TECHNICAL COMMITTEE MEETING Special Topic Session FUTURE BROADCAST TECHNOLOGIES
The Special Topic Session was held at the NHK Science & Technology Research Laboratories in Tokyo. The session was moderated by Dr Kazuyoshi Shogen, TC Chairman and Executive Research Engineer at the NHK-STRL, who introduced the two speakers. They were to look at interesting broadcast developments being researched at the laboratories.
web, to provide the rich and enhanced experience viewers were looking for. The HybridCast system took advantage of the core strengths in broadcasting, such as reliable high quality content, and communication which brought the capability for interactivity and personalisation. The new platform enhanced broadcast services, providing a more personalised and focused experience.
Special Topic Session
Dr Hisakazu Katoh, Head of Advanced Broadcasting Platforms Research Division of NHK-STRL, presented the topic – Towards the Construction of HybridCast: Fusing Broadcasting and Communications. He looked at the development of digital services and how it gave rise to IP based contributions. This had led to the launch of NHK on-demand in 2008 to be followed later by the NHK World iPhone App. Describing the current status of convergence he introduced the concept of HybridCast, as a new platform in the 3 screen era. He stressed the importance of harmonising and presenting the content, both broadcast and
On the topic – The Future of Television: Super Hi-Vision and Integral 3DTV, Dr Eisuke Nakasu, Head of Advanced Television Systems Research Division of NHK-STRL, presented the ongoing research activities on Super Hi-Vision (SHV) and 3DTV at the Laboratories. Explaining the SHV image, he stated that, with the recommended 0.75 screen height viewing distance, an image size of 7680x4320 lines and a 33 megapixel picture, the viewer will feel as though he is immersed in the world depicted on the screen. Adding that the 22.2 3D surround sound system, developed for SHV, adds more reality to that experience. He described the dual-green imaging device and the codec used for recording, noting that a full resolution compact camera with 33 megapixel CMOS capture device had been developed this year. Introducing the Integral 3DTV system and the concept of integral imaging using the GRIN micro- lens array, he explained how this technology can provide a natural viewing experience without glasses. It is totally different from the current 3DTV technologies and provides full parallax viewing in both horizontal and vertical directions whilst being more feasible for broadcasting.
New Initiatives Identifies Action
The CTO Forum provided a platform for exchange of information among the ABU members on pivotal issues, primary solutions to the issues and information on how ABU could provide assistance on these issues.
The CTO Forum session was moderated by John Bigeni of DVB.
Kenji Nagai, NHK, emphasised that the Emergency Warning Broadcasting System (EWBS) and the ABU Radio-in-a-Box (RiB) could play a major role in establishing quick communication between the authorities and affected populations.
Yeo Kim Pow, Medicorp, expressed his concerns regarding the impact on broadcasters and consumers when technology standards move from one generation to another without forward compatibility.
Abu Bakar, RTM noted that the major issues faced by RTM were the capital investment that the migration to digital involves, the human resources and training in digital technology.
Tan Kwong Meng, TV3, expressed his concerns about the reduced life span of digital production facilities such as file based workflows and the return on investments to the broadcasters.
John Yip, RTHK, noted the high level of complexity involved in planning for digital broadcasting, resource planning and the vital issue of equivalent replacement of aging population of experienced engineers.
Frederico Rosario, TDM, described the developments in digital broadcasting in Macau, the challenges TDM faced and issues of using proprietary vs non-proprietary systems.
Phillip Nottle, Sony, identified the planning of spectrum for future usage and understanding digital based production systems by the programmers as primary concerns for broadcasters.
Mike McCluskey, ABC highlighted major issues such as the elements of multi-platform environments and the transformation of broadcasting, together with the need for programme makers to be educated prior to acquiring digital based equipment/systems.
