Abstract: Methods and apparatus for enhanced delivery of content over a data network. In an aspect, a method is provided for transmitting services over a network. The method includes receiving one or more services having associated delivery requirements, determining that network bandwidth is available to meet the delivery requirements, and allocating the network bandwidth to the one or more services based on the delivery requirements to produce network bandwidth allocations. In an aspect, an apparatus is provided that includes receiving logic configured to receive one or more services having associated delivery requirements, and multiplexer logic configured to determine that network bandwidth is available to meet the delivery requirements, and to allocate the network bandwidth to the one or more services based on the delivery requirements to produce network bandwidth allocations.

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.

Abstract: 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.

Abstract: In general, this disclosure describes techniques for exchanging informati on 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 da ta with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. Th e multiplex module analyzes the quality and rate information to determine wh ether the segments of data that encoder modules desire to include in the cur rent superframe fit within the available bandwidth of a transmission channel . If the multiplex module determines the plurality of segments of data do no t fit within the available bandwidth, the multiplex module selects one or mo re of the segments to be resized based on the quality and rate information r eceived from the encoder modules.

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.

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. By using a primary message with abbreviated information to communicate whether changes to notification information have occurred without the need for further processing and/or addressed notification messages, system resources can be conserved. Corresponding apparatus are also disclosed.
