Abstract: A method and apparatus for conferencing dynamically determines conference parameters such as image layout, image resolution and bandwidth. The conference parameters are dynamically determined based on the number of participants or video sources or both that currently connect to the conference. Video signals received from connected sites are processed to provide a composite video signal according to defined conference parameters and the composite video signal is transmitted to the connected sites. Upon one or more other sites connecting to the conference or one or more of the connected sites disconnecting from the conference or both, such that the number of sites or sources currently connected in the conference changes, one or more conference parameters is redefined. The received video signals are processed according to the redefined conference parameters to provide a second composite video signal that is transmitted to the connected sites.

Abstract: A method and a gateway provide for down speeding the data rate at the circuit switched side of a call being translated in the gateway if the packet switched side does not have sufficient bandwidth capabilities for matching the circuit switched data rate. The gateway compares the bandwidth of the circuit switched and packet switched sides of a call after establishing the connection. If the packet switched side of the call is connected at a lower rate than the circuit switched side, e.g., because of insufficient capabilities of the packet switched endpoint, the gateway initiates a down speeding procedure at the circuit switched side. The down speeding procedure disconnects a number of B-channels of the circuit switched connection to make the call rate equal or lower than the call rate of the packet switched side of the call.
