Abstract: Representative implementations of devices and techniques provide a modulation arrangement for a control signal. The control signal is received as a digital value. A modulated control signal having a varying rate of change may be generated based on the quantity of off-bits and the quantity of on-bits of the digital value.

Abstract: In the case of picture insertions, such as picture-in-picture, for example, fluctuations in the line duration are manifested in position displacements relative to the desired position of the inserted pictures. In order to prevent position displacements in the horizontal direction, it is provided that the insertion position is corrected in a manner dependent on a determined line duration. The method according to the invention is suitable in particular for picture-in-picture insertions in television receivers.

Abstract: In display apparatuses, particularly television receivers and monitors, a video picture can be inserted into a main picture (HB) from a first video signal (VS1), in which a second picture (ZB) from a second video signal (VS2) has a first picture format and is composed of picture lines (BZ) and filling lines (FZ). The picture lines (BZ) forming a sub-picture (UB) with the second picture format is adjoined by the filling lines (FZ) in the vertical picture direction. The second picture format of the sub-picture (UB) is determined and the determined second picture format is used for determining the filling lines (FZ). The picture lines (BZ) and a portion of the filling lines (FZ) are inserted as an insertion picture into the main picture (HB). Additional insertions (OSD) from an additional signal, which at least partly lie within the filling lines (FZ), is displaced into the sub-picture (UB).

Abstract: A method for producing a frame around a video image includes the step of placing subframes around a base frame. The subframes have an offset with respect to the base frame, in order to generate a plastic impression of the frame. The base frame and the subframes are produced from the same frame signal. A device for producing such a frame is also provided. The method and the device are in particular used in picture-in-picture systems.
