· IPTV with Lime for ITU
ITU(International Telecommunications Union)はIPTVの標準化を努めてきています。ITUがITU-T H.721 において高品質なIPネットワークの上でのマルチメディアサービスとしてIPTVを定義しています。独自なIPTV規格を持っていない国がITU-T IPTV規格に大きな関心を持っています。一部国が実証実験を実施しています。弊社がITU-Tサポートしている実証実験に参加し、社会貢献の一つを取り込んでいます。また、弊社のIPTV with Lime for ITUソリューションはサーバー側と連携し、ITU TU-T H.721コンプライアンステストに合格しています。
