Abstract

A television signal recording apparatus comprises a recording unit that makes recordings of television signals and stores metadata representing information in respect of the recordings including the channel and the recording time. A graphical display of made recordings and scheduled recordings is produced in which graphical objects representing respective recordings are arranged in two dimensions, ordered in a first dimension on the basis of the channels and ordered in a second dimension on the basis of the recording times. In the second dimension, the graphical objects are arranged along a time axis which includes discontinuities at times when no recording is present, the discontinuities being graphically represented by graphical symbols that are different according to the period of the discontinuity. An electronic program guide is produced with a similar format, the programs being filtered to select programs and discontinuities being present at times where there is no selected program.
