Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, specifically to a fiber optic adapter for a camcorder. Background Technology

[0002] With the continuous development of film and television production technology, camcorders are being used more and more widely on various shooting sites.

[0003] However, traditional signal transmission methods are often limited by the length and quality of cables, failing to meet the demands for long-distance, high-quality signal transmission. Fiber optic communication technology, with its advantages of high bandwidth, low attenuation, and strong anti-interference capabilities, has become an effective solution to this problem. Furthermore, in scenarios requiring live broadcasts, such as sports events, cameras need to be connected to dedicated equipment to transmit video signals via fiber optic cables for real-time broadcasting. Existing equipment typically connects cameras to other devices over long distances using cables, resulting in multiple long-distance transmissions of the video signal, affecting video clarity. Moreover, each device, including the camera, requires its own power supply, leading to chaotic wiring and potential accidental disconnections. Additionally, long-distance guided power transmission results in power loss during transmission, further impacting imaging and video transmission quality.

[0004] Therefore, how to provide a fiber optic adapter for camcorders that overcomes the shortcomings of existing adapters is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] To address this issue, this invention provides a fiber optic adapter for a camcorder to solve the problem of poor video viewing quality caused by long-distance video signal transmission in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The receiver component housing has a hollow internal structure, in which a signal processing module is installed. Several control knobs are installed on the front surface of the receiver component housing.

[0009] An output interface is disposed on the outer surface of the housing of the receiving component;

[0010] The output component housing has an internal installation space, in which a signal transmission module is installed. The output component housing is equipped with a transmission interface and a power interface.

[0011] Fiber optic connectors are respectively installed on the right side of the receiver assembly housing and the front side of the output assembly housing;

[0012] A display screen is mounted on the rear surface of the output component housing and the left surface of the receiver component housing. Heat dissipation grilles are also mounted on the rear surface of the output component housing and the left surface of the receiver component housing.

[0013] The signal processing module and the signal transmission module are connected by a signal.

[0014] In one possible implementation, a V-shaped buckle is screwed onto the rear wall of the receiving component housing, the V-shaped buckle comprising:

[0015] A V-shaped plate is screwed to the rear plate of the receiving component housing at its front end. A sliding groove is formed on the rear surface of the V-shaped plate, and the sliding groove extends vertically to the upper and lower surfaces of the V-shaped plate.

[0016] A limiting groove is provided on the right surface of the V-shaped plate and extends into the interior of the V-shaped plate to communicate with the sliding groove.

[0017] Several slots are provided on the rear surface of the V-shaped plate, and the limiting groove is provided on the periphery of the slots.

[0018] In one possible implementation, a dual-color tally indicator light is provided on the surface of the receiving component housing, and the dual-color tally indicator light is electrically connected to the signal processing module.

[0019] In one possible implementation, a circular hole is formed on the front surface of the output component housing. The circular holes are arranged in pairs and are located on the left and right sides of the power interface. A limit component is inserted into the circular hole, and the limit component includes:

[0020] The plugs are arranged in pairs, with a flexible round rod installed on the rear surface. The flexible round rod is inserted into the round hole, and a socket is opened on the side wall of the plug.

[0021] The stop lever is inserted into the two sockets at both ends.

[0022] In one possible implementation, the output interface includes:

[0023] Several SDI output interfaces are installed on the right surface of the receiving component housing. A network cable interface is provided below the SDI output interfaces, and a USB interface is provided behind the network cable interface.

[0024] Several audio input ports are provided on the front surface of the receiver component housing, and a return signal switching interface is provided to the right of the upper audio input ports.

[0025] In one possible implementation, the transmission interface includes:

[0026] Several SDI input interfaces are disposed on the front surface of the output component housing, and a remote control interface and a network cable interface are disposed on the left side of the SDI input interfaces;

[0027] The video output interfaces are arranged in pairs and are located to the left of the network cable interface. A tally interface is located below the video output interface.

