A method and apparatus for transferring protected digital AV content. The apparatus 10 includes a specially adapted microprocessor 12 with firmware allowing the microprocessor to control and transmit for storage and for display device 14 digital AV content data in the form of digital signals. A source storage device is connected to the microprocessor 12 by means of link 26. At least one sink storage device 20 is also connected to microprocessor 12 by link 28. The firmware allows the microprocessor to time the amount of material transferred to sink 20 to that allowed by the appropriate copy protection specification. The method limits the amount of data transferred to the programmed amount for example one second slices ending on a frame end. After each increment of data is transferred the amount remaining on source 16 is deleted. The process continues until all of the desired material is transferred from source 16 to sink 20.
