The power management IC 25 can charge the battery from both the USB base and the AC adapter base, and performs battery charging and power supply.

  In FIG. 1, the processor 21 and the storage device 22 in the configuration of the HDMI dongle 20 of FIG. 2 are shown as a control unit 21A and a storage unit 22A. The control unit 21A includes first display control means 71, second display control means 72, second display control means 73, detection means 74, and travel time changing means 75. The first display control means 71 is for displaying a web page as content on the television screen.

  The detecting means 74 detects the frame of the selection target information to be displayed next in accordance with the operation of the direction key for selecting the selection target information existing in the web page (content) and displaying the frame in focus. To do. Here, the direction key is a key for instructing a frame of selection target information to be focused next, and can indicate an up / down / left / right direction. This direction key can be constituted by a so-called cross key 81 provided on the television remote controller 80. The selection target information refers to a tag having information for designating a link destination such as an anchor tag.

  The second display control means 72 changes and displays the focus display from the movement source frame currently focused on display to the movement destination frame detected by the detection means 74 based on the operation of the direction key. The third display control means 73 displays a movement locus based on the position information of the movement source frame and the position information of the movement destination frame when the focus display is changed by the second display control means 72. Is. The moving time changing means 75 changes the time for the sequential change. The above means can be realized by the processor 21 executing a program (web browser) in the storage device 22.

  As a main configuration of the television 10, a control unit 11, an input switching unit 12, a video display unit 13, and a receiving unit 14 are shown. The video display unit 13 displays video on the screen using video data (video signal) that arrives via the input switching unit 12. The input switching unit 12 switches video data input. Here, the input switching unit 12 indicates switching between the HDMI dongle 20 and the antenna, but other input may be selected.

  The control unit 11 performs switching control of the input switching unit 12 and includes an interface function for connecting to the HDMI dongle 20 by HDMI-CEC. In this embodiment, a signal transmitted by operating the television remote controller 80 is transmitted as data based on HDMI-CEC. When the control unit 11 receives an HDMI-CEC input switching command from the HDMI dongle 20, the control unit 11 controls the input switching unit 12 to select video data sent from the HDMI dongle 20 and display it on the video display unit 13. To work.

  In the display system having the above-described configuration, video data to be displayed on the television 10 that is a video display device can be stored in the storage unit 22A. In this embodiment, as shown in the flowchart shown in FIG. 3, the processing operation of the focus display by the control unit 21A is performed.

  The control unit 11 receives a display request for a predetermined web page from the TV remote controller 80 after the power is turned on, and sends a display request for the predetermined web page to the HDMI dongle 20. In response to this, when receiving an HDMI-CEC input switching command from the HDMI dongle 20, the control unit 11 selects the video data sent from the HDMI dongle 20 and displays it on the video display unit 13. The unit 12 is switched.

  Upon receiving the display request for the predetermined web page, the control unit 21A starts the program of the flowchart of FIG. 3, accesses the web page set by the predetermined process, obtains video data composed of HTML or the like, and receives the television data. 10 and displayed (S11). The URL of this web page may be input by the TV remote controller 80, and can be preset in the HDMI dongle 20.

  Next, the control unit 21A monitors whether or not the operation of the cross key 81 has been performed (S12). When the operation of the cross key 81 is detected, the control unit 21A detects the frame of the selection target information to be focused next (S13). For example, detection is performed as follows in response to the operation of the cross key 81. By the key operation indicating the up and down direction of the cross key 81, a frame that is closest to or directly above the selection target information that exists above or below the currently focused frame is detected. Further, the nearest frame is detected from the selection target information existing on the left side or the right side of the currently focused frame by the key operation indicating the left / right direction of the cross key 81. If the selection target information does not exist on the straight left side or the straight right side, the next line is detected.

  Next, a movement trajectory is created using the position information and shape information of the movement source frame currently focused and displayed, and the position information and shape information of the movement destination frame detected above (S14). For example, as shown in FIG. 4, when there are square frames above and below, the four corners of the movement source frame 41 and the four corners of the movement destination frame 42 are connected, and the movement source along the four line segments. The rectangle can be shaped into the movement locus 43 so that the rectangle of the frame 41 changes to the rectangle of the movement destination frame 42. Also, as shown in FIG. 5, when there are square frames on the left and right, a rectangle determined by a line segment connecting each corner of the movement source frame 44 and each corner of the movement destination frame 45 is used as the shape of the movement track 46. This can be moved continuously. Note that the shape of the frame and the movement trajectory may be a circle or a polygon other than the rectangle, and is not limited.

  Next, the movement trajectory is displayed, then the movement destination frame is displayed in focus, and the focus display of the movement source frame is stopped (S15). FIG. 6 shows an example in which there are two destinations. In this case, since the focus display is moved between the movement source frame 51 and the movement destination frame 52 in one movement destination frame 52, the movement locus 53 is displayed, and the second movement destination frame 54 is displayed in the second movement destination frame 54. Since the focus display is moved between the movement source frame 52 and the movement destination frame 54, the movement locus 55 can be displayed. Further, as shown in FIG. 7, the focus display may be moved to a plurality of (here, two) destination frames 57 and 58 that partially overlap the source frame 56. In this case, the overlapping movement trajectories 59A and 59B can be displayed. As described above, the reason why a plurality of destination frames are generated is that there are line breaks in HTML in the selection target information, there are cases where there are a plurality of link destinations, and there are a plurality of elements in the selection target information. This is because there may be a plurality of frames.

  In the display of the movement track in step S15, the third display control means 73 can display the color and / or luminance / density on the movement track by sequentially changing them. In other words, by changing the color sequentially from the source frame side to the destination frame and / or changing the brightness / density sequentially (brightness / density on the source frame side), etc. Can be pointed out.

  Further, the movement trajectory can be composed of a large number of figures, and can be displayed in a discontinuous and sequential manner in addition to the continuous display from the movement source frame side toward the movement destination frame. Specifically, as shown in FIG. 8, rectangular movement trajectories 49A, 49B, and 49C (three are examples) are created from the movement source frame 47 to the movement destination frame 48, and 49A → It is possible to discontinuously display 49B → 49C. This also indicates in which direction the destination frame is located.

  The moving time changing means 75 of the control unit 21A changes the change time sequentially. For example, a predetermined operation of the TV remote control 80 is used to change the time mode of the sequential change. For example, one of several preset times is selected, or continuous time is displayed as a bar, and the length of the bar is set. It may be possible to change and set. Thereby, it is possible to set the time of sequential change according to the ability of the operator. Further, the time for moving the focus display may be switched corresponding to this set time or by another setting.

The television 10A includes the control unit 21A and the storage unit 22A configured by the HDMI dongle 20 in the television 10 of FIG. In addition, a communication interface 31 for connecting to the network 30 is provided.

  In this configuration, the control unit 11 receives a display request for a predetermined web page from the TV remote controller 80 after the power is turned on, and sends a display request for the predetermined web page to the control unit 21A. Upon receiving the display request for the predetermined web page, the control unit 21A starts the program of the flowchart of FIG. 3, accesses the web page set by the predetermined process, and obtains video data composed of HTML or the like. Send to control unit 11.

  The control unit 11 switches the input switching unit 12 so that the video data sent from the control unit 21A is selected and displayed on the video display unit 13, and the web page is displayed on the video display unit 13. Also in this embodiment, the first display control means 71, the second display control means 72, the second display control means 73, the detection means 74, and the travel time changing means 75 provided in the control unit 21A are described above.