The contact connection shortens the cable between the camera and the output interface, reducing signal loss during transmission and resulting in better video quality. The output interface and transmission interface are connected using the same SMPTE cable as the camera, avoiding the increased cost associated with using dedicated cables. The signal transmission module receives and stores the video signal recorded by the camera, and then transmits the video through the fiber optic connector and transmission interface. Furthermore, a power interface connects to a power source, and electrical energy is transmitted to the output interface via the SMPTE cable. This energy is then processed by the signal processing module, providing power to both the module and the camera. The shorter cable between the camera and the output interface also reduces energy loss during transmission, preventing waste and significantly improving video clarity. This design offers excellent performance in both live broadcasting and recording. Attached Figure Description

[0045] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0046] Please refer to Figures 1-10 The present invention discloses a fiber optic adapter for a camcorder. The present invention consists of nine parts, such as... Figures 1-3 The system includes a receiver housing 1, an output interface 2, an output housing 3, an optical fiber connector 4, a power interface 5, a transmission interface 6, control knobs 7, a display screen 8, and a heat dissipation grille 9. The receiver housing 1 has a hollow structure inside, in which a signal processing module is installed. Several control knobs 7 are installed on the front surface of the receiver housing 1. The output interface 2 is located on the outer surface of the receiver housing 1. The output housing 3 has an installation space inside, in which a signal transmission module is installed. The transmission interface 6 and the power interface 5 are installed on the output housing 3. The optical fiber connector 4 is installed on the right side of the receiver housing 1 and the front side of the output housing 3, respectively. The display screen 8 is installed on the rear surface of the output housing 3 and the left surface of the receiver housing 1. Heat dissipation grilles 9 are also installed on the rear surface of the output housing 3 and the left surface of the receiver housing 1. The signal processing module and the signal transmission module are connected via a signal.

[0047] In use, the rear end of the camera is connected to the V-shaped buckle 10. At this time, the receiver housing 1 and the camera are connected as a whole. Then, using the SMPTE cable used by the camera, the camera is connected to the signal processing module. The signal processing module converts the video signal into an electrical signal or an optical signal. An optical fiber cable is connected via an optical fiber connector 4 to transmit the optical signal to the network, meeting the requirements of live broadcast systems such as sports events, concerts, and live studio program production. The electrical signal is stored as a signal. The signal output terminal of the SDI output interface 21 is connected to the signal input terminal of the SDI input interface 61 using an SMPTE cable, transmitting the electrical signal to the signal transmission module. The transmission module re-encodes the electrical signal, converting it into a storable electrical signal. This storable signal is then connected to a portable hard drive or computer via the video output interface 64, enabling rapid acquisition of recorded video. The recorded video can be quickly uploaded to the cloud using the fiber optic connector 4 on the output component housing 3, facilitating rapid processing of video and live stream signals. Since recording and live streaming are both prolonged operations, and both the signal processing and transmission modules transmit signals via electrical signals, prolonged use can cause the various units within these modules to heat up. Excessive heat buildup necessitates heat dissipation to prevent overheating from affecting the efficiency of each unit. The heat dissipation grille 9 is used for heat dissipation. The power interface 5 on the output component housing 3 is used to connect to an external power source. The power source transmits electrical energy to the signal transmission module. Since electrical energy is also transmitted through electrical signals, the signal transmission module retains some energy for its own operation and outputs the remaining energy through other SDI input interfaces 61. This energy is then transmitted to the signal processing module via an SMPTE cable. The signal processing module retains some energy and transmits the remaining energy to the camera via the SMPTE cable to charge the camera. This energy distribution method reduces the number of cables connecting various units and the camera to the power source, and avoids multiple wires connecting to the power source, which could affect the current and thus power supply efficiency. The system can control the amount of current flowing into the camera to prevent it from burning out. Furthermore, in existing equipment, the distance between the camera, signal processing module, and signal transmission module is relatively large. Using long-distance, split-current transmission leads to significant current loss during transmission, resulting in waste. Regarding the display screen 8, since the receiver housing 1 is connected to the camera, it's impossible to directly view the camera's recording status, and the video signal is transmitted to the signal processing module. The display screen 8 on the receiver housing 1 allows users to check if the camera is recording normally. The display screen 8 on the output housing 3 is used to determine if the signal transmission module is receiving the video signal normally.This helps determine whether the video signal was successfully recorded.

