| 1. A digital broadcasting receiving and recording apparatus comprising:
means for receiving a digital broadcasting wave to extract a program stream;
means for recording the program stream on a built-in recording device;
means for recording the program stream on an external recording device using an interface for transmitting and receiving data
and control information to and from the external recording device; and
means for judging whether the program stream can be recorded on the external recording device on the basis of the control
information provided from the external recording device;
wherein the apparatus is arranged to switch automatically so as to record the program stream with the built-in recording device
instead of the external recording device if it is judged before and during recording on the external recording device that
such recording cannot be performed, and
wherein, when a part of the program stream is recorded on the built-in recording device because a remaining capacity of the
external recording device is insufficient, a reproduction is executed in the external recording device to record a reproduced
partial program stream to the built-in recording device before dubbing the program stream from the built-in recording device
to the external recording device.
