Abstract :
This work proposes a complexity-control algorithm that efficiently utilizes encoding tools of an H.264 video coding system under different power status. Experiments performed on a power-scalable embedded system reveal the excellent rate-distortion performance with various power constraints. Specifically, the power consumption can be adjusted around 77% to 100% with PSNR degradation within 1.08 dB at the same bit rate.
