Abstract

PURPOSE:To realize the selection of a proper encoded algorism, by recording the encoded algorism on the receiving copy to the decoded data and as a result making clear the relation between the state of occurrence of an error and the encoded algorism. CONSTITUTION:An encoded data including a synchronizing code, a data bit, a filled bit and an RTC code is demodulated by a demodulator 1. The demodulated data is encoded by a decoder 2. This encoded data is recorded at a recording part 3. A line buffer 22 is provided to the decoder 2, and the pattern information that is decided previously to display the type of the encoded algorism of the decoded encoding data is stored in the form of an RL. Then the supplied encoded data is decoded through a decoding part 21, and an RTC code is detected. The reproduced teleautogram information which is so far decoded is delivered to the part 3. Thereafter, the pattern information corresponding to the type of the encoded algorism is read out of the buffer 22 and then delivered to the part 3.
