Patent ID: 7002635

Claim:
A method for inserting an inset picture (EB) into a main picture (HB) constructed from a plurality of lines, which is transmitted with a video signal (HVS) and in the case of which the construction of a new line of the main picture (HB) from pixels is begun when a start pulse (IP) is detected in the video signal (HVS), comprising: determining the time duration between two successive horizontal start pulses (IP) to determine an actual line duration of a line of the main picture, and after a specific number—dependent on the actual line duration determined and on a desired vertical position (WP) of the inset picture (EB) within the main picture (HB)—of pixels from the beginning of a line of the main picture (HB) that is provided for the insertion, a line of the inset picture (EB) is inserted within this provided line of the main picture (HB), wherein the specific number of pixels after which the insertion is effected is described by: b actual = b desired · T actual T nom where the following holds true: T actual is the actual line duration between the two successive horizontal start pulses, T nom is a nominal line duration (NZD) of a complete line of the main picture (HB), and b desired is the number of pixels from the beginning of a line of the main picture (HB) in the case of which the line of the inset picture (EB) would have to be inserted at the desired horizontal position (WP) in event of the time duration between the two successive horizontal start pulses being T actual =T nom .
