A test broadcasting using the SHV HEVC codec is scheduled for 2016. HEVC is the newest video coding standard, and is capable of achieving approximately twice the level of compression of the existing AVC (Advanced Video Coding)/H.264 scheme. Its coding performance is expected to be particularly high for SHV videos, especially due to extended block partitioning. In this paper, we describe the fundamentals of HEVC and its suitability for high-resolution videos such as SHV. We also introduce the specifications of the developed SHV encoder and its approach to achieving real-time processing. Finally, the results of image quality evaluation are presented, which confirm that the newly developed encoder can achieve a higher image quality than a conventional SHV AVC encoder.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptem/10.5594_M001523.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "authors": [ { "affiliation": "NHK, 1-10-11, Kinuta, Setagaya-ku, Tokyo, Japan", "name": "Yasuko Sugito" }, { "affiliation": "NHK, 1-10-11, Kinuta, Setagaya-ku, Tokyo, Japan", "name": "Kazuhisa Iguchi" }, { "affiliation": "NHK, 1-10-11, Kinuta, Setagaya-ku, Tokyo, Japan", "name": "Atsuro Ichigaya" }, { "affiliation": "NHK, 1-10-11, Kinuta, Setagaya-ku, Tokyo, Japan", "name": "Kazuhiro Chida" }, { "affiliation": "NHK, 1-10-11, Kinuta, Setagaya-ku, Tokyo, Japan", "name": "Shinichi Sakaida" }, { "affiliation": "NHK, 1-10-11, Kinuta, Setagaya-ku, Tokyo, Japan", "name": "Yoshiaki Shishikui" }, { "affiliation": "Mitsubishi Electric Corporation, 5-1-1, Ofuna, Kamakura, Kanagawa, Japan", "name": "Hiroharu Sakate" }, { "affiliation": "Mitsubishi Electric Corporation, 5-1-1, Ofuna, Kamakura, Kanagawa, Japan", "name": "Takayuki Itsui" }, { "affiliation": "Mitsubishi Electric Corporation, 5-1-1, Ofuna, Kamakura, Kanagawa, Japan", "name": "Nobuaki Motoyama" }, { "affiliation": "Mitsubishi Electric Corporation, 5-1-1, Ofuna, Kamakura, Kanagawa, Japan", "name": "Shun-ichi Sekiguchi" } ], "authors$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/Source Bak/smptem/10.5594_M001523.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "year": "2013", "year$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptem/10.5594_M001523.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" } }, "copyright$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptem/10.5594_M001523.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docId": "10.5594-M001523", "docId$meta": { "confidence": "high", "note": "Derived from DOI 10.5594/M001523", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docLabel": "SMPTE Meetings and Conferences ( October 2013)", "docLabel$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": "Development of the Super Hi-Vision HEVC/H.265 Real-Time Encoder", "docTitle$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptem/10.5594_M001523.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docType": "Conference Paper", "docType$meta": { "confidence": "high", "note": "NLM
