1. A method for ensuring a storage time for digital broadcast at the time of storing broadcast data transmitted in a state of being digitized and compressed, comprising the steps of:

  • monitoring a predetermined recording time for the broadcast and a bit-rate of the broadcast in the compressed state and calculating, in real time, a required capacity of a storage medium;

    determining whether or not said calculated required capacity of the storage medium can be contained within an empty area or a freely limited area of the storage medium;

    if said calculated required capacity of the storage medium cannot be contained as the result of said determination, converting, in real time, said bit-rate of the broadcast into a smaller one by decoding and then re-compressing the broadcast data in the compressed state; and

    storing said converted broadcast in said storage medium.
