  FIG. 7 is a flowchart for explaining the operation in the video display apparatus according to the embodiment when a set user is not detected during program viewing.

  Step S100 is a start step here. Then, it progresses to step S101.

  Step S101 is a step in which, for example, the user (Mr. A) operates the remote controller 21 or the like to turn on the main power supply of the video display device 1A. Then, it progresses to step S102.

  Step S102 is a step in which, for example, a broadcast station that has received the previous broadcast is selected, a broadcast broadcast by this broadcast station is received, and displayed on the display screen 8. Then, it progresses to step S103.

  Step S103 is a step of detecting whether the user (for example, Mr. A here) is preset and stored in the flash memory 15 or the server 27 of the video display device 1A as described above. When it is detected that the user (for example, Mr. A) is set in advance, the process proceeds to step S104 (Yes). When it is detected that the user (for example, Mr. A) is not set in advance, the process returns to step S102 and the above process is repeated (No).

  Step S104 is, for example, a step of imaging the vicinity of the video display device 1A or the like using the imaging unit 30A. Then, it progresses to step S105.

  Step S105 is, for example, a step of determining whether the set user (for example, Mr. A) has been detected in the captured image. If it is determined that the set user (for example, Mr. A) has been detected in the captured image, the process proceeds to step S106 (Yes). When it is determined that the set user (for example, Mr. A) is not detected in the captured image, the process returns to step S102 and the above process is repeated (No).

  Step S106 is, for example, a step of determining whether the user (Mr. A) set in advance and detected as described above is no longer in the imaging range of the imaging unit 30A and is no longer detected.

  If the detected setting user (Mr. A) is no longer detected by the imaging unit 30A, the process proceeds to step S107 (Yes). When the detected setting user (Mr. A) is detected by the imaging unit 30A, the processing here is repeated (No).

  Step S107 is performed when, for example, the user (Mr. A) detected as described above is out of the imaging range of the imaging unit 30A (eg, out of the room A) and is no longer detected. The broadcast program reception information (for example, EPG information) that is displayed and output is associated with the user (Mr. A), for example, a device (video display device 1B) or server 27 that is system-set as shown in FIG. And the like. Then, it progresses to step S108.

  Step S200 is a start step here. Then, it progresses to step S201.

  Step S201 is a step in which the video display device 1B detects the setting user (Mr. A) by imaging the vicinity (for example, the front) of the video display device 1B with the imaging unit 30B. Then, it progresses to step S202.

  Step S202 is a step of determining whether the setting user (Mr. A) has been detected. If the setting user (Mr. A) uses the imaging unit 30B of the video display device 1B and determines that it has been detected, the process proceeds to step S203 (Yes). When the setting user (Mr. A) uses the imaging unit 30B of the video display device 1B and does not determine that it has been detected, the setting user returns to step S201 and repeats the above processing (No).

  Step S203 is a step of turning on the main power supply of the video display device 1B in response to the detection of the setting user (Mr. A), for example. Then, it progresses to step S204.

  Step S204 is a step of acquiring the reception information of the setting user (Mr. A) stored in the flash memory 15B and the server 27.

  As described above, this received information is associated with the user (Mr. A) when the setting user (Mr. A) disappears from the imaging range of the imaging unit 30A and is no longer detected in the video display device 1A. Viewing the program that the user (Mr. A) was watching on the source device (for example, the video display device 1A) transmitted to and stored in the system-set device (video display device 1B), the server 27, etc. Information.

  Then, it progresses to step S205.

  In step S205, a broadcast station is selected using the acquired reception information, and a broadcast (broadcast program) that the user (Mr. A) was watching on the source device (for example, the video display device 1A) is received. This is the step of display output on the display screen 8. Then, it progresses to step S206.

  Step S206 is a step for discriminating whether the user setting of this system has been made in advance as described above. If it is determined that the user setting of this system has been made, the process proceeds to step S207 (Yes). If it is determined that the user setting of this system has not been made, the process proceeds to step S205 and the above process is repeated (No).

  Step S207 is a step of imaging the vicinity (for example, the front) of the video display device 1B with the imaging unit 30B, as described above. Then, it progresses to step S208.

  Step S208 is a step of determining whether or not the setting user (Mr. A) has been detected in the imaging by the imaging unit 30B. When it is determined that the setting user (Mr. A) has been detected, the process proceeds to step S209 (Yes). If it is not determined that the setting user (Mr. A) has been detected, the process proceeds to step S205, and the above process is repeated (No).

  Step S209 is, for example, a step of determining whether the user (Mr. A) set in advance and detected as described above is no longer in the imaging range of the imaging unit 30B and is no longer detected.

  If the detected setting user (Mr. A) is no longer detected by the imaging unit 30B, the process proceeds to step S210 (Yes). When the detected setting user (Mr. A) is detected by the imaging unit 30B, the processing here is repeated (No).

  Step S210 is performed when, for example, the user (Mr. A) detected as described above is out of the imaging range of the imaging unit 30B (for example, out of the room B) and is no longer detected. This is a step of transmitting reception information (for example, EPG information) of the broadcast program being displayed and output to the device (video display device 1A), the server 27, etc. set in the system in association with the user (Mr. A). .

  Then, it progresses to step S211.

  In step S211, for example, when it is determined that the user (Mr. A) detected as described above is no longer in the imaging range of the imaging unit 30B and is no longer detected, video display is performed based on this. This is a step of turning off the main power supply of the apparatus 1B.

  At this time, in this embodiment, in the same manner as described above, when the setting user (Mr. A) next enters the imaging range of the imaging unit 30B again, the user (Mr. A) can be detected. It is desirable not to turn off the power of the imaging device 30B and the like necessary for detection (imaging) of the image.

  Then, it progresses to step S212.

  Step S212 is an end step, and the process here ends.
