For example, in a situation of recording a broadcast program, assuming that a frame transfer rate of 15 frames / 1 second, a storage area capacity of 1 second, and the number of storage areas is 15, 15 frames may be stored in one storage area. 15 frames may be sequentially stored in each of the 15 total storage areas.

In operation S501, when a storage command for a video input through the camera 121 is input, when a recording command for a broadcast signal received through the broadcast receiving module 111 is input, the wireless communication module ( It may be performed when a video is received or downloaded from an external terminal through 110.

In particular, while outputting a broadcast signal received through the broadcast receiving module 111 using the output unit 150, the user input unit 130 may receive a user operation corresponding to a broadcast recording command. In addition, the controller 180 may set a broadcast recording mode according to a user's operation corresponding to a broadcast recording command and sequentially store the frames constituting the video signal of the received broadcast signal in the storage areas described above. On the other hand, if the recording reservation is set, the controller 180 may set the broadcast recording mode at the time of the scheduled recording, and sequentially store the frames constituting the video signal of the broadcast target broadcast signal in each storage area.

In addition, one or more representative frames may exist in one storage area. More specifically, one storage area may include one or more transport stream packets (hereinafter, referred to as 'TS packets'), and the first frame of the transport flow packet located in front of a specific storage area may be a representative frame. have. For example, the representative frame may include an infra-frame ('I-frame'). Here, the I-frame is a reference frame for motion prediction / compensation when the video image is compressed or reconstructed, and thus is self-reconstructed since it is intra coded. In particular, in mobile broadcasting, one or more I-frames may exist in one second for rapid recovery when a transmission error occurs.

Hereinafter, the storage area and the stored PS packets for each storage area will be described with reference to FIGS. 6A to 6C. As described above, the storage capacity of the storage area may be set in units of time.

As illustrated in FIG. 6A, the entire storage area T_total is divided into N storage areas T_sector and managed, and a plurality of frames may be stored in each storage area. Further, in each storage area, order information, for example, Time Sector_0, Time Sector_1, Time Sector_2,..., Time Sector_ (N-1) may be set.

As shown in FIG. 6B, the storage area T_sector may include a plurality of PS packets, and the first frame of the PS packet located in front of the storage area is an I-frame. Also, PS packets with I-frames among the plurality of PS packets may be identified.

As shown in Fig. 6C, I-frames are identified and marked for each storage area, and a start frame of the storage area is always an I-frame. In addition, at least one I-frame may exist in the storage area.

Returning to FIG. 5, when the mobile terminal 100 receives a user operation corresponding to the image editing mode setting through the user input unit 130, the mobile terminal 100 sets the image editing mode using the controller 180 (S503). .

For example, the controller 180 may set the image editing mode when a menu item corresponding to the image editing mode setting is selected through a menu search or when a key for commanding the image editing mode setting is selected.

In addition, in the setting step S503, the image editing mode may be specifically set. For example, the image editing mode may include an image arrangement change mode, an image add mode, an image delete mode, and the like.

Hereinafter, a process of selecting an image editing mode through menu search in a mobile terminal will be described with reference to FIGS. 7A and 7B.

When a menu item corresponding to an image editing mode setting is selected through menu search, the mobile terminal 100 may display an image list including editable images through the display unit 151 (FIG. 7A). Here, the editable video is an image stored in the memory 160 in a storage area unit, a video photographed and stored through the camera 122, a broadcast video received and stored through the broadcast receiving module 111, It includes a video received and stored from the external terminal through the wireless communication module 110.

When 'Program A' is selected in FIG. 7A, the mobile terminal 100 may display a list of editing methods that can be performed on 'Program A' through the display unit 151 (FIG. 7B). For example, the editing method list may include changing an array, adding an image, deleting an image, and the like.

Accordingly, the mobile terminal 100 may set an image editing mode corresponding to the selected editing method from the editing method list.

