AV Device Queries: Difference between revisions

Latest revision as of 21:21, 19 February 2026

This page showcases advanced queries powered by Semantic MediaWiki (SMW). Every AV device in the wiki stores its specs — brand, device type, format family, inputs, outputs, and more — as structured semantic properties. That means we can ask the wiki surprisingly specific questions and get live, always-up-to-date answers.

These queries run against real data in the wiki, so as new devices are added and existing ones are updated, the results here update automatically.

Want to learn more about writing your own queries? See the SMW inline queries documentation.

Running your own queries

You can play around with SMW queries using the built-in query interface at Special:Ask, or try copying the below example queries to your sandbox.

Example Queries

Frame synchronizers with DUB input

Which devices have frame synchronization capability and a Hirose 7-pin DUB connector carrying Y/C color-under signal? These are the units that can frame-sync directly from a U-Matic or other DUB-output VTR without needing a separate adapter or transcoder.
