In one embodiment, a home theater at a subscriber premises includes multiple home theater components, which include multiple audio playback components and a video playback component. Each home theater component is enabled to receive data from and send data to a virtualized home theater service via a WAN.

The virtualized home theater service also provides absolute playback timestamps for the media content streams. The absolute playback timestamps are preferably provided to substantially synchronize playback of the media content streams by the home theater components as well as to accommodate for network delays.
