07 Dec 2001TL;DR: In this paper, a marking is formed by a laser on a reflective film of a disk holding data written thereon and at least position information of the marking or information concerning the position information is written on the disk in an encrypted form or with a digital signature appended thereto.
Abstract: An object of the present invention is to provide a marking forming apparatus, a method of forming a laser marking on an optical disk, a reproduction apparatus, an optical disk, and a method of manufacturing an optical disk, capable of providing a greatly improved copy prevention capability as compared to prior known construction. To achieve this object, in the optical disk of the invention, for example, a marking is formed by a laser on a reflective film of a disk holding data written thereon and at least position information of the marking or information concerning the position information is written on the disk in an encrypted form or with a digital signature appended thereto.

15 Oct 1981TL;DR: An optical information reading device adapted to apply a light beam from a light source to an information carrier having information recorded thereon as convexities and concavities or variations in a light reflecting factor, and to receive the light reflected from the information carrier, thereby to read the information as mentioned in this paper.
Abstract: An optical information reading device adapted to apply a light beam from a light source to an information carrier having information recorded thereon as convexities and concavities or variations in a light reflecting factor, and to receive the light reflected from the information carrier, thereby to read the information. A specific arrangement of optical elements such as a beam splitter, lens, and reflecting mirror enables the information reading device as a whole to be reduced in size particularly in length in the direction perpendicular to the plane of the information carrier.

29 Jun 2004TL;DR: In this article, a video/audio recorder/reproducer comprising a section (100) for inputting main video and audio information, a section(110) for audio information (voice memo) being added to the main information and a control section (120) for controlling the operation of each section.
Abstract: A video/audio recorder/reproducer comprising a section (100) for inputting main video/audio information, a section (110) for inputting audio information (voice memo) being added to the main information, a section (140) for recording/reproducing video/audio data, a medium (150) for recording video/audio data, and a section (120) for controlling the operation of each section. The control section (120) records the audio adding information on the recording medium (150) in association with a specified frame position in the main information. The specified frame position is specified by a time code, offset (number of frames from the head of the main information), and the like.

19 Aug 2005TL;DR: In this article, a control method of synchronizing communications between or among a plurality of devices in a communication system includes detecting beacons from the plurality of nodes in the communication system, and establishing a reservation for at least a portion of the nodes.
Abstract: A control method of synchronizing communications between or among a plurality of devices in a communication system includes detecting beacons from the plurality of devices in the communication system, and establishing a reservation for at least a portion of the plurality of devices in the communication system. Each reservation is a frame interval in which to transmit symbols from one device to one or more of the other devices in the communications system. Each frame interval and intra-frame interval is set according to the established reservation. Each frame interval and intra-frame interval is a plural, integral number of symbol periods in duration.

24 Feb 2000TL;DR: In this article, a speech understanding system for receiving a spoken request from a user and processing the request against a knowledge base of programming information for automatically selecting a television program is disclosed.
Abstract: A speech understanding system for receiving a spoken request from a user and processing the request against a knowledge base of programming information for automatically selecting a television program is disclosed. The speech understanding system includes a knowledge extractor for receiving electronic programming guide (EPG) information and processing the EPG information for creating a program database. The system also includes a speech recognizer for receiving the spoken request and translating the spoken request into a text stream having a plurality of words. A natural language processor is provided for receiving the text stream and processing the words for resolving a semantic content of the spoken request. The natural language processor places the meaning of the words into a task frame having a plurality of key word slots. A dialogue manager analyzes the task frame for determining if a sufficient number of key word slots have been filled and prompts the user for additional information for filing empty slots. The dialog manager searches the program database using the key words placed within the task frame for selecting a program, and produces a signal for selecting a television channel associated with the program.
