Disclosed is a system and application for digital media that allows users to share a media playlist and synchronize playing for all connected users. The user browses their device for media files to create a playlist, and then hosts the playlist over an existing local area network or creates a Wi-Fi hotspot. The playlist may be encrypted to provide a form of digital rights management. Other users are then prompted to download the playlist and send the host a calculated playback delay. Once all users have completed downloading the playlist the hosting user is prompted to press play, pushing timing information that takes into account the largest delay to all connected users via the active local area network, resulting in all devices playing the media in synchronicity for the duration of the playlist. Additional users may opt in during playback and use the timing information to synchronize their devices' playback.

Data are maintained in a distributed computing system that describe a graph. The graph represents relationships among items. The graph has a plurality of vertices that represent the items and a plurality of edges connecting the plurality of vertices. At least one vertex of the plurality of vertices includes a set of label values indicating the at least one vertex's strength of association with a label from a set of labels. The set of labels describe possible characteristics of an item represented by the at least one vertex. At least one edge of the plurality of edges includes a set of label weights for influencing label values that traverse the at least one edge. A label propagation algorithm is executed for a plurality of the vertices in the graph in parallel for a series of synchronized iterations to propagate labels through the graph.

The invention includes; A method for a companion device to receive current state information from a primary device comprising: (a) said companion device receiving from said primary device based upon a subscription request from said companion device to said primary device, said current state information including at least one of: (i) a media playback state including at least one of: (1) playing; (2) paused; (3) stopped; (4) fast forward; (5) fast backward; (6) buffering; (7) unknown; (8) reserved; (ii) a media playback speed including at least one of: (1) current speed of media state relative to normal speed; (2) current speed at which a media timeline is moving forward; (3) current speed at which a media timeline is moving backward.

A first request for content from a client device is received. The first request includes a resource locator provided by an authorizing data service to authorize the client device to obtain the requested content. The resource locator includes a first digital signature associated with authorization of the client device to access the requested content, and a second digital signature associated with authorization of delivery of the requested content for access by the client device. An occurrence of an event is identified that indicates a change in the delivery of the requested content to the client device. A third digital signature associated with a changed delivery of the requested content is generated. A new resource locator is provided to the client device that includes the first digital signature and the third digital signature.

A method for managing licenses for a service application across a plurality of interconnected industrial sectors. The method includes: selecting a delegation policy; deploying a local virtual license manager in one of the two industrial sectors, and sending a license authorizing the local virtual license manager to use the service application, in particular for executing a command of a cyber-physical system.

An information processing apparatus includes a processor and memory. The memory stores information on multiple image forming apparatuses capable of making an image forming request. The processor is configured to: install license-managed software; select an image forming apparatus serving as a license management server of the software from the multiple image forming apparatuses; and set the selected image forming apparatus as a license management server.

A system and process for converting a digital media file into a digital token is disclosed. The embodiments modify a digital media file so that a set of rules are attached to the digital media file creating a digital token, which can be used to persist the digital media file through a network. In an exemplary embodiment, the network is a distributed ledger or blockchain based network that securely tracks distribution of the digital media file. The digital token may have a value added to it or value may intrinsically exist as the digital token is persisted through the network. The value associated with distribution of the digital media file may be used to reward the owner of the digital media file, distributors of the token, or as an incentive program for commercial transactions and non-commercial transactions.
