Delay time fluctuation suppression device in IP line for audio transmission -AES/EBU audio synchronization unit-

Abstract

W hile audio signa l is transferred via IP network, delay time of received audio is varied and fluctuated by IP Codec and network equipment. We have successfully developed a new synchronizing unit which lets those delay time constant by inserting unique signal into transmitt ing audio band. This unit can make it possible to utilize IP networks for transmitting audio signal from studio to more than two transmitters which compose SFN (single Frequency Network) of AM and FM Radio broadcasting.
