A standardized hot-pluggable transceiving unit comprising a housing, a SDI connector, and a signal conversion module. The housing is adapted to being inserted into a chassis of a hosting unit. The SDI connector receives a SDI signal comprising a video payload and at least one other payload. The signal conversion module is in the housing, and converts the SDI signal into a first IP flow for transporting the video payload and at least one other IP flow for transporting the at least one other payload. The generated IP flows are outputted from the SFP unit by one or more connectors different from the SDI connector. The other payload can be an audio or a metadata payload. In another aspect, a transceiving unit provides for combining a plurality of IP flows each comprising a different type of payload into a SDI signal.
