Abstract: The present invention relates to a method for time base correction during generation of a digital video signal from an analog input video signal, and to an apparatus having means for digitizing an analog input video signal using such method. According to the invention, the method includes the steps of: receiving an analog video signal; generating a digital video signal from the analog video signal with a video decoder; storing at least a part of the digital video signal in a memory; detecting a portion of corrupt data having an abnormal field ordering in the digital video signal; either discarding the portion of corrupt data or replacing at least a part of the portion of corrupt data with previous data stored in the memory; and outputting the digital video signal.

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.
