摘要:
A fiber optic telecommunication system has master site linked to a plurality of subscriber interface sites by a single pair of optical fibers. Downlink messages are transmitted in a continuous TDM format over a first optical fiber from the master site to subscriber interface sites, and in a burst mode TDMA format over a second optical fiber from the subscriber interface sites to the master site. Each subscriber interface site is coupled to the optical fiber link by way of a multiple fan-out fiber coupling pedestal at a common location on the fiber pair. To prevent collisions between successive uplink bursts from the subscriber interface sites, a guard band separates successive uplink messages from one another. The guard band duration accommodates optical fiber transmission distance between the common location on the uplink optical fiber and the subscriber interface site whose differential optical fiber transmission distance from the common location is greatest. A subscriber location has a television decoder associated with the subscriber's television set, through which television channel selection signals are input by the subscriber for transmission from the subscriber interface site to the master site. Power is provided by way of a replaceable battery pack, housed in a subterrestrial bell jar configuration, effectively insulating the battery pack from extreme temperature changes and the intrusion of moisture.

Methods and systems are disclosed for providing customized content to users based on their location. In one embodiment, for each of one or more content providers, a customized content delivery function receives information from the content provider defining a number of geographic shapes selecting corresponding geographic areas. Preferably, each of the geographic shapes overlaps at least one other of the geographic shapes and is assigned an importance level. For each geographic shape, the content provider defines one or more tags for the geographic shape and assigns a weight to each of the one or more tags. Thereafter, when a request is received from a requestor, one or more content items are selected for delivery to the requestor based on the geographic shapes, the tags and corresponding weights for the geographic shapes, and the location of the requestor.
摘要:
A method and system for arranging advertising breaks based on channel surfing characteristics of viewers. The surfing characteristics of a plurality of viewers is determined, the surfing characteristics bearing on a likelihood of a respective viewer channel surfing. Advertisements are assigned to time slots among a plurality of channels based on the surfing characteristics of the plurality of viewers to form an advertising schedule. Programming is delivered with the plurality of advertisements according to the advertising schedule. The reduction of simultaneous channel surfing increases availability and efficient use of a shared medium by a plurality of different users.

This disclosure relates to enabling a potential participant to define preferences for a talk radio program. In one embodiment, via a radio client, a potential participant defines preferences for a talk radio program wherein the preferences include at least a topic of interest and a semantic relevance. In one embodiment, the participant preferences also include a time availability indicating when the potential participant is available to participate in the talk radio program. The radio client sends the preferences to a talk radio program service. When a talk radio program satisfying the preferences of the potential participant is scheduled or otherwise available, the talk radio program service notifies the potential participant. A topic of the talk radio program is semantically related to the topic of interest of the potential participant to at least a degree defined by the semantic relevance.
摘要:
Targeted or other advertising may comprise one or more advertisements presented in a virtual world environment constructed according to consumer parameters, with the advertisements presented according to rules, scripts, or other parameters defined by the advertiser(s). For instance, one or more consumer computing device(s) can access data defining a brand name, logo, and/or message and can access data defining consumer preferences for the context in which advertisements are to be presented. For example, the context may vary according to viewer identity, programming content, time of day, and the like. Then, the consumer computing device(s) can render a virtual world based on the consumer preferences with the virtual world also comprising the advertisement(s) generated based on advertiser definitions.

A system and method are disclosed for providing a radio station for playback at a user device using previously obtained Digital Rights Management (DRM) locked content for the radio station. In one embodiment, a radio station application and DRM locked content to be used by the radio station application are downloaded to a user device, which is preferably a mobile user device. The DRM locked content includes a number of DRM locked songs that may be used for the radio station. Thereafter, the radio station application obtains a playlist for the radio station, where the playlist for the radio station includes at least a subset of the DRM locked content provided to the user device for the radio station. Playback of the playlist for the radio station is then provided at the user device, and playback is reported to a remote service for royalty tracking.

Exemplary embodiments provide for optimizing operation of a radio program, wherein the radio program is operated by a host using a host process. Aspects include collecting and storing contextual information from participants of the radio program, the participants including listeners and callers of the radio program; analyzing the contextual information; and enabling at least one feature on the host process based at least in part on the contextual information.
摘要:
A skip function for broadcast or multicast media content is disclosed. In general, a receiving device simultaneously receives two or more content streams transmitted for one or more radio stations and provides a skip function by buffering and switching between the two or more content streams. Initially, the receiving device provides playback of a first content stream of the two or more content streams. During playback of the first content stream, the receiving device buffers one or more most recently received content items from the other content streams. When a skip request is received, the receiving device performs a skip function by switching playback from the first content stream to a second content stream of the two or more content streams beginning at the start of the one or more most recently received content items from the second content stream that have been buffered at the receiving device.
