[0028] In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more, for example, multiple processing units means two or more processing units, multiple elements means two or more elements, etc.
[0029] Currently, the design of mainstream video encoding equipment and supporting storage solutions mainly focuses on adapting to relatively stable and controlled indoor or fixed environments (such as computer rooms, offices, and classrooms), and their basic service capabilities have reached maturity. However, facing the increasingly complex, ubiquitous, and heterogeneous application needs of modern times, these solutions exhibit inherent adaptation limitations in both functional dimensions and environmental tolerance.
[0030] To address the aforementioned problems, this application proposes an embodiment of a video encoding device, please refer to... Figure 1 , Figure 1 This is one of the structural block diagrams of the video encoding device provided in the embodiments of this application.
[0031] In this embodiment, the video encoding device includes: an interface unit 10, an optical-to-electrical unit 20, a distribution unit 30, and a video processing unit 40. The interface unit 10 includes a first HDMI interface 11 and a spare interface 12.
[0032] It should be noted that the first HDMI interface 11 is connected to the input end of the optical-to-electrical unit 20; the first output end of the optical-to-electrical unit 20 is connected to the input end of the distribution unit 30; the first output end of the distribution unit 30 is connected to the spare interface; and the second output end of the distribution unit 30 is connected to the first input end of the video processing unit 40.
[0033] It should be noted that the first HDMI interface 11 is used to connect an external video capture device to receive HDMI optical signals and output them to the optical-to-electrical unit 20. The external video capture device is the source of the device connected to the first HDMI interface 11. There are many types of external video capture devices, such as professional cameras that can capture high-quality video footage in various shooting scenarios; and surveillance cameras with video capture capabilities that can acquire video information of the monitored area in real time. The video signals generated by these devices are the basic data source for subsequent processing.
[0034] As is understandable, High-Definition Multimedia Interface (HDMI) is a digital video / audio interface technology. The emphasis here is on optical signals, which offer numerous advantages over traditional electrical signal transmission. It supports longer transmission distances with minimal signal attenuation over long distances, ensuring high-quality video signals. Furthermore, optical signals have strong anti-interference capabilities, effectively preventing external electromagnetic interference from affecting the video signal, resulting in clearer, more stable video with higher color fidelity.
[0035] Understandably, the first HDMI interface 11 is a signal input capable of receiving HDMI optical signals output from external video capture devices. After receiving the HDMI optical signal, the first HDMI interface 11 transmits the signal to the optical-to-electrical converter 20. This step is a crucial link in the entire video signal processing flow, acting as a bridge for signal transmission and ensuring that the video signal can smoothly enter subsequent processing stages.
[0036] It should be noted that the optical-to-electrical unit 20 is used to convert HDMI optical signals into HDMI electrical signals and transmit them to the distribution unit 30.
[0037] Understandably, the core function of the optical-to-electrical unit 20 is to convert HDMI optical signals to HDMI electrical signals. Electrical signals are a common signal type used inside electronic devices, and most video processing chips and circuits operate based on electrical signals. Compared to optical signals, electrical signals are easier to transmit and process inside devices, and can achieve good compatibility and interaction with various electronic components and circuits.
[0038] Understandably, this process involves complex photoelectric conversion technology, typically requiring key components such as photoelectric converters. Inside the photoelectric converter is a photodetector sensitive to light signals. When an HDMI light signal shines on the photodetector, the detector generates a corresponding electrical signal based on the intensity and characteristics of the light signal, thus completing the conversion from light to electricity. For example, when changes in the intensity of the light signal represent the brightness information of different pixels in a video image, the resulting electrical signal can accurately reflect these brightness changes, ensuring the complete transmission of video information.
[0039] It should be noted that the distribution unit 30 is used to transmit HDMI electrical signals to the video processing unit 40 and the backup interface 12 respectively. The backup interface 12 is used to connect external devices to output HDMI electrical signals. The video processing unit 40 is used to encode the HDMI electrical signals into a network video stream.
[0040] Understandably, the video processing unit 40 is the core module in the device that performs in-depth processing of HDMI electrical signals. It possesses powerful video encoding, decoding, and format conversion functions, enabling it to optimize and adjust received HDMI electrical signals to meet diverse application needs. For example, it can encode high-definition video signals into low-bitrate formats suitable for network transmission, or convert video signals of different standards into a unified format for normal playback on various display devices.
[0041] Understandably, the backup interface 12 serves as a redundancy design for the device, providing an additional path for video signal transmission. Under normal circumstances, it may be idle, but when the first HDMI interface 11 malfunctions, is damaged, or requires maintenance, the optical-to-electrical unit 20 can switch to the backup interface 12 to ensure continued video signal transmission, thus improving the device's reliability and stability.
