摘要： In order to avoid, during trick mode, jittering of a second image superimposed on a first image, the arrangement is able to provide a signal including a vertical synchronisation signal and representative of a first image to a screen. The arrangement also generates a second image to be synchronised with the first image. The arrangement is able to perform a pseudo-vertical synchronisation signal. A selection is made to use whether the vertical synchronisation signal or the pseudo vertical synchronisation signal depending on the mode in which the arrangement is functionning.

摘要： A VCR is connectable to a television receiver and a decoder of scrambled signal. The VCR provides connection paths for coupling a video signal and an audio signal between the television receiver and the decoder. The VCR receives a control signal from the decoder indicating whether the video signal received by the television receiver is scrambled. In a first stand-by mode of the VCR, if the video signal is not scrambled, only the video signal is routed to the decoder through the VCR. If a scrambled signal is received, then the audio signal is also routed to the decoder through the VCR.

摘要： The present invention proposes a method for generating a digital video signal from an analog input video signal, which prevents picture jitter in the digitized video signal when the analog input video signal is not in complete conformity with a standard. According to the invention, the method includes the steps of: detecting the type of signal source; in case the type of signal source is a non-standard type, detecting the existence of an error state; converting the analog input video signal to a digital video signal; in case an error state exists, replacing an error prone part of the digitized video signal with a substitute signal part; and in case the type of signal source is a standard type or no error state exists, keeping the digitized video signal unchanged.
