Abstract: A method and apparatus are provided for generating a personalized radio channel playlist by simultaneously buffering multiple received channels from one or more source streams, and then selecting songs or tracks to playback from the buffered channels. Users can specify favorite channels for building their personal playlists, or multiple default playlist channels can be provided by genre or channels related in some other way. Navigation tools permit users to skip ahead and backward in the playback stream. A personalized radio channel playlist can be implemented as (1) content selected from buffered channels based on user preferences for artists, songs and the like, or (2) as a Mix Channel in which content from selected buffered channels is automatically mixed for playback in response to selection of a preset button assigned to the Mix Channel.

Abstract: A cuepoint determination system utilizes a convolutional neural network (CNN) to determine cuepoint placements within media content items to facilitate smooth transitions between them. For example, audio content from a media content item is normalized to a plurality of beats, the beats are partitioned into temporal sections, and acoustic feature groups are extracted from each beat in one or more of the temporal sections. The acoustic feature groups include at least downbeat confidence, position in bar, peak loudness, timbre and pitch. The extracted acoustic feature groups for each beat are provided as input to the CNN on a per temporal section basis to predict whether a beat immediately following the temporal section within the media content item is a candidate for cuepoint placement. A cuepoint placement is then determined from among the candidate cuepoint placements predicted by the CNN.
