A personal area network (PAN) is a feature of an augmented reality system, transmitting modified video for real-time display. Low-delay communication of encoded video over a Bluetooth wireless PAN is achieved in favourable channel conditions by a combination of dynamic packetisation of video slices together with centralised and predictive rate control. The result is minimised packet delay (below 0.05 s) and high-quality 40 dB video, with packet loss limited to 4% from radio frequency noise. Where channel conditions result in error bursts, dynamic rate change is introduced to reduce the need for packet retransmission and improve power efficiency.
