`
`Mum-CHANNEL C‘BLE SYSTEM
`
`A unified system of programming communication. The sys-
`tem encompasses the prior art (television, radio, broadcast
`hardcopy, computer communications, etc.) and new user spe-
`cific mass media. Within the unified system, parallel process-
`ing computer systems, each having an input (e.g., 77) con-
`trolling a plurality of computers (e.g., 205), generate and
`output user information at receiver stations. Under broadcast
`control, local computers (73, 205), combine user information
`selectively into prior art communications to exhibit person-
`alized mass media programming at video monitors (202),
`speakers (263), printers (221), etc. At intermediate transmis-
`sion stations (e.g., cable television stations), signals in net-
`work broadcasts and from local inputs (74, 77, 97, 98) cause
`control processors (71) and computers (73) to selectively
`automate connection and operation of receivers
`(53),
`recorder/players (76), computers (73), generators (82), strip-
`pers (81), etc. At receiver stations, signals in received trans-
`missions and from local inputs (225, 218, 22) cause control
`processors (200) and computers (205) to automate connec-
`tion and operation of converters (201), tuners (215), decryp-
`tors (224), recorder/players (217), computers (205), furnaces
`(206), etc. Processors (71, 200) meter and monitor availabil-
`ity and usage of programming.
