Abstract:
1. A data modification device, said data modification device comprising: a data modification unit coupled to an incoming data terminal, a local data terminal, and a data distribution terminal, wherein the data modification unit is adapted to selectively combine data from the incoming data terminal and the local data terminal in accordance with an instruction set; a data stripper for extracting meta data parameters from a data signal wherein the extracted meta data parameters include a substitution determination parameter, said substitution determination parameter having an evaluation type field for specifying an evaluation type and an evaluation value field for specifying an evaluation value to correspond with the evaluation type, the evaluation type and evaluation value for determining when a subset of original broadcast meta data in said data signal should be replaced, wherein the evaluation type is selected from the group comprising of priority comparison, string comparison, and numeric comparison and the evaluation value is selected from the group comprising of priority level, geographical information, and unique ID; an evaluator for evaluating the substitution determination parameter, said evaluator performing an evaluation of said evaluation type on said evaluation value with respect to a local state of said data modification device; and an inserter for substituting said subset of original broadcast meta data in the data signal with local meta data based on the evaluator comparison.
