  However, in the above-described prior art, the receiving terminal is set as the determination factor for determining that the user who uses the receiving terminal and the data processing device (hereinafter referred to as “receiving terminal”) cannot view the broadcast. The user confirms that the broadcast video is not output to the screen due to a specific event of the receiving terminal or the broadcast video is output to the screen even though the reception status is good because it is caused by the reception status. When it was impossible, it had the subject that it was not detected as browsing impossible.

  The specific event that the receiving terminal has here is, for example, that a broadcast video is displayed on a display screen that outputs broadcast video by outputting a display other than the broadcast video in front of the screen area displaying the broadcast video. Is an event that hinders viewing. In addition, for example, if it is assumed to be mounted as a foldable portable playback processing device, there is an event that the broadcast video cannot be seen by folding the display screen on which the broadcast video is output inside. .

  The present invention solves the above-described conventional problems, detects an event that broadcast video is not output on the screen, and an event that the user cannot confirm that the broadcast video is output on the screen, and responds to the detection result. It is an object of the present invention to provide a reproduction processing apparatus that can execute processing.

First, it is possible to detect a state in which the user of the playback processing apparatus cannot browse a part or all of the display area for displaying the broadcast video.

  According to the playback processing device of the present invention, the playback processing device may detect an event in which the playback processing device user cannot view a part or all of the display area for displaying the broadcast video regardless of the reception state. It is possible to detect and execute a predetermined process for the event.

  For example, if the power supply voltage drops and output to the display screen is restricted, or if the user cannot check the display screen due to folding of a foldable housing, the window of the broadcast video display screen Events such as when some or all of them are not output to the display screen are detected as non-viewable events, recording processing is performed at the timing according to each detection result, log recording of events that cannot be viewed, recording requests to external devices For example, it is possible to execute all processes for the user to miss a part of the broadcast video.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
The first embodiment will be described with reference to the drawings of FIGS.

  FIG. 1 is a block diagram showing a reproduction processing apparatus 100 according to Embodiment 1 of the present invention.

  In FIG. 1, the reproduction processing apparatus 100 takes in a television broadcast signal 101 to the broadcast receiving means 103 via the broadcast receiving antenna 102.

  The broadcast receiving means 103 selects and detects a predetermined channel from the received television broadcast signal, demodulates it and converts it into a stream signal (eg MPEG-TS) effective for broadcast reproduction, and a stream decoder (eg MPEG). -TS decoder) 104.

  The stream decoder 104 separates the transmitted stream signal into at least one of a multiplexed video information signal, audio information signal, character / graphic information signal, and other data signals, and a decoder corresponding to each signal Output a signal to For example, an audio information signal is output to the audio decoder 105, a video information signal is output to the video decoder 106, and other data signals are output to the control means (CPU) 112 or a decoder corresponding to each data.

  The audio decoder 105 decodes the transmitted audio information signal and outputs it to the speaker 108 as audio.

  The video decoder 106 decodes the transmitted video information signal, converts it into a video signal that can be output on the display screen 109, and outputs it to the display control means 107.

  Similarly, each signal such as data broadcast content, text / figure / still image information, subtitle / text super information, etc. is converted into screen output control information by the control means (CPU) 112 or a decoder corresponding thereto, and the display control means 107. Output to.

  In the display control means 107, based on the transmitted video signal and screen output control information, the display screen 109 such as the display size and display position of the video information signal and other data (for example, characters, graphics, still images, subtitles, character super, etc.) is displayed. The information to be output is stored in units of one virtual display area 500 (hereinafter referred to as “window”). In addition, information on the window stack order indicating the overlap of the windows 500 is also held. (The storage unit 113 may realize the holding) Based on the information held in each window, the transmitted video signal is stored in the video plane buffer, and in the image plane buffer based on the transmitted screen output control information. Each is output in a format to be output to the screen display, and further, the video plane buffer and the image plane buffer are combined and output to the display screen 109 (for example, VRAM). FIG. 3 is an example in which three different pieces of information (for example, video signals, characters, and still images) are simultaneously displayed on three windows on the display screen 109.

  The display configuration management unit 110 manages each window information held by the display control unit 107, receives a processing request regarding the window from the application via the control (CPU) 112, and based on this request, the window configuration window The display control means 107 is instructed to generate and delete data and to change window information such as the display position, display size, and window stack order.

  In addition, the display configuration management unit 110 has a function of giving discrimination information for discriminating a window for displaying a broadcast video to the window. As a method for giving the discrimination information, for example, a broadcast video display discrimination flag is provided as one of the window information, and when the value of the broadcast video display discrimination flag is OFF (for example, an integer value 0), a window for displaying other than the broadcast video is used. If the value of the broadcast video display determination flag is ON (for example, integer value 1), it is recognized as a flag for displaying the broadcast video. Note that this assumes information used to determine whether or not the window is a broadcast video display, and it is also determined using an ID or character string variable indicating the contents displayed in each window. Even if it uses the method to do, it is set as the same provision method.

