<p>A video apparatus has a digital decoder (38) generating a first digital stream (YCbCr3), a video source (24) of a first analogue signal (A1), a video encoder (42) and a first video decoder (28) connectable to the video source (24) for generating a second digital stream (YCbCr1) based on the first analogue signal (A1). A switch (40) is coupled to the first video decoder (28) and to the digital decoder (38) to notably mix the second digital stream (YcbCr1) and the first digital stream (YCbCr3) into an output digital (YCbCrout) stream to the video encoder (42).</p>
