Abstract: Current implementations of low-latency adaptive streaming over HTTP utilize a diversity of presentation formats, containers, origins, and caching behaviors. For efficient delivery, a common origin and a single set of cacheable media objects provide the highest performance and scalability across a delivery system. This article introduces a means of leveraging the Common Media Application Format (CMAF) as a standardized container format, combined with specific content encoding constraints and addressing mode constraints in low-latency HTTP Live Streaming (HLS) (LL-HLS) and low-latency Dynamic Adaptive Streaming over HTTP (DASH) (LL-DASH), to provide a cross-format solution that maximizes edge cache efficiency and minimizes origin storage costs and client request rate.
