Embodiments described herein relate to the adaptation of a real-time Web communication transmission profile, particularly the adaptation of throughput such as the video throughput of the real-time Web communication. A method is described for adapting a real-time Web communication transmission profile, including changing a transmission profile parameter of a real-time Web communication device on the basis of bandwidth-related data recovered during a real-time Web communication time period. Thus, the transmission profile can be adapted to the bandwidth of the real-time Web communication in progress, allowing a user to enjoy the best quality when the bandwidth allows and, conversely, to limit transmission errors when the bandwidth does not allow high throughput.
