BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital broadcasting receiver, and in particular, a time when a broadcast receiver is powered on by registering a preference channel that a user wants to watch first by day or time zone in a digital broadcasting receiver. The present invention relates to a method for watching a favorite channel in a digital broadcasting receiver, in which a previously registered preferred channel is displayed first.

In general, a digital broadcast receiver called a set top box is a device configured with a TV receiver to receive various TV image data of multiple channels transmitted through a network or a satellite. Receives the digital broadcasting data compressed by the MPEG-2 transmission method, expands the compressed data, decodes the encoded data, and converts the encoded data into a standard NTSC signal to be displayed on a TV receiver.

That is, the digital broadcast receiver receives a bit-stream digital broadcast signal in a packet unit transmitted from a broadcasting station, and selects a channel selected from among the broadcast signals received by transport demux. It is configured to extract the broadcast signal, decode the extracted broadcast signal in a moving picture experts group (MPEG) -2 scheme, and display the extracted broadcast signal.

On the other hand, digital broadcasting receivers use EPG (Electronic Program Guide) information to search only the channels they prefer without having to search for numerous channels by registering the channels that users want to watch in advance over other channels. Can watch.

However, the preferred channel viewing method in the conventional digital broadcasting receiver as described above is a general method for displaying the channel information registered by the user in advance among a number of channels, and allowing the user to tune in and watch the desired channel from the displayed channel information. It does not provide the function to register and watch the preferred channel that you want to watch by time zone or day of week.

Therefore, in the preferred channel viewing method in the digital broadcasting receiver, it is expected that the user's convenience will be greatly increased if the user registers the preferred channel to watch first and the preferred channel can be viewed without special channel search. do.

Therefore, in the present invention, a digital broadcast receiver registers a preferred channel that a user prefers to watch first by day or time zone so that the registered preferred channel is displayed first when the time for which the broadcast receiver is turned on is within the corresponding time range. It is intended to provide a preferred channel viewing method in a receiver.

As described above, the present invention provides a method for watching a preferred channel in a digital broadcasting receiver, the method comprising: checking time information at power-on to check whether a preset preferred channel priority time is set; and in the case of the preferred channel priority time, a preferred channel registered at the time. Reading information, displaying the registered preferred channel information, and tuning a channel to the preferred channel to display a broadcast program of the corresponding preferred channel;

When the registered preference channel information is two or more, if the registered preference channel is two or more, configuring and displaying the channel information registered as a preference channel as a map, and one preference selected from the preference channel map Tuning a channel to display a broadcast program of a corresponding favorite channel.

In the present invention, in the method for watching a preferred channel in a digital broadcasting receiver, when a user registers a preferred channel to be preferentially watched at a specific time zone by day or time zone, and turns on the broadcast receiver in the corresponding time zone, the preferred channel registered in the above time zone is selected. By being automatically tuned and displayed, it is possible to automatically watch a channel that a user prefers without a separate channel search in a specific time zone registered by the user in advance, thereby greatly increasing convenience in use.

Hereinafter, with reference to the accompanying drawings will be described in detail the operating principle of the present invention. In the following description of the present invention, when it is determined that a detailed description of a known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. Terms to be described later are terms defined in consideration of functions in the present invention, and may be changed according to intentions or customs of users or operators. Therefore, the definition should be made based on the contents throughout the specification.

Looking at the specific technical gist of the present invention, if the time when the broadcast receiver is powered on by registering the preferred channel that the user wants to watch first by day or time zone in the digital broadcasting receiver, the previously registered preferred channel has priority. It is easy to achieve what is intended in the present invention through the technique to be displayed.

1 illustrates a detailed block configuration of a digital broadcast receiver to which an embodiment of the present invention is applied.

Referring to FIG. 1, first, the key input unit 118 and the remote controller 126 generate a key data signal according to a user's key operation and apply the generated key data signal to the controller 116. The memory unit 120 stores an operation program for the operation of the digital broadcast receiver, and stores and outputs various program information output from the tuner unit 100 under the control of the controller 116.

The tuner 100 tunes and receives a bit stream of a channel corresponding to the tuning control signal of the controller 116 among the bit streams received from the terrestrial wave or satellite. The channel decoder 102 decodes the signal tuned from the tuner 100 in a manner such as VSB, QPSK, QAM, etc. according to a transmission method, and applies the demultiplexer 104 to the demultiplexer 104.

