Samsung: UD tech, 3D content make future TV

What will the TV of the future look like?

Try an "immersive digital cinema" system with ultrahigh-definition (UD) technology and 3D user-generated content, said Hyung Kyu Lim, head of Samsung Advanced Institute of Technology, the R&D arm of the South Korean electronics giant.

Powered by the Internet, next-generation TV will require a large-screen display of 80 inches or more. It will have 4,096 x 2,160 resolution at a frame rate of at least 60fps, he said during a keynote address at this week's International Solid-State Circuits Conference (ISSCC).

Digital content with such a display at 24fps "requires around 300Mbit/s for transmission when compressed using JPEG2000 adopted by DCI," he said in a paper. "Assuming an effective bandwidth allocated per household at around 100Mbit/s using 1Gbit/s Fiber-to-the-Home (FTTH), it is apparent that a new innovative compression technology with three times more efficiency will be required."

The display itself must also undergo vast changes. As the UD "display has four times more pixels than HD display provides, new electrode materials are necessary for high-speed driving of pixels, and to overcome the reduced aperture ratio," he said.

One technology, 3D content, will be an enabler. "With increasing complexity of photorealistic 3D-graphics rendering for virtual reality and UD-display processing in [next-generation] TV, the amount of computing power required tends to increase by two to four times," he said.

"For example, UD-display processing at 60fps requires computing power on the order of 2,400 GOPS," he said. "Such a level of computing power is not expected to be available before 2015, with typical ASIC design without specialized hardware."

A more viable solution is a multicore processor, which could meet the requirement for UD-display at 60fps in the 2012 timeframe, he added.
