Fuzzy logic control based adaptive media playout design approach for video streaming

Adaptive media playout (AMP) control, common receiver-based technique, is proposed to adjust the playout rate based on the bit-rate fluctuation of network channels to avoid playout interruptions. Most AMP techniques found in the literature adjust playout frame rate based on the buffer fullness or the buffer fullness variation. However, choosing an appropriate threshold to adjust a playout frame rate is challenging due to fluctuation in the channel's quality and its unpredictable video bitrate. In this research, a new AMP control, based on fuzzy logic control, is proposed as a solution to avoid video stream interruption and the challenge of choosing an appropriate threshold. The new Fuzzy Logic Adaptive Media Playout (FLAMP) control is designed based on buffer fullness and its variation. The FLAMP is expected to constrict the buffer outage probability and improve the video playback smoothness.
