Introduction: Optimizing Content Delivery

Welcome SMPTE readers to our final technical paper issue of the 2024 season. We are wrapping this year up with a mixed issue. Most of our technical papers will cover improvements and proposals for ultra-low latency encoding and live-streaming applications. Our two off-topic papers on this issue will cover new HDR/SDR dynamic conversion methods with metadata and in-camera visual effects improvements utilizing SMPTE ST 2110. Here's a brief snippet for each of the papers you'll find in this issue: “Live Sports Streaming with Prioritized Media Over-QUIC Transport:” This paper explores the innovations in streaming prioritization. The authors present experimental results on latency for frame-type-based (I-frame, B-frame, P-frame) prioritization and show how the same on-time display ratio can be achieved with lower latency budgets if we apply a better prioritization scheme.
