1. A method for synchronizing the rendering of content at a plurality of devices, the content having a rendering time, the method comprising:

  • designating one of the devices as a master device and the other devices as slave devices;

    sending to each device content to be rendered at that device synchronized with the content sent to the other devices;

    sending from the master device to the slave devices an indication of when the master device renders content corresponding to a rendering time; and

    after receiving the indication at a slave device, adjusting based on the received indication the rendering of the content at the slave device to account for variation between when the master device and the slave device render content that should be rendered at the same time.
