Efficient and Self-Optimizing Multi-Source Media Streaming Using CMMF
Coded Multi-Source Media Format (CMMF) is an extensible container format designed to facilitate the management and interchange of audiovisual media and metadata. It enables efficient, decentralized, multi-source, multi-path, and multi-access content delivery for services that require high quality, availability, and robustness while also having strict latency and bandwidth requirements. It is protocol-agnostic and can be easily incorporated into existing systems and workflows. Results from extensive, real-world testing on a commercial content distribution platform show that CMMF-enabled multi-source delivery significantly improves client Quality of Experience (QoE) across all relevant Key Performance Indicators (KPls) compared to a widely adopted platform that switches between multiple content distribution networks (CDNs). 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.
