    Abstract: PROBLEM TO BE SOLVED: To prevent unauthorized use of content by determining propriety of reproduction of content based on the decision of validity of an IC recorder which records ID in a disk. SOLUTION: An information processor acquires an ID recorder certificate including the equipment ID of the ID recorder which has recorded the ID in the disk and an ID recorder black list from the disk, and decides whether or not the equipment ID recorded in the ID recorder certificate is registered in the ID recorder black list, and further compares the issue date of the ID reorder certificate with the issue date of the ID recorder black list or an equipment invalidation date, and decides validity of the ID recorder. The reproduction of the disk recording content is stopped based on a decision that the ID recorder is the unauthorized equipment. Thus, it is possible to prevent the use of the content stored in the disk created by the unauthorized ID recorder. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To read out a grouped file at high speed. SOLUTION: An information recording and reproducing device sets Gathered information, records it on a recording medium and reads out the Gathered information, the Gathered information including information on head and end positions of a group-managed File Structure, a group-managed file (Files grouped in Fig. 14) and a backup of the grouped file (Files Back Up (grouped) in Fig. 14) among information recorded on the recording medium in a UDF format. In such a case, the information recording and reproducing device reads out the Gathered information first, thereby reads out all files of a group containing desired files at once.

    Abstract: PROBLEM TO BE SOLVED: To provide a technology of simply and surely preventing unauthorized copy of thumbnail pictures. SOLUTION: A thumbnail encoder 19 generates the thumbnail pictures of a video signal received from a terminal 12. A macro vision detection section 13, a CGMS detection update section 14, and a WM (watermark) detection update section 15 respectively detect an analog copy protection signal (APS) of the video signal received from the terminal 12, a CGMS signal as copy generation management information or an a watermark, and provide an output of them to a controller 21. The controller 21 generates copy limit information of the thumbnail pictures on the basis of the copy limit information. An information recording medium 26 records the thumbnail pictures and the copy limit information. The video signal processing apparatus or the like is applicable to recording and reproducing apparatuses. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To efficiently record an encoded stream onto a recording medium and to speedily perform random access. SOLUTION: An inputted transport stream is divided for each time unit having a prescribed length and among packets included in each time unit, the packets of a channel, to which recording is designated, are collected and recorded on the recording medium without adding any dummy packet. The data length of a time unit TU0 expressed with a value subtracting a leading address A (TU0) of the time unit TU0 from a leading address 'time unit address' of a recorded packet among respective time units TU0, TU1 and TU2 such as leading address A (TU1) of a time unit TU1, for example, is correspondently recorded on the recording medium as a time unit map.

    Abstract: PURPOSE:To prevent performance from being lowered by cancelling defocus due to the displacement of a spot reflected by an optical disk substrate and thrown on a four-division photodiode. CONSTITUTION:The output Z0 of an arithmetic circuit 13 for focus error components is supplied to an adder circuit (or a subtraction circuit 17), and the outputs X and Y from arithmetic circuits 14 and 15 for the displacement components in the directions of x-axis and y-axis are supplied to a multiplication circuit 16 for muliplying a constant -alpha and the values of displacement X and Y in amount are multiplied by the constant -alpha=-pi/4s, and the multiplication result is supplied to the adder circuit (or subtraction circuit) 17 to perform the addition (subtraction) of Z0-alpha.X.Y. As a result, a true focus error signal FE0 is produced and amplified by a focus error amplifier 18, and then undergoes a phase compensation circuit 19 for phase compensation and is supplied to a drive amplifier 20, and a focus actuator 23 is driven by the drive amplifier 20 to always keep a focus lens 3 at a proper focus position relative to an optical disk substrate 4 for focus servo.

    Abstract: PURPOSE:To stabilize focus setting without issuing the switching signal to a focusing servo by controlling a focusing error signal shutting out the light source of an optical system when an objective lens approaches to an optical disk surface (focus setting. CONSTITUTION:A focusing actuator 52 is driven by a setting driving signal S1 and an objective lens 53 mounted on the actuator 52 is driven so as to be approach to or separated from the surface of an optical disk 50. Focus setting action is executed by means of a focusing error signal SER1. When the lens 53 approaches to the surface of the disk 50, an emitting laser source 55 of the optical system 54 is shut out by the actuator 52 and when the lens 53 is separated from the surface of the dusk 50, the laser source 55 emits beams. Thus, at the time of falling of the saw-tooth wave of the driving signal S1, i.e., in the course in which the lens 53 approaches to the surface of the disk 50 the laser source 55 is turned off. In the meantime, focus setting action is executed and the state of the focusing servo is made stable.
