The AT72XUSB is a USB based interface device suitable for Recording and Analyzing of DVB-C (annex b) or 8VSB Transport Streams.

The device communicates with the USB bus via the USB interface device. The RF signal is demodulated and then de-coded before entering the PC via the main controller and the USB bus as Full TS files. The main controller transfers the incoming Transport Stream to the application for recording via the hardware buffer, the USB controller and software buffer.

The most commonly used feature of the AT72XUSB is its ability to demodulate the DVB-C (annex b) or 8VSB signal into the onboard DVB-ASI output in real-time.
