  • Publication number: 20140282775
    Abstract: An internet protocol multicast provider is disclosed, which includes a bootstrap code component, a transcoder generator component, a content module and a packetizing module. The bootstrap code component can generate a bootstrap code. The transcoder generator component can generate a transcoder module. The content module can generate content in a first format. The packetizing module can generate internet protocol multicast packets, based on the bootstrap code, the transcoder module and the content. The bootstrap code can determine a second format for which an internet protocol multicast receiver can decode and render the content. The transcoder module can instruct the internet protocol multicast receiver to play the content when the first format is the second format. The transcoder module can instruct the internet protocol multicast receiver to transcode the content from the first format to the second format when the first format is not the second format.

  • Publication number: 20140280781
    Abstract: An adaptive bit rate system uses adaptive streaming to deliver content to client devices capable of adaptive bit rate streaming. Enhancing or generating compound manifest files for delivery to clients in an adaptive streaming environment permits a direct acquisition of media segments to services not currently being viewed. For example, the compound playlist can be designed to offer direct access to neighboring channels or other services in the same genre. These novel enhancements to the manifest files may reduce channel change times as well as the efficient delivery of manifest files.

  • Publication number: 20140280529
    Abstract: Systems, methods, and devices for determining contexts and determining associated emotion profiles using information received from multiple emotion sensor enabled electronic devices, are disclosed. Contexts can be defined by a description of spatial and/or temporal components. Such contexts can be arbitrarily defined using semantically meaningful and absolute descriptions of times and locations. Emotion sensor data is associated with or includes context data that describes the circumstances under which the data was determined. The emotion sensor data can include emotion sensor readings that are implicit indications of an emotion for the context. The sensor data can also include user reported data with explicit descriptors of an emotion for the context. The emotion sensor data can be filtered by context data according a selected context. The filtered sensor data can then be analyzed to determine an emotion profile for the context that can be output to one or more users or entities.

  • Publication number: 20140269314
    Abstract: Combining network and client based adaptive streaming approaches enable a distributed and adaptive resource management system for carrier quality video transmission over cable Wi-Fi systems. The adaptive resource management over cable Wi-Fi heterogeneous networks includes a network based approach using client based feedback. The resource management of a video stream is performed on a service provider's network, for example in a cable modem termination system, by evaluating a margin and a fairness index. In embodiments, the rate of a video stream to a requesting client is adjusted and, in embodiments, the rate of a video stream for non-requesting clients is adjusted. Embodiments include mechanisms for call admission control and adaptive streaming based on adjustable resource margins and fairness indices for DOCSIS and Wi-Fi hetnet systems.

  • Patent number: 8837723
    Abstract: In a downloadable conditional access system (DCAS), preferably all DCAS-specific code is implemented in a configurable secure (CS) processor that is in communication with the host processor. Preferably, no DCAS-specific code is executed in the host processor. The host processor delivers commands to the CS processor, which the CS processor performs to configure itself in accordance with the particular DCAS encryption scheme used by the DCAS. Once configured, the CS processor executes a DCAS software module that has been downloaded to the CS processor, which looks for the corresponding EMMs and ECMs, processes them to obtain the CW, and then uses the CW to decrypt the content stream.

  • Patent number: 8826346
    Abstract: A method of operating an IP client device for presentation of video content to a viewer includes the step of transmitting a trickplay request to a server. The client device receives from the server a manifest that references at least first and second consecutive video content fragments. The first fragment contains a sequence of N1 frames and the second fragment contains a sequence of N2 frames, and defines a set of M1 frames of the first fragment, where M1 is less than N1, and a set of M2 frames of the second fragment, where M2 is less than N2. The client device transmits a request for the M1 frames and the M2 frames and receives the M1 frames and the M2 frames. The client device presents the M1 frames and the M2 frames consecutively at the uniform, predetermined frame rate. The sequence of the M1 frames and the M2 frames has a presentation duration of (M1+M2)/F.
