要約
(EN)
Broadcast program videos from a plurality of broadcast reception units (10, 20) are distributed by a video distribution unit (51).  At least one of the distributed program videos is made to be a main screen while the other program videos reduced via video reduction units (52, 53) are made to be child screens.  The main screens and the child screens are combined by video synthesis units (54, 55).  A video consisting of the combined main screen and the child screens are displayed on a plurality of monitors (92, 97).
(FR)
Selon l'invention, des vidéos de programme de radiodiffusion provenant d'une pluralité d'unités de réception de radiodiffusion (10, 20) sont distribuées par une unité de distribution vidéo (51). Au moins l'une des vidéos de programme distribuées est conçue pour être un écran principal, tandis que les autres vidéos de programme réduites par des unités de réduction vidéo (52, 53) sont conçues pour être des écrans enfants. L'écran principal et les écrans enfants sont combinés par des unités de synthèse vidéo (54, 55). Une vidéo constituée de l'écran principal et des écrans enfants combinés est affichée sur une pluralité de moniteurs (92, 97).
(JA)
 複数の放送受信部10,20からの各放送番組映像を映像分配部51により分配して、分配した番組映像のうちの少なくとも1つの番組映像を主画面とし、映像縮小部52,53を通して縮小処理した他の番組映像を子画面として映像合成部54,55により合成し、合成した主画面及び子画面からなる映像を複数のモニタ92,97毎に表示する。
