Abstract
A data communication system transports a sequence of digital data frames that convey client input data encoded with secondary data. The system can utilize known, proprietary, or future techniques for digital data encoding, digital watermarking, data encryption, or the like. The secondary data can be frame alignment data, private data intended only for certain destination devices, and/or other data types. In a practical embodiment, the data frames are compliant with optical transport networks.
