broadcasting of a display device, comprising:
-
receiving a broadcasting signal; confirming whether Application Information Table (AIT) information is included within a data signal of the received broadcasting signal; reading-out update relevant information of the data broadcasting described within the AIT information when the AIT is included within the data signal; comparing update relevant information read-out at a previous time point with the update relevant information readout at a present time point; determining that the data broadcasting is not updated when the two update relevant information are the same; determining that the data broadcasting is updated when the two update relevant information are different; generating a data broadcasting information screen that includes information on a channel on which the data broadcasting is serviced among an entire channel and an indicator corresponding to whether the data broadcasting is updated; and displaying the generated data broadcasting information screen, the AIT includes a data service kind field that represents what kinds of broadcast programs are provided, the data broadcasting information screen farther includes a plurality of service icons corresponding to the kinds of the broadcast programs, and the plurality of service icons represent what kinds of broadcast programs are provided from each channel. - View Dependent Claims (6, 7, 8)
