Abstract
A data transfer system allowing high-quality transfer of streaming data through a network having a relatively large delay variation in data delivery is disclosed. When transferring streaming data in packets from a server computer to a client computer through a repeater provided in the network, the repeater buffers a streaming packet for a set time period before forwarding it to the client computer. The set time period is determined so that a receiving time interval of packets at the client computer is substantially equal to a sending time interval of packets at the server computer.
Claims9
A computer system for transferring streaming data in packets from a first computer to a second computer through a network, comprising:
- a repeater provided in the network, the repeater comprising a buffering controller for buffering a received packet for a set time period before forwarding it so that a receiving time interval of packets at the second computer is substantially equal to a sending time interval of packets at the first computer, wherein the set time period is adjusted based on either of reception condition information of the second computer and time stamp information of received packets so as to absorb delay variations.
A method for transferring streaming data in packets from a first computer to a second computer through a network, comprising the steps of:
- the first computer sending a streaming packet to a repeater;
- the repeater buffering the streaming packet for a set time period before forwarding it to the second computer so that a receiving time interval of packets at the second computer is substantially equal to a sending time interval of packets at the first computer;
- and the second computer buffering the streaming packet received from the repeater before reproducing it, wherein the set time period is adjusted based on either of reception condition information of the second computer and time stamp information of received packets so as to absorb delay variations.
