Description

Technical Field

[0001] This invention relates to the field of satellite communication technology, specifically to a satellite receiving device that uses wireless transmission. Background Technology

[0002] Satellite receiving equipment refers to a system used to receive downlink signals from communication and broadcasting satellites and process them to restore them into audio, video, or data information. Typical satellite receiving equipment consists of two main parts: an outdoor unit and an indoor unit. The outdoor unit usually refers to the satellite receiving antenna (commonly known as a "dish") installed outdoors and its connected low-noise downconverter (LNB). Its main function is to gather and receive the weak microwave signals transmitted by the satellite, amplify them with low noise, and downconvert them to form an intermediate frequency (IF) signal. The indoor unit is the satellite receiver (or set-top box), whose function is to demodulate and decode the IF signal from the outdoor unit, ultimately outputting audio, video signals, or data streams that can be used by televisions, monitors, and other terminals.

[0003] In existing technologies, coaxial cables are commonly used for signal connection between outdoor and indoor units. This wired connection method has significant shortcomings in practical applications: First, installation and wiring are cumbersome, especially when the building structure is complex or long-distance wiring through walls is required, making construction inconvenient and affecting aesthetics; second, the outdoor section of the coaxial cable is exposed to a complex environment, making it prone to aging and damage over long-term use; more importantly, in thunderstorms, the metal cable connecting indoor and outdoor units may become a conduction path for lightning induced electromotive force or direct lightning current, posing a risk of introducing high voltage and high current into indoor equipment. This could not only damage expensive satellite receivers, televisions, and other equipment, but also endanger personal safety, which is a significant safety hazard of existing satellite receiving systems. Summary of the Invention

[0011] In some embodiments, the satellite receiver further includes a human-machine interface, which includes at least one of a keyboard scanning circuit, a display driving circuit, a remote control receiving circuit, and / or a standard wired communication interface.

[0012] A method for wireless transmission of satellite signals, applied to the aforementioned satellite receiving equipment, includes the following steps: The outdoor unit receives satellite microwave signals through a satellite receiving antenna. After low-noise amplification, down-conversion and analog-to-digital conversion by the LNB, the signals are transmitted wirelessly via Bluetooth through its integrated first Bluetooth signal transmission circuit.
