Abstract

Media content associated with a playlist is provided for remote access over a packet-based network. According to an example embodiment of the present invention, a host server provides access to a user-defined playlist depicting media content available from user'"'"'s media content source (e.g., at a registered user'"'"'s PC). User-defined playlists and associated media content are managed to facilitate access to media in accordance with characteristics of the media content and/or playlist such as format and bitrate, and as may be related to an intended playback use of the playlist. Media content for the playlists is stored in a network storage device for remote access, with the storage managed to facilitate remote access in appropriate formats, with selective cross-referencing among playlists for different playlist types, content format and content bandwidth.

Claims

1. A system comprising:

a network-based storage that

identifies at least one media content title under at least two playlists and at least two formats of media content files for the at least one media content title based, at least in part, on a cross-referencing file structure, and

determines to store media content and playlist data based, at least in part, on the identification of the at least one media content title and the at least two formats; and

a host server that

in response to a request for a playlist, identifies at least one media content file associated with the playlist based, at least in part, on the cross-referencing file structure;

facilitates delivery of the at least one media content file from the network-based storage to a remote playback device based, at least in part, on the identification of the at least one media content file.

2. The system of claim 1, further comprising:

a registered-user packet-based media arrangement configured to send playlist-based media content to the network-based storage over a data network.

3. The system of claim 2, wherein at least one of the host server and the registered user packet-based media arrangement selectively configures media content for playback at a remote playback device by configuring the media content to a bitrate that is different than a bitrate of the media content in a first configuration as stored at the registered-user packet-based media arrangement.

4. The system of claim 2, wherein at least one of the host server and the registered user packet-based media arrangement selectively configure media content for playback at a remote playback device by configuring the media content to a format that is different than a format of the media content in a first configuration as stored at the registered-user packet-based media arrangement.

5. The system of claim 2, wherein the host server responds to playlist requests by authenticating the requests and, in response to a request being authenticated, communicating with the network-based storage to facilitate the streaming of media content for media content titles in the requested playlist to a remote playback device, using the file structure to identify media content files to be delivered.

6. The system of claim 2, wherein the host server facilitates delivery of the media content files from the network-based storage to a remote playback device by communicating with the network-based storage over the packet-based network.

7. The system of claim 2, wherein the host server facilitates delivery of the media content files from the network-based storage by controlling the network based storage to deliver the media content files.

8. The system of claim 2, wherein

the registered-user packet-based media arrangement establishes a communications link with the host server over the packet-based network, and

the host server controls the registered-user packet-based media arrangement to send the playlist-based media content to the network-based storage.

9. The system of claim 2, wherein the registered-user packet-based media arrangement accesses the packet-based network to establish communications with the host server over the packet-based network, wherein the host server facilitates said sending of playlist-based media content over the packet-based network via the communications established by the registered-user packet-based media arrangement.

10. The system of claim 2, wherein the host server administratively controls the registered-user packet-based media arrangement to send playlist-based media content to the network-based storage over the packet-based network.

11. The system of claim 2, wherein the registered-user packet-based media arrangement includes a personal computer connected to the Internet via a modem, and wherein the host server administratively controls the personal computer, using communications established with the host server by the personal computer, to send playlist-based media content to the network-based storage over the data network.

12. A method comprising:
