Abstract: Method and apparatus are disclosed for synchronizing multimedia in asynchronous networks. In this invention, clock domains are first reduced to separate hardware clock correction circuits at the separate endpoints of an asynchronous network. At each end of the network node, the controllable input device such as a video device is synchronized to the non-controllable output device such as a set top box to prevent unknown or poor-quality alterations by the output device. Output device timestamp packets are regularly sent to the input device, which then adjusts its clock accordingly. The exchange of packets between input devices over the asynchronous network is then subjected to a software-based scheme to effectively synchronize these devices.
