Efficient and Self-Optimizing Multi-Source Media Streaming using CMMF

Abstract

Coded Multi-Source Media Format (CMMF) is an extensible container format designed to facilitate the management and interchange of audio-visual media and metadata. Its use enables efficient, decentralized multi-source, multi-path, and multi-access content delivery for services requiring high quality, availability, and robustness but also have strict latency and bandwidth requirements. It is protocol-agnostic and can be easily incorporated into existing systems and workflows. Results collected through extensive, real-world testing on a commercial content distribution platform show CMMF-enabled multi-source delivery significantly improves client QoE across all relevant KPIs when compared to a widely adopted multi-CDN switching platform. CMMF-enabled clients during this trial experienced up to a 46% reduction in the video startup time, 75% reduction in the connection-induced rebuffering ratio, 12.7% improvement in the content normalized average session playback bitrate, 86.3% reduction in the video startup failure rate, and 58.9% reduction in the video playback failure rate.
