摘要
A method is provided to synchronize Adaptive Bit Rate (ABR) video streams created from a single baseband video signal that is distributed through multiple different length coax transmission lines to different video encoders. The method inserts a marker in the baseband signal of the Serial Digital Interface (SDI). The baseband signal is then split with the inserted regular markers and distributed to encoders over different length coax transmission lines. Synchronizing the baseband video can then be performed using baseband receivers provided with the different encoders. A marker can be proprietary or can be based on timing standards for SDI such as vertical interval time code (VITC).
