An information recording and playing back system and method thereof, in which a dubbing can be performed during a normal recording and playing back state without a user recognizes a transferring rate that changes in a recording and playing back state of recording and playing back apparatuses, are provided. The information recording and playing back system provides a first recording and playing back apparatus that can record audio sounds and video images (AV) information from tuners and can play back recorded AV information for external output terminals and a second recording and playing back apparatus being a low speed apparatus such as a DVD-RAM, and performs a dubbing of AV information from the first recording and playing back apparatus to the second recording and playing back apparatus. The system further provides a comparator that compares usable transferring rates of the first and second recording and playing back apparatuses and outputs a slower transferring rate. The dubbing of the AV information is performed by controlling a transferring speed of the AV information corresponding to the slower transferring rate.
An information recording and playing back system, which provides a first recording and playing back apparatus that can records and play back audio and video (AV) information of plural channels at the same time and a second recording and playing back apparatus, which is built-in or set outside said system, can record and play back said AV information from said first recording and playing back apparatus, can perform dubbing of required AV information from said first recording and playing back apparatus to said second recording and playing back apparatus, comprising:
An information recording and playing back method, in which dubbing of a required AV information is performed from a first recording and playing back apparatus that can records and play back AV information of plural channels at the same time to a second recording and playing back apparatus that can record and play back AV information, comprising the steps of:
