[0001] The present invention relates to an information processing apparatus that can be controlled from an external device, a system, a control method for an information processing apparatus, and a program. [Background technology]

[0002] In recent years, there is a distribution system that distributes images from multiple fixed cameras while switching them with a switcher. In addition, there is a technology to prevent simultaneous control from multiple remote controls when controlling the change of the camera's shooting angle of view with a remote control. Patent Document 1 describes that exclusive control is performed on operation signals from other interfaces during the period from when an operation signal is received until the operation of the device ends, or until all of a series of operation signals end.

[0003] [Patent Document 1] JP 2018-33006 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned distribution system, when distributing video by switching between videos from multiple fixed cameras, it may be difficult for one user to switch between the videos and change the camera's shooting angle of view, etc. Therefore, it is possible to consider an operation in which a person other than the user in charge of controlling the switcher that switches between the videos from the cameras controls the camera's shooting angle of view, etc., by remote control. The technology described in Patent Document 1 can exclude the control of cameras by multiple remote controls, but does not take into consideration whether the video of the camera to be controlled is being distributed by the switcher. Therefore, if a person other than the switcher remote controls a camera that is currently distributing video due to an error, there is a risk that a video different from the one intended by the switcher will be distributed.

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to prevent unintended operations from occurring when an external device controls a video distribution device. [Means for solving the problem]

[0006] The present invention is an information processing device for distributing video captured by an imaging unit, characterized in that it has an acquisition means for acquiring status information regarding the distribution status of the video, a receiving means for receiving a control instruction from an external device, and a control means for controlling not to perform processing instructed by the receiving means when the status information acquired by the acquisition means is in a predetermined state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] [First embodiment] The video distribution device according to the first embodiment will be described below with reference to FIGS. 1 is a schematic diagram showing the configuration of a video distribution device 100 according to the first embodiment. The video distribution device 100 is an example of an information processing device. The CPU 101 is a central processing unit that controls the entire video distribution device 100 . The ROM 102 is a non-volatile memory such as an EEPROM or a flash memory. The RAM 103 is a volatile memory such as an SRAM or a DRAM. Programs for implementing the functions according to this embodiment and data used when the programs are executed are stored in the ROM 102 etc. These programs and data are appropriately loaded into the RAM 103 via the bus 110 under the control of the CPU 101 and executed by the CPU 101.

[0010] The imaging unit 120 includes a zoom lens 121, a focus lens 122, an aperture 123, and an imaging element 124 configured with an image sensor or the like. The zoom lens 121 is moved along the optical axis by a lens driving unit 125. Similarly, the focus lens 122 is moved along the optical axis by the lens driving unit 125. The aperture 123 is driven and operated by the lens driving unit 125. The imaging element 124 photoelectrically converts light that has passed through the zoom lens 121, the focus lens 122, and the aperture 123 to generate an analog image signal. The generated analog image signal is subjected to amplification processing by sampling processing such as correlated double sampling, and then input to a camera signal processing unit 130.

[0011] The camera signal processing unit 130 converts the analog image signal from the imaging unit 120 into a digital image signal by A / D conversion, and then performs various types of digital image processing. The various types of digital image processing include, for example, offset processing, gamma correction processing, gain processing, RGB interpolation processing, noise reduction processing, contour correction processing, color correction processing, light source type determination processing, etc. The digitally processed video is stored in the RAM 103 via the bus 110. The motor control unit 140 controls the driving of the lens driving unit 125 and the camera platform driving unit 141. The camera platform driving unit 141 is a motor mechanism that rotates the camera platform on which the entire imaging unit 120 is mounted, in the pan direction and the tilt direction.

[0012] The video stored in RAM 103 from camera signal processing unit 130 is output to the outside as an external display signal through external display unit 170, and is also compressed by compression / decompression unit 150 and stored in storage device 160. Note that the external display signal in this embodiment uses an SDI (serial digital interface) signal and an HDMI (High-Definition Multimedia Interface) (registered trademark) signal, but is not limited to these. The video output to the outside through external display unit 170 is provided to an external device (for example, switcher 281 in FIG. 2). The storage device 160 is a storage device such as an HDD (hard disk drive), an SSD (solid state drive), or an eMMC (embedded multimedia card).

[0013] LED 171 is a tally lamp that indicates whether an external device (e.g., switcher 281 in FIG. 2) that receives the video being output externally has selected the video as being distributed or as being on standby. The tally lamp is made up of multiple lamps, and is provided in a position that is easy to see from the subject side, or in a position that is easy to see from an operator (e.g., remote control operator 270 in FIG. 2) that issues control instructions to video distribution device 100. Also, the distribution status, such as video being distributed or on standby, can be distinguished by multiple colors such as red and green. The serial communication unit 180 is an interface for communicating with an external device (for example, the switcher 281 in FIG. 2). When the serial communication unit 180 receives control information for issuing various control instructions to the video distribution device 100, the CPU 101 performs various processes according to the control information. The infrared receiver 181 receives a control command from an infrared remote control (for example, the infrared remote control 271 in FIG. 2) that issues various control instructions to the video distribution device 100. When the infrared receiver 181 receives a control command from the video distribution device 100, the CPU 101 controls the motor control unit 140 in response to the control command to change the imaging direction and zoom ratio, and also performs various operations such as changing the shooting conditions.

[0014] FIG. 2 shows an example of the overall configuration of a distribution system including the video distribution device 100 of this embodiment. This distribution system includes a studio 200 where video is shot, and a sub-control room 210 in which a switcher 281 is installed that is connected to PTZ (pan-tilt-zoom) cameras 220-222 fixed at predetermined positions in the studio 200. The PTZ cameras 220-222 each have a built-in video distribution device 100 of Fig. 1. Note that in this embodiment, videos from three PTZ cameras 220-222 are provided to the switcher 281, but the number of PTZ cameras that capture the videos provided to the switcher 281 is not limited to three.

[0015] Monitors 230-232 for video confirmation are installed near the PTZ cameras 220-222, respectively, and are connected by HDMI cables 240-242. Video images output from the external display units 170 of the PTZ cameras 220-222 are displayed on the monitors 230-232 for video confirmation via the HDMI cables 240-242. The PTZ cameras 220-222 are also connected to a switcher 281 via SDI cables 250-252. Videos output from the external display units 170 of the PTZ cameras 220-222 are sent to the switcher 281 via the SDI cables 250-252. The switcher 281 receives videos from the PTZ cameras 220-222, switches the received videos as appropriate, and outputs them to downstream live streaming equipment or a recording device (not shown). Furthermore, the PTZ cameras 220-222 and the switcher 281 are connected in a daisy chain manner by serial cables 260-263. The serial communication units 180 of the PTZ cameras 220-222 communicate control information and the like via the serial cables 260-263 under the control of the CPU 101.

[0016] A remote control operator 270 operates an infrared remote control 271 at a position where he can check the video monitors 230-232 in the studio 200. The remote control operator 270 operates the infrared remote control 271 to transmit control commands for controlling the angle of view, shooting conditions, and the like to the PTZ cameras 220-222. The infrared receivers 181 of the PTZ cameras 220-222 receive the control commands from the infrared remote control 271. The infrared remote control 271 is an example of an external device.

[0017] In the sub-control room 210, there is a switcher operator 280 who operates a switcher 281 while watching a multi-screen monitor 282. The multi-screen monitor 282 is connected to the switcher 281 via an SDI cable 283. The multi-screen monitor 282 displays images from the PTZ cameras 220 to 222, and it is possible to know which of the PTZ cameras 220 to 222 images is being used for distribution or recording. The switcher operator 280 operates the PTZ cameras 220 to 222 to select a PTZ camera for video distribution or recording, or a PTZ camera for preview (also called standby). When a PTZ camera is selected, the switcher 281 transmits a tally lamp control command to the selected PTZ camera via the serial cables 260 to 263. Specifically, it transmits a red tally lamp turn-on command to the PTZ camera for video distribution or recording, a green tally lamp turn-on command to the PTZ camera for preview, and a tally lamp off command to the PTZ camera removed from the selection. When the serial communication unit 180 of the PTZ cameras 220-222 receives a tally lamp control command from the switcher 281, the CPU 101 controls the turning on and off of the LED (tally lamp) 171 in accordance with the received tally lamp control command. In other words, the on / off lighting state of the tally lamp reflects whether video is being distributed or not. The on / off lighting state of the tally lamp is an example of status information related to the distribution status.

[0018] Fig. 3 is a flowchart showing the flow of control of video distribution device 100. The processing of the flowchart shown in Fig. 3 is realized by CPU 101 expanding a program stored in ROM 102 into RAM 103 and executing it. The processing of the flowchart shown in Fig. 3 starts when the distribution system is installed as shown in Fig. 2. In this flowchart, CPU 101 functions as a receiving means, an acquiring means, and a control means. In step S300, CPU 101 waits until a control command transmitted from infrared remote control 271 is received by infrared receiving unit 181. If CPU 101 determines that a control command has been received from infrared remote control 271, the process proceeds to step S310. In step S310, CPU 101 acquires the lighting state of LED (tally lamp) 171 and determines whether it is on or not. If CPU 101 determines that the lighting state of LED (tally lamp) 171 is off, the process proceeds to step S320 to process a control command from infrared remote control 271. In step S320, CPU 101 performs processing in response to the control command from infrared remote control 271. Thereafter, the processing returns to step S300.

[0019] On the other hand, if the CPU 101 determines in step S310 that the LED (tally lamp) 171 is in an ON state (predetermined state), the process proceeds to step S330. In step S330, CPU 101 invalidates the control command from infrared remote control 271. That is, CPU 101 controls so as not to process the control command. After that, in step S340, CPU 101 blinks LED (tally lamp) 171 to warn of the invalidation. In this case, a lamp provided in a position that is easily visible from remote control operator 270 is blinked, and a lamp provided in a position that is easily visible from the subject side is kept lit. Note that in this embodiment, the invalidation is warned by blinking LED (tally lamp) 171, but the warning may be issued in other ways, such as blinking monitors 230 to 232 for video confirmation. Then, the process returns to step S300.

[0020] In the above flow chart, when a control command is received in step S300, it is determined whether the illumination state of the LED (tally lamp) 171 is on or off, but this is not limited to the above method. As another method, when the LED (tally lamp) 171 changes from an off state to an on state, the CPU 101 may be controlled not to accept a control command from the infrared remote control 271. In this case, in response to the change of the LED (tally lamp) 171 from an on state to an off state, the CPU 101 enables acceptance of a control command from the infrared remote control 271.

[0021] According to the first embodiment as described above, when the remote control operator 270 controls the PTZ cameras 220 to 222, such as by changing the angle of view, using the infrared remote control 271, if video is being distributed by the switcher 281, the control from the infrared remote control 271 can be disabled. This prevents video unintended by the switcher operator 280 from being distributed due to an erroneous operation by the remote control operator 270.

[0022] [Second embodiment] The video distribution device of the second embodiment will be described below with reference to Figures 4 to 10. In the first embodiment, the video distribution device 100 is controlled by infrared communication. The second embodiment differs from the first embodiment in that the video distribution device 100 is controlled by wireless LAN communication instead of infrared communication. FIG. 4 is a schematic diagram showing the configuration of a video distribution device 400 according to the second embodiment. Fig. 4 corresponds to Fig. 1 in the first embodiment, so only the differences between Fig. 1 and Fig. 4 will be described, and other descriptions will be omitted. In the video distribution device 400 in Fig. 4, the serial communication unit 180 and the infrared receiving unit 181 in Fig. 1 are replaced with an IP (Internet Protocol) communication unit 410. The IP communication unit 410 is an interface for connecting to the network 420 via a wireless or wired LAN and communicating with an external device. The video distribution device 100 communicates control commands and the like with the switcher 281 or a remote control (for example, the WiFi remote control 571 in FIG. 5) using the IP communication unit 410. The video distribution device 100 also transmits images captured by the imaging unit 120 and stored in the RAM 103 to the switcher 281 or the remote control (the WiFi remote control 571) using the IP communication unit 410. Note that the video distribution device 400 in FIG. 4 can transmit images to the outside using the IP communication unit 410, so the external display unit 170 in FIG. 1 does not need to be provided.

