APPARATUS AND METHOD FOR ADDRESSING CONTROL IN A NETWORK FOR DISTRIBUTED CONTENT DATA

摘要

In a content data distribution network, a system for directing control instructions to selected ones of a plurality of receivers. The system comprises a stored value (304), stored in a memory location (108) reserved for at least one local parameter in each of the plurality of receivers. An uplink distributes to the plurality of receivers over said content data distribution network a transmitted value (306). The system compares the stored value (304) and transmitted value (306) such that a True value corresponds to the selected ones of the plurality of receivers at which the control instructions are to be executed. Comparisons may be made to functions of the stored values (304). Comparisons may be made to multiple stored values (304). Multiple comparisons may be connected together with boolean operators. The stored values (304) can be changed by the transmitted control instructions.
