摘要： Systems and methods are presented for cross-fading (or other multiple clip processing) of information streams on a user or client device, such as a telephone, tablet, computer or MP3 player, or any consumer device with audio playback. Multiple clip processing can be accomplished at a client end according to directions sent from a service provider that specify a combination of (i) the clips involved; (ii) the device on which the cross-fade or other processing is to occur and its parameters; and (iii) the service provider system. For example, a consumer device with only one decoder, can utilize that decoder (typically hardware) to decompress one or more elements that are involved in a cross-fade at faster than real time, thus pre-fetching the next element(s) to be played in the cross-fade at the end of the currently being played element. The next elements(s) can, for example, be stored in an input buffer, then decoded and stored in a decoded sample buffer, all prior to the required presentation time of the multiple element effect. At the requisite time, a client device component can access the respective samples of the decoded audio clips as it performs the cross-fade, mix or other effect. Such exemplary embodiments use a single decoder and thus do not require synchronized simultaneous decodes.

摘要： In a customized content delivery service, such as, for example, a personalized music streaming service delivered over various wireless networks, an end-user can be given the ability to refine or select programming which is presented to them. One approach to achieving this is to present the user with a range of user preference controls, such as sliders, which can be mapped to attributes contained within the scheduling system. Thus, systems and methods are presented for the representation and delivery of such attributes to effect a personalized server, to map controls to these attributes, and to simplify the controls presented to an end-user. In exemplary embodiments of the present invention a recommender uses channel specifications and a user profile, as dynamically modified and updated by user preferences expressed via said user preference controls, to generate user and channel specific playlists, to give a user the personalized audio experience he or she actually desires.
摘要翻译：在定制的内容递送服务中，例如，通过各种无线网络递送的个性化音乐流媒体服务，终端用户可被赋予提炼或选择向其呈现的节目的能力。实现这一点的一种方法是向用户呈现一系列用户偏好控件，例如可以映射到调度系统中包含的属性的滑块。因此，呈现系统和方法用于表示和传送这些属性以实现个性化服务器，将控件映射到这些属性，并简化向最终用户呈现的控件。在本发明的示例性实施例中，推荐者使用通过用户偏好表达的用户偏好控制来动态修改和更新的频道规范和用户简档，以产生用户和频道特定的播放列表，以向用户提供他或他她实际上是欲望。

摘要： 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.
摘要翻译：提出了基于将歌曲和用户影响者与频道规则特征相结合来产生音乐推荐的系统，方法和装置。这样的系统和方法输出播放列表，其可以作为诸如电话或智能电话，平板电脑，计算机或MP3播放器的用户或客户端设备或具有音频播放功能的任何消费者设备的音频信息流来传送。播放列表可以包括一种类型或类型的各种各样的音频剪辑，诸如歌曲，或者多种类型，例如音乐，谈话，运动和喜剧。各个音频片段可以由定序器排序，序列发生器使用大量的数据同时生成用户独立的和（i）每个剪辑的用户依赖的影响者权重，然后将所有这些影响者权重组合成组合播放给定用户对给定音频剪辑加权W。采用各种播放权重W（Ui，Sj），可以应用一组规则来生成在每个时隙k至k + m中向用户j播放的一组候选C（Ui，Sj，Tk）。然后可以通过应用一组规则（例如，可以是信道规则）从m个候选集合生成实时播放列表。用于产生影响者权重的数据可以包括用户特定的数据，包括偏好和详细的监听历史，音频剪辑特定数据以及从各种因特网可访问源（包括社交媒体）收集的数据。在一些实施例中，可以实现反馈回路以评估动态生成的播放列表的准确性并且响应地修改影响者权重。
