Abstract
A method and apparatus for combining a plurality of 8B/10B encoded DVB-ASI input streams into an aggregate output data stream allows a receiving device to synchronize to the aggregate output data stream by mapping a synchronization character to a unique character if the synchronization character occurs in a first timeslot of the aggregate output data stream. This unique character allows a receiving device to synchronize to the aggregate output data stream. If the synchronization character occurs in a timeslot other than the first timeslot, the synchronization character is mapped to another special character that denotes that no data is present in the timeslot. In addition, if the synchronization character occurs in a timeslot after the last timeslot in which data may be placed in the aggregate output data stream, the synchronization character can be mapped to yet another special character denoting that no data is available in the timeslot.
