About 28. Multimedia

Multimedia networking transports time-sensitive audio, video, and interactive content requiring special handling beyond best-effort data delivery due to human perception constraints. Compression codecs reduce bandwidth through spatial/temporal redundancy elimination and perceptual modeling, while streaming protocols like RTP/RTCP provide timestamping, sequencing, and quality feedback, and adaptive bitrate algorithms adjust quality dynamically based on measured network conditions to balance fidelity and continuity.

Quality of Experience metrics like MOS, buffering ratio, and startup delay quantify subjective satisfaction objectively, guiding CDN placement, transcoding ladder design, and QoS policy enforcement. Emerging immersive formats (VR/AR, volumetric video) demand ultra-low latency and high bandwidth, pushing innovations in edge computing, foveated rendering, and predictive prefetching, illustrating how multimedia continuously stretches network capabilities and drives infrastructure investment beyond traditional data workloads.
