摘要： The invention relates to a communication system comprising a central station (1), provided with a memory (MEM) and a connection device (COM) to at least one communication network (NET). Said communication system provides video information, in particular digitalized images and films, which are transmitted via said communication network (NET) to each remote station (2), connected to said network. Said video information is optionally buffered into said remote station (2) and displayed on a visual display terminal (VID2). According to said invention, the memory (MEM) of said central station (1) is an electronic memory (MEM), in which several video information blocks (VIDB) are to be memorized, which are recorded in an index (CONT). Said memory transmits one of the selected information blocks (VIDB) to the respective communicating remote station (2) by means of a management program (ADM) depending on the demand and keeps a record thereof in a statistical and/or accounting memory area (AS).
