Patent number: 8516042Abstract: A client repeatedly transmits a firmware request including an obtaining start address and an obtaining data length. The obtaining start address indicates the first address of firmware data to be obtained from the server by the client. The obtaining data length indicates the length of the firmware data to be obtained from the server by the client with respect to each firmware request. The server receives the firmware request from the client repeatedly and returns the firmware data for the obtaining data length from the obtaining start address with respect to each firmware request. The client further obtains the firmware data returned from the server repeatedly and updates the firmware by using the firmware data obtained from the server.Type: GrantFiled: January 19, 2012Date of Patent: August 20, 2013Assignee: Onkyo CorporationInventors: Fumiaki Kawamura, Youichi Kudoh, Susumu Takemura, Yasushi Ikeda, Toshinobu Sano, Hiroko Yoshizaki, Takahiro Chiba

Publication number: 20130129112Abstract: A transmitting apparatus transmits contents data of the same contents in the same reproducing positions to the respective receiving apparatuses at the same time. The receiving apparatuses specifies a reception start time at which contents data of next contents is first received, and adds a same delay time set in each of the receiving apparatuses to the reception start time so as to set a reproduction start time of next contents. The receiving apparatuses end the reproduction of the on-reproducing contents at the reproduction start time, and starts reproduction of the contents data of the next contents. Therefore, even when the reproducing positions slightly shift from each other among the receiving apparatuses during reproduction of the contents, the reproduction start times of the next contents can be synchronized with each other among all the receiving apparatuses.Type: ApplicationFiled: April 30, 2012Publication date: May 23, 2013Applicant: Onkyo CorporationInventor: Susumu TAKEMURA

Patent number: 7739716Abstract: While a client reproduces a moving picture, and fast-forward reproducing is carried out in the process of reproducing a moving picture based on a frame, the client transmits a search request to a server. The server searches for the frame of I picture based on a condition in the search request in the fast-forwarding direction (reproducing direction) from the frame. The server uses a search table it has. As a result of the search, the server sequentially extracts frames of I picture and transmits them to the client. The client reproduces the frames every time it receives one of them. Therefore, a network AV system allows the memory capacity of a client to be reduced as much as possible and capable of special reproducing such as fast-forward reproducing and reverse-reproducing.Type: GrantFiled: November 12, 2004Date of Patent: June 15, 2010Assignee: Onkyo CorporationInventor: Susumu Takemura

Patent number: 7418473Abstract: All port numbers are set at a server, whereas only one port number is set at a client. The client searches for the server by using the set port number. The server responds to searching by the client and notifies the client of the other port number that is not set at the client. The client establishes the communication with the server by using the notified port number. This makes it unnecessary to set all port numbers at the client. It is therefore possible to provide a server client system with time for setting a port number decreased.Type: GrantFiled: October 10, 2003Date of Patent: August 26, 2008Assignee: Onkyo CorporationInventors: Susumu Takemura, Yasushi Ikeda, Koichi Kato

Patent number: 7167879Abstract: An uploader transmits to a server a request start notification indicating the start of a registration request and then transmits to the server a plurality of registration requests for pieces of music piece data. Upon receiving the plurality of registration requests from the uploader, the server registers the pieces of music piece data in a database in an HDD. After transmitting all the registration requests, the uploader transmits to the server a request completion notification indicating the completion of the registration requests. The server transmits an updating notification to an audio client after receiving the request completion notification. Therefore, traffic between the server and the client can be reduced when the server updates the database.Type: GrantFiled: October 12, 2004Date of Patent: January 23, 2007Assignee: Onkyo CorporationInventors: Toshinobu Sano, Susumu Takemura, Yasushi Ikeda
