摘要： 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.

摘要： 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.

摘要： 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.
