Serial Digital Transport Interface (SDTI) is based on SDI, allowing native video formats
to be sent in real time within an SDI video stream. SDTI does not define a specific video
signal format but instead uses the structure of SDI to carry any kind of data. This allows
video facilities to use their existing SDI patchbays and routers to transfer other native
video formats, or transfer any kind of data. For example, some DV decks can transfer
DV via SDTI, which means native DV can be transferred long distances over existing
coaxial cable instead of the usual FireWire connection. Other formats, such as HDCAM
and MPEG, can also be transferred via packets within an SDTI transport stream.
