Abstract
Digital data to be communicated are provided with error correcting code. Between consecutive signals representing real, or valid data (pixels in TV transmission) there are interpolated "phantom" data signals so chosen as to maintain the encoded signal within the limited frequency spectrum available for communication. Upon reception, the valid data (pixels) are extracted from the sequence of valid and interpolated data (phantom pixels), thereby reconstituting the original valid data.

A system for communicating a sequence of digital data from a transmitter to a receiver, comprising:
- means at the transmitter for interpolating one or more phantom data between consecutive ones of said digital data that have an amplitude transition with an associated frequency component that exceeds a predetermined frequency spectrum for transmission, each of said one or more phantom data having an amplitude value which lies between the amplitude values of said consecutive digital data, to generate an interpolated data sequence maintained within the predetermined frequency spectrum;
- and
- means at the receiver for separating said digital data from said phantom data to reproduce the sequence of digital data.
A method for communicating a sequence of digital data from a transmitter to a receiver, comprising:
- at the transmitter, interpolating one or more phantom data between consecutive ones of said digital data that have an amplitude transition with an associated frequency component that exceeds a predetermined frequency spectrum for transmission, each of said one or more phantom data having an amplitude value which lies between the amplitude values of said consecutive digital data, to generate a interpolated data sequence maintained within the predetermined frequency spectrum;
- and
- at the receiver, separating said digital data from said phantom data to reproduce the sequence of digital data.
In a transmitter for communicating a sequence of digital data to a receiver, a combination comprising:
- a digital data source for providing a sequence of digital data;
- a data formatter for interpolating one or more phantom data between consecutive ones of said digital data that have an amplitude transition with an associated frequency component that exceeds a predetermined frequency spectrum for transmission, wherein each of said one or more phantom data having an amplitude value which lies between the amplitude values of said consecutive digital data, thereby producing an interpolated data sequence within the predetermined frequency spectrum for transmission.
