A technique that is becoming increasingly popular is to use a mobile television camera and microwave links to convey the picture and sound back to the control point. The limited number of microwave channels available for this purpose can be supplemented with optical links over unobstructed paths of a kilometer or less. FCC authorization is not required but the light beams must be safe in the environment.", "abstract$meta": { "confidence": "high", "note": "Backfilled from SMPTE canonical repository (smpte-canonical-audit/canonicalLibrary.*.json)", "originalValue": null, "source": "parsed", "updated": "2026-07-08T00:35:38.133Z", "version": "smpte-canonical-repo@v1" }, "authors": [ { "affiliation": "CBS Technology Center, Stamford, Connecticut", "bio": "Abraham Albert Goldberg is Associate Director, Television Research, at the CBS Technology Center in Stamford, Conn.
