Abstract:
System for dynamic arbitration of a shared resource on a device. A method is provided for arbitrating the allocation of a device resource on a device. The method comprises receiving a request from a requesting application that requests allocation of the device resource, and determining that the device resource is owned by an owning application. The method also comprises associating owner information with requester information to form an arbitration request, wherein the owner information comprises information about the owning application and the requester information comprises information about the requesting application. The method also comprises arbitrating the arbitration request to produce an arbitration decision that indicates whether or not the device resource should be allocated to the requesting application, and allocating the device resource based on the arbitration decision.
Abstract:
Methods and devices provide for creating, managing, modifying, and/or enforcing flexible digital rights management license policies for protecting games, media, data, or other software with a time-based license. Embodiments are especially directed toward situations in which a source of time is unavailable, untrustworthy, or unreliable. Licenses are defined by a small number of parameters. Parameter values may be defined by and included with protected content or applications. The parameter values may be chosen to define and enforce a desired level of compromise between usability and security characteristics.

Abstract:
System for application priority based on device operating mode. A method is provided for allocating a top visible resource on a device. The method includes receiving a request requesting allocation of the top visible resource to a requesting application, and determining that the top visible resource is allocated to an owning application. The method also includes associating owner information with requester information to form an arbitration request. The method also includes arbitrating the arbitration request to produce an arbitration decision that indicates that the top visible resource is to be allocated to the requesting application if the owner information indicates that the owning application is privileged and an identifier that identifies the requesting application is contained in a relinquish list associated with the owner information.
Abstract:
A system for dynamic arbitration of a shared resource on a device (300). As the applications (322, 324, 326) execute on the device (300), they submit requests to the sound manager (318) and the camera manager (320) to access the associated device resources. The requests are processed to allocate each of the sound resource (306) and the camera resource (308) to selected applications. In the case where a device resource is currently unallocated, that device resource may be easily allocated to a requesting application. Associating owner information with requester information to form an arbitration request, wherein the owner information comprises information about the owning application and the requester information comprises information about the requesting application.
