TECHNICAL COMMITTEE MEETING
Future Broadcast Technologies at the NHK Laboratories – Members’ visit to NHK-STRL
Some 100 ABU delegates were invited to visit the NHK Science & Technology Research Laboratories in Tokyo to witness some foremost broadcast technological developments. NHK made two presentations, one on SHV (Super Hi-Vision) and Integral 3DTV and another on HybridCast. The delegates toured the demonstrations in small groups.
the Next Generation showed that ISDB-T can provide a capacity of 60Mbps on a 6MHz channel.
Other demonstrations that were on display included Integral 3DTV (experimental 3DTV without glasses), Ultra High Speed CCD capable of 1M frames per second, Ultra High Sensitivity Camera, ISDB-T 8MHz System, on-line dictionary of JSL (Japanese Sign Language) with high-quality CG animation, Live Closed-captioning using Speech Recognition, Haptic Technology for representing 3D objects including a Multi-finger Virtual Haptic System, Full Resolution SHV Camera with three 33M-pixel sensors, 58-inch Ultra-HD Plasma Display with 0.33 mm pixel pitch and Long-haul Fibre-optic Contribution Link for SHV transmission at 24 Gbps for a group of 16 HD- SDI signals.
The SHV theatre demonstration, with footages shot on the latest SHV cameras, was very impressive in terms of reality and quality. The 22.2 3D surround sound system provided a real feel of being in the screen depicted environment. The new SHV technology will definitely serve to further enhance viewers’ experience. The new HybridCast system demonstrated how it can help bridge between broadcasting and communications, providing a much richer experience with relevant content and interaction using multiple devices. It included enhanced services like programme customisation, social TV, program recommendation and multi-device linking.
The other eye-catching development on display was the trial showcasing of high capacity RF transmission technology using ISDB-T for the next generation DTTV broadcasting incorporating ultra multi-level OFDM and dual polarized MIMO technology. This successful trial of
The delegates expressed considerable interest in the wide range of new technologies which are to be implemented progressively, with ISDB-T now mature, SHV and HybridCast imminent and integral 3DTV probably in the distant future.
