Crate timed_metadata 

Timed-metadata / DPI signalling conversion core.

Translates SCTE-35 splice information to and from the carriages used in OTT delivery: HLS EXT-X-DATERANGE (RFC 8216 / draft-pantos-hls-rfc8216bis §4.4.5.1) and DASH emsg (SCTE 214-3, scheme urn:scte:scte35:2013:bin).

Conversions are lossless: the original splice_info_section bytes are carried verbatim (DATERANGE SCTE35-OUT hex, emsg message_data).

Pure functions live in convert; the stateful Timeline session adds a wall-clock TimeAnchor and 33-bit PTS wrap-unrolling.

Modules

anchor

Media-time ↔ wall-clock mapping for conversions that cross into UTC.

convert

Pure conversion functions (the foundation layer).

daterange

HLS EXT-X-DATERANGE model + (de)serialization.

error

Crate error type.

event

Canonical timed-metadata event (the hub of the hub-and-spoke model).

timeline

Stateful conversion session: holds the wall-clock anchor and unrolls 33-bit PTS wrap across a stream of events.

Constants

PTS_HZ

90 kHz — the SCTE-35 / MPEG-2 PTS clock.
