Why Videospan Uses CMAF for Scalable Video Delivery
How CMAF lets Videospan run a unified HLS and DASH delivery pipeline with lower storage cost, cleaner DRM operations, and faster playback adaptation.
How CMAF Works: The Common Media Application Format Explained
A practical technical breakdown of CMAF, the segmented media format that lets HLS and DASH share files while improving cache efficiency, DRM workflows, and low-latency delivery.
How MPEG-DASH Works: A Technical Guide to Dynamic Adaptive Streaming
A practical explanation of MPEG-DASH, from MPD manifests and segment addressing to codec flexibility, DRM, live streaming, and how it compares with HLS.
How HLS Works: A Technical Guide to Apple's HTTP Live Streaming
A practical guide to HLS, from master playlists and media segments to adaptive bitrate switching, live playback, Low-Latency HLS, DRM, and CMAF support.
Why a 4K Encoding Ladder Requires AV1 and HEVC Support
How to structure a practical 4K adaptive bitrate ladder across AV1, HEVC, and H.264 so viewers get the best stream their device and network can sustain.
Understanding Encoding Ladders: How Adaptive Video Quality Really Works
A practical guide to encoding ladders, the bitrate, resolution, and codec profiles that let streaming video adapt across real networks and devices.
Why AV1 and HEVC Are Required for 4K Video
Why practical 4K delivery depends on modern codecs, and how HEVC and AV1 reduce bitrate enough to make ultra-high-resolution streaming viable at scale.
