Claims (1)
送する静止画伝送装置において、変調部お、よび復調部
を具備するモデムと、該モデムの受信タイミング信号を
ＤＰＣＭ符号化の量子化数分の１・に分周する分周回路
と、該分周回路の出力を前記モデムの変調部に加えて変
調した信号と外部からの入力信号とのいずれかを選択し
前記復調部へ加えるためのスイッチとを備え自己試験時
前記復調部入力として前記変調部用力を選択するように
し ゛たことを特徴とする静止画像受信機。A still image transmission device that encodes a television image signal with DPCM and transmits it using a modem includes a modem that includes a modulation section and a demodulation section, and a reception timing signal of the modem that is divided by the number of quantizations in DPCM encoding. a frequency divider circuit that divides the frequency into a frequency divider, and a switch that selects either a signal modulated by adding the output of the frequency divider circuit to a modulation section of the modem or an external input signal and applies it to the demodulation section. A still image receiver characterized in that the power of the modulating section is selected as the input of the demodulating section during a self-test.
