发明名称 Interaktive Mehrfachfernsehsendung
摘要 Different components of television programs, such as the video and audio components or different time segments of the program, are assigned to different channels transmitted in the form of packetized digital information in at least one of the channels of a multi-channel cable television distribution system. A particular subscriber's converter (200) is configured to receive a particular subset of program components by enabling the converter to receive the virtual channels (in 208) carrying the components in such subset. An embodiment is disclosed in which different combinations of program segments are enabled for different subscribers. Another embodiment is disclosed in which the viewing of a program by multiple subscribers who begin viewing at different times is synchronized by using "filler" program segments having different lengths. <IMAGE>
