Bitrate Control and QoE-CBR is Better

Summary (The MPD) When distributing video under constrained conditions, the bitrate control technique used to encode the files can have a profound impact on the quality of experience (QoE). Specifically, under some conditions, CBR-encoded files deliver a superior QoE to files encoded using 200% constrained VBR, while also reducing the overall bandwidth delivered. For producers ...Read more

Choosing the Optimal Segment Duration

SummaryWhen choosing an HLS or DASH segment duration for VOD video, the nature of the server/player connection is critical. For persistent connections, a segment size of two-three seconds produces good quality and optimal system throughput. For non-persistent connections, a segment size of six seconds produces the best overall throughput. With live video, if latency is ...Read more
