Abstract

A digital broadcasting system and a method for processing data in the same are disclosed. A method for controlling a digital television (DTV) located in one independent space among a plurality of independent spaces physically separated from one another is disclosed. The DTV includes an access point (AP) card. The method includes receiving guest information recorded in a storage area of a compact wireless device and a wired equivalent privacy (WEP) key value of the AP card, receiving the WEP key value corresponding to the AP card of the DTV from a management server, comparing the WEP key value received from the compact wireless device with the WEP key value received from the management server, switching an operation mode of the DTV from a power-off mode to a wake mode, if the WEP key values are identical to each other, and controlling at least one guest information received from the compact wireless device to be displayed.

Claims

1. A method for controlling a digital television (DTV) located in one independent space among a plurality of independent spaces physically separated from one another, wherein the DTV includes an access point (AP) card, the method comprising:

receiving guest information recorded in a storage area of a compact wireless device and a wired equivalent privacy (WEP) key value of the AP card, wherein the AP card generates a predetermined unique WEP key value by combining at least one of a independent space identification information;

receiving the WEP key value corresponding to the AP card of the DTV from a management server;

comparing the WEP key value received from the compact wireless device with the WEP key value received from the management server;

switching an operation mode of the DTV from a power-off mode to a wake mode, if the WEP key values are identical to each other; and

controlling at least one guest information received from the compact wireless device to be displayed, wherein the guest information to be displayed is customized content to only the guest,

wherein the AP card includes middleware to drive a variety of applications provided to the guest and supports the multi-protocol interface to control devices of respective independent spaces.

2. The method according to claim 1, wherein the storage area of the compact wireless device corresponds to a radio frequency identification (RFID) tag or a memory of a wireless LAN (WLAN).

3. The method according to claim 2, wherein the DTV includes an RFID reader,

wherein the RFID reader is installed at the interior or exterior of the DTV, and is mapped to the RFID tag of the compact wireless device,

if the RFID reader is located at the exterior of the DTV, the RFID reader and the AP card of the DTV are connected to each other in series.

4. The method according to claim 1, wherein the independent spaces physically separated from one another correspond to several rooms contained in one commercial building.

5. A digital television (DTV) located in one independent space among a plurality of independent spaces physically separated from one another, wherein the DTV includes an access point (AP) card, the digital television (DTV) comprising:

an interface for receiving guest information recorded in a storage area of a compact wireless device and a wired equivalent privacy (WEP) key value of the AP card, and for receiving the WEP key value corresponding to the AP card of the DTV from a management server, wherein the AP card generates a predetermined unique WEP key value by combining at least one of a independent space identification information;

a controller for comparing the WEP key value received from the compact wireless device with the WEP key value received from the management server and for switching an operation mode of the DTV from a power-off mode to a wake mode, if the WEP key values are identical to each other; and

an output module for controlling at least one guest information received from the compact wireless device to be displayed, wherein the guest information to be displayed is customized content to only the guest,

wherein the AP card includes middleware to drive a variety of applications provided to the guest and supports the multi-protocol interface to control devices of respective independent spaces.

6. The digital television (DTV) according to claim 5, wherein the storage area of the compact wireless device corresponds to a radio frequency identification (RFID) tag or a memory of a wireless LAN (WLAN).

7. The digital television (DTV) according to claim 6, wherein the DTV includes an RFID reader, wherein the RFID reader is installed at the interior or exterior of the DTV, and is mapped to the RFID tag of the compact wireless device, and if the RFID reader is located at the exterior of the DTV, the RFID reader and the AP card of the DTV are connected to each other in series.

8. The digital television (DTV) according to claim 5, wherein the independent spaces physically separated from one another correspond to several rooms contained in one commercial building.
