Over-the-top (OTT) streaming video is the fastest growing form of video consumption, overtaking traditional linear TV and disk-based playback. As carriers and programmers embrace OTT delivery, many find that quality of experience is a key differentiator. However, consistently delivering a high quality viewing experience via bandwidth-constrained networks continues to pose significant challenges. Long start-up time, buffering stalls, low quality video, and playback artifacts can all degrade quality of experience and shorten viewer engagement, directly impacting monetization.
Adaptive bitrate (ABR) streaming is the current industry standard for Internet video and for OTT services. ABR addresses buffering and stalling, enabling continuous playback as the available bandwidth varies. However, while ABR addresses the varying bandwidth problem, it does not deliver consistent video quality.
This paper provides an overview of ABR streaming and outlines the challenges service providers face today. It then introduces QBRTM, a new ABR enhancement technology from MediaMelon, and shows the benefits it provides versus alternative approaches.
QBR is easily integrated into existing workflows without changing the video content and yields dramatic benefits. QBR enables service providers to enjoy the quality benefits of variable bitrate (VBR) encoding, ensuring consistent quality playback, while retaining the buffering/stalling reduction of traditional ABR streaming.
