The digital signal recording/reproducing apparatus inputs a digital signal having a control flag as to a temporary copy permission, and records the digital signal temporarily into a recording medium in accordance with conditions in the control flag, then reproducing the digital signal temporarily from the recording medium in accordance with the conditions in the control flag. The recording/reproducing of the temporary copy is permitted, depending on the following conditions: The recording medium's type, the re-producing point-in-time, the reproducing time-period, and the reproducing frequency. With this method employed, even in a program permitting no recording, the temporary recording/reproducing is permitted under a condition of being limited to the time-shift recording on the receiving side.
