Television signal receiver (television apparatus, video recorder, CDI player) in which the plurality of processing operations to be executed (sync separation, subcarrier regeneration, color decoding, teletext) is executed by a central processing unit (4). Each processing operation is stored in the form of a control program in a memory (10). The processing operations to be actually executed are selected and time-sequentially executed by the processing unit. The control programs to be executed are selected in dependence upon operating signals (TXT, PIP) or signal recognition (PAL, NTSC). Qualitatively different versions of some control programs are stored and the version which can be executed at the available processing capacity is selected.
