Abstract

A broadcast text data sampling apparatus comprises an A/D converter for sampling a broadcast text signal supplied from the outside, with a sampling clock of a predetermined frequency, to convert the text signal into digital data; a binarization circuit for converting the digital data into a binary signal; a sampling pulse generation circuit for detecting the cycle of clock run-in of the broadcast text signal from the binary signal, obtaining a text data sampling interval value on the basis of the clock run-in cycle, sequentially calculating the positions of data in the binary signal, which data are positioned at intervals close to the sampling interval value, starting from a predetermined sampling start position, and generating a sampling pulse that designates the calculated data positions as data sampling positions; and a sampling circuit for sampling the text data from the binary signal on the basis of the sampling pulse. Therefore, this data sampling apparatus is able to perform sampling of text data from plural types of text broadcastings having different transmission clock frequencies.
