Embodiment Construction

[0060] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Note that two systems will be described, namely, a system for inputting an audio signal from a wireless microphone to a video camera or a sound mixer during ENG (Electronic News Gathering), and a system in which multiple wireless microphones are used in a studio to transmit multiple A system of audio signals on channels.

[0061] System for inputting audio signals to cameras

[0062] Fig. 4 is a diagram showing one example of an audio delivery system to which an embodiment of the present invention is applied. This system inputs audio transmitted using a wireless microphone to a camcorder (ie, a video camera integrated with a recorder) to record audio during ENG (Electronic News Gathering).

[0063] Wireless microphone transmitters (hereinafter simply referred to as "transmitters") are used by broadcasters who conduct interviews. Although a hand-...

Abstract

THe present invention provides a wireless audio transfer system and a wireless microphone. The wireless audio transfer system that includes an audio transmitting apparatus including a microphone and a modulating / transmitting unit for transmitting radio waves modulated using an audio signal from the microphone, an audio receiving apparatus including a receiving / demodulating unit for receiving the radio waves and demodulating the audio signal, and an audio output terminal for outputting the audio signal demodulated by the receiving / demodulating unit. The system further includes an image pickup apparatus including an audio input terminal for inputting the audio signal. In the system, the audio transmitting apparatus includes a detecting unit for detecting distortion of an audio signal and a data transmitting unit for transmitting status data, the audio receiving apparatus includes a first communication terminal and a data processing unit for obtaining the status data from the received radio waves and outputting the status data from the first communication terminal, and the image pickup apparatus includes a second communication terminal for inputting the status data outputted from the first communication terminal, a display unit, and a first control unit for displaying whether audio distortion is present at the audio transmitting apparatus.

Description

technical field [0001] The present invention relates to a system for transmitting audio to a camera, recorder, or audio mixer using a wireless microphone, and also relates to a wireless microphone, an audio transmitter, an audio receiver, a camera, a recorder constituting the system and mixer. Background technique [0002] In recent years, the use of wireless microphones to transmit audio has become common in television broadcasting. Figure 1A and 1B Two examples of the appearance of the wireless microphone are shown. In these two figures, Figure 1A A wireless microphone transmitter (hereinafter simply referred to as "transmitter") is shown as means for transmitting audio. Each transmitter 81, 82 basically comprises a microphone (in the case of the transmitter 82, a jack microphone connected by a cable, not shown) and a modulating / transmitting unit which transmits the The audio signal (audio signal) is modulated radio waves. The transmitter 81 is a handheld microphone ...
