PY2UBK — Broadcast standardization engineering

What I work on

Cloud and hybrid signal chains

Moving playout, packaging and transport onto cloud infrastructure without breaking the timing the air chain depends on — and being honest about which functions have to stay at the site.
Transport-layer conformance testing

Specification-derived test suites for ATSC 3.0 and TV 3.0 transport — STLTP, ROUTE/DASH, MMTP. Explicit pass/fail criteria and campaigns that reproduce.
Studio-to-transmitter links over IP

Carrying STLTP across public networks and CDNs instead of dedicated circuits: latency budgets, buffer sizing, byte-integrity verification, and how the link behaves when it degrades.
SFN timing and emission synchronization

Absolute-time emission under A/324, GNSS-disciplined references, and diagnosis of the conditions that actually make exciters drop lock.
Impairment and resilience campaigns

Reproducible burst-loss and jitter models run against real modulators, measured from the probe side rather than inferred from the sender.
Coverage prediction and link planning

Terrain-profile, diffraction and Fresnel-based coverage studies; link budgets computed against licensed-facility records rather than nominal figures.
Specifications and technical reporting

Turning measurement into documents that survive review: test plans, conformance reports, and standards contributions.

Fifteen years in broadcast and media engineering Playout, master control and SMPTE 2110 IP video routing designed and commissioned with broadcasters across Latin America.
Cloud architecture for media and video transport Current day-to-day work: designing broadcast and contribution systems on public cloud infrastructure, at specialist level.
Transport layer of Brazil's TV 3.0 Research team member on the reference transport multiplexer and demultiplexer for Phase 3 of the national programme, and continuing work on the transport-layer test suite.
Measurement on operating transmitter sites Modulators, exciters, GNSS references and spectrum probes on live towers, not only on the bench.
