As a result of this research NHK has proposed an HDTV provisional standards featuring 1,125 scanning lines, 60 Hz field frequency and 5:3 aspect ratio. Items based on these standards, such as HDTV camera, display, telecine, VTR, etc., are currently under development. HDTV, which is capable of storing at least 5 times more information than a conventional TV and displaying a highly detailed wide screen image, is drawing public attention as the TV system of the next generation.", "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": "Sanyo Development Center", "bio": "Tateo Toyama received his B.E. degree in 1970 from Doshisya Univ., Kyoto, Japan.