Returning to FIG. 5, when the image editing mode is set by the controller 180, the mobile terminal 100 may display a representative frame for each of the storage areas in which frames constituting the image to be edited are stored. (S505).

For example, when a plurality of representative frames exist in one storage area, the most representative frame may be displayed, the most representative frame may be displayed for each TS packet, or all of the plurality of representative frames may be displayed.

Alternatively, when any representative frame among the representative frames displayed in the display step S505 is selected, the controller 180 can decode and reproduce all frames or some frames of the storage area including the selected representative frame. This is to assist the user in selecting an image to be edited.

Hereinafter, the image editing mode will be described by dividing it into an 'array change mode', an 'add image mode', and an 'image delete mode'.

First, the case where the 'array change mode' is set as the image editing mode will be described.

When the arrangement change mode is set, the mobile terminal 100 receives a storage area to be moved and a position to be moved using the representative frames displayed in the display step S505 (S507).

For example, the user selects the first and second representative frames among the displayed representative frames through a numeric key or a direction key operation, and the controller 180 moves the storage area corresponding to the first representative frame. As a storage area to be used, a previous or next position of the second representative frame may be selected as a position to be moved of the storage area corresponding to the first representative frame.

Alternatively, when the touch screen is provided with the touch screen, the controller 180 detects a touch operation on the first and second representative frames, and selects a storage area corresponding to the first representative frame as the storage area to be moved, and the second The previous or next position of the representative frame may be selected as a position to be moved in the storage area corresponding to the first representative frame. In this case, the touch operation on the first and second representative frames may include a touch drag from the first representative frame to the second representative frame, a multi-touch on the first and second representative frames, a touch and a touch on the first representative frame. After removal, the touch frame may include a touch on the second representative frame. This will be described later in detail with reference to FIGS. 8A to 8C.

Also, a plurality of storage areas to be moved may be selected by selecting a plurality of representative frames. Alternatively, when storage areas corresponding to each of the plurality of representative frames are selected as storage areas to be moved, positions to be moved for each storage area may be differently selected.

The mobile terminal 100 may move the storage area selected in the selection step S507 to the selected location (S509).

For example, when a 'first and second storage area' is selected as the storage area to be moved and 'a fifth storage area' is selected as the location to be moved, the controller 180 may select the first and second storage areas. It may be moved next (or previous) to the fifth storage area. Therefore, the first and second storage regions may be arranged in the order of the fifth storage region, the first storage region, and the second storage region (or the first storage region, the second storage region, and the fifth storage region).

Hereinafter, referring to FIGS. 8A to 8C, when the arrangement change is selected in FIG. 7B, a screen configuration for changing the arrangement between storage areas according to a user's selection will be described. Here, it is assumed that the mobile terminal 100 has a touch screen and representative frames are displayed on the touch screen.

As the arrangement change is selected in FIG. 7B, the controller 180 sets an arrangement change mode and selects a representative frame for each of the plurality of storage areas in which frames constituting the program A (see description of FIG. 7A) are stored. It can be displayed on the touch screen (FIG. 8A). In this case, the information may be displayed in order based on the order information designated in each of the storage areas.

As illustrated in FIG. 8A, the user may select a storage area to be moved by touching the first to third representative frames 151-1, 151-2, and 151-3 of the displayed representative frames. have. In addition, the user of the eighth representative frame (151-8) corresponding to the position to be moved at one point of the touched first to third representative frame (151-1, 151-2, 151-3) As the touch and drag to one point, the position to be moved can be selected. Alternatively, in order to distinguish a storage area to be moved and a touch for selecting a position to be moved, a touch count, a touch time, a touch action, a confirmation key input, or the like may be used.

In FIG. 8A, as the first to third representative frames 151-1, 151-2, and 151-3 are touch dragged to the eighth representative frame 151-8, the controller 180 controls the eighth frame 151. The first to third frames 151-1, 151-2, and 151-3 may be sequentially positioned at the next position of −8) (FIG. 8B). Therefore, the storage areas corresponding to each of the first to third frames 151-1, 151-2, and 151-3 are sequentially moved after the storage area corresponding to the eighth representative frame 151-8. Can be.

