USB interface
The USB interface is used for the three following functions:
Features
PC download from the camera of all the various objects stored on the mass storage media. The
STV0684 uses mass storage class, Bulk-only-transfer to ensure seamless connection with most
of the current operating system from the market, including PC and Macintosh platforms.
Stream concurrent audio and video through isochronous endpoints. The STV0684 uses
established and newly developed standards to ensure the lowest burden of driver development.
The STV0684 is compliant with both USB audio and video classes.
Download the system program code necessary to run the application either in a serial flash or in
a NAND flash soldered on the main camera PCB. This convenient function permits the
programming of cameras on the manufacturing lines, it is not open to final users.
