Apparatus for generating video output data stream, video source, video system, and method for generating video output data stream and video source data stream

摘要

A device for generating a video output data stream includes first and second signal inputs for receiving first and second video source data streams and a video output data stream at a first time point based on a first video source data stream And providing by means of switching means, based on a second video source data stream at a second time following the first time point. The apparatus further comprises a control signal output for transmitting a control command to a video source providing a first or second video source data stream. The control command includes an indication to the video source that applies a switching effect located between the image of the first video source data stream of the video output signal and the image of the second video source data stream.
