Disclosed are various embodiments for a system and method for encoding sub-audible codes within a signal. One exemplary embodiment includes a method that includes receiving a first digital code and a second digital code; receiving a first block and a second block of a signal; embedding an echo of the first block of the signal in the second block of the signal to create a first modified second block of the signal in accordance with the first digital code; modulating the power of the first modified second block of the signal to create a second modified second block of the signal in accordance with the second digital code; and sending a modified signal including the second modified second block of the signal.

Method and system for sub-audible signaling

A transport stream decoder/demultiplexer is provided which includes a program clock recovery circuit for recovering a program clock from program clock reference (PCR) values contained in selected transport packets. A processor is provided for extracting elementary stream data from transport packets labeled with packet identification codes (PIDs) that are specified by a host processor. The processor separately stores the elementary stream data of each stream. A host processor interface is also provided for transferring data between an external host processor and the program clock recovery circuit. A memory manager may be provided for storing the data extracted by the processor for each elementary stream in a corresponding queue. The queues may be maintained by the memory manager in an external RAM. A descrambler interface may be provided for transferring scrambled data and data derived from conditional access information between the processor and an external descrambler. In addition, at least one elementary stream interface, such as a video interface or audio interface, may be provided for outputting extracted elementary stream data for a particular elementary stream from a corresponding queue. Furthermore, a high speed interface may be provided for outputting transport packet data prior to data extraction by the processor.
