  FIG. 2 is a flow chart for explaining the program missed prevention method of the present invention, FIG. 3 is a schematic operation diagram for explaining the detection and marking position of the CM area of the program video / audio signal in the present invention, and FIG. 4 is the program video / audio in the present invention. FIG. 5 is an operation schematic diagram for explaining the relationship between the position of the CM area of the signal and the reproduction start position of the program video screen including the missed video scene, and FIG. 5 is an example of the video screen displayed on the display device (FIG. 1). (Menu screen) is shown.

  The operation and effect of the embodiment (FIG. 1) of the television apparatus embodying the present invention will be described below with reference to FIG. 2 (flow chart). Now, when a viewer wants to watch a television broadcast program, the operation of the operation unit 5 causes the television device to perform normal television program viewing operations such as power-on and channel selection. The program video screen of the TV broadcast program of the selected specific channel is displayed on the display unit of the display device 1, and the viewer views the program video screen ([Step S01: Start program viewing]).

  When a user is watching such a normal program video screen, he / she can leave the seat because he / she can do something, return to the seat after a certain time, and try to watch a missed video scene First, the menu screen (FIG. 5) is displayed on the display device 1 by the operation of the operation unit 5, the CM return key is selected, and “ON” is selected ([Step: S02]). When the CM return key is turned ON, “YES” is determined in [Step: S02], and the video / audio signal is digitally processed in the video / audio processing unit 41 of the oversight prevention device and recorded (stored) in the recording medium 42. A program video screen based on the video / audio signal is temporarily displayed on the display unit of the display device 1 ([step: S04]). Here, it is essential to record (store) the video / audio signal in the recording medium 42, but the video displayed on the display device 1 is not necessarily recorded (stored) in the recording medium 42. The program may be displayed directly.

  Here, in the case of “NO” in [Step: S02], a program video screen of a normal television broadcast program is displayed on the display unit of the display device 1 [(Step: S03)]. If the CM return key is turned on in [Step: S02], the miss prevention device 4 detects the presence or absence of CM. As the method, for example, the audio discrimination processing unit 43 discriminates the stereo / monaural audio mode from each audio mode such as stereo / monaural and bilingual of the audio signal in the program video audio signal, and the discriminated stereo / mono The monaural audio mode is output to the microcomputer 45, and the audio information processing device (451) in the microcomputer 45 is switched to the position where the stereo audio mode is changed to the monaural audio mode, as shown in FIG. The position for transition to the audio mode is detected, and the start position data or end position data of the CM area of the program video / audio signal is detected ([step: S05]). Here, in [Step: S05], in the case of “NO” (absence of CM area), the determination in [Step: S05] is continued. The method for detecting the presence / absence of CM in the present embodiment is performed by the above-described method. However, as another detection method, a mute portion of an audio signal (portion without sound) and a black mute portion of video signal (video) It is possible to detect the start position data or the end position data of the CM area even by detecting a portion without a signal).

  Next, in the case of “YES” (existence of CM area) in [Step: S05], as shown in FIG. 3B, in the marking processing unit 452, position data at the start of the CM area or position data at the end of the CM area. Is “marking A, B, C...” (In this case, the position at the end of the CM area), and the position data of the CM area is stored in the memory 44 ([step: S06]). Here, as shown in FIG. 3b, the number of position data in the CM area designated as markings (A, B, C...) Is the time until the viewer watches a program video scene that has been overlooked after errand. Since the position data of many CM areas (CM1, CM2, CM3,...) Needs to be taken into consideration, the marking (A, B, C... It is preferable to store the position data up to a range where the storage capacity of the memory 44 is allowed. Needless to say, the marking (A, B, C...) Position data may be position data at the start of the CM area.

  When watching the program video screen with such processing, when the user leaves the seat with some errand, finishes the errand after a certain time and tries to watch the missed video scene, First, a menu screen is appropriately displayed on the display device 1 by a specific CM return key operation by the operation of the operation unit 5 (not shown, but a specific button operation can be requested after the menu button) ( Alternatively, the ON operation is performed a number of times considering the length of time away from the seat.

  Here, it is determined whether or not the CM return key input is stored in the memory 44 ([step: S07]). In [Step: S07], in the case of “NO” (no CM return key input), the determination in [Step: S05] is continued. In [Step: S07], if “YES” (existence of CM return key input), the CM return key is turned on by the operation unit 5 (FIG. 1) when viewing the program video scene that the viewer missed. The number of operations is counted ([Step: S08]). Next, in [Step: S08], when the number of operations for turning on the CM return key is counted, as shown in FIG. 4, the number of counts (for example, when the CM return key is turned on) is counted (for example, The position data of the CM1 area (the end position of the CM1 area) as the marking A immediately before the “missing video scene start position”, which is returned three times, is read from the memory 44 into the reproduction control unit 453 ([Step S09). ]).

  As a result, the audio / video processing unit 41 is controlled by the output control signal of the playback control unit 453, and the time-shift playback operation (CM return) is made from the end position of the CM1 area as the marking A immediately before the “start position” of the missed video scene. (Step S10)), and a program video screen including a video scene that has been missed immediately after the end of CM1 (marking A) is displayed on the display unit of the display device 1.

  In this embodiment, it has been described that the number of times the CM return key is operated is counted in advance, and the time shift reproduction operation is performed according to the number of times. However, the present invention is not limited to this. That is, every time the CM return key is operated, even if the time shift reproduction operation is performed by returning to the previous CM start position, it belongs to the technical scope of the present invention. This is a design matter that can be easily achieved.

  In addition, by displaying a program video screen including a missed video scene reproduced by the time-shift playback operation and a program video screen of a normal television broadcast program in the PinP display method or the PoutP display method, both videos are displayed. You can also watch the screen at the same time. Finally, when the viewing of the TV broadcast program is finished, the position data of each CM area as the marking recorded in the memory 44 is cleared by an operation such as turning off the power of the operation unit 5, and the miss prevention device 4 is Reset.

  As described above, if the program missed prevention apparatus and method of the present invention are applied to a television apparatus, a television apparatus having the above-described effects can be provided by a simple operation.
