Abstract: A method of providing a PIP on a display screen of, or connected to electrical apparatus, such as a broadcast data receiver or set top box. The method includes the steps of horizontally scaling the PIP using hardware 12 provided in the electrical apparatus, transferring the horizontally scaled PIP to memory 10 in the processor of the apparatus, the PIP being vertically scaled in the memory of the processor before being transferred to the graphics plane of the display screen. The method eliminates the need for external memory in the electrical apparatus.
