1. A computerized method comprising:

  • selecting, by an encoding device, multiple predictors for a single reference unit of correlated data, the multiple predictors located within a decoding region centered on the single reference unit in an n-dimensional coordinate space and comprising other data units in the correlated data;

    determining a sub-codebook for the decoding region in which each of the multiple predictors within the decoding region is decodable to recreate the entire single reference unit without any of the other multiple predictors, the sub-codebook having an identifier that further specifies the decoding region;

    transmitting the multiple predictors to a separate decoder; and

    transmitting the identifier for the sub-codebook as the compressed representation of the single reference unit, wherein the separate decoder recreates the entire single reference unit using the identified sub-codebook to decode any one of the multiple predictors within the specified decoding region that are correctly received by the separate decoder.