  Further, the display configuration management unit 110 compares the display position, display size, and stack order of each window information at a predetermined timing, and the window of the broadcast video is displayed due to other windows being displayed on the front. A browsing impossible detection function 111 for determining whether there is a phenomenon in which at least a part of the display is missing is provided. As a result of the determination, the browsing disabled processing means 114 is notified that a phenomenon in which at least a part of the window for displaying the broadcast video is missing is detected.

  The browsing impossible processing means 114 executes processing corresponding to the notified contents. For example, if the notification indicates that a phenomenon in which at least a part of a window for displaying broadcast video is missing has occurred, the recording unit 115 starts recording the broadcast being received.

  With the configuration as described above, the playback processing apparatus 100 can detect a phenomenon in which part or all of the broadcast video is not displayed, and can execute a corresponding process in response to the detection. From this, it is detected that a part or all of the broadcast video is not visible when another window is displayed in front of the broadcast video despite the normal reception of the television broadcast. By starting recording at the same timing, it becomes possible to browse later a portion that the viewer missed the broadcast video or data broadcast or a portion that was hidden by another window and could not be seen.

  Hereinafter, a specific processing procedure will be described with reference to FIG. FIG. 2 is a flowchart showing processing related to the present invention among the processing performed by the display configuration management means 110 in the playback processing apparatus. The display configuration management unit 110 starts processing periodically or triggered by notification from the control unit (CPU) 112, the display control unit 107, or the like.

  First, the display configuration management unit 110 receives a window generation process, a window deletion process, or a display position of each window, a display size, from a host application using the display configuration management unit 110 via a control unit (CPU) 112. Upon receiving a request notification regarding processing for changing attribute values such as stacking order and visualization flag, it is confirmed whether or not there is a change in the window configuration (S2001). Here, a case where a change in the attribute value occurs by executing the request notification (the display configuration management unit 110 executes the window process) or a case where a change in the attribute value has already occurred (display configuration management unit) The means other than 110 executes the window processing). If there is a change in the attribute value, it is determined that there is a change in the window configuration (Yes in S2001), and the process in step S2002 is continued. On the other hand, if there is no change in the attribute value, there is no change in the window configuration (No in S2001), and the process ends.

  Next, it is confirmed whether the broadcast display processing function is being executed (S2002). If the broadcast display processing function is being executed (Yes in S2002), it is necessary to check whether the entire broadcast video window (display area) has been output to the display screen 109, and thus the processing in step S2003 is continued. If the broadcast display processing function is not being executed (No in S2002), the broadcast video is not output to the display screen 109, and the process is terminated.

  Next, it is confirmed whether a window for outputting broadcast video is generated (S2003). If the window for outputting the broadcast video has not been generated (No in S2003), the broadcast video is not output to the display screen 109 even though the broadcast video processing function is being executed. Transition to processing. If a window for outputting a broadcast video has been generated (Yes in S2003), step S2004 is continued.

  Next, a process of determining whether or not the entire window for outputting the broadcast video is output to the display screen 109 is executed (S2004). Detailed processing of this processing will be described later.

  Next, as a result of the process in step S2004, the process to be executed branches depending on whether or not the entire window for outputting the broadcast video is output to the display screen 109 (S2005).

  When it is determined that the entire window of the broadcast video output window is not output on the display screen 109 (No in S2005), the browsing disabled flag is checked (S2009). If OFF, browsing to the browsing disabled processing means 114 is disabled. And the cause thereof are notified (S2010), and the browsing impossible flag is set to ON (S2011). The browsing impossible flag is a flag indicating that the browsing disabled time processing unit 114 has already been notified in a state where the entire window for outputting the broadcast video is not output on the display screen 109. It is provided with the intention of preventing redundant notifications. The browsing impossible flag does not specify the details of the implementation as long as the above intention is satisfied. You may provide as an attribute value of the window which outputs a broadcast image | video, and you may provide as a global value. When the browsing impossible flag is ON, since the browsing impossible processing means 114 has already been notified, the subsequent processing is skipped.

  If it is found that the entire window for outputting the broadcast video is output to the display screen 109 (Yes in S2005), the viewing impossible flag is checked (S2006). Is displayed to the browsing impossible time processing means 114 (S2007), and the browsing impossible flag is set to OFF (S2008). When the browsing impossible flag is OFF, since the browsing impossible processing means 114 has already been notified, the subsequent processing is skipped.

  Upon receiving the notification by the processing in steps S2010 and S2007, the browsing impossible processing means 114 executes processing corresponding to the content of the notification (S2101). For example, when a part or all of the window for outputting the broadcast video is not output on the display screen 109, the recording unit 115 is notified of a request for recording the broadcast content of the selected channel. Receiving the notification of the recording request, the recording unit 115 starts recording the broadcast contents of the selected channel (S2201).

  With the above processing flow, it is possible to detect a case where part or all of the display area of the broadcast video is not visible, and to perform corresponding processing such as starting recording of the broadcast program being browsed.

  Note that the order of the processes in steps S2001 to S2003 may be reversed as long as it satisfies the determination process for executing step S2004. In order to realize equivalent processing, if the start of the flowchart of FIG. 2 is an implementation that is called by a notification from the control device 112, the display control means 107, and the like due to the occurrence of a window configuration change, Since it is obvious that a change in the window configuration has already occurred, an implementation that does not require the processing in step S2001 is also assumed.

