Title
(EN) HIGH SPEED VIDEO DIGITAL VERSATILE DISK DISTRIBUTION AND MANUFACTURING SYSTEM
(FR) SYSTEME DE DISTRIBUTION ET DE FABRICATION DE VIDEODISQUES NUMERIQUES POLYVALENTS A GRANDE VITESSE
Abstract
(EN) A high speed recording apparatus for Digital Versatile Disk (DVD) media is described. Four or more optical write heads disposed at equidistance locations around the surface of the recordable DVD media allow for simultaneous recording of separate segments of a contiguous data stream. The data stream may be prerecorded video stored in a digital MPEG-2 format. The DVD writing apparatus spins the DVD media using constant linear velocity (CLV) at six times or more the normal playback speed of the DVD media. The high speed recording apparatus can be used with a system for capturing, storing and retrieving prerecorded videos. A central distribution site is connected via optical fiber networks to a plurality of remote distribution locations. The remote site may be a video retail store in which a selected prerecorded video title may be manufactured on DVD media in a matter of minutes for rental or sale.
(FR) Cette invention concerne un appareil d'enregistrement à grande vitesse pour supports vidéodisques numériques polyvalents (DVD). Quatre têtes d'écriture optique, ou plus, disposées à intervalles réguliers autour de la surface du support d'enregistrement DVD permettent l'enregistrement simultané de segments distincts d'un train de données contiguës. Ce train de données peut être constitué de données vidéo préenregistrées stockées sous format numérique MPEG-2. L'appareil d'écriture sur le DVD fait tourner le support DVD à vitesse linéaire constante (CLV) au minimum six fois plus rapide que la vitesse normale de lecture des supports DVD. L'appareil d'enregistrement à grande vitesse peut servir à un système permettant la saisie, le stockage et la récupération de vidéos préenregistrées. Un site de distribution central est relié par l'intermédiaire de réseaux à fibres optiques à une pluralité de points de distribution éloignés. Le site éloigné peut être un magasin de détail de vidéos dans lequel il est possible de fabriquer un titre vidéo sélectionné préenregistré sur support DVD en l'espace de quelques minutes aux fins de location ou de vente.
