  • Patent number: 9723345
    Abstract: A network device includes an electronic program guide (EPG) component configured to receive EPG data associated with an EPG from an external EPG server. The network device further includes a manager component comprising a pre-loader configured to pre-render and send first EPG images, associated with the EPG, that are frequently re-used to multiple client devices; a graphics interceptor configured to generate one or more second EPG images based on a graphics call, wherein the graphics call causes a first one of multiple client devices to display the one or more second EPG images; and a window manager configured to track changes in the one or more second EPG images and send a modified EPG image that includes the changes, or a modified portion of an EPG image that includes the changes, to the first one of the multiple client devices.

  • Patent number: 9456398
    Abstract: A mobile device includes a mobile network module to present media content using a public network and a home network module to present media content from a home network. The mobile device uses the mobile network module to receive a media streaming session via a broadband cellular connection and detects a local wireless connection to a device in a home network. The mobile device uses the home network module to initiate, via the local wireless connection, a home media session with the device in the home network and matches content of the home media session with content of the media streaming session. The mobile device presents, to a user and using the home network module, the matched content of the home media session and disables the media streaming session.

  • Patent number: 9264750
    Abstract: One or more servers in an IP network receive, from a user device, a selection of live streaming content and assemble an index file including links to chunks of the selected live streaming content and links to advertising files for insertion within the selected live streaming content. The one or more severs send, to the user device, a link to the index file associated with the selected live streaming content and receive, from the user device, a streaming request for the selected live streaming content. The one or more servers send, to the user device, the index file including the links to chunks of the selected live streaming content and the links to advertising files for insertion within the selected live streaming content. The user device may use the links to combine the chunks of the selected live streaming content and the advertising files into a single linear presentation. A standards-based client for the user device is used with the server side implementation.

  • Patent number: 8938770
    Abstract: A server receives a request for delivery of media from a client, and determines if the client has a capability to tune to a quadrature amplitude modulated (QAM) channel carried by a first network. The server sends a message to the client to instruct the client to tune to the QAM channel to receive the media via the first network if it is determined that the client has the capability to tune to the QAM channel. The server sends the media to the client if it is determined that the client does not have the capability to tune to the QAM channel.

  • Patent number: 8925009
    Abstract: A network device sends a first set of images associated with an electronic program guide (EPG) to a client device. The network device determines that an image of the first set of images has been modified, and receives one or more calls for displaying the first set of images at the client device. The network device sends the modified image, or one or portions of the image that have been modified, to the client device without sending a remainder of the images in the first set of images, or without sending the remaining portions of the image.

  • Patent number: 8732761
    Abstract: A system may include a client and a home media server in communication with the client. The home media server may be configured to receive a request for media content from the client; determine content restrictions associated with the client; discover at least one other home media server; receive content listings of media content from the at least one other home media server; aggregate the received content listings to create a unified content listing including instances of media content stored on multiple home media servers; filter the unified content listing according to the content restrictions; and send the filtered unified content listing to the client.

  • Patent number: 8468234
    Abstract: Disclosed are methods and systems that include presenting signals corresponding to a time-series of traffic on links of a network to a band-pass filter to obtain band-limited signals, the band pass filter centered substantially about a frequency corresponding to traffic to be tracked, determining coherence values of the band-limited signals, and, based on a comparison of the coherence values to a threshold, forming at least one map of the routing of the traffic based on the corresponding links.

  • Publication number: 20120316965
    Abstract: A network device in a customer premises network collects profile data for a client device of multiple client devices in the customer premises network and sends the client profile data to a remote provider network. The network device receives, from the remote provider network, a group of advertisement files for targeted advertising to the client device and stores, in a memory, the group of advertisement files. The network device detects an advertisement insertion cue in linear program content being streamed to the client device, selects an advertisement file from the stored group of advertisement files, and inserts the selected advertisement file into the linear program content being streamed to the client device.

  • Patent number: 7917953
    Abstract: Methods and systems can reduce the spread of computer files or data on a network by obtaining and tracking times of arrival for chunks of data transmitted on the network. The times of arrival for a node can be transformed into time-series and periodograms computed from the time-series. Successive periodograms can be compared to determine changes in the strongest peaks of the periodograms. If a new peak is identified, a search for the occurrence of the peak in previous periodograms can be conducted. If no peak having a matching frequency is found, a search for the peak in the periodograms for neighboring nodes can be performed. If matching peaks are found, the associated data stream can be classified. Predictions of the timing and length of associated data packets can be used to randomly interrupt transmission of associated data packets resulting in reducing the spread of the classified data stream.

  • Patent number: 7574597
    Abstract: A system acquires information about communication among wired or wireless nodes [110, 210] in a network [100, 200] by intercepting chunks of data in the network by a wired or wireless tap [120, 220] located among the wired or wireless nodes [110, 210] in the network. Characteristic information [400] about the intercepted chunks of data may be obtained. The characteristic information may include times of arrival [410] of the chunks of data at the wired or wireless tap [120, 220] and identifiers of wired or wireless source nodes [420] that sent the chunks of data. At least one signal may be constructed to represent the characteristic information over time.
