This utility model relates to the field of digital television technology, specifically to a dual-tuner USB TV stick circuit, including an antenna interface. Through the design of first and second dual tuners and dual demodulation circuits, it achieves parallel frequency selection, amplification, and demodulation of two terrestrial broadcast digital television signals, supporting users to watch two programs simultaneously or record another program while watching the first. This overcomes the functional limitations of single-tuner devices, greatly improving the flexibility and diversity of program reception. The low-noise amplifier (LNA) in the signal amplification circuit performs noise reduction and amplification on the signal received by the antenna, ensuring signal quality. The signal conversion circuit converts the TS stream signal into a USB signal, which is then separated and transmitted via a USB hub circuit, ensuring stable signal flow within the device, reducing signal loss and interference, and providing a high-quality signal source for subsequent playback and recording. The SD / TF card recording circuit, in conjunction with the USB hub circuit, enables local storage of the program stream, eliminating the need for users to rely on the main device's memory space.
