Description

  The present invention relates to a video display device capable of generating a browsing screen by interpreting an HTML file obtained from the Internet, for example.

A TV receiver having a browser function capable of interpreting a file existing on the Internet described in HTML (Hyper Text Markup Language) and displaying a browsing screen is known. Such a TV receiver is connected to the Internet via a telephone line or Ethernet (registered trademark) after contracting with a provider in addition to the function of presenting video / audio as an original television. Thus, it is possible to browse various websites (homepages) existing on the net (see Patent Document 1).
JP-A-10-126706

  Such a TV receiver is equipped with a browser capable of browsing HTML files on the Internet, like a personal computer. However, such TV browsers do not perform browsing operations with a keyboard or mouse, unlike browsers installed on personal computers, but with the operation buttons (up button, down button, left button, right button) of the attached remote control transmitter. Button) is used to move the cursor (highlighted display) placed on the clickable object on the browse image. Here, the clickable object has a link (URL) for jumping to another Web site (homepage), a link for requesting download of an image file, and a link for jumping to another part on the same page. It is described (embedded). Then, in the TV browser, by pressing the determination button of the remote control transmitter with the cursor placed on a desired object, it is possible to transit to the link destination indicated by the object.

  However, a conventional TV receiving apparatus equipped with a TV browser generally displays a browser (browsing) screen over the entire screen, and cannot simultaneously watch a broadcast television. Further, like the Internet television disclosed in Japanese Patent Laid-Open No. 10-126706, there is a screen that uses a so-called screen splitting function, one split screen is a Web screen, and the other screen is a TV screen. In this case, the web screen is half the original size, and visibility and operability are impaired. In addition, it is conceivable to use a PIP (Picture In Picture) function to make the child screen a TV screen, but this child screen hides a part of the Web screen and impairs visibility and operability. .

  In view of the above circumstances, an object of the present invention is to provide a video display device capable of simultaneously displaying a Web screen and a TV screen without impairing the visibility and operability of the Web screen.

  In order to solve the above-described problem, the video display device of the present invention is a clickable device on which a browsing image is generated by interpreting data content obtained via a network and a cursor on the browsing image. Position determining means for determining the position of the object, and superimposing means for generating a sub-screen video by reducing the video obtained by receiving or reproducing the broadcast, and generating a superimposed video in which the sub-screen video is superimposed on the browse image And the clickable image on which the cursor is placed based on the display position of the clickable object on which the cursor is placed, the scheduled display position of the child screen image, and the size of the child screen image. It is determined whether or not it overlaps with an object, and the sub-screen image is displayed on the clickable object on which the cursor is placed So as not to overlap as much as possible, characterized by comprising: means for commanding the display position of the small picture image in the superimposing means determines the display position of the child screen video, a.

  With the above configuration, after the display position of the sub-screen video is determined so that the sub-screen video does not overlap the clickable object on which the cursor is placed as much as possible, the sub-screen video is displayed on the browse image. Therefore, the visibility and operability of the browse image are improved.

  In the video display device having the above configuration, the small-screen video may be displayed while avoiding an operation menu display area on the browse image.

  In the video display device having these configurations, the cursor may be moved onto another clickable object by operating a button on the remote controller or the operation panel. Further, in the video display device having these configurations, when the cursor is moved onto another clickable object, the overlap with the sub-screen video is re-determined, and when it is determined that they overlap, the sub-screen video is It is preferable that the display position of the small-screen image is changed so as not to overlap the clickable object on which the cursor is placed as much as possible.

  In the video display apparatus having these configurations, a plurality of locations are set in advance as the display scheduled positions of the small-screen video, and other scheduled display positions may be sequentially selected from the plurality of locations. Good. Alternatively, in the video display device having these configurations, a reference position is set as the display position of the small-screen image, and other display scheduled positions are sequentially generated by shifting the reference position by one pixel or a plurality of pixels. You may be comprised as it is.

