The method further includes detecting an interruption event, at the primary communication device, during the active communication session. Additionally, the method includes determining that a first secondary communication device, in the set of secondary communication devices, has capability to process the interruption event, and transferring the interruption event to the first secondary communication device.

Abstract: A method and apparatus for distributing live video to multiple client devices is provided herein. In particular, a router is provided that acts on behalf of all client devices in its network. The router serves multiple groups of client devices with each group being formed by client devices having similar bandwidth requirements. The router then requests and receives video chunks from a network. The router then redistributes the video chunks to the multiple client devices using a multicast transmission. In particular, to minimize the demands on the core network, the router sets up a separate multicast to each group. Live video, of the appropriate quality is then multicast to each group.

Abstract: Devices and methods that match audio signatures to programming content stored in a remote database are disclosed. In one aspect of an embodiment, audio that includes primary audio from a device that outputs media content to one or more users is analyzed, in order to identify a presence or absence of corruption, and an audio signature is generated for an interval of time. In an aspect of a further embodiment, content being watched by a user is identified using a query audio signature and a message indicating the presence or absence of corruption.

Abstract: A method in a wireless communication terminal (103), including receiving a radio resource allocation comprising a plurality of sub-carriers that is a subset of available sub-carriers, wherein the available sub-carriers include a DC sub-carrier, wherein the DC sub-carrier and all but one edge-most sub-carrier of the plurality of sub-carriers are designated for transmission if the DC sub-carrier is between any two sub-carriers of the allocation, and all of the sub-carriers except the DC sub-carrier from the plurality of sub-carriers are designated for transmission if the DC sub-carrier is not between any two sub-carriers of the allocation.

Abstract: A video processing system detects an overlay image, such as a logo, in a picture of a video stream, the overlay for example being a broadcaster's logo. The detection is based on evaluation of blending characteristics of a picture frame. The method of detection of an overlay defines first and second areas within the image, the first and second areas being non-overlapping. Next an alpha-blended value is calculated for the mean color value of the second area with an overlay color value. Then, if the mean color value of the first area is closer to the alpha-blended value than it is to the mean color value of the second area, the overlay can be indicated as detected and defined within the picture. Detection of the overlay can be used to identify an owner of the video, or detect when a scene change such as a commercial occurs.

Abstract: A communication is provided that schedules both Distributed Virtual Resource Blocks (DVRB) and Localized Virtual Resource Blocks (LVRB) in a same frequency channel, thereby obtaining the benefits of frequency selective scheduling while minimizing the uplink feedback overhead. In one embodiment of the invention, the communication system assigns one or more downlink Physical Resource Blocks (PRBs) of multiple downlink Physical Resource Blocks (PRBs) to each user equipment (UE) given an LVRB to produce at least one reserved PRB and multiple non-reserved PRBs and assigns a part of each PRB of the multiple non-reserved PRBs to a UE given a DVRB. In another embodiment of the invention, the communication system assigns PRBs pre-reserved for localized transmission to UEs scheduled for LVRBs and assigns parts of multiple PRBs pre-reserved for distributed transmission to each UE given a DVRB.

Abstract: A method receives video content and metadata associated with video content. The method then extracts features of the video content based on the metadata. Portions of the visual, audio, and textual features are fused into composite features that include multiple features from the visual, audio, and textual features. A set of video segments of the video content is identified based on the composite features of the video content. Also, the segments may be identified based on a user query.

Abstract: Systems and methods for generating alerts and enhanced viewing experience features using on-screen data are disclosed. Textual data corresponding to on-screen text is determined from the visual content of video data. The textual data is associated with corresponding regions and frames of the video data in which the corresponding on-screen text was detected. Users can select regions in the frames of the visual content to monitor for a particular triggering item (e.g., a triggering word, name, or phrase). During play back of the video data, the textual data associated with the selected regions in the frames can be monitored for the triggering item. When the triggering item is detected in the textual data, an alert can be generated. Alternatively, the textual data for the selected region can be extracted to compile supplemental information that can be rendered over the playback of the video data or over other video data.

Abstract: A method implemented in a computer system for controlling the delivery of data and audio/video content. The method delivers primary content to the subscriber device for viewing by a subscriber. The method also delivers secondary content to the companion device for viewing by the subscriber in parallel with the subscriber viewing the primary content, where the secondary content relates to the primary content. The method extracts attention estimation features from the primary content, and monitors the companion device to determine an interaction measurement for the subscriber viewing the secondary content on the companion device. The method calculates an attention measurement for the subscriber viewing the primary content based on the attention estimation features, and the interaction measurement, and controls the delivery of the secondary content to the companion device based on the attention measurement.
