Techniques are provided for video communication between multiple devices. Each of a plurality of video packets is designated as being part of a required reference frame that is subsequently to be used for a repair process. A stream of video packets that includes the packets for the required reference frame is transmitted from a source device over a communication medium for reception by a plurality of destination devices. A determination is made that at least one of the plurality of destination devices did not receive at least one packet of the required reference frame, and the at least one packet is retransmitted the at least one of the plurality of destination devices. When the retransmitted packet is received at the at least one destination device, it is decoded and stored without using it for generating a picture for display at the time that the at least one packet is received.
