Abstract
This invention relates to a protocol, an information processing system, an information processing method for use with the system, information processing apparatuses, information processing methods for use with the apparatuses, storage media, and programs for allowing two-way network status to be known. An RTCP packet analysis unitanalyzes an RTCP packet in a receiver report RR received through an RTCP portfrom a user terminal over a network. Based on an RTCP sequence number obtained from the analyzed RTCP packet, a packet loss detection unitcalculates a packet loss rate with respect to the user terminal on the network. An RTCP packet creation unitattaches the calculated packet loss rate to a sender report SR and transmits the sender report at predetermined time intervals to the user terminal over the network. This invention applies to system that offer streaming content transmissions and real-time data deliveries over the network.
