ABSTRACT:
The present invention relates to an information processing apparatus and method, and to a program that ensure connection between devices connected to transmission paths of various transmission speeds. A media IM client #1logs in to a media IM server14and executes a speed measurement process with a measurement server200to determine its uplink speed and downlink speed. A media IM client #2at the other communication party also logs in to the media IM server14and executes a speed measurement process with the measurement server200to determine its uplink speed and downlink speed. The media IM clients #1and #2exchange the determined speeds via the media IM server14, setting a set speed, and communicate with each other at the set speed. The present invention is applicable to a personal computer, a network-enabled CE device, and a commercial application server on the Internet.
