Embedding of internet protocol packets in an SDI or SDTI signal

摘要

An SDTI signal has, in the horizontal ancillary data space (HANC), in addition to the SDTI header data, Internet Protocol (IP) packets embedded in one ore more ancillary data packets. An SDI system comprises a plurality of video signal processors (2, 10) interconnected via SDI interfaces. The SDI interfaces include means (14, 16) for deriving from the horizontal ancillary data space, and for inserting into the horizontal ancillary data space, Internet Protocol (IP) packets embedded in one or more ancillary data packets.
