1. A remote site interactive system, comprising:
- a host system having an instructor console;
at least one remote system having a base unit;
a communication system between said host system and said base unit which is adapted to communicate an instructor audio signal from said host system to said base unit and a respondent audio signal from the base unit to the host system;
said communication system including an audio enhancer which enhances at least one of said audio signals by regulating at least one chosen from signal level, signal muting and signal source authenticity;
wherein said audio enhancer sends a reference signal over said communication system from one of said host system and said base unit to at least the other of said host system and said base unit and measures said reference signal at the other of said host system and said base unit; and
wherein said audio enhancer regulates signal muting by measuring delay of said reference at said other of said host system and said base unit.

23. An interactive system for providing interaction between an instructor at an instructor location and a plurality of respondents located at at least one geographically separated site, wherein said interactive system is useful with an audio-video transmission system including a studio at the instructor location having audio-video equipment which supplies audio-video information and a communication system which downloads audio-video information from audio-video equipment to an audio-video monitor at the at least one geographically separated site, said interactive system comprising:
-
a host system having an instructor console and an instructor microphone adapted to be in a studio;
said host system further including a phone line manager adapted to be connected with at least one phone line;
at least one remote system having a base unit old at least one respondent microphone, wherein said base unit is adapted to be connected with at least one phone line;
wherein said host system coordinates with said base unit to measure communication system delay between the studio and an audio-video monitor at the at least one geographically separated site;
wherein said host system generates a time stamp upon sending test signal;
wherein said base unit is adapted to measure the level or the test signal and the gain said base unit applies to an audio portion of the forwarded audio-video information is adjusted as a function of the measured level of the test signal; and
wherein said base unit sends level data to said host system of the measured level of the test signal and said host system adjusts gain said base unit applies to the audio portion of the forwarded audio-video information in response to the level data received from the base unit. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. An interactive system for providing interaction between an instructor at an instructor location and plurality of respondents located at at least one geographically separated site wherein said interactive system is useful with an audio-video transmission system including a studio at the instructor location having audio-video equipment which supplies audio-video information and a communication system which downloads audio-video information from audio-video equipment to an audio-video monitor at the at least one geographically separated site, said interactive system comprising:
-
a host system having an instructor console and an instructor microphone adapted to be in a studio;
said host system further including a phone line manager adapted to be connected with at least one phone line;
at least one remote system having a base unit and at least one respondent microphone wherein said base unit is adapted to be connected with at least one phone line;
wherein said host system coordinates with said base unit to measure communication system delay between the studio and an audio-video monitor at the at least one geographically separated site; and
wherein at least one of said host system and said base unit establishes a mute of the audio portion of the audio-video information from the studio to an audio-video monitor at the at remote site as a function of measured communication system delay. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)

53. In an interactive system for providing interaction between an instructor at an instructor location and a plurality of respondents located at at least one geographically separated site, wherein said interactive system includes a host system at said instructor location and a remote system at said at least one geographically separated site, wherein said host system has an instructor console including an instructor microphone and a phone line manager adapted to be connected with at least one phone line, said interactive system further including a studio at said instructor location having audio-video equipment which supplies audio-video information, said remote system including a base unit and at least one respondent microphone, wherein said base unit is adapted to be connected with at least one phone line, said interactive system further including a communication system which downloads audio-video information from the audio-video equipment at the studio to an audio-video monitor at the at least one geographically separated system, a method of enhancing signal transmission from at least one of said host system and said base unit to at least the other of said host system and said base unit comprising:
-
sending a test signal from at least one of said host system and said base unit and analyzing the test signal received at the other of said host system and said base unit;
determining a time delay between sending the test signal from the one of said host system and said base unit and receiving the test signal at the other of said host system and said base unit, wherein said time delay is of said communication system; and
adjusting muting of said base unit as a function of said delay. - View Dependent Claims (54, 55, 56, 57, 58)
