Claims (5)

テレビから入力される音声信号をスピーカーに出力するＡＲＣ機能を有する音声処理装置であって、
前記テレビから入力される機器間転送するための規格に従った第１デジタル音声信号を、シリアル転送するための規格に従った第２デジタル音声信号に変換する変換部と、
前記第２デジタル音声信号にデジタル信号処理を行う信号処理部と、
制御部と、を備え、
前記制御部は、前記スピーカーから音声が出力されていない異常状態であると判断した場合に、ＡＲＣ機能オフのコマンドを前記テレビに送信し、前記テレビに接続されている電源ラインをローレベルにした後、ハイレベルとし、ＡＲＣ機能オンのコマンドを前記テレビに送信することを特徴とする音声処理装置。 An audio processing apparatus having an ARC function for outputting an audio signal input from a television to a speaker,
A conversion unit for converting a first digital audio signal in accordance with a standard for transferring between devices input from the television into a second digital audio signal in accordance with a standard for serial transfer;
A signal processing unit for performing digital signal processing on the second digital audio signal;
A control unit,
When it is determined that the control unit is in an abnormal state in which no sound is output from the speaker , the control unit transmits an ARC function off command to the television and the power line connected to the television is set to a low level. Thereafter, the audio processing apparatus is set to a high level and transmits an ARC function ON command to the television. 前記制御部は、前記テレビと所定規格に従った通信を行っており、自装置の内部状態がＡＲＣ機能を実行する状態であり、前記変換部が前記第１デジタル音声信号をロックしており、且つ、前記信号処理部が前記第２デジタル音声信号をロックしていない状態が、所定時間継続した場合に、前記異常状態であると判断することを特徴とする請求項１に記載の音声処理装置。   The control unit communicates with the television according to a predetermined standard, the internal state of the device is a state in which the ARC function is executed, the conversion unit locks the first digital audio signal, 2. The audio processing apparatus according to claim 1, wherein when the state in which the signal processing unit does not lock the second digital audio signal continues for a predetermined time, it is determined that the abnormal state is present. . 前記所定規格は、ＣＥＣ規格であることを特徴とする請求項２に記載の音声処理装置。   The audio processing apparatus according to claim 2, wherein the predetermined standard is a CEC standard. 前記第１デジタル音声信号は、ＳＰＤＩＦ信号であることを特徴とする請求項１〜３のいずれか１項に記載の音声処理装置。   The audio processing apparatus according to claim 1, wherein the first digital audio signal is an SPDIF signal. 前記第２デジタル音声信号は、Ｉ２Ｓ信号であることを特徴とする請求項１〜４のいずれか１項に記載の音声処理装置。   The sound processing apparatus according to claim 1, wherein the second digital sound signal is an I2S signal.
