SDTI

Serial Digital Transport Interface (SMPTE 305M). Based on the 270 Mb/s standard definition SDI, this provides realtime streaming transfers. It does not define the format of the signals carried but brings the possibility to create a number of packetized data formats for broadcast use. There are direct mappings for SDTI to carry Sony SX, HDCAM, DV-DIFF (DVCAM, DVCPRO 25/50, Digital-S) and MPEG TS. There is also an HD version. Standardized as SMPTE 348M this provides a 1.5 Gb/s data link.
