20090207232MULTIPOINT CONFERENCE SYSTEM, MULTIPOINT CONFERENCE METHOD, AND PROGRAM - A multipoint videoconference server is made to swiftly respond to a video switching request from a terminal and a degree of computational complexity is made lower. A server 08-20-2009
20090313676BUFFER CONTROL METHOD, RELAY APPARATUS, AND COMMUNICATION SYSTEM - Disclosed is a relay apparatus including a video buffer control unit that controls a video buffer according to a control instruction received by an instruction receiving unit, a threshold set by a threshold setting unit, and a timing set by a timing generation unit. The video buffer control unit controls the video buffer for each segment, according to a result of analysis by a segment interpretation unit.12-17-2009
20100022265PTT SERVER, PTT COMMUNICATION SYSTEM, PTT COMMUNICATION METHOD, AND PROGRAM - A PTT server includes a controlling unit, a receiving unit, a medium converting unit, and a transmitting unit. The controlling unit controls pieces of connection setting information less than the number of a plurality of PTT terminals having different specifications by complying them with the plurality of PTT terminals. The receiving unit receives a medium coded data from any one of the PTT terminals. The medium converting unit converts the medium coded data with a converting method on the basis of the connection setting information compliant with a PTT terminal for transmission destination to produce an output coded data. The transmitting unit transmits the output coded data to the PTT terminal for the transmission destination.01-28-2010
20100128715Protocol Conversion System in Media Communication between a Packet-Switching Network and Circuit-Switiching Network - In media communication by way of a packet-switching network and a circuit-switching network, a protocol conversion device for converting protocols between the packet-switching network and the circuit-switching network includes a call connection unit and a protocol converter. The call connection unit carries out call connection processes of media communication between terminals of the packet-switching network side and terminals of the circuit-switching network side. The protocol converter analyzes packets of speech received from the packet-switching network to specify the encoding bit rate of speech data in the speech packets. The protocol converter then specifies the multiplex table used in multiplexing frames on the circuit-switching network from the encoding bit rate. The protocol converter further generates frames by using the multiplex table that was specified to multiplex data in the payload of packets received from the packet-switching network and transmits to the circuit-switching network.05-27-2010
20110055658CONTENT DISTRIBUTION METHOD, ENCODING METHOD, RECEPTION/REPRODUCTION METHOD AND APPARATUS, AND PROGRAM - There are provided a content data transmission method, device, and program that minimize serious disturbances in reproduced content on the reception side, caused by a transmission error of encoded data, without sending feedback information from the reception side to the transmission side. When an encoder 03-03-2011
