Abstract

Abstract Translated from Japanese (57)【要約】 【課題】音声情報に文字情報をディジタルで埋め込み、 通信をする。 【解決手段】標本化手段2と、量子化手段3と、文字情 報入力手段4と、量子化出力103を8ビットの符号に 変換し、該8ビット符号の内の下位nビット(n=3) を、音声符号104の内のnビットで置き換えることに より文字情報埋め込み音声信号105を生成する符号化 手段5と、該文字情報埋め込み音声信号105をフレー ム化してなるディジタル出力106を通信路へ送出する フレーム化手段6とを送信側に備え、多重化したディジ タル入力106を通信路から受信し、自己のチャネルの 文字情報埋め込み音声信号107を取り出すチャネル分 解手段7と、文字情報埋め込み音声信号107から文字 情報110を復号するとともに、文字情報埋め込み音声 信号108を出力する復号手段8と、信号108をアナ ログの音声信号109に変換する低域フィルタ9とを受 信側に備えてなる。 (57) [Abstract] [Problem] Digitally embedding character information in voice information, Communicate. SOLUTION: A sampling means 2, a quantization means 3, a character information input means 4, and a quantized output 103 are converted into an 8-bit code, and lower n bits (n = 3) of the 8-bit code. ) Is replaced with n bits of the voice code 104 to generate a character information embedded voice signal 105, and a digital output 106 formed by framing the character information embedded voice signal 105 is sent to a communication path. The frame decomposing means 6 is provided on the transmitting side, the multiplexed digital input 106 is received from the communication channel, the channel decomposing means 7 for taking out the character information embedded voice signal 107 of its own channel, and the character from the character information embedded voice signal 107. The receiving side is provided with a decoding unit 8 which decodes the information 110 and outputs the character information embedded voice signal 108, and a low-pass filter 9 which converts the signal 108 into an analog voice signal 109.
