NTT has developed a new MPEG HEVC/H.265 codec for real-time or live compression of 4K video signals at 100 and 120 frames per second, so called High Frame Rates. The company also introduced an 1 Rack Unit high encoder, and a same size decoder.
High Frame Rate capturing and display makes for smoother and sharper portrail of motion.
NTT intends to enhance the quality of sports broadcasts, Virtual Reality and surveillance applications.
In March 2015, NTT announced a real–time 4K/60p HEVC video encoder LSI (NARA) and have contributed to the rapid acceptance of UHD service.
Since live sports programs are the main drivers of UHD service, HFR video technologies, which are especially beneficial for sports content, have attracted strong interest from UHD service providers.<\q>
The 4K HFR HEVC encoder appliance provides backward compatibility by supporting temporal–scalable encoding, meaning the output stream can be decoded by conventional SFR (Standard Frame Rate) decoder to yield 4K SFR video.
The codec supports the MPEG Media Transport (MMT) protocol which enables hierarchical transmission. This way two independent transmission routes can be used to transfer the base–layer data, which is used for decoding of 4K SFR video, and the enhancement–layer data, which is used together with base–layer data for decoding 4K HFR video.
MMT protocol enables the base–layer data and enhancement–layer data to be transmitted over different IP streams. Using two different transmission routes creates timing offset in the arrival of the data streams. MMT can reconfigure the order of data by using timestamps based on UTC (coordinated universal time).
By using two “NARA” chips, NTT's HEVC compression/decompression chip, in parallel, the encoder achieves the high speed processing demanded by HFR encoding, while maintaining visual quality by mutual data transfers between the chips.