[0048] In a specific embodiment, such as Figure 4 A V-shaped buckle plate 10 is screwed onto the rear wall of the receiver component housing 1. The V-shaped buckle plate 10 includes a limiting groove 101, a slot 102, a sliding groove 103, and a V-shaped plate 104. The front end of the V-shaped plate 104 is screwed onto the rear plate of the receiver component housing 1. A sliding groove 103 is opened on the rear surface of the V-shaped plate 104. The sliding groove 103 extends vertically to the upper and lower surfaces of the V-shaped plate 104. The slot 102 is located on the right surface of the V-shaped plate 104 and extends into the V-shaped plate 104 to communicate with the sliding groove 103. Several limiting grooves 101 are located on the rear surface of the V-shaped plate 104 and are located around the slot 102. The V-shaped buckle 10 adopts a standard V-shaped camera battery interface, which can connect to cinema cameras of brands such as Sony, Canon, and ARRI. The camera is quickly connected to the V-shaped plate 104 by using the slide groove 103. At the same time, several limiting paddles on the rear surface of the camera are set in the limiting groove 101 and the slot 102 to realize the connection between the receiving component housing 1 and the camera.

[0049] In one specific embodiment, a dual-color tally indicator light is provided on the surface of the receiver housing 1, and the dual-color tally indicator light is electrically connected to the signal processing module. The dual-color tally indicator light is used to indicate whether the video signal is being received normally and whether the camera is charging.

[0050] In a specific embodiment, such as Figures 5-6 The output component housing 3 has a round hole 31 on its front surface. The round holes 31 are arranged in pairs and are located on the left and right sides of the power interface 5. A limit component 11 is inserted into the round hole 31. The limit component 11 includes a plug 111 and a stop bar 112. The plug 111 is arranged in pairs. An elastic round bar is installed on the rear surface and is inserted into the round hole 31. The plug 111 has a socket on its side wall. The two ends of the stop bar 112 are respectively inserted into the two sockets. The circular hole 31 is designed to connect the elastic rod. The elastic structure of the silicone layer on the outer surface of the elastic rod connects it to the circular hole 31. The connection method is that the elastic rod is slightly larger than the circular hole 31. Then, taking advantage of the plasticity of the silicone layer, when the elastic rod enters the circular hole 31, the silicone layer presses against the surface of the circular hole 31 to limit the elastic rod. Because the insertion depth of the plug 111 needs to be adjusted according to the size of the power output interface, the stop bar 112 can press against the power output interface to limit the power output interface and prevent it from falling off.

[0051] In a specific embodiment, such as Figure 7The output interface 2 includes an SDI output interface 21, a network cable interface 22, a USB interface 23, an audio input port 24, and a return signal switching interface 25.

A USB interface 23 is provided behind the network cable interface 22. Several audio input ports 24 are provided on the front surface of the receiver component housing 1. A return signal switching interface 25 is provided to the right of the upper audio input port 24. The SDI output interface 21 is used to receive video signals captured by the camera. The SDI output interface 21 can simultaneously receive two 12G-SDI video signals. The network cable interface 22 can be used to connect to the Internet when performing live variety shows. Unlike the transmission of fiber optic signals, network transmission uses electrical signals for propagation. The USB interface 23 can be used to connect to mobile devices such as computers. The audio input port 24 can be used to connect wireless or wired microphones to work with the silent video signals generated by the camera. The return signal switching interface 25 can be used to connect to devices such as earphone monitors, providing real-time audio and video feedback to performers on stage, helping them better grasp the progress of the performance and their own performance status.

The video output interfaces 64 are arranged in pairs, located to the left of the network cable interface 62, and the tally interface 63 is located below the video output interface 64. The SDI input interface 61 is used to receive and transmit video signals. The network cable interface 62 is also used to connect a network cable. The tally interface 63 can be used to provide power to the power unit controlling the dual-color tally indicator in the signal processing module. The video output interface 64 can be used to output video signals. The remote control interface 65 is used to connect to mobile devices such as mobile phones to remotely operate video recording.

[0053] In a specific embodiment, such as Figure 9 A fan 12 is mounted on the bottom of the top surface of the receiving component housing 1, with the left end of the fan 12 attached to the heat dissipation grille 9.
