Abstract
A video apparatus has a digital encoder which receives a first analogue video signal with ancillary information in a given time window and generates on an output a digital stream based on the first analogue video signal. A digital decoder is connectable to this output to generate a second analogue video signal. A switch selects between the first analogue video signal and the second analogue video signal as an output depending on a control signal based on the occurrence of said time window.