  In addition, in the video display device configured as described above, in order to prevent the sub-screen video from overlapping the clickable object on which the cursor is placed as much as possible, the reduction ratio for determining the size of the sub-screen video is reset. It may be configured to.

  According to the present invention, there is an effect that the Web screen and the TV screen can be displayed simultaneously without impairing the visibility and operability of the Web screen.

  A digital broadcast receiver according to an embodiment of the present invention will be described below with reference to FIGS.

  The tuner 1 in the digital broadcast receiving apparatus 30 extracts a signal having a specific frequency from the high-frequency digital modulation signal including video / audio data. That is, a process of selecting one from a plurality of transponders of digital broadcasting is performed. Further, the tuner 1 includes a demodulation circuit, a deinterleave circuit, an error correction circuit, and the like, thereby demodulating the selected digital modulation signal and outputting a transport stream.

  The PID (packet ID) filter 2 separates the transport stream received from the tuner 1 into a stream such as an MPEG2 (Moving Picture Experts Group 2) video stream or an audio stream, and section data.

  The video decoder 3 decodes the encoded signal output from the PID filter 2 to obtain a quantization coefficient and a motion vector, performs inverse DCT conversion, motion compensation control based on the motion vector, and the like, and outputs video data.

  The scaler 4 receives the video data and performs a pixel thinning process or the like based on the reduction rate information given from the CPU 20 to generate a reduced TV screen. Further, the scaler 4 sets the position of the reduced TV screen in the entire screen based on the display position coordinate information given from the CPU 20.

  The audio decoder 5 decodes the encoded signal output from the PID filter 2 and further performs D / A conversion to generate an audio signal, and supplies the audio signal to an audio output unit (speaker or the like) 6.

  The section filter 9 separates the section data into PSI / SI (Program Specific Information / Service Information) and a data carousel.

  The PSI / SI processing unit 10 inputs PSI / SI and performs processing on the PSI / SI so that it can be used for EPG (Electronic Program Guide) or the like. The SI storage memory 11 stores the processing information of the SI. The data carousel reception processing unit 12 processes the data carousel separated by the section filter 9 to acquire data broadcast content, and stores it in a content buffer (not shown).

  The BML browser 13 is activated in the data broadcast display. Data display in program-linked data broadcasting is performed, for example, when it is detected that a data broadcasting display key (d key) provided on a remote control transmitter (not shown) is pressed. In data broadcasting, an attempt is first made to acquire a startup module (moduleID = 0) included in an entry component, and a screen is created based on the obtained startup document. Then, when the user operates various buttons (such as “weather forecast” and “news”) on the startup screen, the lower layer display is executed. The BML browser 13 requests a document (data) to be displayed from the content buffer. If the requested data exists, the content buffer reads the data and passes it to the BML browser 13. If there is no requested data, the data carousel reception processing unit 12 extracts it from the transport stream.

  The HTML browser 14 is a TV browser that can browse HTML files on the Internet. The HTML browser 14 is activated, for example, when a key labeled “Internet” provided on a remote control transmitter (not shown) is pressed. The Internet is a function that allows browsing various Web sites (homepages) existing on the server by connecting to the server via the communication interface 15 and a telephone line or Ethernet (registered trademark). When the HTML browser 14 (CPU 20) detects the operation of the direction buttons (up direction button, down direction button, left direction button, direction right button) of the remote control transmitter, it is placed on a clickable object on the browse image. Move the cursor (highlighted) to another clickable object. A clickable object is described with a link (URL) for jumping to another Web site (homepage), a link for requesting download of an image file, and a link for jumping to another part on the same page. Is (embedded). When the HTML browser 14 (CPU 20) detects that the determination button of the remote control transmitter is pressed, information (URL) for transitioning to the link destination indicated by the object on which the cursor is placed is displayed on the network. Send out, obtain a new HTML file, interpret it and display it on the screen.