[0042] It is understandable that the backup interface 12 can also be used as a direct output port for HDMI electrical signals. The distribution unit 30 can transmit processed or unprocessed HDMI electrical signals to the backup interface 12. Since HDMI signals have unified standards and specifications, as long as the signal received by the backup interface 12 conforms to the HDMI protocol, it can be correctly recognized and parsed by external devices, thereby realizing the output of video and audio. At this time, the backup interface 12 is a second HDMI interface; the second HDMI interface is used to connect an external display device to loop out the HDMI signal to realize the real-time display of video images.
[0043] As can be understood, signal loop output refers to outputting the input signal directly from the output terminal without processing or with minimal processing, forming a signal loop. For example, transmitting the same signal simultaneously to multiple devices, such as a monitor or recording device.
[0044] Understandably, when an HDMI signal needs to be transmitted simultaneously to both the video processing unit 40 and the backup interface 12, the distribution unit will copy the input signal. It will generate two identical signals, one transmitted to the video processing unit 40 and the other to the backup interface 12. During the signal copying process, the distribution unit ensures that the copied signal maintains the same quality as the original signal, without any signal attenuation or distortion.
[0045] Furthermore, to ensure signal stability and reliability during transmission, the distribution unit 30 can enhance and buffer the signal. Signal enhancement increases signal strength, making it better resistant to interference and attenuation during transmission; signal buffering smooths signal transmission, preventing transmission errors caused by sudden signal changes. For example, when transmitting HDMI electrical signals over long distances, the distribution unit increases signal power through its built-in signal enhancement circuit while using a buffer to shape and stabilize the signal, ensuring that the signal reaches the video processing unit 40 and the backup interface 12 accurately.
[0046] Specifically, the composition of the distribution unit and video processing unit is not limited; they only need to implement the aforementioned functions. For example, the distribution unit can be a standalone device (such as an HDMI splitter), a module integrated into the video processing board, or even implemented through software, such as virtualized signal distribution. The protocol is not limited to HDMI; DP, SDI, DVI, and other interfaces can also be selected, depending on the compatibility of the input / output devices. If more output ports are required, cascaded splitters can be used, such as HDMI splitters connected in series, or multi-port devices, such as an 8-port HDMI splitter, can be selected. The video processing unit can choose general-purpose video processing modules such as video processing boards to implement encoding.
[0047] In this embodiment, since the interface unit includes a first HDMI interface (supporting optical signal input) and a backup interface (compatible with electrical signal output), the device can receive HDMI optical signals from external acquisition devices (such as cameras) over long distances and without interference via optical fiber, and can also output standard HDMI electrical signals to back-end devices (such as local displays or video recorders) via the backup interface. This significantly broadens the device's input source compatibility and output connection flexibility, and enhances its applicability in scenarios requiring different signal type conversion or cascading.
[0048] In this embodiment, since the optical-to-electric unit directly receives the HDMI optical signal from the first HDMI interface and converts it into an HDMI electrical signal, the original optical signal can be converted into a standard electrical signal that is easier to process inside the device and at the back end. This solves the cumbersome problem of having to convert the optical signal again at the target device after direct processing or long-distance transmission, and provides a stable and standard signal source for subsequent units.
[0049] In this embodiment, since the distribution unit simultaneously transmits the HDMI electrical signal received from the optical-to-electrical unit to the first input terminal and the backup interface of the video processing unit, the input video electrical signal can be split into two within the device: one path is dedicated to the video processing unit for core encoding processing, and the other path achieves lossless, real-time video signal loop-out through the backup interface. Thus, the key functions of video encoding processing and high-quality original signal local distribution are realized simultaneously within a single device, solving the problem of existing devices having limited functionality and requiring external devices to achieve loop-out, and meeting the basic requirements of security monitoring and other scenarios for simultaneous recording and local real-time preview.
[0050] In this embodiment, since the video processing unit receives the HDMI electrical signal from the distribution unit and encodes it into a network video stream, the high-quality video signal after optical-to-electrical conversion and distribution is efficiently compressed and converted into data suitable for network transmission, thereby realizing the remote playback, storage or live streaming of video, and meeting the core requirements of applications such as distance education, video conferencing, and centralized monitoring for networked transmission of video content.
[0051] Furthermore, based on the above embodiments, this application proposes structural improvements, please refer to... Figure 2 , Figure 2 This is the second structural block diagram of the video encoding device provided in the embodiments of this application.
