Abstract:
An embodiment takes the form of a process that includes transmitting video frames to a receiving device during a first transmission period of one or more time slots of a half-duplex air interface, and receiving feedback messaging from the receiving device during a feedback period of one or more time slots of the half-duplex air interface. The process further includes suspending, after the first transmission period, transmission of video frames for a suspension period of one or more time slots of the half-duplex air interface, and after the feedback period and after the suspension period, transmitting one or more recovery frames to the receiving device during a recovery period of one or more time slots of the half-duplex air interface. The one or more recovery frames collectively include inter-coded macroblock data and/or intra-coded macroblock data.
