    • Methods and apparatus for service acquisition in a broadcast system. In an aspect, a method includes detecting whether a loss of service has occurred, and initiating acquisition attempts during an aggressive acquisition phase if a loss of service has occurred, wherein a backoff time interval between successive acquisition attempts is constant or increased, and wherein the aggressive acquisition phase ends when service acquisition is achieved or a selected number of acquisition attempts have been performed. An apparatus includes interface logic configured to detect whether a loss of service has occurred, and processing logic configured to initiate acquisition attempts during an aggressive acquisition phase if a loss of service has occurred, wherein a backoff time interval between successive acquisition attempts is constant or increased, and wherein the aggressive acquisition phase ends when service acquisition is achieved or a selected number of acquisition attempts have been performed.

    • 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.
    • 实施例涉及将辅助数据传送到无线或其他设备的系统和方法。 诸如音频,视频或文本内容的内容可以由服务器托管以传送到设备。 内容可以具有与电视节目或其他媒体内容相关联的相关联的资源,例如图标,标记,简介和外联。 元数据文档可以通过指示资源描述符以及URL或其他相关联的资源定位符信息来描述与服务,信道或内容相关联的资源集合或其他辅助数据。 元数据文档可以以XML或其他格式进行编码。 设备可以定位要与所选内容一起传递的资源,因为到资源的链接被集成在元数据文档中。 从资源描述符,设备还可以识别如何将特定资源用于服务,频道或内容。

    • Methods and apparatus for distributing and acquiring overhead flow data in a multi-frequency network. In an aspect, a method includes generating initial acquisition flows (IAFs) that describe how content multiplexes are distributed in the multi-frequency network and provide flow identifiers for overhead flows associated with the content multiplexes, and transmitting the IAFs on pre-assigned flow identifiers. Another method includes receiving IAFs that describe how content multiplexes are distributed in the multi-frequency network and specify flow identifiers for overhead flows associated with the content multiplexes, wherein the IAFs are received using pre-assigned flow identifiers, processing the IAFs to determine VM sets associated with current wide and local areas of the multi-frequency network, determining overhead flow related information associated with selected content multiplexes in the VM sets, and acquiring overhead flow data associated with the selected content multiplexes using the associated flow identifiers.
