Problems solved by technology

[0010] A further problem that results is that observation of how content is used is rather unreliable, since the devices playing the content generally do not register who actually listens to and / or views the content; and asking directly to rate what is being played also gives Additional time-consuming burden on the user (because of rating responses)
[0011] The problem with the current recommender (from the previous example) is that it cannot effectively analyze the playlist edited by the user

Embodiment Construction

[0030] figure 1 A method of generating a user profile on a media device with a playlist is shown. The media device may be a jukebox, set-top box, television, personal computer, DVD player, radio, video recorder, and / or similar device that can play playlists and / or recommended content from a user profile.

[0031] A playlist is a sorted list of, for example, music tracks (songs). It may also contain other content, such as picture clips (video).

[0032] A song is a piece of audio with metadata attached to or embedded in it (such as an MP3 file whose header contains song information).

[0033] Accordingly, a video contains image segments (eg MPEG frames) with corresponding metadata attached or embedded therein (eg a header containing various information about the video MPEG file).

[0034] Music metadata describes the characteristics of a song. Typical song characteristics are:

[0035] Nominal features such as track title and author.

[0036] Categorical or numerical fea...

Abstract

In a method and device for generating a user profile on the basis of playlists, the user profile is generated on the basis of the user's own playlists and properties derived from them. In this way, more playlists are considered in the generation of a user profile, thereby generating a more reliable user profile. Aspects taken into account includes frequency of occurrence, creation date of the playlist, and relation between content items (songs, video, etc.) in one or more playlists.

Description

technical field [0001] The present invention relates to a method of generating a user profile on a media device that has acquired a set of playlists. [0002] Furthermore, another aspect of the invention relates to the generation of recommended playlists. [0003] The invention also relates to a computer system and a computer program product for implementing the method. [0004] Additionally, the invention relates to a media device on which the method can be performed. Background technique [0005] US Patent 2002 / 0040326 discloses a method provided for selecting categorized content items for download to a mobile device. The method monitors content items presented, played and visually displayed on said mobile device. A content item is an item of any media type (eg MP3) that can be downloaded as a data stream onto the mobile device. [0006] It is known in the prior art to utilize user preferences (for example in the form of matching user profiles) to recommend content to ...
