<p>PROBLEM TO BE SOLVED: To prevent the deterioration in an image by avoiding the compression rate of the MPEG system from being decreased more than a prescribed rate in a data converter that converts an image signal subjected to compression processing by the DV system into an image signal of other data system such as the MPEG system and a signal processing system for a data processor that applies compression processing to the image signal and an audio signal processed with the MPEG system. SOLUTION: The information signal processor is provided with a signal detection means detecting that a prescribed information signal received from a prescribed input means is a signal of a 1st signal system, a signal conversion means that converts the prescribed information signal into a signal of a 2nd signal system by selecting a prescribed attribute among a plurality of attributes possible for setting, and a setting control means that controls the conversion means not to apply the prescribed attribute among a plurality of the attributes to a default setting as its conversion of the signal system when the signal detection means detects that the information signal received from the input means adopts the 1st signal system.</p> |
