OKI Achieves H.265 Compatibility for OKI MediaServer and Succeeds in 4K Video Distribution

Plans early commercial introduction in line with standardization body recommendations

TOKYO, November 13, 2013 -- OKI has demonstrated the successful distribution of 4K(*1) video content offering four times the resolution of current high-definition TV through its OKI MediaServer video distribution server, a product already in wide use for commercial IPTV services and undergoing trials in international institutions. OKI MediaServer is currently used for large-scale IPTV services and at ITU IPTV IPv6 Global Testbed(*2) a video distribution test facility based on the ITU-T(*3) IPTV standards(*4). In trials, OKI has achieved compatibility with the new H.265/HEVC video codecs(*5) and successfully demonstrated 4K video distribution.

Also known as HEVC (High Efficiency Video Coding), H.265 is a new video codec standard recommended in January 2013 by the ITU. Offering a compression ratio double that of the current H.264(*6), H.265 is slated to enter use as the codec for 4K broadcasts in Japan in fiscal 2014. The standard is a leading candidate for future application to IPTV and cable video distribution.

OKI has developed H.265 support for its OKI MediaServer video distribution server in anticipation of widespread H.265 rollout for video distribution services, with successful 4K video distribution trials in laboratory environments. OKI has confirmed that video can be viewed on a 4K-compatible television after connecting a PC to the distribution server via in-house networks. Primary IPTV services consist of VOD(*7) and linear TV(*8); the latest trials verified linear TV services. VOD trials are also scheduled following the development of compatible terminals.

"Following these trials, OKI will work hard to submit proposals to various standardization bodies in the near future and to develop commercial products complying with the standards. ITU is already in the process of preparing documentation on recommendations for IPTV H.265 compatibility, a process to which OKI has contributed various suggestions," says Hidetoshi Saigou, Senior Vice President and General Manager, Telecom Systems Business Division at OKI. "OKI is also considering trials using the ITU IPTV IPv6 Global Testbed to expand into countries and regions that have adopted IPTV and are considering further resolution upgrades, including 4K video distribution."

OKI will continue to strive to promote expanded features and the standardization of these features to meet various market needs, including video services related to the 2020 Tokyo Olympics/Paralympic. OKI will thereby continue developing its video distribution platform business to heighten their appeal to service providers in Japan and elsewhere around the world.

  • *1 :4K

    A next-generation television format with a resolution of 3840 x 2160 pixels, or four times the resolution of current HDTV; also known as ultra high definition. Commercial 4K broadcasts are scheduled to begin in July 2014 in Japan.

  • *2 :ITU IPTV IPv6 Global testbed(I3GT)

    This testbed has been in use since October 2012 to verify the following: (1) whether a network offers bandwidth and quality (delay, loss) for adequate IPTV video distribution; (2) functions that allow collaborative linking of videos, still images, and text in content created based on LIME standard specifications as well as applications; and (3) operations on terminals complying with ITU-T IPTV standards. The content created by the participants is scheduled to be registered on the OKI Media Server to allow such verification.
