  • Patent number: 10027432
    Abstract: Techniques for sending and receiving broadcast information are described. In an aspect, broadcast metadata may be generated for broadcast information and may include location and time criteria used by terminals to filter the broadcast information. Each location and time criterion may include (i) a location criterion given by a target location and a presence or absence requirement and (ii) a time criterion given by a time period in which the location criterion applies. A terminal may receive the broadcast metadata prior to or with the broadcast information, obtain location and time criteria from the broadcast metadata, and filter the broadcast information based on the location and time criteria. The terminal may evaluate each location and time criterion by determining its location within a specified time period and determining whether its location is within or outside a specified target location, as indicated by the presence or absence requirement.

  • Patent number: 9741853
    Abstract: Disclosed are methods for stress memorization techniques and transistor devices prepared by such methods. In one illustrative embodiment, the present disclosure is directed to a method involving fabricating an NMOS transistor device having a substrate and a gate structure disposed over the substrate, the substrate having a channel region underlying, at least partially, the gate structure, the fabricating involving: performing a nitrogen ion implantation process by implanting nitrogen ions into the substrate to thereby form a stress region in the substrate, the stress region separated by the channel region, wherein the stress region has a stress region depth; forming a capping material layer above the NMOS transistor device; and, with the capping material layer in position, performing a stress forming anneal process to thereby form stacking faults in the stress region. In another embodiment, an amorphization ion implantation is performed prior to, after or along with the nitrogen ion implantation.

  • Patent number: 9485535
    Abstract: Systems, apparatus and methods provide an automatic capability for generating interactivity event applications for execution on receiver devices within a broadcast network based upon interactivity event application data, information and sequence logic. Interactivity event content providers may provide to a broadcast network interactivity event application data, event metadata information and sequence logic a broadcast network. Interactivity resources for interactivity sequences associated with one or more real-time channels are broadcast over the broadcast network such that the resources share a file data flow, or such that they can be carried on separate file data flows. File data flow identifiers and overhead flow identifiers are indicated in the Service SI. Interactivity signaling messages for interactivity sequences associated with one or more real times channels are broadcast on auxiliary flows.

  • Publication number: 20160226608
    Abstract: Methods and systems simplify discovery and handoff for multi-frequency broadcast receiver devices, such as mobile TV devices, by providing a virtual home channel that is not dependent on a single frequency network upper layer. The methods and systems may be used in conjunction with a single frequency network upper layer to support areas without upper layer available, or to off load some portion of the common data bandwidth in the single frequency network. For example, the single frequency network may only carry frequency data for the multiple frequency network or only the frequency data for networks with comprehensive market metadata.

  • Patent number: 9369989
    Abstract: Methods and apparatus for communication of notifications are disclosed. A disclosed method for communicating notifications from a server to a device includes sending a primary message including data indicating notification status information; and sending notification messages apart from the primary message addressed to specific groups of devices. Similarly, another disclosed method for obtaining notifications in a device from a server includes monitoring the primary message including current notification status information, comparing the current notification information status information with a previous notification status information to determine if a change in notification status information has occurred, and obtaining addressed notification information when a change in the notification status information has been determined.

  • Patent number: 9155023
    Abstract: Apparatus and methods for communication system state information change to wireless devices in a content server network in a resource and power efficient manner are disclosed. In particular, a disclosed method for conveying system state information to a wireless device includes sending a primary message including first information configured to communicate a current system state to the wireless device, and then sending second information set usable by the wireless device to update system state information. By summarizing or abbreviating the first information, a receiving device can easily compare to past system states to determine whether further processing, such as processing of the second information, is needed, thereby affording the conservation of processing and power resources of a receiving device. Corresponding apparatus are also disclosed.

  • Patent number: 9113488
    Abstract: A multi-radio device, such as User Equipment (UE), may experience coexistence issues among various ones of its constituent radio devices that operate at the same time. Various aspects of the disclosure provide techniques to mitigate coexistence issues in multi-radio devices, where significant in-device coexistence problems can exist. In particular, a method for coexistence of multi-radio devices is described. The method includes identifying, at an upper layer of a multi-radio UE, a type of incoming broadcast stream data. The method further includes determining a coexistence policy for operation of communication resources within the multi-radio UE based on the type of the incoming broadcast stream data. The method also includes arbitrating, at a lower layer of the multi-radio UE, between the communication resources based on the coexistence policy.

  • Publication number: 20150156498
    Abstract: In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.

  • Patent number: 8886745
    Abstract: Embodiments relate to systems and methods for delivering auxiliary data to a wireless or other device. Content, such as audio, video or textual content, can be hosted by a server for delivery to the device. The content can have associated resources, for example icons, barkers, intros, and outros that are associated with television programming or other media content. A metadata document can describe the set of resources or other auxiliary data associated with a service, channel or content by indicating a resource descriptor, and a URL or other associated resource locator information. The metadata document can be encoded in XML or other formats. The device can locate resources that are intended to be delivered with selected content, since links to the resources are integrated in the metadata document. From the resource descriptor, the device can also identify how a particular resource should be utilized for the service, channel or content.
