Abstract: front page image
(EN) It is an object of the present invention to provide an apparatus of and a method of incorporating a CM or promotion video program or the like in a video program in an NVOD system. The NVOD system has control means, high-speed digital reproducing means for reproducing at a high rate a plurality of video-on-demand system recording data divided from digital data of a main program and recorded at discrete areas, an additional information program data server for reproducing data of an additional information program such as data of a CM video program, a promotion video program, or like, buffer means for selectively writing the video-on-demand system recording data from said high-speed digital reproducing means and reading the video-on-demand system recording data, and matrix switcher means for selectively outputting main program data from said buffer means and additional information data from said additional information program data server, and sequentially transmitting the main program data with the additional information data incorporating therein in a plurality of channels. The NVOD system can incorporate a CM video program, a promotion video program, or like into a video movie, and can easily update a CM video program, a promotion video program, or like.
(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.
