Here, we evaluate the transmission equipment cost of the proposed method based on a simple assumed distribution network. We predict that the cost can be decreased to 11–36% of that of conventional sub-carrier multiplexing (SCM) and FM conversion transmission methods. By analysing the dominant factors affecting the cost, we show that significant savings are achieved due to the fact that an optical signal can be received at a lower power using the proposed method than for signals transmitted using conventional methods.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/ORIGINAL SAMPLES/Conferences/smptem_2012_10/10.5594_M001476.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "authors": [ { "affiliation": "NHK Matsuyama Broadcasting Station, 5 Hori-no-uchi, Matsuyama city, Ehime pref., Japan", "name": "Takeshi Kusakabe" }, { "affiliation": "NHK Sendai Broadcasting Station, 1-11-1, Nishiki-cho, Aoba-ku, Sendai city, Miyagi pref., Japan", "name": "Takuya Kurakake" }, { "affiliation": "NHK Science and Technology Research Labs., 1-10-11, Kinuta, Setagaya-ku, Tokyo, Japan", "name": "Kimiyuki Oyamada" }, { "affiliation": "Ehime University, 3, bunkyo-cho, Matsuyama city, Ehime pref., Japan", "name": "Yoshihiro Fujita" } ], "authors$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_2012_10/10.5594_M001476.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "year": "2012", "year$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/ORIGINAL SAMPLES/Conferences/smptem_2012_10/10.5594_M001476.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" } }, "copyright$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/ORIGINAL SAMPLES/Conferences/smptem_2012_10/10.5594_M001476.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docId": "10.5594-M001476", "docId$meta": { "confidence": "high", "note": "Derived from DOI 10.5594/M001476", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docLabel": "SMPTE Meetings and Conferences ( October 2012)", "docLabel$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": "A Study of the Optical Distribution Costs of Multichannel Baseband Digital Broadcasts over a FTTH Network", "docTitle$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/ORIGINAL SAMPLES/Conferences/smptem_2012_10/10.5594_M001476.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docType": "Conference Paper", "docType$meta": { "confidence": "high", "note": "NLM
