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).

Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass die Nutzinformationsdaten derart gesendet werden, dass von jedem Datenpaket seine nicht-invertierte und invertierte Signalform sequentiell übertragen wird und dass empfangsseitig zur Feststellung von Übertragungsfehlern zu jeder invertierten Signalform die zugehörige nicht-invertierte Signalform addiert (52) wird, wobei eine resultierende Signalsumme ungleich Null einen Übertragungsfehler indiziert.Method according to Claim 1, characterized in that the payload information data are sent in such a way that its non-inverted and inverted signal form is transmitted sequentially from each data packet and that the associated non-inverted signal form is added to the receive side for determining transmission errors for each inverted signal waveform ( 52 ), with a non-zero sum of the signal indicating a transmission error. Verfahren nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass die Nutzinformationsdaten in Form mehrerer Datenpakete strukturiert sind.A method according to claim 1 or 2, characterized in that the Nutzinformationsdaten are structured in the form of several data packets. Verfahren nach einem oder mehreren der Ansprüche 1 bis 3, dadurch gekennzeichnet, dass die Einlaufinformationsdaten Sinusschwingungen enthalten.Method according to one or more of claims 1 to 3, characterized in that the inlet information data sinusoids. Verfahren nach einem oder mehreren der Ansprüche 1 bis 4, dadurch gekennzeichnet, dass die Nutzinformationsdaten mit erhöhter Redundanz übertragen werden.Method according to one or more of claims 1 to 4, characterized in that the Nutzinformationsdaten be transmitted with increased redundancy. Verfahren nach einem oder mehreren der Ansprüche 1 bis 5, dadurch gekennzeichnet, dass das Nutzinformationsdaten-Signal gleichspannungsfrei ist.Method according to one or more of claims 1 to 5, characterized in that the Nutzinformationsdaten signal is DC-free. Verfahren nach Anspruch 6, dadurch gekennzeichnet, dass die Nutzinformationsdaten biphasecodiert sind.A method according to claim 6, characterized in that the Nutzinformationsdaten are Biphasecodiert.
