"Devices to record and reproduce a sequence of signals of the video data, method for generating a sequence of signals of information on characteristic points in a sequence of signals of video data, and a recording". An apparatus for recording a sequence of signals of video data in a recording carrier has been proposed.The apparatus includes input means (1) for receiving signals from the video data, a means of generating (100) to generate signals of information of characteristic point.Processing means (100) for processing the signals of characteristic point information for a plurality of characteristic points in a sequence of signals of information of characteristic points (CPI) and means of writing (102) to write the sequence of data signals of vu00edde And the sequence of signs of characteristic points in the information recording carrier.The signs of information of characteristic point identify a characteristic point in the sequence of signals of the video data. Several measures are proposed in relation to the CPI in order to improve the quality of operations of reproduction and breeding special random access.
