Abstract

Disclosed is a digital television system, which comprises: a receiving module, for receiving a television signal; a parser, coupled to the receiving module, for extracting EPG (ELECTRONIC PROGRAM GUIDE) data of the television signal; a storing device, coupled to the parser, for storing the EPG data; a control signal receiving interface, for receiving a control signal from a remote control device; a processor, coupled to the storing device and the control signal receiving interface, for accessing at least a part of the EPG data according to the control signal; a display; a blender, coupled to the processor and the display, for displaying the EPG data outputted from the processor on the display; wherein the control signal comprises a channel number information.

Claims

1. A digital television system, comprising:

a receiving module, for receiving a television signal;

a parser, coupled to the receiving module, for extracting EPG (ELECTRONIC PROGRAM GUIDE) data of the television signal;

a storing device, coupled to the parser, for storing the EPG data;

a control signal receiving interface, for receiving a control signal from a remote control device;

a processor, coupled to the storing device and the control signal receiving interface, for accessing at least a part of the EPG data according to the control signal;

a display;

a blender, coupled to the processor and the display, for displaying the EPG data outputted from the processor on the display;

wherein the control signal comprises a channel number information.

2. The digital television system of claim 1, wherein the receiving module comprises:

a tuner, a demodulator, and a transport demux.

3. The digital television system of claim 1, wherein the display displays the EPG data in accordance with an order of channel number or a lineup.

4. The digital television system of claim 1, wherein the display shows a dialogue window in response to a dialogue control signal of the remote control device, and the dialogue window shows the channel number information according to the control signal.

5. The digital television system of claim 4, wherein the display displays an error message if the processor determines the channel number information incorrect.

6. The digital television system of claim 4, wherein the display stops showing the dialogue window in response to a close signal generated by the remote control device.

7. A digital television system, comprising:

a receiving module for receiving a television signal;

a parser, coupled to the receiving module, for extracting EPG (ELECTRONIC PROGRAM GUIDE) data of the digital television signal;

a storing device, coupled to the parser, for storing the EPG data;

a control signal receiving interface for receiving a control signal from a remote control device, the control signal indicating a channel number;

a processor, coupled to the storing device and the control signal receiving interface, for reading the EPG data according to the control signal and highlighting the EPG data corresponding to the channel number; and

a blender, coupled to the processor and the display, for receiving the EPG data outputted from the processor and displaying it on the display.
