Ecosystems: PToB Architecture, Compatibility Boundaries, and a Validation Programme\n\nResearch draft  22 October 2026  16 pages · PDF\n\nCould several media ecosystems share a time base through

edition](https://ptob.dev/research/bluetooth-timecode-ecosystems/#citation)\n\n## Overview\n\nThis architecture study proposes a common time, quality and event contract beneath native app timestamps, vendor-specific Bluetooth interfaces and optional LTC/MTC outputs. It retains exact rational frame/sample mapping and the differences between control, jam and physical capture.\n\n## What this paper covers\n\n- Separate shared Bluetooth transport from actual vendor interoperability.\n- Map continuous time into exact frame and sample coordinates.\n- Define independent recorded-event checks for each adapter and output.\n\n## Research scope\n\nNo adapter, vendor integration, LTC/MTC generator or new hardware experiment is reported. Commercial interoperability, TAI firmware support, recorded-event accuracy and genlock remain unqualified.\n\n## Read it in context\n\nUse this as a media integration research plan. The timing measurements elsewhere concern their named clock references; they do not measure a camera exposure, audio sample clock or timecode input.\n\n[LaTeX source and references](https://github.com/yantisj2/PToB/blob/main/papers/ptob-bluetooth-timecode-preprint.tex)[Research methods and limits](https://ptob.dev/research/#methods)\n\n## Cite this edition\n\nJonathan Yantis.
