Digital data encoding and decoding method and system is provided. The method for digital data communication include encoding bit stream having monitoring a specific bit pattern in the bit stream when a frame signal is received, and based on the monitoring, creating a unique encoding pattern for the frame signal in encoded data. The system for digital data communication includes an encoder having a control unit for monitoring incoming bit stream to detect a specific bit pattern at a bit position relative to a frame signal and asserting a control signal, and a mark and space unit for generating encoded data having at least one of one or more marks and one or more spaces, based on the bit stream in response to the control signal so that the frame signal is embedded into the encoded data. The method for decoding includes recovering bit stream from encoded data. The encoded data is generated using a unique encoding pattern for a frame signal in the encoded data. The recovering includes detecting at least one of mark and space. The method includes recovering a frame signal from the encoded data, including detecting a pattern associated with the unique encoding pattern based on the detection of the at least one of mark and space. The system for decoding includes a first recover for recovering bit stream from encoded data. The encoded data is generated using a unique encoding pattern for a frame signal in the encoded data. The first recover includes a circuit for detecting at least one of mark and space. The system includes a second recover for recovering a frame signal from the encoded data. The second recover includes a circuit for detecting a pattern associated with the unique encoding pattern based on the detection of the at least one of mark and space.
