Welcome to the summer edition of ARIB SEASON that covers both telecommunication andbroadcasting related subject.

13th CJK IT Standards Meeting
CJK Meeting on Information and Telecommunication Standards started on June 2002
with an initiative of ARIB of Japan, CCSA of China, TTA of Korea, and the TTC of Japanto promote growth of the information and telecommunication fields with the aim topromote actively mutual cooperation among the standards development organization ofJapan, China and South Korea.
The 13th CJK IT Standards Meeting hosted by TTA was held from Tuesday, 15 April toThursday, 17 April 2014 at Paradise Hotel in Busan, Korea. The Meeting was attended by
102 participating delegates representing ARIB, CCSA, TTA and TTC. 15 delegates from

CJK HoD (Head of Delegation) Adhoc was established at the 12th CJK meeting to initiate
high-level discussion to explore ways to enhance standardization cooperation among
ARIB, CCSA, TTA and TTC, and discussed through the conference call. The result wasthat the meeting agreed a principle and procedure for CJK joint adoption of standards
among CJK SDOs and common adoption of international standards, after that it wasreflected to the amended MoU and signed by HoD of each SDO at the end of this meeting.
The 38th IMT (International Mobile Telecommunication) WG, the 5th WPT (WirelessPower Transmission/Transfer) WG and other WGs were held parallelly with the 13th
Plenary meeting.
The IMT WG had exchanged information and opinions in relation to correspondence forthe 19th ITU-R WP5D meeting held in Halifax, Canada. And establishment of VoLTE(Voice over LTE) Interworking Adhoc was approved.

The WPT WG had approved Technical Report-2, which will be input to the SG1 WP1A
ITU-R.
Next 14th CJK IT Standards Meeting will be held from Tuesday, 21 April to Thursday, 23
April 2015 in Sapporo, Japan, hosted by ARIB/TTC.
