Resumo
Video communications have demanded higher computing
power and, therefore, higher energy expenditure. To
provide greener software-based video encoding solutions, we
studied a method to optimize the prediction stage of H.264/AVC
in the energy sense (E) and tested it with a software implementation.
Besides looking for the coding options to the best RDperformance,
the process is constrained to fit within a certain
energy budget by an RDE optimization. We measure E as the
real demanded electric energy for a given system. Our RDEoptimized
framework allows for software-based real-time video
compression constrained electrical consumption. We show results
of energy-constrained compression and in some cases one can
save as much as 35% of the energy with small impact on RD
performance.
