Awarded the special prize of broadcasting technologyof the 40th Hoso Bunka Foundation Award
Presentation ceremony of the 40th Hoso Bunka Foundation (HBF* ∗) Award was held inTokyo on 25 June 2014. The "Loudness Implementation Project" formed by Commercial
Broadcasting Federation, NHK and ARIB, received the special prize of broadcasting
technology in individual and group divisions.
The HBF award is presented annually from the HBF to the excellent broadcast program,broadcast technologies achieved past one year.
The "Loudness Implementation Project" has worked to introduce loudness management
into TV broadcasters in Japan. The project has been highly evaluated, and Mr. Eiichi
Matsunaga who is a member of this project in ARIB, represented to receive the prize.
The loudness management eliminates the difference in audio level that would occur
between TV programs or TV channels, and has been introduced to all television
broadcasters in Japan by April 2013, which has been welcomed by audience.

∗HBF : An independent non-profit organization which was established in February 1974
and aims to promote the culture and technological development of broadcasting.

The 18th GSC Meeting
The 18th meeting of the Global Standards Collaboration (GSC), a senior-level gatheringof the world’s leading information and communication technologies (ICT) standards
organizations, took place on 22 to 23 July 2014, hosted by ETSI (EuropeanTelecommunications Standards Institute) in Sophia Antipolis, France.
GSC-18 meeting focused on three topics which would require strategic discussing todevelop standards and to bring benefits to industries. Three topics were Machine toMachine (M2M) / Internet of Things (IoT), Software Defined Networking (SDN) / Network
Functions Virtualization (NFV), and Critical Communications.
GSC welcomed two new members at this meeting: the IEEE Standards Association(IEEE-SA) and TSDSI (Telecommunications Standards Development Society, India). Withthese new members, GSC members counts to 11.
Press release was issued on 28 July 2014.
