A video apparatus, for instance a video player, comprises a first digital source (e.g. a media player) of a first video digital stream and a video encoder (for generating analogue video signals based on said first video digital stream. The video apparatus also has an input for receiving first analogue video signals comprising synchronization signals.A second digital source generates a second video digital stream based on which the video encoder can generate second analogue video signals synchronized by the synchronization signals of the first analogue video signals for superimposition on the first analogue video signals.
