  • Patent number: 8973139
    Abstract: A method, computer readable medium and apparatus for detecting an altered application are disclosed. Network traffic data is obtained for a number of endpoint devices to determine a network traffic signature for a first application. The signature comprises a set of flows within a time window. Network traffic data is monitored to determine a network traffic signature for a second application. The signature for the second application comprises the network traffic signature of the first application plus a flow to an additional address. The method determines a ratio of endpoint devices having network traffic data that matches the signature for the second application as compared to a percentage of endpoint devices having network traffic data that matches the signature for the first application. When the percentage satisfies a threshold, the method determines that the second application is the altered application comprising an altered version of the first application.

  • Patent number: 8972728
    Abstract: Portable storage devices and methods for remotely managing such portable storage devices are disclosed. For example, a method receives a request from an endpoint device to send a command to a portable storage device. The method then authenticates the endpoint device that has sent the request. The method then transmits the command wirelessly to the portable storage device. Similarly, a portable storage device includes a processor and a computer-readable medium in communication with the processor, the computer-readable medium to store instructions. The instructions, when executed by the processor, cause the processor to perform operations that include: wirelessly receiving a command related to an access of a memory of the portable storage device, verifying an authenticity of the command and executing the command when the authenticity of the command is verified.

  • Publication number: 20150054960
    Abstract: A digital camera accesses, processes and displays a combination image composed of visible light and near non-visible (“NNV”) light. A method can include accessing, by a digital camera, raw data having first information associated with a first electromagnetic spectrum range and second information associated with a second electromagnetic spectrum range. The first electromagnetic spectrum range is substantially within the visible spectrum and the second electromagnetic spectrum range is substantially within the NNV spectrum. The method can also include optimizing the raw data for the visible spectrum, thereby generating a first visual image representation, and optimizing the raw data for the NNV spectrum, thereby generating a second visual image representation. The method can also include combining the first visual image representation and the second visual image representation to generate a combination image. The digital camera can then initiate the display of the combination image.

  • Publication number: 20150058004
    Abstract: Disclosed herein are systems, methods, and computer-readable storage media for detecting voice activity in a media signal in an augmented, multi-tier classifier architecture. A system configured to practice the method can receive, from a first classifier, a first voice activity indicator detected in a first modality for a human subject. Then, the system can receive, from a second classifier, a second voice activity indicator detected in a second modality for the human subject, wherein the first voice activity indicator and the second voice activity indicators are based on the human subject at a same time, and wherein the first modality and the second modality are different. The system can concatenate, via a third classifier, the first voice activity indicator and the second voice activity indicator with original features of the human subject, to yield a classifier output, and determine voice activity based on the classifier output.

  • Patent number: 8966555
    Abstract: A method and system for performance monitoring of a multimedia content distribution network (MCDN) includes a probe device configured to capture input and output data with respect to a network terminal device at an MCDN client premises. The input data, representing network data sent to the MCDN client for display, may be buffered along with the output data, representing audio and video data generated using the input data. When an anomaly event, such as a display error, occurs, the probe device may record the buffered input and output data, including data acquired prior to the anomaly event. The input and output data may be analyzed to determine a source or origin of the anomaly event. The probe device may also certify that the MCDN and/or the network terminal device was operating normally.

  • Patent number: 8965999
    Abstract: Distribution schemes for subscriber-created content are described. Subscribers create and upload content for distribution to communities of recipients. The recipients join the communities in response to invitations from the subscribers. When connections to devices associated with the recipients are detected, any content due for delivery to the recipients is distributed. Systems supporting these distribution schemes may include content distribution modules that receive the content from the subscribers, and that provide corresponding content notifications. Content storage modules store the uploaded subscriber content. In response to the content notifications, notification modules notify the recipients that the content is available. Presence modules detect the connections to the devices, and provide corresponding device notifications. In response to the device notifications, device management modules provide recipient notifications, which associate recipients with the detected devices.

  • Patent number: 8966553
    Abstract: A video-on-demand (VOD) server in an Internet protocol television (IPTV) network with a network of set-top boxes includes IPTV operational data and an analysis module that selects a content item. The VOD server divides the content item into sequential chunks, divides the chunks into stripes, pre-populates set-top boxes in a peering network with at least one stripe from each chunk, receives a request for the content item, and directs each set-top box to sequentially stream its stripes. A method includes selecting a content item based upon IPTV operational data, dividing the content item into sequential chunks, dividing the chunks into stripes, pre-populating set-top boxes in a peering network with at least one stripe from each chunk, receiving a request for the content item, and directing each set-top box to sequentially stream its stripes.

  • Patent number: 8965768
    Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for detecting and correcting abnormal stress patterns in unit-selection speech synthesis. A system practicing the method detects incorrect stress patterns in selected acoustic units representing speech to be synthesized, and corrects the incorrect stress patterns in the selected acoustic units to yield corrected stress patterns. The system can further synthesize speech based on the corrected stress patterns. In one aspect, the system also classifies the incorrect stress patterns using a machine learning algorithm such as a classification and regression tree, adaptive boosting, support vector machine, and maximum entropy. In this way a text-to-speech unit selection speech synthesizer can produce more natural sounding speech with suitable stress patterns regardless of the stress of units in a unit selection database.

  • Patent number: 8965767
    Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for generating a synthetic voice. A system configured to practice the method combines a first database of a first text-to-speech voice and a second database of a second text-to-speech voice to generate a combined database, selects from the combined database, based on a policy, voice units of a phonetic category for the synthetic voice to yield selected voice units, and synthesizes speech based on the selected voice units. The system can synthesize speech without parameterizing the first text-to-speech voice and the second text-to-speech voice. A policy can define, for a particular phonetic category, from which text-to-speech voice to select voice units. The combined database can include multiple text-to-speech voices from different speakers. The combined database can include voices of a single speaker speaking in different styles. The combined database can include voices of different languages.
