Abstract: In various embodiments, a media player or portable media device can enable a user to navigate and discover content or other media assets. The media player may analyze broadcasts and other content streams to determine currently playing and forthcoming content. The media player may switch from one source of content to another to find content that matches user preferences or criteria. The media player may generate playlists based on the matching content, and switch between sources of the matching content automatically. In some embodiments, the media player may receive user input to browse content using a navigation stream. Content associated with stations within the navigation stream may be output. As if the user were tuning a radio dial, the media player may determine what content to played back for each station. The media player may procure content and generate playlists to represent each station focus on by the user.

Abstract: For calculating a fingerprint of an audio signal, the audio signal is divided into subsequent blocks of samples. For the subsequent blocks, one fingerprint value each is calculated, wherein fingerprint samples of subsequent blocks are compared. Based on whether the fingerprint value of a block is higher than the fingerprint value of a subsequent block or not, a binary value is assigned, wherein information about a sequence of binary values is output as fingerprint for the audio signal.

Abstract: Audio data to be played back is associated with meta data indicating the timing of beat that serves as a basis for a rhythm of a music piece. In a fast-forward playback mode, the associated meta data is read. A portion of the audio data containing the timing of beat is determined as a playback portion A and the remaining portion in a beat-to-beat interval C is determined as a non-playback portion B. Only the playback portion A is sequentially played back and output. The relative duration of a playback portion A and a non-playback portion B is determined according to a playback speed required in fast-forward playback.

Abstract: A method for determining the task load in real-time. The method takes a difference in real-time between a first count value from a free running counter prior to a task executing, and a second count value after the task stops running. The task load may then be determined by using an accumulator to accumulate the difference between the first count value and the second count value over a reference interval and dividing the sum by a configurable reference interval. The individual task load computed in real-time may be used in scheduling an audio task.
