# Broadcast Creative

> Canonical hosted video and audio contracts for linear television and radio.

Linear television uses `video_hosted`; radio uses `audio_hosted`. Spot duration, codec, loudness, frame rate, and delivery-file constraints narrow the canonical. Network, station, daypart, rotation, clearance, and audience measurement remain media-buy facts.

Broadcast systems generally do not fire web trackers. Reconciliation uses traffic logs, affidavits, and audience currencies declared on the product/package. Each cut should carry its own traffic identifier.
