With the rapid development of educational informatization, remote training, and smart conferencing, the demand for high-quality audio and video recording and live streaming is growing. Traditional recording and broadcasting systems often rely on the coordinated operation of multiple devices: cameras for acquisition, encoders for signal transmission, director consoles for screen switching, and recorders for content storage. This results in a complex system structure, high costs, and difficult maintenance. However, technological advancements have led to the emergence of the simple recording and broadcasting terminal, which integrates audio and video acquisition, encoding and decoding, processing, recording, live streaming, directing, interactive content, and maintenance management into a single device, truly achieving the "one device, one system" goal. One of its most notable features is its built-in video directing capability, enabling users to achieve intelligent multi-screen switching and high-quality video output without the need for a dedicated director console.1. Hardware Integration: Providing a Strong Foundation for Directing FunctionsThe simple recording and broadcasting terminal's ability to deliver directing functionality is primarily due to its high-performance hardware platform. The device typically features multiple HD video inputs, allowing simultaneous access to multiple signal sources, including panoramic teacher footage, close-up student footage, blackboard footage, and courseware computers. The built-in high-performance processor boasts powerful parallel processing capabilities, enabling real-time decoding, scaling, synthesis, and encoding of multiple 1080P and even 4K video streams, providing a solid computing foundation for screen switching. Furthermore, the device's integrated audio mixing module synchronizes audio signals from multiple microphones and line-in inputs, ensuring synchronized audio and video with clear sound quality, while avoiding the delays and asynchrony issues often associated with external devices in traditional systems.2. Software Intelligence: Automated Directing and Policy SwitchingThe core directing functionality is implemented by the terminal's built-in intelligent directing software engine. This engine supports multiple directing modes, including fully automatic, semi-automatic, and manual, to meet diverse scenario requirements. In fully automatic mode, the system automatically determines the timing of screen switching based on pre-set logic. For example, in a smart classroom, when the teacher's movement is detected, the system automatically switches to a close-up of the teacher; when the teacher returns to the podium or writes on the blackboard, the system switches to the blackboard; and when a student stands up to speak, the system automatically switches to the student area. These decisions can be triggered through image recognition, sound location, or external central control signals, enabling "unmanned" intelligent directing. The system also supports pre-set directing strategies, allowing users to customize switching rules, transition effects, and screen layouts, save them as templates, and access them with a single click. For example, lecture mode can be set to dual-screen with the speaker's screen and PowerPoint presentations, while discussion mode switches to a multi-screen rotation, greatly enhancing application flexibility.3. Convenient Operation: Combining Local and Remote ControlWhile eliminating the need for an external directing console, the simple recording and broadcasting terminal offers multiple control methods. Users can remotely operate the terminal through the device's built-in web management interface, a dedicated control panel, or a mobile app, allowing real-time monitoring of various feeds, manual switching of the main feed, and adjustment of directing strategies. Some devices also support triggering directing actions via the central control system or the one-touch recording and broadcasting panel, achieving seamless integration with the teaching process. Furthermore, all directing operations are logged for easy traceability and optimization, enhancing system manageability.4. Integrated Advantages: Reduced Costs and Improved Deployment EfficiencyThe greatest advantage of integrating directing functions into the recording and broadcasting terminal lies in system simplification and cost reduction. Traditional solutions require the purchase of additional equipment such as a director console, video matrix, and monitors, which not only increases budget, space, and cabling complexity, but also increases costs. The simple recording and broadcasting terminal, however, integrates all of these features into one device, reducing the number of devices and points of failure, resulting in faster deployment and easier maintenance. It is particularly suitable for large-scale, standardized classrooms, conference rooms, or training centers.Through a combination of "hardware integration + software intelligence," the simple recording and broadcasting terminal integrates directing functions, previously performed by independent devices, into the system, enabling autonomous control of the entire process from signal acquisition to video output. This not only reduces user deployment and maintenance costs, but also improves system stability and intelligence. In the wave of digital transformation that pursues efficiency, convenience and low cost, this integrated and lightweight solution is becoming an important force in promoting the popularization of recording and broadcasting technology.