[0023] FIG. 5 shows an example of the overall configuration of a distribution system including a video distribution device 400 according to this embodiment. Fig. 5 corresponds to Fig. 2 in the first embodiment, so only the differences between Fig. 2 and Fig. 5 will be described, and other descriptions will be omitted. Each of PTZ cameras 520 to 522 in Fig. 5 has the video distribution device 400 in Fig. 4 built in. A WiFi router 590 is installed in the studio 200 in Fig. 5. The WiFi router 590 is a wireless LAN access point, and is connected to the network 420. The WiFi router 590 is provided with a plurality of LAN ports. The WiFi router 590 and the PTZ cameras 520 to 522 are connected to each other by LAN cables 550 to 552. The WiFi router 590 and the switcher 281 are also connected to each other by a LAN cable 553. The IP communication units 410 of the PTZ cameras 520 to 522 receive control information from the switcher 281 via the WiFi router 590 under the control of the CPU 101.

[0024] The remote control operator 270 operates a WiFi remote control 571 instead of the infrared remote control 271 in FIG. 2. The WiFi remote control 571 can communicate with the PTZ cameras 520-522 via a WiFi router 590 by wireless LAN such as WiFi. Images of the PTZ cameras 520-522 are displayed on the WiFi remote control 571, and the remote control operator 270 can operate the PTZ cameras 520-522 while viewing the images of the PTZ cameras 520-522 to which the remote control operator 270 gives control instructions. By operation by the remote control operator 270, the WiFi remote control 571 transmits control commands to the PTZ cameras 520-522 via the WiFi router 590 to adjust the angle of view, control the shooting conditions, and the like. The IP communication units 410 of the PTZ cameras 520-522 receive the control commands from the WiFi remote control 571 via the WiFi router 590. The WiFi remote control 571 is an example of an external device.

[0025] 2, and the monitors 230-232 for checking images are not required. Images displayed on the monitors 230-232 of the PTZ cameras 520-522 are transmitted from the PTZ cameras 520-522 to the WiFi remote control 571 via the WiFi router 590, and are displayed on the WiFi remote control 571. Images are also transmitted from the PTZ cameras 520-522 to the switcher 281 via the WiFi router 590, and are displayed on the multi-screen monitor 282.

[0026] FIG. 6 is a schematic diagram showing the configuration of the WiFi remote control 571. The CPU 601 is a central processing unit and controls the entire WiFi remote control 571. The ROM 602 is a non-volatile memory such as an EEPROM or a flash memory. The RAM 603 is a volatile memory such as an SRAM or a DRAM. Programs for implementing the functions according to this embodiment and data used when the programs are executed are stored in the ROM 602 etc. These programs and data are appropriately loaded into the RAM 603 via the bus 610 under the control of the CPU 601 and executed by the CPU 601.

[0027] The touch panel 604 is used for selecting the PTZ cameras 520-522 and for displaying images of the PTZ cameras 520-522. The operation unit 605 performs an operation to change the imaging direction and zoom ratio of the PTZ cameras 520-522 selected on the touch panel 604. When the operation unit 605 is operated, the CPU 601 generates a control command corresponding to the operation content and transmits the control command via the wireless communication unit 606 to the selected PTZ cameras 520-522. The wireless communication unit 606 is an interface for communicating with external devices via a wireless LAN through a WiFi router 590. The WiFi remote control 571 communicates control commands and the like with the PTZ cameras 520-522 using the wireless communication unit 606. The WiFi remote control 571 also receives images from the PTZ cameras 520-522 using the wireless communication unit 606 and displays them on the touch panel 604.

[0028] FIG. 7 is a diagram showing an example of the appearance of the WiFi remote control 571. The touch panel 604 of the WiFi remote control 571 is provided with a camera selection area 710, a tally display area 720, and a camera video display area 730. The camera selection area 710 is an area for selecting the PTZ cameras 520 to 522 for which a control instruction is to be given. The tally display area 720 is an area for displaying the lighting state of the tally lamps of the selected PTZ cameras 520 to 522. The camera video display area 730 is an area for displaying the video output from the selected PTZ cameras 520 to 522. When a PTZ camera is selected in the pull-down menu of the camera selection area 710, the WiFi remote control 571 transmits a camera selection command to the corresponding PTZ camera via the WiFi router 590. The PTZ camera that receives the camera selection command transmits the captured video and the lighting state of the tally lamp to the WiFi remote control 571 via the WiFi router 590. When the WiFi remote control 571 receives these, it displays them in the tally display area 720 and the camera video display area 730. The WiFi remote control 571 may receive the distribution status of the selected PTZ camera from the switcher 281 via the WiFi router 590 and display the received distribution status in the tally display area 720.

