Protocole Diretta

[floyer]

Il faudrait poser la question à Yu. Je sais qu'en MAO, on a souvent si ce n'est exclusivement des logiciels qui ne supportent qu'une horloge de référence. (Des exceptions avec l'aggrégation d'interface audio sur MacOS) Si le protocole Diretta synchronise les équipements... distribuer une heure très précise ne sert pas à grand chose (juste avoir un DAC très bien cadencé).

Retour à la bible... (la mise en gras venant de moi)

The Host operates in synchronization with the Target to average processing by the Target. Packets are transmitted as often as possible at constant short intervals in order to average processing.The transmission is controlled by forecasting Target buffers.
In this way, fluctuations in power consumption of a player as the Target is averaged as much as possible.

We don' t say that this method is definitely better than other transmission systems. But, we would like to propose one different approach.
It is similar to USB synchronization, but the Target doesnt change speed because the Host synchronizes.There is no buffer/flow control like USB ansynchronization. Completely insulated connection can be used and fibers and other cables can be adopted because it is Ethernet.No complicated processing like UPnP file range requests is required. No complicated processing to synchronize many devices like AES67 is required, either.

Donc Diretta assure la synchronisation. On note la référence à AES67 qui s'appuie sur PTP.
