a method for transmitting synchronization information with data , which data corresponds to a sequence of samples representative of a signal , includes detecting the occurrence of two consecutive equivalent samples and inserting a synchronization pattern for the second - occurring sample prior to transmission . at a receiving end , the incoming signal is monitored to detect the presence of the sync pattern and hold the value of the receiver output at the value of the immediately previous received sample . in this manner , the signal is reconstructed without degradation , and byte synchronization information is sent without any bandwidth loss .
