Patent number: 6785230Abstract: In an audio transmission apparatus used in an asynchronous communication network, a receiving buffer stores temporarily an audio packet received in a network interface section. This audio data is decoded in an audio decoder, and is passed through a D/A converting speed changer, and the digital audio data is converted into analog in a D/A converter. Concurrently, in a delay time fluctuation measuring section, the delay time fluctuation of audio packet received is measured in the network interface section, and a buffer controller determines the data storage amount of the receiving buffer on the basis of this delay time fluctuation. Accordingly, the buffer controller changes the D/A converting speed on the basis of the delay time fluctuation, thereby adjusting the audio data flow from the receiving buffer. Accordingly, a real-time audio transmission apparatus capable of avoiding lack of audio data in the buffer and reproducing audio continuously is presented.Type: GrantFiled: May 23, 2000Date of Patent: August 31, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Keisuke Ogata, Yutaka Takeda
