VIDEO APPARATUS

摘要

A video apparatus has a digital encoder (4, 6) which receives a first analogue video signal (A1) with ancillary information in a given time window and generates on an output a digital stream (MPEG) based on the first analogue video signal (A1). A digital decoder (8) is connectable to this output to generate a second analogue video signal (A2). A switch (20) selects between the first analogue video signal (A1) and the second analogue video signal (A2) as an output depending on a control signal (CTL) based on the occurrence of said time window.
