| 20080256032 | Hierarchical Playlist Generator - A playlist generator partitions the playlist generation process into a multi-stage, hierarchical process. At an example highest hierarchical level, the user's “general” preferences are applied. These general preferences reflect the user's “tastes”, and are relatively constant. At a lower level of the hierarchy, the user's “specific” preferences are applied. These specific preferences reflect the dynamic time-dependent or event dependent aspects of a user's entertainment preferences. The high-level preferences generate a subset of material from the global collection of material, and the lower-level preferences are applied to this subset of material as the user's immediate preferences change. By segregating the playlist generation process hierarchically, efficiency is gained by applying immediate preference changes to a smaller subset of material, and coherency is improved by limiting the subsequent selection processes to a given subset of the material. | 10-16-2008 |
| 20080263476 | Playlist Based on Artist and Song Similarity - A playlist generator allows a user to identify a particular artist as the seed for a one-click playlist generation. When the user identifies the artist, a list of similar artists is presented for the user's approval or modification. When the user is satisfied with the list of artists, the user initiates the playlist generation. The system iteratively selects an artist from the list, and selects a song by that artist, based on the similarity of songs by the artist. The user may control the degree of variety among artists and among songs. | 10-23-2008 |
| 20080313222 | Apparatus and Method For Visually Generating a Playlist - An apparatus and method for dynamically generating a playlist to a user are provided. An on-screen user interface display is used for generating a display of a sequence of media desired by a user, in which an artist map having a large collection of music is displayed so that a user can selectively create a playlist path to generate the playlist according to a configuration of attribute values that corresponds to a specified position selected by a user on the artist map within the display. The artist map may include an overview of a large music collection based on the sound of music in such a way that similar artists are placed close together and provides at least one of the following: artist, album, style, mood, genre, tempo, and year of music. | 12-18-2008 |
| 20090006353 | Method and Apparatus for Selecting Items from a Number of Items - Techniques are presented for selecting one or more items from a collection of items. To select the one or more items, an interface is provided that is adapted to allow a user to define one or more weights. Each weight corresponds to one of a number of similarity criteria. Each item also corresponds to the number of similarity criteria. The one or more weights define a similarity function. The similarity function is applied to the one or more similarity criteria corresponding to the one or more weights and to each of the items in order to select one or more items from the collection of items. The interface can comprise movable markers corresponding to similarity criteria. Locations of the movable markers can be used to weight similarity criteria when creating the similarity function. | 01-01-2009 |
