Sumitomo Electric Industries, Ltd., announced that it has been selected by NTT Plala Inc., a major Internet and IPTV Service provider in Japan, to provide Android OS based Ultra High Definition (UHD) Set Top Box for its “4Kp60*1” Video-on-Demand (VOD) service.

The ST-4100 series utilizes the newest “System on Chip” (SoC) hardware from one of the world’s leading chip suppliers. When coupled with in-house developed middleware, “STB Core”, which supports IP video streaming and security technology, such as TTS, MPEG-Dash, Marlin, Play Ready DRM, DLNA, and DTCP-IP*7, the new Set Top Box offers an unparalleled viewing experience for the subscriber. This rich experience is made possible and enhanced by 4Kp60 content being sent over an IP broadband network and Wireless home network, with such video streams being decoded on a real-time basis and streaming of video content to smartphones and tablets using DLNA and DTCP-IP*8.

“NTT Plala is proud to contribute the world’s transition to Ultra High Definition Video Services by serving the interests of our customers and stakeholders in Japan,” said Katsumi Nagata, CTO of NTT Plala. “We are very pleased to begin the world’s first 4Kp60 VOD commercial service and, we look forward to working with Sumitomo Electric to make the new Smart Set Top Box an integral part of this new service.”

“As a leading supplier for Broadband access network equipment and Smart TV IP set-top boxes, we are very proud to provide our IP-STB to NTT Plala, which enables the world first UHD 4Kp60 commercial service on Android OS based Smart IP-STB,” said Hiroaki Nishimoto, General Manager of Video Products Business Department of Broad Networks Division at Sumitomo Electric Industries. “4K service of Hikari-TV will make use of the newest HEVC (ITU-T H.265) IP video content delivery, as well as DASH (Dynamic Adaptive Streaming over HTTP) over an IPv6 FTTH network. We believe 4Kp60 will be quickly adopted by Tier-1 carriers, MSOs and satellite broadcasters in the world, and our experience with NTT Plala will keep us in a leadership position for this emerging technology.” Sumitomo Electric is also working with other major carriers, MSOs and satellite broadcasters in the world to design and built 4K Set Top Boxes, and hopes to make similar announcements in the near future. Collaborating with its strategic customers and partners, Sumitomo Electric has pledged its strong effort to realize a world, in which people can enjoy rich 4Kp60 content anytime and anywhere. High levels of security and robustness will be accomplished through secure hardware/software architecture, solid security chain, DRM/CAS technologies, etc.
