摘要： A programmable video recorder (PVR) includes a writer application programming interface (API) and a reader API that operate essentially independently to enable the PVR to be networked to multiple reader applications. The writer API creates a backing store and a shared memory mapped file. The backing store stores streamed data in temporary files. The shared memory mapped file stores state information of the backing store files. The reader API receives requests from reader applications to access the stored streamed data. In response to the requests, the reader API permits the reader applications to access the shared memory mapped file to determine where the stored streamed data is located. Upon locating the stored data, the reader API permits the requesting reader applications to access the stored streamed data.

摘要： A computing system that has access to a streamed multimedia sample that is stored on a storage medium applies a zero-based presentation timestamp numbering scheme to the data packets of the multimedia sample, on-the-fly, and after each seek operation. After seeking to a desired starting point, the computing system reads ahead a maximum number of data packets within each media stream of the multimedia sample. A smallest timestamp (normalizing presentation timestamp) is identified and then subtracted from the timestamps of the data packets that are transmitted to the appropriate rendering devices, thereby creating appropriate presentation timestamps for the data packets for synchronizing the playback of the multimedia sample.

摘要： Resource management architectures implemented in computer systems to manage resources are described. In one embodiment, a general architecture includes a resource manager and multiple resource providers that support one or more resource consumers such as a system component or application. Each provider is associated with a resource and acts as the manager for the resource when interfacing with the resource manager. The resource manager arbitrates access to the resources provided by the resource providers on behalf of the consumers. A policy manager sets various policies that are used by the resource manager to allocate resources. A resource consumer creates an “activity” at the resource manager and builds one or more “configurations” that describe various sets of preferred resources required to perform the activity. Each resource consumer can specify one or more configurations for each activity.

摘要： Described is a technology by which a network device uses a document to provide its device description information to a network entity upon connection to a network. From the device description information, the device is provisioned, via a provisioning document by which the device configures itself for interaction with the network. In one example, the documents are XML-based documents each referenced via a uniform resource locator. In one implementation, a discovery agent detects a device broadcasting a discovery message on a network. The discovery agent determines whether the device has been previously provisioned on the network, (and is not being re-provisioned). If so, an assigned network server is directed to take over interaction with the device. If not, the discovery agent provides data to a provisioning agent that provisions the device by providing a device provisioning document by which the device configures itself for interaction with the network.

摘要： Resource management architectures implemented in computer systems to manage resources are described. In one embodiment, a general architecture includes a resource manager and multiple resource providers that support one or more resource consumers such as a system component or application. Each provider is associated with a resource and acts as the manager for the resource when interfacing with the resource manager. The resource manager arbitrates access to the resources provided by the resource providers on behalf of the consumers. A policy manager sets various policies that are used by the resource manager to allocate resources. One policy is a priority-based policy that distinguishes among which applications and/or users have priority over others to use the resources. A resource consumer creates an “activity” at the resource manager and builds one or more “configurations” that describe various sets of preferred resources required to perform the activity. Each resource consumer can specify one or more configurations for each activity. If multiple configurations are specified, the resource consumer can rank them according to preference. This allows the resource consumers to be dynamically changed from one configuration to another as operating conditions change.

摘要： A media server in a Universal Plug and Play (UPnP) network includes a resource sharing service to govern the distribution of resource information regarding resources to rendering devices. In one case, the resource sharing service consults a criterion to determine whether an identified network device is authorized to receive resource information. In another case, the resource sharing service consults another criterion to determine whether a specified individual associated with the media server must consent to the transfer of the resource information in order for the transfer to occur. The resource information may include resource metadata that describes high level information regarding resources, as well as resource content. The media server includes various user interface presentations that allow the media server user to specify shared resources and distribution criteria.
