Abstract:
An apparatus and method configure RTCP packets in a control feedback handling in multimedia sessions. The apparatus and method are configured to provide sending of any RTCP individual packet as a non-compound RTCP packet an order within a time interval. The apparatus and method are configured so that an excessive length of compound RTCP packets are handled by fragmenting each compound RTCP packet in smaller non-compound packets and sending it spaced over time. The apparatus and method guarantee RTCP non-compound packets to provide an equivalent functionality as the RTCP compound packets by providing the same information to the receiver, and the receiver does not lack any feedback information. The apparatus and method are also configured to use semi-compound RTCP packets, where at least two non-compound/individual RTCP packets (but less than all the non-compound/individual RTCP packets that would be sent as compound packet) are sent together as a semi-compound RTCP packet.
