Embedded multimedia systems with adaptive rate control for power efficient video streaming

Abstract

A system includes an image sensor and a sending controller. The image sensor to generate video data at a source bit rate. The sending controller is coupled to the image sensor to transmit communication data representative of the video data. The sending controller includes one or more processors coupled to memory. The memory includes instructions, which when executed by the sending controller causes the system to perform operations. The operations include determining a first bit rate to encode a first portion of the video data, the first bit rate being different than the source bit rate. The operations also include generating a first video packet representative of the first portion by encoding the first portion at the first bit rate. The first video packet is stored in a video packet buffer of the system. The operations further include determining, in response to generating the first video packet, whether to transmit the first video packet as the communication data with the sending controller based on at least one of a transmission rate threshold, a transmission interval threshold, or a buffer fill threshold.
