Hereinafter, a control method of a broadcast receiver and a broadcast receiver employing the method will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating an embodiment of a broadcast receiver for recognizing a user according to the present invention.

Referring to FIG. 1, a broadcast receiver according to an embodiment of the present invention captures an image at a predetermined period from a mounted camera 101. At this time, the broadcast receiver captures images in a predetermined shooting range 102, detects the shape of the face of the user from the captured image, and identifies the user by comparing with a previously stored pattern.

In this case, when there are a plurality of users, after detecting the face shapes of the plurality of users, the detected users may be identified as one user group.

 2 is a flowchart illustrating a process of identifying a user and providing preferred channel information according to an embodiment of the present invention.

 In step S201, the broadcast receiver according to an embodiment of the present invention captures an image at a predetermined period from the mounted camera 101.

 Next, in step S202, the broadcast receiver detects the shape of the user's face in the captured image, and then identifies the user by comparing with the previously stored pattern.

In this case, various methods may be used as a method of detecting a user's face shape. For example, the user may recognize the user's face by recognizing an edge in the image, and identify the user by comparing and analyzing previously stored patterns and edges. can do.

When there are a plurality of users, all of the plurality of users may be detected and the users may be identified by determining whether all of the users have a registered pattern.

As a result of the determination in step S202, if the user is not identified, the broadcast receiver registers the face shape included in the image captured in step S207 as a new user, and then associates the channel information selected by the user with the new user identifier. Store in storage means. In this case, the storage means is a concept including a memory, storage, database, etc. means a means that can record and maintain data.

For example, if the detected user's face does not match the pre-stored pattern, the broadcast receiver registers the detected user as a new user, and stores the channel information selected by the new user in the storage means. Preferred channel information for each viewing time zone may be collected and stored in the storage means.

In this case, the viewing time zone may include at least one of day information and time information.

In addition, the preferred channel is a concept including not only information on a channel for providing an analog and digital broadcast signal, but also information on all video signals or contents provided from the broadcast receiver.

For example, the preference channel includes not only digital broadcast channel or analog broadcast channel information, but also information on an application or content received through the Internet.

As a result of the determination in step S202, when the user is identified, in step S203, the broadcast receiver determines whether the user selects a channel. The channel selection input may be received from a predetermined external input means (remote control, etc.) or may be received from a key input unit mounted in the broadcast receiver.

As a result of the determination in step S203, when the user selects a channel, the broadcast receiver may store the channel information selected in step S204 in the storage means in association with the identification information of the user. The stored channel information may be used to determine the user's preferred channel.

For example, the broadcast receiver may store channel information selected by the identified user in a storage means to collect preferred channel information for each viewing time zone, and update the collected preferred channel information in the storage means.

As a result of the determination in step S203, when the user does not select a channel, the broadcast receiver reads the preferred channel information of the user identified in step S205.

Referring to FIG. 3, the broadcast receiver according to an embodiment of the present invention stores preferred channel information corresponding to a viewing time zone for each day of each user 301, 302, and 303.

For example, if 'USER SET1' often selects the preferred channel 'MBC Departure Video Travel' from 12:00 to 13:00 on Monday, this information is stored in the storage means and then 'USER SET1' in that time zone. If 'is recognized, output the preferred channel' MBC departure video travel ', or output a user interface informing the corresponding channel information.

For example, if 'USER SET1' often selects 'Yahoo Widget' from 17:00 to 18:00 on Tuesday, after storing this information in the storage means, 'USER SET1' If it is recognized, it outputs a 'yahoo widget', which is a favorite channel (in this case, preferred content), or a user interface that informs the corresponding channel information.

Therefore, the broadcast receiver stores the preferred channel information selected in the viewing time zone for each user or a plurality of users using the broadcast receiver, and if the user is detected in the corresponding time zone, reads the preferred channel information and outputs the preferred channel, or prefers. By providing the channel information, the user can output the channel desired by the user without changing the channel, thereby increasing the user's convenience significantly.

For example, if you frequently watch 'SBS Animal Farms' for USER SET 1 (including USER1, USER2, and USER 3) between 10:00 and 12:00 Sunday, the broadcast receiver stores this information. After that, when 'USER SET 1' is detected at the corresponding time, 'SBS animal farm' is automatically outputted, or information on the corresponding channel is output, thereby improving user convenience.

As described above, the user identification process may be performed by capturing an image from a camera included in a broadcast receiver, detecting a face shape, and comparing a pre-stored pattern to identify a user.

In step S503, the broadcast receiver determines preferred channel information corresponding to the viewing time zone in which the current time is included.

For example, the preferred channel information corresponding to the viewing time zone including the current time is determined from the favorite channel information of the user detected by the storage unit as shown in FIG. 3.

For example, when the broadcast receiver is powered on and the identified user is 'user set 1' and the current time is 'Tuesday 17:30', the preferred channel information 'Yahoo widget' that the user prefers to watch at that time is Judge.

In step S504, the broadcast receiver outputs a broadcast signal received in the read preferred channel. For example, the broadcast receiver outputs a 'yahoo widget' (preferred channel) received by a predetermined server (preferred channel).

6 is a diagram illustrating an embodiment of outputting a preferred channel received through a preferred channel according to the present invention.

Referring to FIG. 6, when a user inputs a power-on command, the broadcast receiver identifies a user, reads preferred channel information that the user prefers to watch at the current time, and then prefers. Can output channel

For example, when the broadcast receiver is powered on and the identified user is 'user set 1' and the current time is 'Tuesday 17:30', the preferred channel information 'Yahoo widget' that the user prefers to watch at that time is After determining '(601), it may be output.

Therefore, by storing the preferred channel information selected in the viewing time zone for each user or a plurality of users using the broadcast receiver, and automatically outputs the preferred channel even if the user is not selected in the corresponding time zone even if the user does not select a separate button This has the effect of improving user convenience.
