SERVER DEVICE FOR MEDIA, METHOD FOR CONTROLLING SERVER FOR MEDIA, AND PROGRAM
First Claim
1. A server device for media equipped with an internal storage device for storing digital contents, wherein the server device for media responds to a data transmission request from a network player by stream-delivering corresponding data in corresponding digital contents from the internal storage device to the network player during connection to a network, the server device for media comprising:
- a transfer control unit adapted to transfer and storing part of held digital contents in the internal storage device to a network storage device, wherein the network storage device is connected to the network and is capable of storing data;
a list information transmission unit adapted to respond to a list presentation request for the held digital contents of the server device for media from the network player by transmitting list information to the network player, wherein the list information makes the digital contents left in the internal storage device and the digital contents transferred from the internal storage device to the network storage device and stored in the network storage device as the held digital contents of the internal storage device;
a search unit adapted to respond to a data transmission request for the held digital contents from the network player by searching for a location where the held digital contents are currently stored; and
a digital contents data transmission processing unit adapted to allow the corresponding data to be stream-delivered from the network storage device to the network player, if the result of search shows the network storage device.

Abstract
Transfer control means (41) transfers part of held digital contents in an internal storage device (51) to a network storage device (57). List information presentation means (42) returns list information which makes the digital contents stored in the internal storage device (51) and the network storage device (57) as the held digital contents in response to a list presentation request for the held digital contents. Upon reception of a data transmission request, search means (43) searches where the held digital contents are currently stored. If the result of the search shows the network storage device (57), content data transmission processing means (44) allows the stream-delivery of the data from the network storage device (57) to a network player (56). There is provided a server device for media (40) capable of maintaining the convenience of playback in a network player, while properly dealing with the large total size of held digital contents.

8. A method for controlling a server device for media which is equipped with an internal storage device for storing digital contents, and responds to a data transmission request from a network player by stream-delivering corresponding data in corresponding digital contents from the internal storage device to the network player during connection to the network, the method comprising the steps of:
-
transferring and storing part of held digital contents in the internal storage device to a network storage device, wherein the network storage device is connected to the network and is capable of storing data; responding to a list presentation request for the held digital contents of the server device for media from the network player by transmitting list information to the network player, wherein the list information makes the digital contents left in the internal storage device and the digital contents transferred from the internal storage device to the network storage device and stored in the network storage device as the held digital contents of the internal storage device; responding to a data transmission request for the held digital contents from the network player by searching for a location where the held digital contents are currently stored; and allowing the corresponding data to be stream-delivered from the network storage device to the network player, if the result of search shows the network storage device.
