Abstract: In a first device including a processor and a memory in communication with the processor, the memory includes executable instructions that, when executed by the processor, cause the processor to control the first device to perform functions of receiving, from a second device via a signal connection, a request to project visual content from the second device, the first device being in a locked state to restrict access to the first device that requires valid authentication to transition from the locked state to an unlocked state; determining that the second device has a permission to project the visual content to the first device; receiving, from the second device via the signal connection, data for projecting the visual content to the first device; and based on the received data, displaying, on a display, the visual content.

Abstract: Techniques for projection via a device are described. According to various implementations, techniques described herein enable a locked host device to output data projected from another device while the host device remains in a locked state. In at least some implementations, device context for a host device (locked or unlocked) can be considered in determining whether to broadcast availability to receive projected content.

Abstract: Technologies for selecting a media representation out of a plurality of representations of the same media offered by a media provider wherein the selected representation is a preferred representation and the selecting is based on metadata of the media representations evaluated against scoring criteria.

Abstract: A topology management process is implemented in peer-to-peer content distribution clouds using tracker nodes. Tracker nodes have information about available peers and assist peers in finding other peers to connect to. Various algorithms for use at the tracker nodes are described for selecting which peers to return as potentials for forming connections to. In addition, architectures and algorithms to allow efficient scaling of tracker nodes in peer-to-peer clouds are described.

Abstract: Systems and/or methods (“tools”) are described that enable a digital rights management policy to be associated with digital media having an arbitrary content type or transfer control protocol. In some embodiments, the tools encrypt data segments of a media file and add a descriptor to each of those segments. These descriptors can enable a receiver of the encrypted media file to decrypt the file and consume it according to the correct digital rights management policy.

Abstract: A method is provided for allowing Universal Plug and Play (UPnP) technology to be used over the Internet or other wide area communications networks. In one illustrative example, a first UPnP-enabled device is to provide a UPnP service such as streaming media to various users over the Internet. The first UPnP-enabled device provides an on-line identity provider such as Windows Live or the like with user IDs of those users who are authorized to access the first UPnP-enabled device from a remote location. When a user wishes to receive the UPnP service from the first UPnP-enabled device, the user logs in to the on-line identity provider using his user ID and receives from the on-line provider an IP address associated with the first UPnP-enabled device. The user's media player or other application constructs a URL from the IP address and contacts the UPnP-enabled device at that URL. The UPnP-enabled device provides the user with a list of media libraries that are available on it.

Abstract: Embedded within at least some Real-Time Control Protocol (RTCP) messages sent from a media content source to a recipient is a session description message that describes a media presentation being streamed to the recipient. The session description message can be associated, for example, with one of a plurality of pieces of media content in a play list of media content being streamed from the device to the recipient. In accordance with certain aspects, an RTCP message that embeds a session description message includes at least three fields: a first field containing data identifying the RTCP message as being a type that embeds a session description message; a second field containing data that is the session description message for a media presentation; and a third field containing data identifying a length of the RTCP message, generated by summing the length of the first, second, and third fields.

Abstract: Automatically recovering from broken network connections in streaming media scenarios. Server software executing on the server communicates with client software executing on the client during the streaming media session. If the streaming media session is interrupted, the server software and the client software exchange messages to associate the client with a client state stored by the server and to re-synchronize playback of the content.

Abstract: The invention describes a control node for a content distribution network and a method of automatically verifying content distributed over a network at a node in the network. In the method, a content description is received which comprises a content identifier, a publisher identifier, publisher authorization information and content checking information. The integrity and validity of this information are checked and if both the checks are passed, the content description is stored.
