    Abstract: An apparatus for recording a sequence of video data signals on a record carrier (3) has been proposed. The apparatus comprises input (1) means for receiving video data signals, generating means (100) for generating characteristic point information signals, processing means for processing the characteristic point information signals for a plurality of characteristic points into a sequence of characteristic points information signals (CPI) and writing means (108) for writing the sequence of video data signals and the sequence of characteristic points information signals on the record carrier (3). The characteristic point information signals identify a characteristic point in the sequence of video data signals. Various measures are proposed in relation to the CPI aiming at providing compact way of storing information related to a size of I-pictures.

    Abstract: A method for recording video information for controlling video information copy limit information when copying data recorded on a recording medium to another recording medium. By detecting copy limit information (CCI) or a watermark (WM) of an AV stream to be input, it is checked whether the content of the copy limit information or the watermark has been changed. Change point information of the copy limit information or the watermark and the content of the copy limit information or the watermark are fetched. According to the change point information fetched, control information is generated for controlling the copy limit information. When the input signal has ended, a code for preventing altering is calculated, it is confirmed that the copy limit information or the watermark has not been altered, and the control information generated is recorded together with the video information to the recording medium of copy destination.

    Abstract: A disk apapratus includes an optical pickup (5) for making access to an optical disk (4) having read-only regions and writable regions arranged alternatively at predetermined radial intervals and storing boundary write track position information representing adjacent read-only region and writable region; a thread motor (11) for moving the optical pickup (5) in the disk radial direction; an RF amplifier (7), in response to the output from the optical pickup (5), for generating a traverse signal whose level changes each time the optical pickup (5) traverses the write track at first setting corresponing to the read-only region or second setting corresponding to writable region selected on the basis of a switch signal when the optical pickup (5) is moving; a servo circuit (9) having counting means for counting the number of write tracks traversed on the basis of the traverse signal; and a system controller (8) for outputting the switch signal to the RF amplifier (7) on the basis of the number of write tracks output from the present track position to the boundary write position and on the basis of the number of write tracks counted by the servo circuit (9) when the boundary write track position exists between the present write track position which is accessed at present by the optical pickup (5) and is detected by the present position detection means and the target write track position.
