rate for the interface between display/camera and storage/codec should also be ex-
ponentially increased as shown in Fig. 47. To satisfy the needs of I/O interface for
4K UHD Video, the standardization of 25Gbps serial optical interface for studio
use is currently under consideration in SMPTE 32-NF-30.
