Description

Technical Field

[0001] This utility model relates to the field of encoder technology, and more specifically, to an encoder based on a wired network. Background Technology

[0002] Currently, the mainstream live streaming device for individual users is basically a mobile phone. However, some individual users use an external camera connected to their phone for live streaming in order to obtain higher-definition video. The camera is responsible for video recording, and the signal is transmitted to the mobile phone via an adapter cable, and then the mobile phone connects to the internet to achieve live streaming. The mobile phone mainly relies on Wi-Fi or mobile data networks for internet access, and both use wireless connections.

[0003] However, wireless networks have many uncontrollable factors that pose significant challenges to live video transmission. Channel congestion, signal interference, distance, and physical obstacles all greatly affect wireless network signal transmission. For example, in densely populated areas, the simultaneous use of numerous wireless devices can lead to channel congestion, drastically reducing data transmission speed and causing stuttering during live video transmission. Similarly, the presence of nearby microwave ovens, Bluetooth devices, or other electronic devices can interfere with the mobile phone's network signal, severely impacting the quality of signal reception and transmission, resulting in distorted or blurry images on the terminal display. Furthermore, if the live broadcast location is far from the wireless router, or if there are obstacles such as walls or metal objects in between, signal strength will decrease with distance. Physical obstacles can also cause reflections and refractions, leading to unstable signal transmission. These problems are even more pronounced when transmitting high-definition (HD) video. HD live broadcasts involve massive amounts of data, demanding higher stability and speed from the network, and these inherent limitations of wireless networks make it difficult to meet the high-quality live video transmission needs of these users. Summary of the Invention

[0004] To address the issue of mobile wireless networks affecting the quality of live streaming, this invention provides a wired network-based encoder that replaces the connection between the mobile phone and the external camera. It uses a wired RJ45 network to transmit video signals, thereby avoiding all the drawbacks of wireless networks and obtaining higher quality and more stable live streaming footage.

[0025] 1. The encoder uses an RJ45 wired network link for transmission, replacing wireless transmission devices such as mobile phones.

[0034] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0035] An encoder based on a wired network includes a housing 1 and a circuit board built into the housing. The housing has multiple holes, allowing components connected to the multiple circuit boards to be exposed and protruding from or flush with the housing surface. The circuit boards are connected to a network interface, a USB interface, and a video data input interface, respectively. The circuit boards are equipped with an encoding processor and a wired network processor. The encoding processor is connected to the wired network processor, the USB interface, and the video data input interface. The wired network processor is connected to the network interface. A video signal source sends a video source signal to the encoding processor via the video input interface. The encoding processor sends an encoded signal to the wired network processor. The wired network processor sends the encoded signal to the network via the network interface.

[0036] like Figure 1 , Figure 2 As shown, the encoder is equipped with a display screen 2, control buttons, a power button 6, a DC power interface 7, a PoE LAN network interface 8, a TF card interface 9, a microphone interface 10, a headphone interface 11, a USB interface 12, an HDMI signal loop-out interface 13, an HDMI input interface 14, an SDI signal loop-out interface 15, an SDI input interface 16, and an antenna 17. The display screen, PoE LAN network interface, TF card interface, microphone interface, headphone interface, USB interface, HDMI signal loop-out interface, and HDMI input interface are all exposed and flush with the surface of the housing, while the control buttons, power button, DC power interface, SDI signal loop-out interface, SDI input interface, and antenna are exposed and protrude from the surface of the housing.

[0037] like Figure 1 As shown, on the front of the encoder housing, from left to right, are the display screen and control buttons (from top to bottom: up arrow button 3, confirmation button 4, and down arrow button 5). Figure 2As shown, on the back of the encoder housing, from left to right, are the power button, DC power interface, PoE LAN network interface, TF interface, microphone interface, headphone interface, USB interface (there are two USB interfaces, both of which are USB Type A interfaces), HDMI signal loop-out interface, HDMI input interface, SDI signal loop-out interface, and SDI input interface. Two upward-facing antennas are set above these buttons or interfaces.

[0038] The circuit board is also connected to a power button and a DC power interface, which are exposed and protrude from the housing surface. The DC power interface connects to a 12V DC power supply. The 12V DC power interface is compatible with industry standard power supply systems. Furthermore, the encoder of this invention uses DC power as its primary energy source, simplifying the power supply filtering circuit design and improving energy efficiency.

