摘要： A computing system, which is in communication with a multimedia source and that includes at least one application for processing multimedia content from the multimedia source, includes an Application Programming Interface (API) for obtaining basic multimedia information that may be required by applications to process the multimedia content. By doing this, the invention enables multimedia application(s) to easily obtain the basic information from the API in a predetermined and standard manner, without having to obtain the information directly from the multimedia source, thereby reducing the functionality that has to be programmed directly into the application(s) for obtaining the basic information, and thereby reducing the cost, time, and resources that are required for creating the multimedia application(s).

摘要： Systems and methods for midstream determination of varying available bandwidth for streaming content between two network entities are described. During content streaming, a client requests a server to surge the content transmission rate. One or more bandwidth measurements are taken during the surge to determine if the increased transmission rate can be adequately managed. If the increased transmission rate can be adequately managed, the client may request the server to transmit remaining content at a transmission rate that is not greater than the increased, or surged, transmission rate. In a multi-bitrate file scenario, the surge rate may be higher than the rate of the fastest useable stream. In such a case, the fastest useable stream is selected. If the increased transmission rate is not suitable for future transmission, then the rate may remain at the original transmission rate.

摘要： A list of computing components to be disabled can be distributed through a computer readable medium to computing devices. A process on these computing devices can read the list and disable listed components. The components can be permanently disabled, or disabled for a limited purpose. A list or list update may be provided with a digital media object that specifies a more or less stringent revocation policy for that object. A media object may also specify a maximum age for the list. This allows owners of digital media to control the stringency of media protection for their property. The process that accesses the list may prompt updates to the list, informing users of component disabling, and prompt replacement of disabled components. Finally, the invention provides techniques for securely transmitting and storing the list to protect it from alteration by unauthorized entities.

摘要： Media processing methods, systems and application program interfaces (APIs) are described. In but one embodiment, a media engine component, also referred to as a media engine, provides a simple and unified way of rendering media from an origin to a destination of choice without requiring intimate knowledge about the underlying components, their connectivity and management. Clients of the media engine need not worry about how to render the particular media, but rather can simply focus on what media to render and where to render the media. In at least one embodiment, a media session is provided and is encapsulated by the media engine and provides a mechanism by which additional components are made transparent to the application and, in at least some embodiment, the media engine. In some embodiments, the media engine and media session provide a simple API for building, configuring, and manipulating a pipeline of components (e.g. media sources, transforms, and sinks) for media flow control between an origin and one or more destinations.

摘要： Embodiments related to the establishment of a relationship between wireless devices are disclosed. In one disclosed embodiment, a wireless device includes an image capture device, a wireless transmitter and receiver, a logic subsystem, and memory comprising instructions executable by the logic subsystem to capture a first image via the image capture device, identify authentication features of the first image, and receive authentication data from a remote media device via the wireless receiver that comprises authentication features of a second image. The instruction further cause the logic subsystem to compare the authentication features of the second image to the authentication features of the first image to establish a trusted relationship with the remote media device if the authentication features of the second image exhibit a pre-determined relationship to the authentication features of the first image.
