ARQ in various forms is an important defence against RF error bursts but needs to be adaptive when delay sensitive encoded video is transmitted. It is demonstrated that adaptive ARQ itself is sensitive to mobile device buffer size and should be combined with an active discard policy based on picture type. For some Bluetooth send buffer sizes, this leads to up to 10 dB improvement in delivered video quality over adaptive ARQ alone.
