After many tests confirmed that the TMB300A can not achieve HDMI and AV output video at the same time, can only switch TV HDMI for other or unplug the box HDMI interface to achieve the AV output video, in order to share the set-top box in the living room and bedroom how to do it?
First, the physical connection:
The set-top box is placed in the living room, and the HDMI and AV composite terminals are connected at the same time; the AV composite terminal uses the lotus two points to connect the living room TV and the AV cable converter; because the living room-to-bedroom TV has the same network cable, the network cable is used to transmit the AV signal; End cable to AV to TV;

Toroidal Transformers, also known as Ring Transformers, are a type of electrical transformer that utilizes a toroidal (donut-shaped) core for magnetic flux circulation. This unique core design offers several advantages over traditional transformer core shapes, making toroidal transformers an attractive choice for various applications.
Key Applications of Toroidal Transformers
Efficiency and Low Losses:
The toroidal core shape minimizes flux leakage and eddy current losses, resulting in higher efficiency compared to other transformer types. This makes toroidal transformers ideal for applications where energy conservation is crucial, such as power supplies for electronic devices, audio equipment, and renewable energy systems.
Compact Size and Lightweight:
Due to their efficient core design, toroidal transformers can achieve higher power densities, allowing for more compact and lightweight constructions. This makes them suitable for space-constrained applications, such as portable electronics, automotive systems, and aircraft instrumentation.
Low Electromagnetic Interference (EMI):
The toroidal core shape naturally cancels out much of the magnetic field radiated by the transformer, reducing electromagnetic interference (EMI). This feature is particularly beneficial in applications where sensitive electronics are present, such as audio and video systems, medical devices, and telecommunications equipment.
Audio Applications:
Toroidal transformers are widely used in audio equipment due to their low noise and distortion characteristics. They provide clean and stable power to audio amplifiers, preamps, and other audio components, ensuring high-fidelity sound reproduction.
Power Supplies:
Toroidal transformers are commonly used in power supply units for various electronic devices, including computers, servers, and industrial equipment. Their high efficiency and low EMI make them well-suited for powering sensitive electronic circuits.
Renewable Energy Systems:
In renewable energy systems such as solar power plants and wind turbines, toroidal transformers are used for power conversion and distribution. Their compact size and high efficiency make them an attractive choice for integrating into these systems.
Medical Equipment:
Medical devices often require precise and reliable power supplies to ensure patient safety and accurate measurements. Toroidal transformers provide clean, stable power with low EMI, making them suitable for use in medical equipment such as patient monitors, diagnostic machines, and therapeutic devices.
Industrial Automation:
In industrial automation systems, toroidal transformers are used to power sensors, actuators, and other electrical components. Their compact size and high efficiency make them ideal for integration into automation control panels and machinery.
Conclusion
Toroidal transformers offer a unique combination of advantages, including high efficiency, low losses, compact size, lightweight construction, and low EMI. These features make them an attractive choice for a wide range of applications, from audio equipment to renewable energy systems. As technology continues to evolve, toroidal transformers will continue to play a crucial role in powering our world's electronic devices and infrastructure.
