  • Patent number: 11647241
    Abstract: A Reductive Edging device and computer program product. The Reductive Edging device has a processor, memory coupled to the processor and non-transitory instructions embedded in the memory that when executed by the processor causes the device to perform a method for reductive edging. The method includes, prior to sending a media segment to a client device, performing error de-emphasis operations and sending information associated with error de-emphasis.

  • Patent number: 11611798
    Abstract: To reduce latency in streaming media a playlist requested from a content delivery network may be modified to have modified segmentation. After receiving the playlist from the content delivery network, the location of one or more I-frames in each segment in the playlist may be determined and these locations may be used to generate the modified playlist. The modified playlist may then be sent to a client device. Media segments may be modified in accordance with the modified segmentation of the modified playlist to generate modified media segments that can be sent to the client device.

  • Patent number: 11563987
    Abstract: Prior to receiving a request from a client device for information from a content distribution network (CDN), a Reductive Edging device predictively requests the information from the CDN based on prior user activity and stores it in memory. The Reductive Edging device is thus configured to respond to the request from the client device for information from the CDN with the information stored in the memory prior to receiving the request.

  • Publication number: 20220337615
    Abstract: In dynamic sessional redirection a server receives a request originating from a client device from a proxy server and analyzed for context information. Proxy rerouting rules are determined from the context information and sent to the proxy server. The server then sends a response to the first request to the proxy server addressed to the client device. A proxy may include a processor coupled to a memory having a dynamically reconfigurable rules table embodied therein having rerouting rules for data traffic between a client and a server. An application programming interface (API) is configured to dynamically change one or more rerouting rules in the reconfigurable rules table. The proxy is configured to reroute data traffic between client and server according to the rerouting rules.

  • Patent number: 11394734
    Abstract: A method for redirecting data traffic includes receiving a first request from a client device addressed to a first server and sending the first request from the client device to the first server, and determining rerouting rules. A response may be received addressed to client device from the first server the response is sent to the client device. Metadata from client device may be received wherein the metadata provides information about a second request from the client device and a second request from the client device is received addressed to the first server, the information about the second request in the metadata is compared to the rerouting rules and the second request is sent according the rerouting rules.

  • Patent number: 11032347
    Abstract: A method system and computer program product for bandwidth usage reduction in media streaming, comprises, receiving user streaming information from a client device and refining a user model with the user streaming information. The user streaming information reflects a user's media consumption habits. Subsequently a request for a media playlist from the client device is received and media segments are prospectively requested based on the user model before receiving a request for the media segments. The requested media playlist is sent to the client device; and the prospectively requested media segments are sent upon receiving a request for a media segment from the client device.

  • Publication number: 20200322698
    Abstract: A method, system and computer program product for enabling interactive video on non-browser based devices comprising receiving a media segment and analyzing the media segment for a link marker location having a corresponding network address. The link marker location is stored and sent to the client device. The client device sends the interface information, which is received and compared to the link marker location. A request is sent to a network address corresponding to link marker location when the interface information indicates an activation has occurred at the link marker location within the media segment during a presentation on the client device. The device at the network address sends resources, which are received over the network and converted into a resource media segment. The resource media segment is then sent to the client device.

  • Patent number: 10755673
    Abstract: The disclosure features information display systems that include a display device, at least one sensor, and an electronic processor connected to the display device and to the at least one sensor. During operation of the system, for a set of pixels of the display device that are used to display visual information, the electronic processor is configured to determine a range of target luminance values for a subset of the pixels for which a Weber contrast value is less than the contrast threshold value, adjust luminance values for the set of pixels so that at least some members of the subset of pixels have Weber contrast values, based on their adjusted luminance values, that exceed the contrast threshold value, and display the visual information on the display device using the members of the set of pixels with the adjusted pixel luminance values.

  • Publication number: 20180367861
    Abstract: The present disclosure describes methods and systems directed towards temporal generation of content playlists. The generated playlists (i.e. binge watching playlist) facilitates a user to view a variety of different types of live content (i.e. live television) in an automated fashion that resembles binge watching as implemented via DVD or streaming content. This allows content to be provided in succession during the span of time (i.e. binge watching session) without the user needing to search for or request the next content to be displayed on the user device.

  • Publication number: 20180316953
    Abstract: An integrated media platform employs techniques for streaming local and subscriber content. These techniques include determining at least one local channel is available over an over-the-air (OTA) communication network, receiving subscriber content for at least one subscriber channel over a first communication network, providing metadata content for display by a client device, where the metadata content includes information for the at least one subscriber channel and the at least one local channel, receiving a request for local content associated with the at least one local channel, tuning a network interface (e.g., an antenna) to receive the local content over the OTA network, transcoding the local content into streaming content, and providing the local content to one or more client devices connected to a local access network (LAN).
