Open to closed group of pictures conversion in interframe video compression
Methods of converting an open group of pictures (GOP) to a Closed GOP are described that remove backward references to the GOP prior to the GOP undergoing conversion in an Open GOP interframe-encoded video stream. Within the GOP undergoing conversion, bipredictive frames with backward references to the prior GOP are replaced with frames referring only to the I frame of the GOP undergoing conversion, which is flagged as an IDR frame. Consolidation and assembly of video clips that are encoded using Open GOP compression schemes generally result in broken interframe references between GOPs. To address this, existing methods involve significant decoding and re-encoding of edited video sequences.

Multi-factor execution gateway
A user may desire to execute a process in a target environment. However, administrators may want control over processes that haven't been preapproved to prevent the execution of processes that may affect security and compliance within the environment. Implementation of a multi-factor execution gateway may grant the user limited access to execute the process himself at an otherwise restricted, protected, or decoupled environment, while ensuring security and compliance by obtaining approval from the appropriate authorities. For example, a request to execute the process in the environment may be detected, and a fingerprint may be generated based on parameters of the request. A signature for the fingerprint in the form of private key(s) acquired from authorizer(s) based on a level of authorization required for the process may be received to generate a key, and execution of the process may then be allowed at the environment using the key. |

Method and apparatuses for algorithm on QAM coherent optical detection
Blind polarization demultiplexing algorithms based on complex independent component analysis (ICA) by negentropy maximization for quadrature amplitude modulation (QAM) coherent optical systems are disclosed. The polarization demultiplexing is achieved by maximizing the signal's non-Gaussianity measured by the information theoretic quantity of negentropy.
