Over-the-top (OTT) streaming is the fastest growing form of video consumption, overtaking traditional TV broadcast. As carriers and programmers embrace OTT delivery, many find that quality of experience is a key differentiator.
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, ABR has some limitations, such as it does not deliver consistent video quality and it consumes more bandwidth than necessary.
QBR, a new ABR enhancement technology shows the benefits it provides versus alternative approaches. QBR is easily integrated into existing video workflows for both live and on-demand streaming. QBR does not involve the complexity of a new codec or a new streaming format – it works with standard HLS, MPEG-DASH or Smooth Streaming formats as well as popular H.264 and HEVC codecs. It does not involve the cost or complexity of re-processing the video. QBR is a simple and highly impactful way to cut streaming costs and improve quality by enhancing the way that current ABR works.
