4 is a flowchart illustrating a representative video providing method of video broadcasting in a broadcast receiving device according to an embodiment of the present invention. The representative video providing method of video broadcasting in the broadcast reception device according to an embodiment of the present invention may be applied to the broadcast reception device according to the embodiment of the present invention described with reference to FIGS. 2 and 3. Hereinafter, a method of providing a representative image of video broadcasting in a broadcast reception device according to an embodiment of the present invention and an operation of the broadcast reception device for implementing the same will be described in detail with reference to the accompanying drawings.

A specific broadcast channel for providing a video broadcast is selected [S400]. For example, the user may select a specific broadcast channel for providing video broadcast through a user interface (UI) provided by the broadcast reception device.

The controller 150 receives a video broadcast from the selected specific broadcast channel through the broadcast receiving unit 100 [S411], and buffers a buffered period including a past viewpoint and a current viewpoint for the received video broadcast. While receiving the buffer [S412], the received video broadcast is output [S413]. Steps S411 to S413 may be performed with a predetermined time difference or may be simultaneously performed [S410]. That is, the steps S411 to S413 may be simultaneously performed at a specific time.

In step S412, the controller 150 may perform the buffering using the first memory 141. The buffering period may vary according to the capacity of the first memory 141. In addition, the buffering period may be set to a specific capacity within a range allowed by the capacity of the first memory 141.

In step S413, the controller 150 may display the received video broadcast on the display unit 120 or output through a speaker so as to match the characteristics of the received video broadcast.

The controller 150 displays the plurality of representative images representing a part or the entirety of the buffering section on the display unit 120 in a time order [S420]. For example, the step S420 may be performed by the user pressing a specific key provided in the input unit 110. When the broadcast receiving device is the TV 12, the user may press the specific key of the remote controller to display the plurality of representative images.

The plurality of representative images may be extracted at predetermined time intervals among image frames included in the buffering section. The plurality of representative images may be extracted from image frames constituting the buffering section.

A time point at which the plurality of representative images are extracted may also vary.

For example, the plurality of representative images may be extracted in advance in the buffering process [S412] and stored in the first memory 141 or the representative image storage unit 143b. When the plurality of representative images are stored in the first memory 141, since the first memory 141 serves as a buffer, the plurality of representative images may be deleted when a predetermined time elapses. In addition, when the plurality of representative images are stored in the representative image storage unit 143b, the plurality of representative images are not deleted even after a predetermined time elapses. In this case, location information or playback time information corresponding to each of the plurality of representative images may be stored together with the plurality of representative images. The position information or reproduction time information is information indicating where each representative video is located in the buffering section.

Also, for example, when the controller 150 receives a specific input signal for performing the operation S420, the plurality of representative images may be extracted from image frames constituting the buffering section by a predetermined method. It may be.

The user may be provided with a plurality of representative images representing the buffering section when he / she wants to watch a past view of a video broadcast currently being viewed. Therefore, the contents of the buffering section including the past point in time and the present point in time and the overall plot can be grasped at a glance.
