NTT has developed a real–time 4K high frame rate HEVC codec for the live transmission of high frame rate (HFR) video. The codec doubles the frame rate of the standard video frame rate (SFR), from 50/60p to 100/120p.
NTT has demonstrated a 4K HFR HEVC encoder appliance and a 4K HFR HEVC decoder appliance, both of which are 1U size.
The 4K HFR HEVC encoder appliance provides backward compatibility by supporting temporal–scalable encoding, meaning the output stream can be decoded by conventional SFR decoder to yield 4K SFR video.
Moreover, our codec supports the MPEG Media Transport (MMT) protocol which enables hierarchical transmission. 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.
