Inserting one or more video pictures by combining encoded video data before decoding

An arrangement for insetting a moving secondary picture in a moving main picture, wherein signals of said pictures are in an encoded digital format, the arrangement comprising:

• means (230) for scaling down an individual frame in the secondary picture by reducing a number of macro blocks included in each individual frame of the secondary picture and combining a resulting scaled-down frame with a frame of the main picture for providing combined frame code, and
• a decoder (210) for decoding the combined frame code into a video signal.

A receiver comprising:

• a combiner (230) for insetting a moving secondary picture in a moving main picture using scaling down of the secondary picture by reducing a number of macro blocks included in each individual frame of the secondary picture, responsive to at least two signals in a digital format for providing an output signal (CS), wherein said at least two signals represent the main picture and the at least one secondary picture, respectively, and
• a decoder, responsive to said output signal, for providing a decoded output signal for simultaneously displaying at least two pictures corresponding to said at least two video signals.
