Title (EN) NEAR VIDEO ON-DEMAND SYSTEM AND TELEVISING METHOD OF THE SAME
(FR) SYSTEME DE VIDEO PRESQUE SUR DEMANDE ET PROCEDE DE TELEVISION CORRESPONDANT
Abstract:
(EN) A device and method for incorporating CMs, promotion videos, etc., in a video program in an NVOD system. The NVOD system is provided with a control means, a high-speed digital reproducing means which reproduces at a high speed main program recorded data in a form that the digital data of a video movie are divided into a plurality of parts and recorded dispersedly, a server for additional information program data which reproduces the data of CM videos, promotion videos, etc., a buffer means which selectively writes the main program recorded data sent from the high-speed digital reproducing means and reads them, and a matrix switch which selectively outputs the mains program data from the buffer means and additional information program data from the server. The NVOD system incorporates an additional information program in a main program and successively sends the main program to a plurality of channels. CM videos, promotion videos, etc., can be incorporated in a video movie, and the CM videos, promotion videos can be easily updated.
(FR) Dispositif et procédé permettant d'intégrer des pages publicitaires, des vidéos de promotion, etc. dans un programme vidéo dans un système de vidéo presque sur demande (NVOD). Le système NVOD est muni d'un dispositif de contrôle, d'un dispositif numérique de reproduction à grande vitesse, lequel copie à grande vitesse les informations du programme principal enregistré sous une forme telle que les données numériques d'un film vidéo sont divisées en une pluralité de parties et enregistrées de façon dispersée, d'un serveur pour les informations du programme supplémentaire, qui reproduit les informations des vidéos publicitaires, des vidéos de promotion, etc., d'un dispositif tampon qui écrit sélectivement les informations principales du programme enregistré envoyé par le dispositif de reproduction numérique à grande vitesse et les lit, et d'un commutateur de matrice qui produit sélectivement les données du programme principal à partir du dispositif tampon ainsi que les données du programme supplémentaire à partir du serveur. Le système NVOD intègre un programme supplémentaire dans un programme et envoie successivement le programme principal à une pluralité de chaînes. Les vidéos publicitaires, les vidéos de promotion, etc., peuvent être incorporées dans un film vidéo et les vidéos ppublicitaires et les vidéos de promotion peuvent être changées facilement.
