    摘要: An interactive cable television system utilizes a standard cable television distribution network for simultaneously providing a plurality of viewers with an interactive television program comprising a plurality of signals related in time and content. Video signals (1) are transmitted in a digital format, more than one signal being multiplexed onto a data stream on a single channel. The video signals (1) may be compressed for efficiency. A receiver (7), in conjunction with a signal selector (8), selects a particular NTSC channel for playback, then selects a particular video signal from the data stream, and decompresses the video signal for playback. Seamless switching between video signals on different channels is provided. In an alternative embodiment, the various signals which comprise the interactive program are switched at the head end (300) rather than at the receiver (7). The multiple choice control unit (9) selects a desired signal by relating the multiple choice selections of the user through a relay box (17) back to a remotely located switching station. The switching station routes the correct video signal down the appropriate cable channel for the particular user.

    摘要: A distributed community network (200) provides services to an arbitrarily large community of end users (204, 206, 208) by distributing the load among many machines (210, 212, 214). The network uses hubs (220,222, 224) on the machines for routing packets. The hubs (220, 222, 224) obtain routing instructions from a router (256) and use those instructions for routing the packets. The packets include content for the machines based upon a particular network service, such as a chat service (218) permitting users to interact in chat rooms, or a push/pull service (228) for pushing content to the user machines either directly or based upon information received from the users.

    摘要: A method of programming an interactive scenario on a multitrack storage media (4) is disclosed. The interactive scenario includes a number of time-synchronized frames on separable data streams which are related in content to one another. The interactive scenario is played back on an apparatus (2) which includes means for selectively retrieving the data streams at a given time. A decision-making goal is defined for the interactive scenario. Once the goal has been defined, a set of rules is developed, preferably using knowledge derived from an expert, which lead to the defined goal. The rules relate hierarchically whereby the conclusions of at least some of the rules are premises for other rules. The rules also logically relate whereby the conclusion of a final rule or rules corresponds to the decision-making goal. If the rules require premises to be obtained, queries are generated to interactively ask for the premises.

    摘要: An interactive television system (10) for provi­ding full motion synched compatible audio visual dis­plays based on dynamic user selection (26) of a plura­lity of syllable synched compatible audio choices for a common full motion video frame presentation provided over a common television channel. Two or more audio channels are synched to a common video channel, with the video being compatible with all audio channels. The interactive programming is stored on video cassette (12), or other storage media and the audio channels are either multiplexed into the video line or the existing audio channels and are provided to a control module (14) which demultiplexes the signal (16) and ultimately combines the user selected audio signal with the video in an RF modulator (20) under computer control (18, 22, 24, 26) to provide the interactive display.