In addition, as illustrated in FIG. 8C, the controller 180 may include storage areas corresponding to each of the first to third frames 151-1, 151-2, and 151-3 as the eighth representative frame 151-8. In step S521, the storage area-specific order information may be reset as it is moved next to the storage area corresponding to the storage area. Therefore, the order information of the storage areas corresponding to the eighth representative frames before the arrangement change is reset from the eighth order to the fifth order, and the order information of the storage areas corresponding to each of the first to third representative frames before the arrangement change is determined. It may be reset to the sixth to eighth order in the first to third order.

Next, a description will be given of the case where the 'add image mode' is set as the image edit mode.

When the image adding mode is set, the mobile terminal 100 may display a list of at least one additional target image (hereinafter, 'additional target list') on the screen (S511).

For example, the addition target list may include a moving picture, a still picture, a recorded broadcast program, and the like. In addition, the list of addition targets may be displayed not only in a text format but also in a thumbnail format.

The mobile terminal 100 receives an image to be added from the list of additional images displayed in the display step S511 and receives a selection of a position to be added using the representative frames displayed in the display step S505 (S513).

In more detail with reference to the additional image selection, if a specific image is selected from the additional image list, the controller 180 converts the specific image into a TS packet to form a plurality of frames constituting the specific image at least one storage area. And a representative frame of each storage area can be displayed on the screen. Accordingly, as the user selects a representative frame among the representative frames of each of the displayed storage areas, the user may select a storage area corresponding to a portion of the specific image to be added.

As described above, an image to be added and a position to be added may be selected by using numeric keys or direction keys or touch sensing on the touch screen. In particular, the additional image and position using touch sensing of the touch screen will be described later in detail with reference to FIGS. 9A to 9E.

The mobile terminal 100 may add a storage area corresponding to the image selected in the selection step S513 to the selected location (S515).

For example, 'second and fourth storage areas' are selected as the storage areas to be added among the storage areas in which the selected image is stored, and 'sixth storage area' is among the storage areas in which the editing target image is stored as the location to be added. When selected, the controller 180 may move the second and fourth storage areas to the next (or previous) of the sixth storage area. Therefore, the sixth storage area may be arranged in the order of the sixth storage area, the second storage area, the third storage area, and the fourth storage area (or the second storage area, the third storage area, the fourth storage area, and the sixth storage area). .

Storage areas corresponding to each of -3 and 151-4 may be added to a previous (or next) location of the storage area corresponding to the sixth representative frame 151-6 (FIG. 9D).

In addition, as illustrated in FIG. 9E, the controller 180 may include storage areas corresponding to each of the second to fourth frames 151-2, 151-3, and 151-4 as the sixth representative frame 151-6. As it moves to the storage area corresponding to), the order information for each storage area may be reset (S521).

Next, a description will be given of the case where the 'image deleting mode' is set as the image editing mode.

When the image deletion mode is set, the mobile terminal 100 receives a storage area to be deleted using the representative frames displayed in the display step S505 (S517).

For example, when a user operates a numeric key or direction key or a touch on a touch screen, a storage area to be deleted may be selected. Selection of the storage area to be deleted using the touch screen will be described later in detail with reference to FIGS. 10A to 10C.

Also, a plurality of storage areas to be deleted may be selected by selecting a plurality of representative frames.

The mobile terminal 100 may delete the storage area selected in the selection step S517 under the control of the controller 180 (S519).

For example, when the 'first and second storage areas' are selected as the storage areas to be deleted, the controller 180 may delete the first and second storage areas.

Hereinafter, referring to FIGS. 10A to 10C, a screen configuration for deleting a storage area according to a user's selection when image deletion is selected in FIG. 7B will be described. Here, it is assumed that the mobile terminal 100 has a touch screen and representative frames are displayed on the touch screen.
