Patent ID: 7317840

Claim:
A system for transmitting audio and video via a communication medium, comprising: an audio input; a video input; an image capture mechanism operably linked to said video input; an audio encoder operably linked to said audio input; a wavelet transform image encoder and decimator operably linked to said image capture mechanism; a communication medium; an inverse wavelet transform image decoder and interpolator operably linked to said communication medium, wherein said interpolator uses a computer program to: receive image data comprising a (j+1)th level vector X j+1 of low frequency wavelet transform coefficients; decode and expand said received image data using an inverse wavelet transform, to generate a low-pass filter matrix H j , a high-pass filter matrix G j , a high-pass synthesis matrix G j , and a low-pass synthesis matrix H j , compute an estimation matrix M according to the equation: M=|αI j + G t j H t j H j G j | −1 G t j H t j G j G j , in which the subscript “t” refers to the matrix transpose; I is the identity matrix, and where α is a positive scalar such that α→0 as the accuracy of the X j+1 increases, and estimate a jth-level vector X j of wavelet transform coefficients according to the equation: X j =TX j+1 , where T is the rectangular matrix defined by the equation: T= H j + G j M; an audio and video synchronizer; and a receiver for replaying said audio and decoded video images.