[0052] In this embodiment, the video encoding device further includes a power conversion unit 50. The interface unit 10 also includes a power supply interface 13; the power supply interface 13 is connected to the input terminal of the power conversion unit 50; the output terminal of the power conversion unit 50 is connected to the second input terminal of the video processing unit 40; the power supply interface 13 is used to connect to mains power and transmit it to the power conversion unit 50; the power conversion unit 50 converts mains power into operating voltage to provide operating voltage for the video processing unit 40.
[0053] Understandably, the power supply interface 13 serves as a bridge connecting the device to external AC power. Its main function is to connect to AC power, which is the 220V (which may vary in different countries and regions) AC power we use in daily life, and transmit the AC power to the subsequent power conversion unit 50, providing the original power input for the entire power conversion process.
[0054] Understandably, the power conversion unit 50 is a core component of the power supply system. It has the ability to convert AC power, transforming the incoming high-voltage AC power into a suitable operating voltage for the various components within the video encoding equipment. Different electronic components and circuits may require different voltage specifications; for example, some chips may require DC voltages such as 3.3V, 5V, or 12V. The power conversion unit 50 can precisely convert the AC power into these appropriate operating voltages according to the equipment's needs, ensuring stable operation of the equipment.
[0055] Understandably, when the device is connected to mains power, the current first enters the device through the power supply interface 13, and then is transmitted to the power conversion unit 50. The power conversion unit 50 performs a series of conversion operations on the input mains power, including step-down, rectification, and filtering, to convert it into a stable operating voltage. Finally, this operating voltage is transmitted through the output terminal to the second input terminal of the video processing unit 40, providing power to the video processing unit 40 so that it can perform video processing work normally.
[0056] In this embodiment, the video encoding device may further include a filtering unit 60. The power supply interface 13 is indirectly connected to the power conversion unit 50 through the filtering unit 60; wherein, the input terminal of the filtering unit 60 is connected to the power supply interface 13; the output terminal of the filtering unit 60 is connected to the input terminal of the power conversion unit 50; the output terminal of the power conversion unit 50 is connected to the second input terminal of the video processing unit 40; the filtering unit 60 is used to filter out interference signals and noise signals in the mains power.
[0057] It is understandable that mains power is affected by various factors during transmission, such as lightning, electrical equipment start-up and shutdown, and power grid failures, resulting in various interferences and noises. If these interferences and noises directly enter the power conversion unit 50, they may affect the accuracy and stability of power conversion, thereby interfering with the normal operation of equipment such as the video processing unit 40, leading to problems such as video encoding errors, snow or stripes in the image. The filtering unit 60 can filter out these harmful interference and noise signals, providing relatively clean AC power to the power conversion unit 50.
[0058] Specifically, an AC EMI filter can be selected, which is constructed using passive components such as inductors and capacitors. These components have high reliability and stability and can operate for extended periods under harsh environmental conditions. Compared to active filters, AC EMI filters do not require an additional power supply, reducing potential points of failure and improving the overall reliability of the equipment.
[0059] In one embodiment, the interface unit includes: a USB interface 14; the USB interface 14 is connected to the third end of the video processing unit 40; the USB interface 14 is used to connect a USB device to realize the storage of network video streams.
[0060] It should be noted that the USB interface 14, as a core component of the interface unit, serves as the bridge for physical connection and data transmission between the video encoding device and external USB devices. The USB interface boasts advantages such as high versatility, fast transmission speed, and hot-swapping support, enabling convenient connection to various types of USB devices, such as external hard drives and USB flash drives. In this embodiment, the main function of the USB interface 14 is to receive network video stream data from the video processing unit 40 and transmit it to the connected USB device for storage; simultaneously, it can also feed back relevant data from the USB device to the video processing unit 40.
[0061] In one embodiment, the video processing unit 40 includes an Ethernet transmission subunit; the Ethernet transmission subunit is used to access a host computer to configure the video processing unit 40 and to enable remote video playback.
[0062] It should be noted that the Ethernet transmission subunit consists of multiple parts to achieve stable and efficient data transmission and communication: the physical layer chip is used to convert digital and analog signals, process low-level operations, and ensure accurate signal transmission; the data link layer chip is used to implement data frame processing, error detection and correction, and flow control, providing reliable transmission services; the Ethernet interface 15 connects to the fourth end of the video processing unit 40 and can be set in the interface unit 10, providing physical interfaces such as RJ-45 and fiber optic interfaces to help the video processing unit 40 access network communication; the microcontroller or processor is used as the core control component to manage and schedule the operation of the subunit and ensure its stable operation.
