Patent Images
1. A video/audio media player supporting various flash memory cards, comprising:
- a CF Card Socket;
receiving a CF Card;
a combined socket, identifying/accessing multi flash memory cards inserted;
a microprocessor, supporting the flash memory cards in the combined socket to identify the system interface (CF Interface or IDE Interface) so that if a CF interface is detected, the arbitration switch will switch to the microprocessor so as to control the data exchange between the CF Card and the CF transfer interface and if an IDE Interface is detected, the arbitration switch will switch to the DSP so as to serve as the controller;
a Video Encoding Unit, being connected to the DSP and receiving video signals to output analog video/audio signals; and
an audio decoding unit, being connected to the DSP and receiving audio signals to output analog audio signals.
