Standardized hot-pluggable transceiving unit implementing a cloud gateway functionality. The transceiving unit receives a source video IP flow. At least one processing unit in the housing executes a HTTP client and a conversion function. The HTTP client establishes a connection with a HTTP server hosted by a cloud video server, and receives the source video IP flow from the HTTP server of the cloud video server via the first connector. The source video IP flow uses one of the HTTP or the HTTPS protocol. The conversion function generates a video stream based on the source video IP flow, and the video stream is outputted by the transceiving unit. Alternatively, the transceiving unit receives a source video stream converted in a video IP flow by the conversion function, and the HTTP client uploads the video IP flow to the HTTP server of the cloud video server.