The demultiplexer 104 receives the digital stream decoded by the channel decoder 102, divides the video stream into video, audio, and additional information streams, and applies the decoded video stream to the MPEG-2 decoder 106. Then, the MPEG decoder 106 separates and decodes the broadcast signal provided from the demultiplexer 104 into an audio signal and a video signal, and then performs a predetermined signal processing process through the video / audio processing units 108 and 110 to display the TV receiver display unit ( 112) to be displayed on the screen.

The video processor 108 receives the video signal decoded and outputted from the MPEG-2 decoder 106 and converts the video signal into a displayable image signal on the screen of the display 112 of the TV receiver such as a CRT, PDP, LCD, etc. The audio processor 110 receives the audio signal decoded and output from the MPEG-2 decoder 106 and reproduces the audio signal through the audio output unit such as the speaker 114. The IR receiver 124 receives an operation command of a remote controller operated by a user and applies it to the controller 116.

The controller 116 controls the overall operation of each part of the digital broadcast receiver according to the operation program stored in the memory unit 120, and the remote controller 126 input from the key data signal from the key input unit 118 and the IR receiver 124. According to the key data from the control signal for generating a corresponding function is generated and applied to the corresponding function. For example, the tuner 100 provides a tuning control signal for tuning a broadcast channel selected by a user, and generates a decoding control signal for decoding the tuned broadcast signal.

In addition, the controller 116 receives and stores a preferred channel that a user wants to watch first in a specific time zone for each day or time zone according to an embodiment of the present invention, checks the time information of the broadcast receiver, and registers the preferred channel in the above time zone. After displaying the information, if there is one registered favorite channel information, it is automatically tuned and displayed. If there is more than 2 registered preferred channel information, it is automatically tuned to the selected channel by the user and displayed. In addition, the user can automatically watch their favorite channel without searching for a channel at a specific time registered in advance.

FIG. 2 is a flowchart illustrating an operation control for displaying a preferred channel registered for each day of the week in a digital broadcasting receiver according to an embodiment of the present invention. Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 and 2.

First, in accordance with the present invention, the user sets the preferred channel priority time by specifying in advance the preferred channel information for the first day or the time zone in the digital broadcasting receiver that he / she wants to watch on another channel.

At this time, the preferred channel priority time setting can be set in combination with the day of the week and time, for example, Monday 20: 00-22: 00, Saturday 14: 00-16: 00. have.

When the preferred channel priority time is set as described above, the digital broadcasting receiver stores the preferred channel priority time and checks whether the current time is included in the set time when the power is turned on and displays the preferred channel registered by the user.

That is, when the receiver power-on request by the user is input in the preferred channel priority time set as described above, the digital broadcast receiver controller 116 turns on the power of the receiver in step S200 and the current time in step S202. Check.

Subsequently, the controller 116 checks whether the time checked when the receiver is powered on in step S204 is included in the preferred channel priority time range preset by the user.

At this time, if the time checked when the receiver is turned on is not included in the preferred channel priority time range preset by the user, the controller 116 proceeds to step S206 to automatically display the channel that the user last watched. To display the display.

On the other hand, if it is checked that the time checked when the receiver is powered on is included in the preferred channel priority time range preset by the user, the controller 116 proceeds from step S204 to step S208. Preferred channel information that is registered for viewing at the priority time is read.

At this time, the preferred channel information registered in the preferred channel priority time may be registered in one or two or more according to the user's selection.

Accordingly, the controller 116 checks whether two or more preferred channels registered by the user are registered in step S210, and when two or more preferred channels registered for viewing at the preferred channel priority time are registered. In step S212, as shown in FIG. 3, two or more registered favorite channel information is configured and displayed as a channel map.

Subsequently, the controller 116 selects and inputs channel information to be viewed by the user from among the preferred channels displayed on the channel map in step S214, and selects the preferred channel selected by the user in step S216 to correspond to the preferred channel. To display the broadcast program received.

However, if the result of the check in step S210 is that there are two or less preferred channels registered by the user, the controller 116 proceeds to step S218 to check whether there is one registered preferred channel, and the preferred channel priority time. If there is only one preferred channel registered in step S220, the controller proceeds to step S220 to display the registered preferred channel information, and automatically tunes to the corresponding preferred channel to display a broadcast program received through the corresponding preferred channel.

As described above, in the present invention, in the preferred channel viewing method in the digital broadcasting receiver, when the user registers the preferred channel to be preferentially watched in a specific time zone by day or time zone, and turns on the broadcast receiver in the corresponding time zone, By allowing the registered preferred channel to be automatically tuned and displayed, it is possible to automatically watch the channel of the user's favorite without a separate channel search in a specific time zone registered by the user.
