Patent number: 7664060Abstract: 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.Type: GrantFiled: November 18, 2005Date of Patent: February 16, 2010Assignee: Panasonic CorporationInventors: Tomiya Miyazaki, Yutaka Takeda, Kazuo Yahiro, Takuji Tsujigawa, Naoki Koga, Keisuke Ogata, Akitoshi Aritaka

Patent number: 7444391Abstract: 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.Type: GrantFiled: April 30, 2004Date of Patent: October 28, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Tomiya Miyazaki, Kazuo Yahiro, Toru Imamura, Masafumi Tanaka, Yutaka Takeda, Keisuke Ogata, Takuji Tsujigawa, Akitoshi Aritaka

Patent number: 6377569Abstract: An Internet phone server device includes a database storing users' telephone numbers and nearby ISPA information, a telephone number acquiring unit for acquiring the telephone number of the other party in response to user's call origination, an ISPA acquiring unit for obtaining the nearby ISPA of the terminating side from the acquired telephone number, and an ordinary public line calling unit for originating a call to a terminating Internet phone from the ISPA of the terminating side by using an ordinary public line. At an arbitrary time, the user originates a call. Even if the other-party does not communicate using IP connection, an communication can be effected.Type: GrantFiled: December 23, 1997Date of Patent: April 23, 2002Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takuji Tsujigawa, Daisuke Wada
