Transmisión inalámbrica multimedia coordinada con DASH-SAND

Abstract

[EN] The adoption of DASH (Dynamic Adaptive Streaming over HTTP) as a video transmission standard has introduced new challenges in environments with high density of Wi-Fi clients. If video players do not take into account the playback status of other devices in the network unfair bandwidth distribution may cause playback problems (stalls, low playback quality, etc.). This paper proposes a collaborative playback technique based on DASH-SAND (MPEG¿s Server and Network Assisted DASH) that aims to reduce, in a collaborative way, the number of interruptions in the playback of multimedia content in Wi-Fi environments with high density of users. Results prove that the proposed solution reduces both the number and duration of stalls at the expense of decreasing the average representation of the playback.
