Systems and methods for highly efficient video compression using selective retention of relevant visual detail

A system for video stream compression, said system comprising:

• a processor for separating an available video stream into first and second video streams, said first video stream containing exclusively low frequency data obtained from said available video stream and said second video stream containing all remaining data obtained from said available video stream;
• said processor further operative for suppressing certain details from said second video stream to produce a third video stream with reduced information content;
• and
• a transmitter for sending both said first and said third video streams to a remote location in compressed format.

A method for compressing an input digital video stream, said method comprising:

• spatially filtering low frequency components from said input video stream to create an encoded carrier stream;
• decoding said carrier stream;
• producing a raw detail video stream by subtracting said decoded carrier stream from said video stream;
• producing a trimmed detail video stream by applying suppression to certain details in said raw detail video stream;
• and
• encoding said trimmed detail video stream.

A method for reducing the bandwidth requirement for delivering a digital video signal from a source to a destination, said method comprising:

• down sampling an accepted a digital video signal from a source to form a signal having relatively low resolution components of said digital video signal;
• encoding said low resolution signal components for transmission;
• using said down sampled signal to remove from said accepted digital signal said low resolution components, thereby creating an AC signal;
• and
• encoding said AC signal for transmission in conjuntion with said encoded low resolution signal.
