Verifying and encouraging asset consumption in a communications network
Systems and methods presented herein generally provide for the compensation of asset providers and/or communications network providers for the non-consumption of assets provided with programming. In this regard, when users elect not to consume the assets associated with the programming, the asset provider loses the opportunity to present their assets to such non-consuming users and is thereby injured in relation to the price they have paid for the delivery of their assets. In one arrangement, a reporting module at a customer device is operative to identify when a user skips an asset and report that skip event to the network. This information may then be utilized to adjust the bill of the asset provider and/or to bill the user associated with the skip event. |

System and method of speaker reidentification in a multiple camera setting conference room
In a multi-camera videoconferencing configuration, the locations of each camera are known. By referencing a known object visible to each camera, a 3D coordinate system is developed, with the position and angle of each camera being associated with that 3D coordinate system. The locations of the conference participants in the 3D coordinate system are determined for each camera. Sound source localization (SSL) from one camera, generally a central camera, is used to determine the speaker. The pose of the speaker is then determined. From the pose and the known locations of the cameras, the camera with the best frontal view of the speaker is determined. The 3D coordinates of the speaker are then used to direct the determined camera to frame the speaker. If the face of the speaker is not sufficiently visible, the next best camera view is determined, and the speaker framed from that camera view. |

Network storage backup using distributed media agents
Certain embodiments disclosed herein reduce or eliminate a communication bottleneck at the storage manager by reducing communication with the storage manager while maintaining functionality of an information management system. In some implementations, a client obtains information for enabling a secondary storage job (e.g., a backup or restore) from a storage manager and stores the information (which may be referred to as job metadata) in a local cache. The client may then reuse the job metadata for multiple storage jobs reducing the frequency of communication with the storage manager. When a configuration of the information management system changes, or the availability of resources changes, the storage manager can push updates to the job metadata to the clients. Further, a client can periodically request updated job metadata from the storage manager ensuring that the client does not rely on out-of-date job metadata. |

Classical implementation of quantum entanglement in datacenter network design
Quantum mechanics provides several features useful for datacenter networking. The no cloning theorem, which states that it is impossible to mate a duplicate of an arbitrary, unknown quantum state, can be used to detect eavesdroppers. Entanglement allows two parties to have common knowledge of a shared state. These properties are being used today for quantum key exchange and quantum computing, but they are currently too expensive for general use. Fortunately, we can use classical mechanisms to get a close enough approximation of these quantum properties to solve some important problems in distributed computing. Nothing we describe here is quantum mechanical. Rather, we show that it is possible to use classical mechanisms to emulate some properties of quantum mechanics, which enable us to address interesting problems in distributed computing. The engineering insight, is that we can get closer to achieving these properties than might be expected through conventional thinking. The key to obtaining the properties we desire is to make the inherently asynchronous system temporarily locally synchronous for the operations we need. In this patent, we describe how to classically emulate the parts of the no cloning theorem and entanglement that we need for datacenter networking. We then demonstrate how those approximations to quantum behavior can be used to solve important problems in distributed computing, such as ‘exactly-once’ semantics in an environment where failures occur and can be healed without applications needing to know. |
