摘要： A recording method, particularly suitable for use in a digital video-camera, is described according to which a digital signal (10), deriving from the encoding of an audio- video signal is temporarily stored in a buffer (11) and from there recorded in a dual layer DVD (12) in successive recording intervals (22) or packets. The start/stop of a recording interval is normally controlled according to the level (15) of filling of the buffer. The digital signal is partitioned in portions that need to be entirely recorded on one single layer, and this triggers the need for a layer jump independently from the level of filling of the buffer. In order to avoid starting a layer jump with the buffer already partly filled, and therefore having a short non-recording interval (23) when time is mostly needed for calibrations, it is proposed to adjust the resolution in the encoding of the audio-video signal so as to have the buffer close to empty when the layer jump occurs.

摘要： A method is disclosed of recording an input signal 21 on an information carrier 12, comprising the steps of: - encoding the input signal so as to obtain a digital signal 10, with a level of resolution at an initial value, - storing the digital signal in a buffer 11, - recording the digital signal stored in the buffer on the information carrier, - temporarily suspending the recording, and - while the recording is temporarily suspended, having the level of resolution decreased to a lower value in encoding the input signal, wherein in decreasing the level of resolution to the lower value, said level of resolution is decreased gradually. In this way it is obtained that the decrease in the level of resolution is less perceptible during reproduction of the input signal.

摘要： A recording method, particularly suitable for use in a digital video-camera, is described according to which a digital signal (10), deriving from the encoding of an audio- video signal is temporarily stored in a buffer (11) and from there recorded on a dual layer DVD (12). The need for a layer jump occurs, independently from the current level of filling of the buffer, when a storage space associated to a first layer has been exhausted. In order to be able to store the digital signal in the buffer while the layer jump is accomplished, it is proposed to decrease the resolution in the encoding of the audio-video signal, so as to have the level in the buffer growing relatively slowly when the layer jump occurs.
