Abstract
There is provided a content playback system in which a first playback device and a second playback device that can receive and play back content from a server device are connected through a network. When the first playback device, while receiving and playing back the content from the server device, receives a switching command for causing the content that is currently being played back to be played back on the second playback device, the first playback device transmits through the network to the second playback device playback information that includes attribute information and an elapsed playback time for the content that is currently being played back. When the second playback device receives the playback information from the first playback device, the second playback device, based on the playback information, receives from the server device and plays back data that starts from the elapsed playback time for the content.