[0039] The circuit board is also connected to the display screen, which is flush with the housing surface. The circuit board is also connected to control keys, including an confirmation key, an up arrow key, and a down arrow key, which protrude from the housing surface. Users control the cursor on the display screen using the control keys to perform various controls or operations. The display screen provides users with visual operation, showing the encoder's operating status and configuration interface, providing a real-time system diagnostic interface, supporting dynamic parameter adjustment, and lowering the barrier to professional operation and maintenance.

[0040] The circuit board also connects to a USB interface, which consists of two USB Type-A ports, supporting connection to control terminals and storage devices.

[0041] The network interface is a PoE LAN network interface. The PoE LAN network interface transmits power and data synchronously through twisted-pair cables, which is particularly suitable for scenarios that require simplified cabling, such as when networking codecs in a mobile broadcasting vehicle. PoE power supply can avoid the space occupation caused by multiple device power adapters and meet the needs of rapid deployment.

[0042] The circuit board houses a wireless network processor, which connects to the network via an antenna that extends to the exterior of the housing. This processor allows the encoder to adapt to a wider range of network environments, ensuring device availability in areas with insufficient wired network coverage or in live streaming scenarios requiring frequent movement. In the event of a wired network failure or unavailability, the wireless network processor serves as a backup network access method, ensuring uninterrupted live streaming and improving system reliability and fault tolerance.

[0043] The circuit board is also connected to a signal loop-out interface, through which the encoding processor sends encoded signals to downstream devices. Both the signal loop-out interface and the video data input interface include HDMI and SDI interfaces. The signal loop-out interface can output the encoder-processed signal to multiple display devices, enabling multi-screen display. This invention can also be applied in complex live streaming or recording environments to transmit signals to multiple different devices or systems. The signal loop-out interface provides a flexible solution for this, allowing the encoder to be seamlessly integrated into larger audio-visual systems. Furthermore, through the signal loop-out interface, users can transmit signals to other devices for backup, recording, or real-time processing without interrupting encoder operation, thus achieving multi-tasking parallel processing.

[0044] The circuit board connects to external audio devices via microphone and headphone jacks to acquire more audio data.

[0045] The circuit board also connects to a TF card interface. This interface allows the encoder to directly store processed audio and video data onto the TF card, providing additional data backup and reducing the risk of data loss due to network transmission failures or platform storage issues. Furthermore, audio and video files stored on the TF card can be edited, analyzed, or archived offline, facilitating further user processing. In cases of unstable or interrupted network transmission, the TF card can serve as a temporary storage medium to save data that was not successfully uploaded. Once the network is restored, this data can be re-uploaded, ensuring the integrity of the live stream content. With data stored on the TF card, the encoder can achieve separation of storage and transmission; even under poor network conditions, data will not be lost, and users can retrieve the data later through other methods (such as USB transfer, local reading, etc.).

[0046] Anti-slip blocks 18 are installed at the four corners of the bottom surface of the housing. The silicone pads at the four corners of the bottom of the housing provide equipment-level shock resistance, making it suitable for vibration environments such as mobile broadcasting vehicles.

[0047] like Figure 3As shown, the encoding processor first samples the input signal. Sampling refers to taking samples of the continuous input signal within a certain time interval, converting the input signal into a discrete digital signal. The higher the sampling frequency, the closer the converted digital signal is to the original signal. The sampled signal then undergoes quantization, which is the process of converting the continuous input signal into a discrete digital signal. It approximates the sampled signal with a certain quantization step size. The higher the quantization accuracy, the closer the output digital signal is to the original signal. Next, the encoding processor encodes the quantized signal according to specific encoding rules for easy transmission and storage. Common encoding methods include lossless encoding and lossy encoding. Finally, the encoding processor outputs the encoded signal, which is transmitted to the network via a wired RJ45 network link through a wired network processor. Then, according to the network's real-time information transmission protocol, a handshake is performed, a connection is established, a stream is created, and the signal is pushed to various live streaming platforms. These platforms then stream the signal to users, and the final image is displayed on the user's screen.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
