摘要:
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.

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.

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.

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.

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.

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.

Methods and devices enable users of still or video image content to indicate objects within images in order to obtain more information regarding products of interest. Selected portions of an image or coordinates within the image may be included in a product query message transmitted to a server. The server receiving image information may process the information to recognize objects or particular products within the image selection. Recognized objects or products may be compared to a database of available merchandise to determine availability. Information regarding commercially available products may be included in a product information message transmitted to the user's computing device. Users may initiate a purchase transaction for recommended products based on the product information. The image may be broadcast by a variety of content delivery services including a mobile broadcast TV network.
