The development of wide-gamut displays and high-quality gamut mapping are major challenges in the workflow of UHDTV production today. While monochromatic light sources, such as lasers, are ideal for UHDTV wide-gamut displays, wide-gamut LCDs with non-monochromatic backlight sources, such as quantum dot LEDs, may well be used from the viewpoint of both cost and performance. Furthermore, a high-quality gamut mapping algorithm between UHDTV and HDTV for live broadcast production is essential. This paper offers solutions to these challenges.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/ORIGINAL SAMPLES/Conferences/smptem_2014_10/smptem_2014_10.xml/10.5594_M001555.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "authors": [ { "affiliation": "NHK, 1-10-11 Kinuta, Setagaya, Tokyo 157-8510, JAPAN, masaoka.k-gm@nhk.or.jp", "name": "Kenichiro Masaoka" }, { "affiliation": "NHK, 1-10-11 Kinuta, Setagaya, Tokyo 157-8510, JAPAN, yamashita.t-hq@nhk.or.jp", "name": "Takayuki Yamashita" }, { "affiliation": "NHK, 1-10-11 Kinuta, Setagaya, Tokyo 157-8510, JAPAN, iwasaki.y-iq@nhk.or.jp", "name": "Yukiko Iwasaki" }, { "affiliation": "NHK, 1-10-11 Kinuta, Setagaya, Tokyo 157-8510, JAPAN, nishida.y-fe@nhk.or.jp", "name": "Yukihiro Nishida" }, { "affiliation": "NHK, 1-10-11 Kinuta, Setagaya, Tokyo 157-8510, JAPAN, sugawara.m-fq@nhk.or.jp", "name": "Masayuki Sugawara" } ], "authors$meta": { "confidence": "high", "note": "Object form (schema 2.3.0) migrated from string form via migrateAuthorsToObjectForm.js; bio/affiliation backfilled from _source/SMPTE/HIGHWIRE/ NLM ++", "source": "parsed", "updated": "2026-06-23T00:04:25.562Z", "version": "authors-migrate-object-form@v1" }, "contentType": "orig-research", "contentType$meta": { "confidence": "high", "note": "Canonical-confirmed full paper (summary-abstract set is orig-research in the SMPTE canonical repos); HIGHWIRE-era abstract label was a delivery artifact", "originalValue": "summary-abstract", "source": "resolved", "updated": "2026-07-09T19:12:47.628Z", "version": "contenttype-fixes@v1" }, "copyright": { "holder": "Society of Motion Picture and Television Engineers, Inc.", "holder$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/ORIGINAL SAMPLES/Conferences/smptem_2014_10/smptem_2014_10.xml/10.5594_M001555.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "year": "2014", "year$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/ORIGINAL SAMPLES/Conferences/smptem_2014_10/smptem_2014_10.xml/10.5594_M001555.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" } }, "copyright$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/ORIGINAL SAMPLES/Conferences/smptem_2014_10/smptem_2014_10.xml/10.5594_M001555.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docId": "10.5594-M001555", "docId$meta": { "confidence": "high", "note": "Derived from DOI 10.5594/M001555", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docLabel": "SMPTE Meetings and Conferences ( October 2014)", "docLabel$meta": { "confidence": "medium", "note": "Composed from venue title, volume/issue and date", "source": "inferred", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docTitle": "Color Management for Wide-Color-Gamut UHDTV Production", "docTitle$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/ORIGINAL SAMPLES/Conferences/smptem_2014_10/smptem_2014_10.xml/10.5594_M001555.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docType": "Conference Paper", "docType$meta": { "confidence": "high", "note": "NLM
