A module containing digital compression and decompression circuitry is used in conjunction with a system whereby a video program may be communicated over a telephone line to an RF broadcaster to be received by individuals at remote locations equipped with one of the modules. In the preferred embodiment, the RF transmitter is an FM transmitter, and the video broadcasts are modulated onto a subcarrier, such as an SCA subcarrier. The module has various other inputs and outputs adapted for connection to other video-related devices and/or a personal computer which may be used for control or program production. A configuration is also described whereby multiple modules may be used in conjunction with a conference control module enabling multiple participants to view one another as part of a gathering such as a classroom instruction situation.