[0029] Furthermore, the operation unit 605 of the WiFi remote control 571 includes a direction instruction area 740 for changing the imaging direction and a zoom ratio instruction area 750 for changing the zoom ratio. When the direction instruction area 740 or the zoom ratio instruction area 750 is operated, the WiFi remote control 571 transmits a control command corresponding to the operation content to the PTZ cameras 520 to 522 selected in the camera selection area 710 via the WiFi router 590.

[0030] Fig. 8 is a flowchart showing the flow of control of the video distribution device 100 and the WiFi remote control 571. Comparing the flowchart shown in Fig. 8 with the flowchart in Fig. 3, the difference is that step S300 is replaced with step S800, and step S340 is replaced with step S810. Therefore, steps S800 and S810 will be explained, and other explanations will be omitted. In this flowchart, the CPU 101 of the video distribution device 100 functions as a receiving means, an acquiring means, and a control means.

[0031] In step S800, CPU 101 of video distribution device 100 waits until a control command from WiFi remote control 571 is received by IP communication unit 410. Unlike the first embodiment, in this embodiment, both the control command from WiFi remote control 571 and the control command from switcher 281 are received via IP communication unit 410. Therefore, in order to identify the source of the control command, a data table such as that shown in FIG. 9 is stored in ROM 102 of video distribution device 100. 9 is a data table showing the correspondence between the types of devices capable of controlling the video delivery device 100 and IP addresses. In this data table, the IP address of the switcher 281 and the IP address of the WiFi remote control 571 are stored. The CPU 101 of the video delivery device 100 determines whether the control command is from the WiFi remote control 571 or the switcher 281 based on the IP address of the control command transmission source. When the WiFi remote control 571 transmits a control command corresponding to the operation content of the operation unit 605 to the video delivery device 100 and the CPU 101 of the video delivery device 100 determines that the control command has been received from the WiFi remote control 571, the process proceeds to step S310. Note that when the CPU 101 of the video delivery device 100 determines that the control command has been received from the switcher 281, the process may proceed to step S320 regardless of the lighting state of the LED (tally lamp) 171, assuming that the control command is an intentional control instruction from the switcher operator 280.

[0032] In step S810, CPU 101 of video distribution device 100 transmits a response message indicating invalidation to WiFi remote control 571 to notify that the control command from WiFi remote control 571 has been invalidated in step S330. Upon receiving the response message from video distribution device 100, CPU 601 of WiFi remote control 571 displays it on touch panel 604. 10 is a diagram showing an example of the display of WiFi remote control 571 that has received a response message indicating invalidation. As shown in FIG. 10, a message display 1000 saying “No operation possible due to distribution” is superimposed on camera video display area 730.

[0033] According to the second embodiment as described above, when the remote control operator 270 controls the PTZ cameras 520 to 522, such as by changing the angle of view, using the WiFi remote control 571, if video is being distributed by the switcher 281, the control from the WiFi remote control 571 can be disabled. This prevents video unintended by the switcher operator 280 from being distributed due to an erroneous operation by the remote control operator 270.

[0034] Although the present invention has been described above with reference to the embodiments, the above embodiments are merely illustrative of the specific examples of the present invention, and the technical scope of the present invention should not be interpreted as being limited by these embodiments. In other words, the present invention can be embodied in various forms without departing from its technical concept or main features.

[0035] (Other embodiments) The present invention can also be realized by a process in which a program for implementing one or more of the functions of the above-described embodiments is supplied to a system or device via a network or a storage medium, and one or more processors in a computer of the system or device read and execute the program. The present invention can also be realized by a circuit (e.g., ASIC) that implements one or more of the functions. [Explanation of symbols]
