ABSTRACT:
A method of communicating data from a first location to a second location employing a vector quantization data compression technique that allows users to select the reproduction quality of the transmitted vector quantized data. According to the method, data is encoded (compressed) from the last level of a first tree search vector quantization codebook at the first location. A second tree search vector quantization codebook is provided at the second location having a number of levels equal to or less than the number of levels in the first codebook. The reproduction quality of the transmitted vector quantized data is a function of the number of levels in the second codebook.
