Systems and methods for using transport stream splicing for programming information security

Apparatus and methods for indicating the identity of a device for receiving and retransmitting programming information. The device, which may be a set-top box or suitable communication network receiver, may be configured to receive a broadcast signal from an antenna, which may be a satellite, a cable, an electronic communication network or any other suitable source. The programming information may be any type of audio or video data, or any other suitable type of data. The broadcast signal may have multiple channels that include the programming information. Each of the channels may include a distinct watermark. The device may splice between the channels to generate a signature that the device may embed in an output data stream that may be used to display or perform the programming information.
