Abstract
A device, system and method for intelligently dropping frames in a congested wireless network. Video frames from a video encoder may be received and queued in an ordered sequence of outgoing video frames in a transmission queue to be transmitted as data packets by a wireless communication circuit. When network congestion is detected, a relative contextual importance level of an incoming frame received from the video input channel may be compared relative to at least one frame in the transmission queue. The compared frame that has a lower relative contextual importance level may be dropped or omitted from the transmission queue, thereby transmitting data packets of the frames in the transmission queue without the dropped or omitted frames.
