Apparatus and method for displaying channel information in digital broadcasting receiver

A method of displaying channel information of a plurality of channels in a digital broadcasting receiver, the method comprising:

• receiving a broadcasting signal;
• receiving a signal of one of the plurality of channels selected by a user through a first tuner and simultaneously extracting channel information and a representative image for each of the plurality of channels from the broadcasting channel through a plurality of second tuners;
• and
• displaying the channel information and the representative image for each channel when the user makes a corresponding request,
• wherein the extracting of the channel information and the representative images for all the channels included in the broadcasting signal is continuously repeated in the background, and
• wherein an extraction time of the channel information and the representative image for each channel are displayed together with a present time, and
• wherein the extraction of the extraction time occurs for a predefined time period from the present time, where the predefined time period is a maximum time lag to search for the representative image for each of the channel.

A digital broadcasting receiver to receive a broadcasting signal having a plurality of channels, the receiver comprising:

• at least one first tuner to receive a signal of a selected channel of the plurality of channels selected by the user;
• at least one second tuner to extract channel information and a representative image for each of the plurality of channels from the broadcasting signal while the at least one first tuner receives the signal of the selected channel;
• a display to display the selected channel received by the at least one first tuner and to display the representative images for the each of the plurality of channels extracted by the at least one second tuner;
• and
• a controller to control the display to display the representative images based upon input from the user,
• wherein the at least one second tuner continuously repeats the extraction of channel information and the representative images included in the broadcast signal for all the channels in the background, and
• wherein the display displays an extraction time of the channel information and the representative image for each channel together with a present time, and
• wherein the extraction of the extraction time occurs for a predefined time period from the present time, where the predefined time period is a maximum time lag to search for the representative image for each of the channel.

A digital broadcasting receiver to receive a broadcasting signal having a plurality of channels, the receiver comprising:

• at least one first tuner to receive a signal of a selected channel of the plurality of channels selected by the user;
• at least one second tuner to extract channel information and a representative image for ones of the plurality of channels from the broadcasting signal while the at least one first tuner receives the signal of the selected channel;
• a display to display the selected channel received by the at least one first tuner and to display the representative images for the ones of the plurality of channels extracted by the at least one second tuner;
• and
• a controller to control the display to display the representative images based upon input from the user, wherein each second tuner is capable of extracting the channel information and the representative image for more than one channel while the at least one first tuner receives the signal of the selected channel,
• wherein the at least one second tuner continuously repeats the extraction of channel information and the representative images included in the broadcast signal for all the channels in the background,
• wherein the display displays an extraction time of the channel information and the representative image for each channel together with a present time, and
• wherein the extraction of the extraction time occurs for a predefined time period from the present time, where the predefined time period is a maximum time lag to search for the representative image for each of the channel.
