[Inter BEE 2014] Techno Mathematical - HEVC real-time decoding technology for 8K/60p debuted - Video under 200 Mbps bitrate played on an 8K display

■ High-speed processing with general-purpose hardware
　Techno Mathematical exhibited at Inter BEE 2014 and demonstrated 8K (7680 x 4320) 60p real-time HEVC video decoding technology. It achieves real-time decoding with software using standard hardware. With their proprietary Digital Media New Algorithm (DMNA), they achieve real time processing with just an Intel multi-core CPU. DMNA is an algorithm that uses mathematical methods such as factorization, folding operations, and hierarchical structure to dramatically reduce computation load.

■ Bitrate under 200 Mbps
　As a reference exhibit, a previously recorded HEVC Main 10 standard (10 bit, 4:2:0) 8K video sample was decoded in real time and played on a Sharp 8K display. The bit rate of the demonstrated video was undisclosed, but it was less than 200 Mbps. The company's codec supports B slice and uses a deblocking filter. It can also use 2pass for higher quality of offline processing when it is alright to spend more time on decoding.

■ 4K signage system also exhibited
　The company offers audio and video compression and decompression solutions based on DMNA and software/hardware IP systems. Their technology is loaded into a variety of digital devices, such as digital cameras, smartphones, video conferencing systems, and low-latency transmission systems.
　In addition to 8K decoding technology, there were exhibitions of ultra-delay, high-quality video transmission technologies at the booth. 4K/60p AVC encoding and decoding were processed by a 1RU appliance each. By combining multiple devices equipped with storage and a system capable of UDP transmission with ultra-delay, they developed a system capable of large-screen high-definition 4K multi-display simultaneous display signage.

■ Demonstration of low-bitrate ultra-delay transmission with proprietary encoding
　Employing a high-compression original codec, they demonstrated a new product capable of low bitrate, ultra delay transmission. The transmission delay is 0.1 seconds. The transmission rate is from 128 kbps to 3 Mbps. At 18" x 5" and weighing 1.5 kg, the system is even smaller and lighter than the current model. The encoder and decoder module set can be used for monitoring and life sciences in addition to transmission of live events from on-site. The price is about ￥1 million. Mass production sales are planned for January 2015.
