Basic Playout

The Fabric’s native just-in-time audio/video pipeline in the core protocol creates and serves the playout manifest and playable streaming segments in its software dynamically (and on any node) such that any specific manifest capabilities can be readily added to the pipeline. The approach is also component based so different variants can be generated on demand. The current production AV pipeline supports creation of standard DASH/HLS CMAF-packaged ABR manifests (fMP4, 1 frame per fragment) and playable segments (2 seconds) with the following playout features:

• Live, Delayed Live, VOD Playout
• Low Latency Live - 2 seconds “live edge” pullback globally
• Any resolution - 100 Mbps Visually Lossless, 8K, 4K with dynamic ABR
• HDR10
• Subtitles/captions
• Multiple audio tracks
• Live Multiview Switch for personalized views
• Forensic watermarking using NAGRA A/B
• DRM (Apple Fairplay, Google Widevine), and Clear Key
• Content Encryption (CBCS and CENC)
• Discontinuities for inserted content / play across content boundaries, e.g. ad insertion
• Dynamic Content Selector for personalized insertion of content
• SCTE cues read, stored, and transmitted - can be added as needed to the output manifest
• Automatic Content Verification through Fabric Hashes
