Abstract
A portable video delivery device includes data storage, a secure processor, and a wireless network interface that acts as an access point for a secure personal wireless network. Transcoded media files are stored in the data storage so that the portable device maintains a library of stored media programs that can be carried along with the user during commuting, travel and/or other activities. To playback the stored programming, other media player devices use the personal wireless network to securely connect to the portable device and to obtain previously-transcoded content from the data storage of the device.
Claims18
A portable device to deliver video content to at least one media player device, the portable device comprising:
- a data interface to a wide area network;
- a transcoder configured to receive video content and to transcode the received video content into a format that is suitable for delivery to the at least one media player device over a personal wireless network that is separate from the wide area network;
- a data storage configured to store the transcoded video content;
- a wireless network interface configured to provide a wireless access point to the personal wireless network that is separate from the wide area network;
- and
- a processor configured to receive a digital credential identifying the at least one media player device via the data interface, wherein the digital credential is issued by an authenticator service accessible via a wide area network that is not reachable via the personal wireless network, to store the digital credential received from the authenticator service, to subsequently issue one or more addresses on the personal wireless network to the at least one media player device, to receive subsequent connection requests comprising digital credentials from the at least one media player device via the personal wireless network while the portable device is offline from the wide area network using the address on the personal wireless network that was issued by the portable device and, in response to the subsequent connection requests, to perform an offline authentication of the digital credentials received from the at least one media player while the portable video storage is offline from the wide area network and to deliver the transcoded video content to the at least one media player device via the personal wireless network that is separate from the wide area network if the digital credentials received from the at least one media player device via the personal wireless network match the digital credentials previously received from the authenticator service via the wide area network, and to otherwise not deliver the transcoded video content to the at least one media player device via the personal wireless network.

A method executable by a portable video storage device to deliver video content to a media player, the method comprising:
- receiving a digital credential from an authentication service at the portable video storage device via a first digital network, wherein the digital credential identifies the media player;
- storing transcoded video content in a data storage of the portable video storage device;
- subsequently providing a wireless access point to a personal wireless network by the portable video storage device, wherein the personal wireless network is separate from the first digital network and available while the portable video storage device is offline from the first digital network;
- receiving a connection request from the media player at the portable video storage device via the personal wireless network that is separate from the wide area network, wherein the connection request from the media player comprises the digital credential previously issued by the authentication service identifying the media player;
- issuing an address on the personal wireless network to the media player device if the media player device is authorized to receive the transcoded video content, and otherwise not issuing an address on the personal wireless network to the media player device;
- and
- performing an offline authentication of the digital credential received from the media player while the first digital network is unavailable to the portable video storage device, and, if the digital credential received from the media player via the personal wireless network while the portable video storage device is offline from the first digital network matches the digital credential previously received from the authentication service via the first digital network and previously stored by the portable video storage device, the portable video storage device providing the transcoded video content from the portable video storage device to the media player device via the personal wireless network that is separate from the first digital network, and otherwise not providing the transcoded video content via the personal wireless network.

A portable device to deliver video streams to at least one media player device, the portable device comprising:
- a data interface to a wide area network;
- a data storage configured to store video content that is transcoded in a video streaming format;
- a wireless network interface configured to provide a wireless access point to a personal wireless network that is separate from the wide area network;
- and
- a processor configured to receive a digital credential identifying the at least one media player device via the data interface, wherein the digital credential is issued by an authenticator service accessible via the wide area network separate from the personal wireless network, to store the digital credential received from the authenticator service, to receive subsequent connection requests comprising digital credentials from the at least one media player device via the personal wireless network that is separate from the wide area network, and performing an offline authentication of the digital credentials received from the at least one media player device while the portable device is offline from the wide area network to verify that the at least one media player device is authorized to receive the transcoded video content, wherein the offline authentication comprises comparing the digital credentials received from the at least one media player via the personal wireless network to the digital credentials previously received from the authenticator service via the wide area network, and, if the at least one media player device is authorized, to assign an address on the personal wireless network to the at least one media player device and to deliver the transcoded video content to the at least one media player device via the personal wireless network while the portable device is offline from the wide area network, and otherwise not assigning the address on the personal wireless network to the at least one media player device and not delivering the transcoded video content to the at least one media player device via the personal wireless network.
