摘要： A playback apparatus can communicate with a second server, which temporarily stores in a first buffer compressed digital data that is received from a first server, and when the first buffer has stored a first data volume of the compressed digital data, which is a volume that is sufficient for a decoding of the compressed digital data, reads the compressed digital data out of the first buffer and decodes it into decompressed digital data. The playback apparatus includes a second buffer, which temporarily stores the decompressed digital data that is received from the second server; a D/A conversion portion (340), which converts into analog data the decompressed digital data that is temporarily stored in the second buffer; and a notification information generation portion (370), which generates notification information that conveys storage statuses of the first buffer and the second buffer.

摘要： In a playback apparatus, when a transmission finished notification for kth decompressed digital data is received via a communication portion, a control portion detects a silence start position in the kth decompressed digital data that is stored in the first buffer, transfers a section of the kth decompressed digital data that is before the silence start position to the second buffer, temporarily stores (k+1)th decompressed digital data that is received via the communication portion in the first buffer following the transfer of the section of the kth decompressed digital data, detects a silence end position in the (k+1)th decompressed digital data that is stored in the first buffer, and transfers a section of the (k+1)th decompressed digital data that is after the silence end position to the second buffer.

摘要： 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.
