Abstract:
The H.264/AVC video encoding standard has many advanced features that can be tailored to suit a wide range of applications. In order to obtain optimal coding performance in video sensor networks (VSNs), it is essential to find the right setting parameters for the encoder. There is a trade-off between required energy for encoding and transmission of video content in VSNs that can be exploited to minimize total power consumption. In this study, we model the complexity and bitrate in H.264/AVC codec. By using the model, the trade-off between encoding and transmission energy consumption is further exploited. Our experiments show that the complexity modeling error is less than or equal to 3.45%. However, the bitrate modeling error that we obtain is less than or equal to 11.6%.
