Abstract: In exemplary embodiments of the present invention systems and methods are provided to implement and facilitate cross-fading, interstitials and other effects/processing of two or more media elements in a personalized media delivery service so that each client or user has a consistent high quality experience. The effects or crossfade processing can occur on the broadcast, publisher or server-side, but can still be personalized to a specific user, thus still allowing a personalized experience for each individual user, in a manner where the processing burden is minimized on the downstream side or client device. This approach enables a consistent user experience, independent of client device capabilities, both static and dynamic. The cross-fade can be implemented after decoding the relevant chunks of each component clip, processing, recoding and rechunking, or, in a preferred embodiment, the cross-fade or other effect can be implemented on the relevant chunks to the effect in the compressed domain, thus obviating any loss of quality by re-encoding. A large scale personalized content delivery service can be implemented by limiting the processing to essentially the first and last chunks of any file, since there is no need to processing the full clip. In exemplary embodiments of the present invention this type of processing can easily be accommodated in cloud computing technology, where the first and last files may be conveniently extracted and processed within the cloud to meet the required load. Processing may also be done locally, for example, by the broadcaster, with sufficient processing power to manage peak load.

Abstract: Systems and methods for maintaining synchronization of repeater networks with Global Positioning System (GPS) signals using phase locked loops (PLLs) and based on generation of predicted control words for controlling local oscillator frequencies is described. The predicted control words can be generated based on performing a linear fit of control words generated over a predetermined duration of time. Phase locked loops with additional false GPS pulse identification and GPS signal loss compensation circuitry can enforce a false pulse count threshold and/or an error threshold. The additional circuitry and prediction of control words can overcome errors in GPS receiver outputs and maintain accuracy of signal timings across single frequency networks using inexpensive local oscillators.

Abstract: Systems and methods are presented for efficient cross-fading of compressed domain information streams on a user/client device. Exemplary systems may provide cross-fade between AAC/Enhanced AAC Plus information streams, between MP3 information streams, or between information streams of unmatched formats. These systems are distinguished in that cross-fade is directly applied to compressed bitstreams so a single decode operation is performed on the resulting bitstream. Thus, a set of frames from each input stream associated with the time interval in which a cross fade is decoded, and combined and recoded with a cross fade or other effect now in the compressed bitstream. Once sent through the client device's decoder, the user hears the transitional effect. The only input data that is decoded and processed is that associated with the portion of each stream used the crossfade, blend or other interstitial, and thus the vast majority of input streams are left compressed.

Abstract: Systems and methods for a non-data-aided (NDA) approach to advanced OFDM timing are provided. This approach allows for accurate OFDM symbol timing and synchronization by avoiding inter-symbol interference (ISI) in multipath environments where an earliest arriving signal may not be the strongest signal. The NDA approach may rely on generating and applying a bias correction to a combined correlation result of the multi-path signals.

Abstract: A vehicle messaging method (600) and system (100) can include any number of data sources (101-103), an interface (104) that formats messages and addresses from the data sources, and a corresponding number of messaging servers (111-113) that receive targeted messages intended for a predetermined subset of subscribers associated with a vehicle identification number (VIN). Each messaging server can include a corresponding controller (121-123) programmed to assign (604) targeted messages to a predetermined channel and encode (606) the addresses of the targeted messages to the predetermined subset of subscribers using a VIN or portion thereof. The controller can be further programmed to transfer (608) the targeted messages and addresses to a satellite uplink (107) and satellite (110) via a messaging uplink interface (106) for retransmission and reception by a plurality of selective call receivers 109 addressable individually using a predetermined VIN or portion thereof.

Abstract: An enhanced broadcast data service with reports locations of traffic enforcement camera locations (e.g., red light cameras and speed cameras) to users. Traffic enforcement camera information is aggregated, verified (e.g., particularly as to traffic enforcement camera type) and stored (e.g., at a server). A broadcast signal comprising program channels and at least one data channel having traffic enforcement camera information is transmitted to a plurality of receivers. Receivers store at least a subset of the traffic enforcement camera information available from the server and synchronize to it using periodic transmitted updates. Receivers compare receiver location data with stored camera location data, and display or generate audible alerts when the receiver is within a selected geographic range of a traffic enforcement camera. Alerts can be filtered as to camera type. A alerts can employ different color camera icons superimposed on a screen map depending on camera type or whether the camera is newly added.

Abstract: Systems, methods and apparatus for generating music recommendations based on combining song and user influencers with channel rule characterizations are presented. Such systems and methods output a playlist, which may be delivered as an information stream of audio on a user or client device, such as a telephone or smartphone, tablet, computer or MP3 player, or any consumer device with audio play capabilities. The playlist may comprise various individual audio clips of one genre or type, such as songs, or of multiple types, such as music, talk, sports and comedy. The individual audio clips may be ordered by a sequencer, which, using large amounts of data, generates both (i) user independent and (i) user dependent influencer weightings for each clip, and then combines all of such influencer weightings into a combined play weighting W for a given audio clip, for a given user. Taking the various play weightings W(Ui, Sj), a set of rules may be applied to generate a set of candidates C(Ui, Sj, Tk) to play to User j in each of Time slots k through k+m. Real time playlists may then be generated from the m sets of candidates by application of a set of rules, which may be channel rules, for example. The data used to generate influencer weightings may include user-specific data including preferences and detailed listening history, audio clip specific data, and data gleaned from various Internet accessible sources, including social media. In some embodiments a feedback loop may be implemented to gauge the accuracy of the dynamically generated playlists and modify the influencer weightings in response.

Abstract: Various applications, systems and methods for using, and enhancing V2V communications for various purposes are described. These systems and methods leverage various aspects of satellite radio broadcasts in combination with V2V communications. In some embodiments, V2V-enabled vehicles can receive advertisements or offers from RSEs, or even other V2V enabled vehicles, in a defined Target Region, which may then be played to a user in-vehicle once a given Trigger Region has been entered. By logging all advertisements or offers played to a user and sending the log to an RSE, for example, and from there to a content provider (e.g., an SDARS service operator), verified delivery of advertisements is achieved, which allows the content provider to obtain significant revenues from advertisers. In return for uploading the playback record from the vehicle to the RSE, a variety of incentives may be offered, such as (i) free or discounted satellite radio subscription; (ii) download credits for music or videos from an online store; (iii) reduced or free tolls on toll roads (e.g., RSE embedded in a toll collection plaza); (iv) premium audio or video content, (v) credit at an online store; and (vi) a special coupon code redeemable for merchandise.
