Abstract

A system and a method for program recommendation are described. In order to present a user a recommendation for a choice of audio or video content pieces broadcast consecutively at a plurality of different channels, (a) piece scores of content pieces are calculated, indicating a match of a corresponding content description with a profile, (b) and sequence scores are calculated for a plurality of sequences of content pieces, said sequence scores being based at least on said piece scores and on a correlation of content descriptions of at least two pieces contained in the sequence. A recommended sequence is chosen according to the sequence score. Preferably, one or, more preferred sequences are shown to the user in a lattice representation.