  In the process of step S2004, as a method for detecting whether the entire window for outputting the broadcast video is output on the display screen 109, for example, there is a detection method described below. In the following description, the width of the display screen is assumed assuming a two-dimensional matrix in pixel units with the upper left corner of the display screen as the origin (0, 0), the horizontal direction of the display screen as the X axis, and the vertical direction as the Y axis. Is expressed as W and the vertical width as H. The coordinates of the upper left corner of the window for outputting the broadcast video are expressed as (PX, PY), the horizontal width as PW, and the vertical width as PH (FIG. 5).

  (Detection method 1) When PW and PH are not larger than a certain size necessary for viewing broadcast video. For example, in a window with PW = 2 and PH = 2, when the viewer cannot sufficiently recognize it as a broadcast video (FIG. 5), it is detected that browsing is impossible.

  (Detection Method 2) A case where PX <0 or (PX + PW)> W, PY <0 or (PY + PH)> H, and at least a part of the window for outputting the broadcast video is not displayed beyond the display screen (FIG. 4). Detects that browsing is not possible.

  (Detection Method 3) The display control means 107 changes the window depending on the attribute value of the window that outputs the broadcast video (for example, the attribute value indicating the unmapped state in the X Window System (registered trademark) environment or the attribute value indicating that display is impossible). When it is set not to be displayed, it is detected as being unviewable.

  (Detection method 4) When the display rectangle of another window overlaps the entire surface of the window that outputs the broadcast video. When the coordinates of the upper left corner of another window are expressed as (QX, QY), the horizontal width is expressed as QW, and the vertical width is expressed as QH (FIG. 5), overlapping can be determined using the following rectangular area overlapping condition. it can. The rectangular area overlapping condition 1 is when both the expressions QX ≦ PX ≦ (QX + QW) and QY ≦ PY ≦ (QY + QH) are satisfied at the same time. The rectangular area overlapping condition 2 is when both the expressions QX ≦ PX ≦ (QX + QW) and QY ≦ (PY + PH) ≦ (QY + QH) are satisfied at the same time. The rectangular area overlapping condition 3 is when both the expressions QX ≦ (PX + PW) ≦ (QX + QW) and QY ≦ PY ≦ (QY + QH) are satisfied at the same time. The rectangular area overlapping condition 4 is when both the expressions QX ≦ (PX + PW) ≦ (QX + QW) and QY ≦ (PY + PH) ≦ (QY + QH) are satisfied at the same time. However, in any case, PW> 0, PH> 0, QW> 0, QH> 0, and a stacking order in which other windows than the window for outputting broadcast video are output to the front, and the front Other windows displayed in the window are not set so that the display control means does not display the window depending on the attribute value. Further, when a transparent process is performed on a part or all of the overlapping windows and the entire window for outputting the broadcast video is visible, it is not detected that browsing is impossible.

  (Detection method 5) In the case of so-called key color setting in which a specific color is designated and treated as a transparent color, or the image plane and the moving image plane are combined with respect to the coordinates where the specific color is designated, After detecting whether another window overlaps the front of the window that outputs the broadcast video, it is checked whether the key color is used in the overlapping part on the window side that outputs the broadcast video. If the key color is used, it is detected that a part of the broadcast video is invisible.

  (Detection method 6) When a window that displays a broadcast video and other windows are configured using a mask that is not a rectangular area, whether or not the other window overlaps the front of the window that outputs the broadcast video. After the detection, it is determined whether the mask patterns of the overlapping portions of the windows are overlapped in coordinate units. As a result of the determination, if the portion of the mask pattern of another window that is to be displayed overlaps the portion of the window that is to display the mask pattern of the broadcast video, the portion of the broadcast video Is detected to be invisible (FIG. 6).

  (Detection method 7) When a window for outputting broadcast video and another window overlap with each other by translucent processing by alpha processing, it is possible to detect whether or not browsing is possible by providing an alpha value threshold. . For example, when the other window overlaps the front of the window that outputs the broadcast video and the alpha value of the other window exceeds 50%, it is possible to detect that browsing is impossible.

  In addition, in the process of step S2004, other detection rules can be used as long as they detect a phenomenon in which part or all of the window for outputting the broadcast video cannot be displayed. It is not restricted to the method 7.

  Also, in the process of step S2201, it is assumed that a process other than the recording is performed if the process corresponds to the fact that the broadcast video cannot be viewed. For example, the process of recording the date and time when reception is disabled and the channel being received in the recording means 113 (for example, HDD, RAM, external memory device, etc.) 113, or snapping broadcast video at regular intervals rather than recording processing A process of recording a shot as a still image in the storage unit 113 is assumed.

  With the above configuration, when a part or all of the window that displays the broadcast video is not output to the display screen, it is detected as an unviewable event, and the recording process and the unusable event at the timing according to each detection result It is possible to execute processing for the user to miss a part of the broadcast video, such as log accumulation.
