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:
A method for communicating notifications from a server to a device includ es sending a primary message including data indicating notification status i nformation (e.g. version number, update, system state change); and sending n otification messages or flows apart from the primary message addressed to sp ecific groups of devices (broadcast; composite address). Another method for obtaining notifications in a device from a server includes monitoring the pr imary message or flow including current notification status information, com paring the current notification information status information with a previo us notification status information to determine if a change in notification status information has occurred, and obtaining addressed notification inform ation- when a change in the notification status information has been determi ned. By using a primary message with abbreviated information to communicate whether changes to notification information have occurred, system resources can be conserved.
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.
Abstract:
Methods and systems for transmitting multiple service components in a single mediaFLO logical channel (MLC) stream within a MediaFLO® broadcast signal to distinguish data packets of different components based upon different media type header information or a component identifier added to the data packet header information. In a first embodiment, multiple service components of different media types are broadcast within the same MLC stream. Mobile device can separate received data packets within the MLC based upon their respective media type header information, and route each pack to its corresponding component processing module. In a second embodiment, different service components are identified with a component identifier that is added to the packet headers. A new layer in the protocol architecture stack can use the component ID within each data packet header to select and properly route the data packets for processing.
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:
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.

Abstract:
A venue-cast system and method for providing and receiving venue level transmissions and services, including discovery of a venue specific transmission by receiving an overhead signal from a non-venue network, extracting information for receiving the venue specific transmission from the overhead signal, and tuning to receive the venue specific transmission based on the extracted information. The venue level transmission may be provided and received in a manner that does not prevent an access terminal from receiving a local area or wide area transmission.
Abstract:
Methods and apparatus for conditional access of non real-time (NRT) content in a distribution system. A method includes encrypting NRT content with a control word (CW) to generate encrypted NRT content, providing the CW to entitlement control message (ECM) generators, receiving ECMs from the ECM generators, wherein each ECM comprises a unique encryption of the CW to provide conditional access to the CW, and providing the encrypted NRT content and the ECMs for transmission over a distribution network. An apparatus includes a synchronizer configured to provide a CW to ECM generators and receive ECMs from the ECM generators, wherein each ECM comprises a unique encryption of the CW to provide conditional access to the CW, and a management module configured to encrypt the NRT content with the CW to generate encrypted NRT content and provide the encrypted NRT content and the ECMs for transmission over the distribution network.
