Screen dynamics analysis-based adaptive frame skipping for efficient mobile screen sharing

Abstract

The introduction of ubiquitously connected mobile computing platforms acted as a catalyst for accessing and enjoying multimedia/visual contents on a more diverse set of computing environments than ever before. Recently, with the standardization of various protocols, a number of screen sharing services have been introduced, in which the contents of a mobile computing platform's screen is shared with a neighboring device [1]. With these services, data contents collected from various external sensing sources, can be captured at a mobile platform and (visually) shared easily with others using direct wireless connections. However, a previously unconsidered technical issue begins to impact the user experience levels of these multimedia/screen sharing mobile services. Specifically, we begin to notice energy efficiency as an important performance factor to consider when utilizing visual contents on mobile platforms with resource limitations. Actively using computational resources for visual applications lead to device heating and shorter battery life-times, as well as increased use of the wireless bandwidth when downloading or sharing the visual contents.
