Abstract EN
Scalable video coding allows an efficient provision of video services at different quality levels with different energy demands.
According to the specific type of service and network scenario, end users and/or operators may decide to choose among different energy versus quality combinations.
In order to deal with the resulting trade-off, in this paper we analyze the number of video layers that are worth to be received taking into account the energy constraints.
A single-objective optimization is proposed based on dynamically selecting the number of layers, which is able to minimize the energy consumption with the constraint of a minimal quality threshold to be reached.
However, this approach cannot reflect the fact that the same increment of energy consumption may result in different increments of visual quality.
Thus, a multiobjective optimization is proposed and a utility function is defined in order to weight the energy consumption and the visual quality criteria.
Finally, since the optimization solving mechanism is computationally expensive to be implemented in mobile devices, a heuristic algorithm is proposed.
This way, significant energy consumption reduction will be achieved while keeping reasonable quality levels.
