Abstract
Networked devices are arranged to play content such as audio and video content in synchronization. A synching device receives a packet from an initiating device over a network. The packet may include an identifier of content to play, such as a URI, and an indication of when to play the content. A local clock time to play the content is determined based on a time of a local clock of the first device and the indication of when to play the content. The synching device obtains from a server the content based on the received identifier, and plays the content in synchronization with the initiating device based on a time on the local clock and the local clock time to play the content. In some embodiments, the synching device also adjusts a clock speed of the local clock reference to control rate of playback of the content.
