Interactive program reception and generation system, and how to provide a single complex interactive signal

摘要

In addition to the usual general programs, subscribers with an interactive component 600 connected to a television 186 or personal computer display 187, a system for simultaneous broadcasting of a fully interactive program with the same standard video signal bandwidth, are active. In addition to being able to participate, the general television set 186 allows viewers to watch a general program. An important feature is that conversational activity is optionally provided to users who do not possess the interactive component 600 without any degradation or interruption of program content. Conversation activity is made private through the use of alternative audio responses and / or graphical display that may be provided as part of the transmitted video signal bandwidth. The interactive elements appear to the subscriber immediately after the subscriber entry and / or later at the explicit “trigger point” 900. At trigger point 900, program content is subtly changed in accordance with the particular interests present to each interactive subscriber.
