ABSTRACT:
When the low bit rate coding is effected in a recording system 1A, a signal is coded and recorded in a hierarchical structure. On the reproduction side, the type of a recorded signal (the low bit rate coded signal of the hierarchical structure, non-hierarchical structure, conventional analog recording or the like) is determined by a determination system 1E and the operation modes of a digital signal processing system 1G and an analog signal processing system 1F are set. The analog signal processing system processes a reproduced signal when it is analog signal. The digital signal processing system processes a reproduced signal when it is a digital signal or when a reproduced output from the analog signal processing system is processed in a digital manner. Further, hierarchical decoding G30 and inverse converting G40 are provided, a signal processed in the hierarchical structure can be restored to an original form, and the restored reproduced signal can be processed by use of system conversion G60 and converted to a desired system and output. As a result, various types of input video signals can be recorded in a preset form and various forms of recorded video signals can be reproduced and output in a desired form. Further, an analog recorded signal can be reproduced and output after converted to a desired form.
