摘要： An adaptive control method in real-time communication for taking measures against the conditions of the loss of a receiver report packet which is sent out from an apparatus at the side of receiving distributed data toward a distribution server, thereby achieving an appropriate data distribution adaptive to transmission path conditions and/or communication conditions: According to the method, a dynamic arrangement for the transmission interval of a receiver report packet is made between data distribution server (301) and data reception apparatus (101) Then, after starting the transmission/reception of real-time data, data distribution server (301) monitors the reception conditions of the receiver report packet in a unit of the arranged transmission interval, and then adaptively controls a data transmission rate, etc., based on a monitoring result.

摘要： A packet compressor 12 operates under a reliable mode or an optimistic mode. A mode determination unit 31 counts the number of ACK packets or NACK packets received by a unit time X by an ACK/NACK packet receiver 14. When the counted number of NACK packets is larger than a predetermined value Y, the mode determination unit 31 switches the operation mode of the packet compressor 12 to the reliable mode. When the counted number of ACK packets is larger than a predetermined value Z, the mode determination unit 31 switches the operation mode of the packet compressor 12 to the optimistic mode.
