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 method includes receiving a broadcast signal from a management server, processing the received broadcast signal using a hospitality middleware platform embedded in the DTV, and outputting audio/video (A/V) data on the basis of the processed broadcast signal. The hospitality middleware platform may include a switching layer for switching a first layer for processing a broadcast signal based on a broadcast standard of a first region and a second layer for processing a broadcast signal based on a broadcast standard of a second region, a flexible Digital Rights Management (DRM) layer capable of being voluntarily modified, and a downloadable engine layer capable of voluntarily programming an interactive service application.

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, the method comprising:

receiving a broadcast signal from a management server;

processing the received broadcast signal using a hospitality middleware platform embedded in the DTV; and

outputting audio/video (A/V) data on the basis of the processed broadcast signal,

wherein the hospitality middleware platform includes;

a switching layer for switching a first layer for processing a broadcast signal based on a broadcast standard of a first region and a second layer for processing a broadcast signal based on a broadcast standard of a second region;

a flexible Digital Rights Management (DRM) layer capable of being voluntarily modified; and

a downloadable engine layer capable of voluntarily programming an interactive service application.

2. The method according to claim 1, wherein the switching layer includes a triple switching layer,

wherein the triple switching layer includes:

a first switching layer for switching a System Integration (SI) engine layer and a PSI engine layer;

a second switching layer for switching a Digital Video Broadcasting DVB-T/C layer and a Vestigial SideBand/Quadrature Amplitude Modulation (VSB/QAM) layer; and

a third switching layer for switching a hospitality UI layer of the first region and a hospitality UI layer of the second region.

3. The method according to claim 1, wherein the hospitality middleware platform includes a runtime library for voluntarily programming the interactive service application on the downloadable engine layer, wherein the runtime library is located close to the downloadable engine layer on the hospitality middleware platform.

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

5. The method according to claim 4, wherein the interactive service application includes an application for processing data related to a unique special service provided from the hotel.

6. A digital television (DTV) located in one independent space among a plurality of independent spaces physically separated from one another, the digital television (DTV) comprising:

a reception module for receiving a broadcast signal from a management server;

a processing module for processing the received broadcast signal using a hospitality middleware platform embedded in the DTV; and

an output module for outputting audio/video (A/V) data on the basis of the processed broadcast signal,

wherein the hospitality middleware platform includes;

a switching layer for switching a first layer for processing a broadcast signal based on a broadcast standard of a first region and a second layer for processing a broadcast signal based on a broadcast standard of a second region;

a flexible Digital Rights Management (DRM) layer capable of being voluntarily modified; and

a downloadable engine layer capable of voluntarily programming an interactive service application.

7. The digital television (DTV) according to claim 6, wherein the switching layer includes a triple switching layer,

wherein the triple switching layer includes:

a first switching layer for switching a System Integration (SI) engine layer and a PSI engine layer;

a second switching layer for switching a Digital Video Broadcasting DVB-T/C layer and a Vestigial SideBand/Quadrature Amplitude Modulation (VSB/QAM) layer; and

a third switching layer for switching a hospitality UI layer of the first region and a hospitality UI layer of the second region.

8. The digital television (DTV) according to claim 6, wherein the hospitality middleware platform includes a runtime library for voluntarily programming the interactive service application on the downloadable engine layer, wherein the runtime library is located close to the downloadable engine layer on the hospitality middleware platform.

9. The digital television (DTV) according to claim 6, wherein the independent spaces physically separated from one another correspond to several rooms contained in one hotel.

10. The digital television (DTV) according to claim 9, wherein the interactive service application includes an application for processing data related to a unique special service provided from the hotel.