  Here, in the BML document transmitted by data broadcasting, for example, since the position of the data broadcasting screen and the position of the reduced TV screen are defined by the L-shaped screen configuration, the data broadcasting screen is displayed on the reduced TV screen. The top object is never hidden. On the other hand, when a reduced TV screen (sub-screen image) is simply displayed on a Web screen (browsing screen) based on an HTML file acquired on the Internet, the clickable object on which the cursor is placed is hidden as described in the previous section. May end up.

  The data broadcast browsing image (data) created by the BML browser 13 or the Web screen (data) created by the HTML browser 14 is written into the frame memory 7.

  The video composition output unit (having an on-screen display function) 8 synthesizes the reduced TV screen (data) from the scaler 4 and the Web screen (data) read from the frame memory 7, and illustrates this composite video data. Not output to the display.

  The CPU 20 gives the scaler 4 the reduction rate information of the received video, and the CPU 20 itself grasps the reduction rate information. Further, the CPU 20 acquires the position information (coordinate information on the screen) of the clickable object on which the cursor is placed and the position information of the operation menu display area from the HTML browser 14. The position information of the clickable object on which the cursor is currently placed is also acquired. Further, the CPU 20 holds four pieces of position information, that is, an upper left position, an upper right position, a lower left position, and a lower right position in the area excluding the operation menu display area as the scheduled display position of the reduced TV screen (FIG. 2). ), Temporarily select one position from the four positions. Priorities of the four planned positions may be determined.

  Based on the display position of the clickable object on which the cursor is placed, the scheduled display position (one temporary selection position) of the reduced TV screen, and the size (reduction rate information) of the reduced TV screen, It is determined whether or not the reduced TV screen overlaps the clickable object on which the cursor is placed. For example, the determination may be performed by converting these three pieces of information into pixel coordinate information in an area excluding the operation menu display area. Here, as shown in FIG. 2, it is assumed that the selected scheduled display position is the upper right position of the Web screen (except for the operation menu display area). It is also assumed that the cursor is placed on a clickable object labeled “× Δ Earthquake Early Warning”. In such a display state shown in FIG. 2, the CPU 20 obtains a determination result that there is an overlap. When the determination result that there is an overlap is obtained, the CPU 20 selects another scheduled display position and executes the same processing. When the determination result that there is no overlap is obtained by these processes, display position coordinate information is generated and given to the scaler 4 so that the reduced TV screen is displayed at the planned display position. Further, when it is determined that there is an overlap at all scheduled display positions, for example, a method for selecting a display position where the number of overlapping pixels is the smallest, or a process for determining the reduced TV screen is further reduced. There is a method to repeat. You may combine both these methods.

  FIG. 3A shows a state where the cursor is placed on a clickable object labeled “× Δ Earthquake Early Warning” and the reduced TV screen is in the lower right position. When the cursor moves on another clickable object in this state, the CPU 20 executes the determination process again. FIG. 3B shows a state where the reduced TV screen has been moved to the upper right position by the determination process again.

  In the example described above, the reduced TV screen is displayed at any one of the four planned positions. However, more planned positions may be provided. For example, a reference position is defined as a display scheduled position on the reduced TV screen, and other display scheduled positions are sequentially generated by shifting the image center by one pixel or a plurality of pixels from the reference position. May be. Further, the reduced TV screen is exemplified as the sub-screen video, but the present invention is not limited to this. For example, a video reproduced by a DVD player or the like may be converted into a sub-screen video, and the sub-screen video may be superimposed on the browsing screen. Moreover, although the digital broadcast receiving apparatus is illustrated, an analog TV receiver may be used. In the above example, a frame-shaped cursor is shown. However, the present invention is not limited to this, and other types of cursors can be used.

It is a block diagram which shows the digital broadcast receiver of embodiment of this invention. It is explanatory drawing which showed the example of a Web screen when the display plan position of TV reduction screen is assumed to be an upper right position. FIGS. 9A and 9B are explanatory diagrams showing Web screen examples in which the display position of the TV reduced screen is determined so as to avoid the object on which the cursor is placed.
