Abstract
An interface permits bi-directional data signal transfer between the microcomputer of the receiver and an addressable controller-decoder designed for use in conjunction therewith. The data transfer permits expansion of the receiver functions and future adaptability to a variety of satellite services. The interface transfers messages from the microcomputer representing keystrokes received from the receiver keyboard and the status of the various receiver components and receives commands from the decoder for regulating the operation of the receiver components and for the transfer of specific information. The data transfer is achieved through a serial communication protocol which facilitates the interaction between units.
