ABSTRACT:
An audio bit stream generator for an HDTV utilizing a PC, including: a hard disc for storing an HDTV audio data encoded and prepared through computer stimulations; an input/output bus; a first-in first-out (FIFO) memory; a status register for controlling the input/output bus; a PC with main memory for reading a certain amount of the audio data and for outputting the data to the input/output bus; an address decoder section for analyzing output addresses of the input/output bus, and for controlling the FIFO memory and the status register section. The FIFO memory stores 8-bit data from the input/output bus and for outputs modified 8-bit data to a parallel/serial converter. In addition to the parallel/serial converter, the audio bit stream generator further includes: a memory read/write control section for controlling read/write operations of the FIFO memory; a switch for controlling reading operations of the FIFO memory under a control of said memory read/write control section; and a clock generating section for generating transmission clocks used in conjunction with the parallel/serial converter, which converts 8-bit data to 1-bit data, thereby forming the audio bit stream. In another aspect, the invention is a method for controlling an audio bit stream generator by utilizing a PC.
