Abstract

Disclosed is a method, circuit and system for transmission and reception of data, including video data. There is provided a multi-constellation data to symbol mapping logic, circuit or module integral with or otherwise functionally associated with a transmitter and a corresponding multi-constellation symbol to data de-mapping logic, circuit or module integral or otherwise functionally associated with a receiver. The multi-constellation mapping and corresponding de-mapping logic, circuit or module may be characterized by a non-uniform distribution of symbols, and optionally may be characterized by a set of symbol clusters, wherein symbol clusters are of the same or varying sizes and may be spaced either at uniform or non-uniform distances from one another.
