Embodiment Construction
[0047] An embodiment of the present invention is described below. In FIG. 1, the communication device 12 of the present embodiment includes an S / P converter 120, a timing detector 130, a selector 140, an encoder 106, a digital filter 108, a D / A converter 110, and a low-pass filter 112. , and a differential driver 114 . Please note that in FIG. 1 the same components as those of the communication system shown in FIG. 10 are provided with the same reference numbers and will not be described here.
[0048] As in FIG. 10 , input data (biphase-encoded serial data) constituted by S / PDIF frames is supplied to the communication device 12 . The S / P converter 120 converts this serial data from serial to parallel every two bits at different timings, thereby outputting two kinds of parallel data.
[0049] FIG. 2 shows the structure of the S / P converter 120 . The S / P converter 120 includes two flip-flop circuits and a latch circuit for outputting two kinds of parallel data converted from...
