A system for dynamically determining and introducing time delay values for synchronizing different data signals. For transmitting the data signals, encoding time delay is measured in one encoder, a target encoder time delay value is determined, and the target encoder time delay value is utilized in another encoder to delay transmission of one data signal relative to the transmission of the other data signal. When encoded data signals are received and processed for presentation, the time required to decode a first data signal in a first decoder is measured, a target decoder time delay value is determined based on the time required to decode the first data signal, and the target decoder time delay value is utilized to delay presentation of a second data signal relative to the presentation of the first data signal.
