    摘要: An interactive television system (10b) 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 received 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 transmitted via broadcast or cable TV and received (28) by VCR used as a tuner (12) or by a simplified TV head-end tuner, with the transmitted television signal having the audio channels either multiplexed into the video line or the existing audio channels. The received television signal is 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) and computer control (18, 22, 24, 26) to provide the interactive display.
