The USB HDTV Receiver adapted AU8522 is a DTV demodulation IC for ATSC, digital cable, and legacy TV applications. Internally, the AU8522 consists of a fully compliant ATSC A/74 8-VSB demodulator, a 64/256 QAM demodulator, a complete NTSC analog TV demodulator and video decoder, and a BTSC/A2/FM audio decoder. The AU8522 directly accepts IF or low IF from the RF tuner section via a 12-bit internal Analog-to-Digital Converter, and following demodulation and error correction, outputs MPEG-2 transport stream. The AU8522 utilizes Auvitek's proprietary demodulation algorithms and adaptive signal-tracking architecture to offer market-leading receiver performance. The AU8522 is ideally suited for any DTV or PC-TV system that requires full support for legacy TV broadcast alongside DTV reception.

The USB All-DTV Receiver has Time-Shifting function which enables you pausing live digital (ATSC) TV and resume wherever you paused. It also has scheduled-recording function that keeps you from missing your favorite TV programs. With just one-touch click, you can record digital TV perfectly to MPEG-2 format!
