摘要： An information terminal incorporates a network interface and an extension interface, and in the case of outside call, an audio send signal is modulated into an audio signal frequency band, and sent to the exchange through a private telephone line and a subscriber's line by way of the network interface. An audio receive signal sent from the exchange through the subscriber's line and private telephone line is demodulated into an ordinary audio frequency band through the network interface. On the other hand, in the case of extension service, an audio send signal is converted into a packetized digital signal by an extension interface circuit, and is further modulated into a higher frequency band so as not to overlap with the audio signal frequency band, and is transmitted through the private telephone line.

摘要： A data terminal, a data distributing system, and an Internet telephoning system are provided where desired data such as advertisements can selectively be determined and used for enjoying its relevant services. The data terminal receives a summary of service data from a data provider apparatus over the Internet, and if desired, demands the data provider apparatus to provide the service data over the Internet. The service data from the data provider apparatus may selectively be received in at least one of an audio form, a text form, and a video form at the data terminal. The service data may be advertisement data, commercial product data, and entertainment data such as music, movies, and games. The entertainment data may selectively be presented as at least one of the title, the artist name, the cost, and a trial sample piece of the content.

摘要： 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.