[0063] Understandably, the host computer is typically a computer or server running specialized configuration software. Once the Ethernet transmission subunit of the video processing unit 40 is connected to the network, the host computer can establish a communication connection with the video processing unit 40 via a network protocol (such as TCP / IP). The configuration software sends configuration commands to the video processing unit 40, which contain setting information for various parameters, such as video encoding format, resolution, frame rate, and network transmission parameters. Upon receiving these commands, the microcontroller or processor in the Ethernet transmission subunit parses and processes them, and sets and adjusts the relevant parameters of the video processing unit 40 according to the command content.
[0064] In this embodiment, a filtering and power conversion unit, a USB interface, and an Ethernet transmission subunit are added to the first embodiment, bringing significant benefits. The filtering unit purifies the signal, enhances anti-interference capabilities, reduces video distortion, and ensures stable signal reception by the system; the power conversion unit adapts to diverse power supply requirements, providing protection and stable power supply to ensure normal system operation; the USB interface expands storage and facilitates convenient data exchange; the Ethernet transmission subunit supports remote configuration by a host computer, enabling remote video monitoring and sharing. The added units improve system stability and functional integration, optimize user experience, and make operation more convenient and data management more flexible. Although facing challenges related to compatibility, interference, and cost, appropriate strategies can ensure system performance and competitiveness, increasing applicability to complex environments.
[0065] Furthermore, based on the first aspect, this application provides an embodiment of a video encoding apparatus, aiming to provide a means of implementing video encoding equipment. Please refer to... Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the device selection for the video encoding apparatus provided in the embodiments of this application. Figure 4 This is a schematic diagram of the structure of the video encoding device provided in the embodiments of this application.
[0066] In this embodiment, the video encoding device includes: a chassis and a cabinet; the chassis houses the video encoding equipment as mentioned in the first aspect, such as... Figure 3 As shown, the chassis is housed in a server rack; the chassis can be moved within the rack. The video processing unit is a video processing board; the power conversion unit is a power adapter; and the distribution unit is an HDMI splitter.
[0067] Understandably, a 19-inch 2U standard ruggedized chassis is used, with the entire chassis installed in a server rack. The chassis dimensions are 482mm × 88mm × 300mm (width × height × depth). Server racks typically provide protection for internal equipment, offer reasonable installation space, and facilitate cabling and management. Placing the chassis in a server rack leverages these characteristics to provide a relatively stable and secure working environment for the video encoding equipment.
[0068] It should be noted that the chassis adopts a fully shielded design. The chassis frame is made of aluminum alloy vacuum brazing. The joint surface between the frame and the upper and lower cover plates uses conductive rubber strips and increases the depth of the crimped gaps to improve the shielding effectiveness of the gaps. Each component of the chassis undergoes conductive anodizing surface treatment. The joints between chassis structural components are protected with adhesive to ensure good connection between the interface and the grounding post, ensuring electrical continuity at the connection and providing a fast discharge path for static electricity, thereby protecting the equipment.
[0069] The chassis includes a rear panel; the rear panel is equipped with 6 aviation sockets, 1 grounding post and 2 positioning pins; the aviation sockets are connected to the power supply interface 13; the grounding post is used for grounding the chassis lead wires; the positioning pins are used for positioning and fixing the chassis in the cabinet.
[0070] Among them, the aviation socket adopts a round socket that is resistant to marine environments and has the ability to resist moisture, heat, mold and salt spray; the power interface aviation socket uses XC158 series connectors, the HDMI and USB interface aviation sockets use YMX series connectors, and the Ethernet interface aviation socket uses YMT series connectors. This series is easy to plug and unplug and has a reliable connection.
[0071] The chassis includes a front panel; the front panel is equipped with two metal handles, two retaining screws, one external hard drive interface, one record button, one record indicator light, one power switch, and one power indicator light. The metal handles facilitate pushing and pulling the chassis in the rack, and the retaining screws secure the chassis in the rack. The external hard drive interface connects to the video processing unit for connecting an external hard drive for convenient video storage. The record button and record indicator light are connected to the video processing unit; the record button controls the start and stop of video recording, and the record indicator light indicates the recording status. The power switch and power indicator light are connected to the power conversion unit; the power switch controls the power supply and shutdown of the device, and the power indicator light indicates the device's power supply status.
[0072] In this embodiment, the video encoding device employs a ruggedized chassis. Through structural reinforcement and aviation-grade connector design, the reliability of electrical connections is improved, preventing product malfunctions caused by poor contact due to vibration, transportation, or temperature changes. The filtering unit, isolated power supply unit, HDMI optical-to-electrical unit, HDMI distribution unit, video processing board, aviation connector, switches, and indicator lights all feature tri-proof design. Furthermore, the ruggedized chassis achieves overall tri-proof performance through structural sealing, aviation connector sealing, and external protective coating design.
