The architecture: every piece explained
The top strip is capture + encoding. Camera capture. Color space. Transfer function. HDR standards.
The middle row is metadata + adaptation. Static metadata. Dynamic metadata. Tone mapping. SDR fallback.
The lower rows are ops. Delivery. QC. Ops — mastering + capacity + player check.

End-to-end flow
End-to-end: raw footage graded in BT.2020 PQ. HDR10 + Dolby Vision variants encoded. HLS manifest tags identify. Player picks best; device tone-maps per capability; SDR fallback used on older TVs. QC verifies no clipping.
