This invention relates in general to a portable electronic apparatus comprising in the same microchip a digital processor with cryptography means a large capacity flash memory and a digital signal processor (FIG. 1 ) which is entirely embedded into a smart card. This said portable electronic apparatus comprises a digital processor ( 1 ) linked directly ( 17 ) to a large capacity flash memory ( 2 ), this said memory ( 2 ) linked directly to a digital signal processor (DSP) ( 3 ). This said portable electronic apparatus comprises a direct link ( 19 ) between the said digital processor ( 1 ) and the said digital signal processor ( 3 ). This said portable electronic apparatus comprises a signal switch ( 4 ) driven by a signal ( 11 ) which, according to its value, establishes a contact between the numerical signals ( 13, 14 ) with the contacts ( 10, 12 ), or a contact between the analog signals ( 15, 16 ) with the contacts ( 10, 12 ). This invention concerns particularly the deciphering and storage of encrypted music and video pieces, and the rendering, directly as analog signal of the said music and video pieces, directly amplifiable by common music or video players.
