  • Radio play While radio play is still very popular, more and more people are listening to music streamed over the Internet and/or downloaded and pre-cached to various communication devices to be listened to at a later time.

In addition, the radio rankings are generally based solely on which songs are played by a DJ and do not take into account the number of listeners actually listening to the songs. In addition, radio does not offer any way to sense whether a user listens to a song, turns the radio off when a song is played or changes the channel when a song is played.

  • a predictor can use the above variables along with variables indicating ramp-up velocity (score change rate over time, start rate over time, heart rate over time etc.). In this way, the most impactful metrics will have the highest weight in the model.
  • Some embodiments of the systems and methods described herein may include computer software and/or computer hardware/software combinations configured to implement one or more processes or functions associated with the methods such as those described above and/or in the related applications. These embodiments may be in the form of modules implementing functionality in software and/or hardware software combinations. Embodiments may also take the form of a computer storage product with a computer-readable medium having computer code thereon for performing various computer-implemented operations, such as operations related to functionality as describe herein.
  • the media and computer code may be those specially designed and constructed for the purposes of the claimed systems and methods, or they may be of the kind well known and available to those having skill in the computer software arts, or they may be a combination of both.
  • Examples of computer-readable media within the spirit and scope of this disclosure include, but are not limited to: magnetic media such as hard disks; optical media such as CD-ROMs, DVDs and holographic devices; magneto-optical media; and hardware devices that are specially configured to store and execute program code, such as programmable microcontrollers, application-specific integrated circuits ("ASICs"), programmable logic devices ("PLDs”) and ROM and RAM devices.
  • Examples of computer code may include machine code, such as produced by a compiler, and files containing higher-level code that are executed by a computer using an interpreter.
  • Computer code may be comprised of one or more modules executing a particular process or processes to provide useful results, and the modules may communicate with one another via means known in the art.
  • some embodiments of systems described herein may be implemented using assembly language, Java, C, C#, C++, or other programming languages and software development tools as are known in the art.

Abstract

L'invention concerne des systèmes et des procédés pour délivrer des flux de contenu personnalisés sur une variété de dispositifs et de réseaux. Des préférences d'utilisateur, des personnalisations et un contenu sont mis à disposition de l'utilisateur via des clients spécialisés pour des environnements domestique, véhiculaire, professionnel et portable. Afin de permettre des flux de contenu personnalisés sur des dispositifs qui sont connectés par intermittence ou qui utilisent la bande passante du réseau durant les heures creuses, le système prescrit un moteur de séquençage de contenu distribué ainsi qu'un profil utilisateur synchronisé distribué et des définitions de station/canal. Le système est également conçu pour prendre en charge des joueurs qui sont connectés via des connexions unidirectionnelles ou asymétriques, des radios par satellite avec ou sans liaison de données dans le sens montant par exemple.
