摘要： A hybrid architecture of a television (TV) receiving system is disclosed. The architecture includes two portions, a hardware portion and a software portion. The hardware portion includes a minimum amount of hardware to achieve operations of receiving a RF signal, producing an IF signal and outputting data representing the IP signal. The software portion, taking advantage of available computing power (e.g., high-speed microprocessor and a lot of memory) in a computing device and executed therein, includes one or more demodulators, all implemented in software. Each of the demodulators is implemented in accordance with one type of TV standard. Thus depending on the received data, a corresponding demodulator is activated to demodulate the received data and subsequently produces audio and video data. One of the advantages, benefits and objects in the present invention is to have a band of software-based demodulators, any of which may be updated or expanded whenever there is a new TV standard or modification to an existing standard.

The rotary disk further provides the photo interruption sets. Two photo-interrupters are disposed under the first photo interruption set for detecting the rotational direction and rotational displacement of the rotary disk. The third photo-interrupter is disposed under the second photo interruption set for detecting the absolute rotational angle of the rotary disk.
