Patent number: 8098660Abstract: To transmit multimedia data in such a manner that is adaptive to the transmission capability of a receiving apparatus and/or to the congestion state of a network. In a transmitting apparatus (100), a receiver capability estimating part (102) estimates, based on feedback information from a receiving apparatus (200), a useable band. A receiver classifying part (103) classifies, based on the useable band, the receiving apparatus. A receiver list rearranging part (105) rearranges, in order of transmission capability, a receiver list where classified receiving apparatuses are listed in classes.

Patent number: 8031608Abstract: It is an object to provide a flow control method in which a packet round trip time is not excessively calculated out and its performance is not unnecessarily deteriorated even at the time of continuously connected packet transfers through relays of a plurality of receiving terminal devices. This method is directed to a flow control method in which the delivery of packets are carried out through relays of a plurality of receiving terminal devices. The method is comprised of steps (S501-S517) for acquiring a packet round trip time for every pair of neighboring terminal devices in a path of the delivery, a selection step for selecting one from the acquired round trip time in accordance with a predetermined standard, and a step (S518) for calculating a packet transmission rate on the basis of the selected round trip time, so that the round trip time of each receiving terminal device is measured and the transmission rate is calculated in accordance with the measured result.Type: GrantFiled: August 29, 2007Date of Patent: October 4, 2011Assignee: Panasonic CorporationInventors: Eiichi Muramoto, Takahiro Yoneda, Kazunobu Konishi

Patent number: 8023509Abstract: A multicast communication system in which a receiving node which has detected a packet loss can make a retransmission request without applying a high load to a transmitting node, all receiving nodes, and the band of the entire network. The transmitting node transmits an explicit multicast data packet including an address list including a plurality of destination addresses and a bitmap indicating whether the data packet has been delivered to the respective destination addresses, to a plurality of the receiving nodes. The receiving node which has detected the packet loss checks an address list and bitmap of another data packet received and selects a receiving node to which the another data packet has been delivered as a retransmission requester. The receiving node which has detected the packet loss creates a unicast retransmission request packet with the selected receiving node as the destination and transmits it to the selected receiving node.Type: GrantFiled: May 17, 2007Date of Patent: September 20, 2011Assignee: Panasonic CorporationInventors: Kazunobu Konishi, Eiichi Muramoto, Takahiro Yoneda

Patent number: 8009564Abstract: In a communication of explicit multicast system used in SICC, the frequency of variation of the transmission rate is reduced to achieve a multimedia data transmission exhibiting a high quality. An available bandwidth estimating part (102) of a transmitting apparatus (100) uses feedback information, which is received by a receiving part (101) from a receiving apparatus (200), to estimate a bandwidth available to the receiving apparatus. A bandwidth correcting part (103) corrects, based on a difference in header size between a current class and an upper-order class, the estimated available bandwidth. A class deciding part (104) uses the corrected bandwidth to change the class to which the receiving apparatus belongs.Type: GrantFiled: August 1, 2006Date of Patent: August 30, 2011Assignee: Panasonic CorporationInventors: Kazunobu Konishi, Eiichi Muramoto, Takahiro Yoneda

Patent number: 7898998Abstract: Provided is a multicast distribution device for transmitting a packet in which a reception node can easily perform signal synchronization between a plurality of hierarchized data. The multicast distribution device (100) includes an input unit (110), a hierarchy encoding unit (112), a communication control unit (114), a flow rate control unit (116), a reception node sorting unit (118), a hierarchy setting unit (120), a hierarchy information storage unit (122), and a reception node information storage unit (124). The reception node sorting unit (118) decides the order of addresses described in an address list of a packet of each hierarchy in the descending order from the most significant hierarchy to the least significant hierarchy. When deciding the address order for an arbitrary hierarchy, the address order decided in the more significant hierarchy by one step is acquired as it is and after this, the address order of the remaining reception node is decided.Type: GrantFiled: February 13, 2007Date of Patent: March 1, 2011Assignee: Panasonic CorporationInventors: Takahiro Yoneda, Kazunobu Konishi, Eiichi Muramoto
