Abstract

Interface apparatus is provided for enabling a digital video recorder to function as a universal data recorder. A random input data stream provided at a first data rate is converted to a format that emulates a video signal. The converted input data is input, at a video signal data rate, to a digital video recorder for storage. The stored converted data is played back from the video recorder at the video signal data rate. The retrieved data is then converted back to the original format of the input data stream at the first data rate.
