Audio/video system having touch responsive function display screen
First Claim
1. An audio/video editing system comprising:
- at least one source recorder device for supplying a source of audio/video information;
a recording recorder device for recording selected audio/video information from the at least one source recorder device;
a switcher device for selectively coupling the at least one source recorder device and the recording recorder device;
computer means for providing selected edit commands;
an operator controlled input device including edit function display/indicating means for supplying serial edit function messages indicative of selected editing functions to be performed by the recorder device and the switcher device;
an operator intelligent line controller coupled to the operator controlled input device for identifying, converting and buffering the serial edit function messages in response to the computer means edit commands to provide corresponding parallel edit commands;
a plurality of device intelligent line controllers coupled to the operator intelligent line controller for establishing communication with the respective recorder and switcher devices, and for converting and buffering the parallel edit commands to define serial edit commands, in response to the computer means;
a plurality of interfaces coupled between respective device intelligent line controllers and respective recorder devices and switcher device for translating the serial edit commands to a form commensurate with the requirements of the respective devices, and for translating device edit status messages from the respective devices for return to respective device intelligent line controllers, in response to the computer means; and
said device line controllers further converting and buffering the returned device edit status messages in response to the computer means.

Abstract
An audio/video editing system presents different menus of editing functions on a display screen and changes the menus as well as performing different editing functions in response to the touching of selected areas of the display screen by an operator. An arrangement of light emitting diodes and photodetectors provides a network of beams across the face of the display screen. Selected beams are interrupted when the operator points his finger at particular characters being displayed on the screen. The display menus and editing functions are controlled by an edit controller which includes a central processing unit having a memory loaded with data from a computer file system, a character generator for providing the various menus on the display screen and a plurality of intelligent line controllers coupled to a plurality of source tape recorders, a record tape recorder and a switcher capable of coupling a different one of the source recorders to the record recorder. Each intelligent line controller which includes its own processing unit and memory controls the flow of data between the central processing unit and the various recorders and the switcher in addition to converting the data between parallel and serial forms. A separate interface coupled between each of the intelligent line controllers and an associated one of the recorders or the switcher includes processors which convert the data into a form usable by the recorder or switcher.

12. An audio/video editing system comprising:
-
at least one source recorder device for supplying a source of audio/video information to be edited; a recording recorder device for recording selected edited audio/video information from the at least one source recorder device; a switcher device for selectively coupling the at least one source recorder device and the recording recorder device; computer means for providing selected edit commands; an operator controlled input device including edit function display/indicating means for supplying serial edit function messages indicative of selected editing functions to be performed by the recorder devices and the switcher device; an operator intelligent line controller coupled to the operator controlled input device and responsive to the computer means for converting the serial edit function messages to a selected and parallel form and for buffering the messages for subsequent use as parallel edit function messages; interfaces coupled to respective recorder devices and switcher devices for translating commands to a selected form commensurate with the requirements of the respective devices and for returning serial device edit status messages indicative of the status of the respective devices; and device intelligent line controllers coupling the operator intelligent line controller with the interfaces and responsive to the computer means for establishing communication with the recorder and switcher devices via the respective interfaces, for converting the computer means edit commands to serial edit commands and the serial device edit status messages back to parallel device edit status messages, and for buffering the commands and messages in response to the computer means.
