Abstract

A television receiver configured for a 16:9 display format is also compatible with different transmissions based upon a 4:3 format. Standard PAL signals can be transmitted with so-called letter box strips. Letter box lines can be used to identify the different possibilities, namely, standard signals without letter box information, no letter box signals, letter box signals from film sources and those from camera sources. The identification coding can be contained within the FBAS signal using the period (15) following the burst signal (12) and before the picture signal is generated (13).
