Abstract

An apparatus and a method for displaying out-of-band information without turning on a TV or set-top box in an open cable system. A receiving unit receives an out-of-band signal transmitted from a headend and parses the signal. A storage unit stores the parsed data and a user'"'"'s display setting. A processing unit loads the user'"'"'s display setting from the storage unit and processes the data according to the user'"'"'s display setting. A control unit further processes the processed data and causes the further processed data to be displayed on an auxiliary display or main display, wherein the auxiliary display displays the further processed data in a stand-by mode state.

4. The apparatus as claimed in claim 1, further comprising a display unit which comprises the main display, the display unit displaying the parsed data or the processed data on the main display in an ON mode state.

5. The apparatus as claimed in claim 4, wherein the display unit further comprises:

a demultiplexer for splitting an in-band signal transmitted from the headend into video, audio and electronic program guide (EPG) data; and

a decoder for decompressing the video and audio;

wherein the main display displays the parsed data, the processed data or the EPG data split from the in-band signal in the ON mode state.

6. The apparatus as claimed in claim 1, wherein the parsed data or the processed data displayed on the auxiliary display includes pay-per-view channel information.

7. The apparatus as claimed in claim 1, wherein the parsed data or the processed data displayed on the auxiliary display includes emergency notification messages.

8. The apparatus as claimed in claim 1, wherein the data-displayed on the auxiliary display includes advertisement messages.

9. The apparatus as claimed in claim 1, wherein the auxiliary display comprises a front panel display.

10. An apparatus for displaying out-of-band channel information in an open cable system, the apparatus comprising:

a main display;

an auxiliary display;

a receiving unit for receiving an out-of-band signal transmitted from a headend and parsing the out-of-band signal to generate parsed data;

a storage unit for receiving the parsed data from the receiving unit and storing the parsed data and a user display setting;

a processing unit for receiving the user display setting and the parsed data from the storage unit and processing the parsed data according to the user display setting to generate processed data; and

a control unit for receiving the processed data from the processing unit, further processing the processed data to generate further processed data and causing the further processed data to be displayed on at least one of the auxiliary display and the main display, said auxiliary display displaying the parsed data or the further processed data when the apparatus is in a stand-by mode state where at least the main display is in an OFF state.

11. The apparatus as claimed in claim 10, wherein the receiving unit comprises:

a tuner for receiving the out-of-band signal transmitted from the headend;

a parser for parsing the out-of-band signal to generate out-of-band data; and

an input receiving unit for receiving an input from a user to create a user display setting for processing the out-of-band data.

12. The apparatus as claimed in claim 10, further comprising:

a point-of-deployment (POD) device for receiving the out-of-band signal from the receiving unit, decrypting the out-of-band signal and sending the out-of-band signal which has been decrypted to the receiving unit, wherein the receiving unit parses the out-of-band signal received from the POD device to generate the parsed data.

13. The apparatus as claimed in claim 10, further comprising a display unit which comprises the main display, the display unit displaying the parsed data or the further processed data on the main display in an ON mode state.
