Abstract: A system processes a video signal that includes a plurality of signal components representing respective ones of a plurality of video programs such as various pay-TV programs. Each of the signal components is processed, e.g., descrambling a pay-TV program, by one of a plurality of series connected high speed signal processing integrated circuit (IC) cards, or "smart" cards. An output signal from the last smart card in the series connection includes a plurality of processed signal components. The plurality of processed signal components are processed further to produce a signal suitable for producing a displayed image that includes multiple image portions, such as a picture-in-picture (PIP) or picture-outside-picture (POP) image in a television system. Each portion of the image is produced in response to one of the processed signal components.
