A content distribution system stores encrypted content, an operating system, a decrypt application and a decrypt key on a portable storage device with a serial communication interface such as USB. The portable storage device may be connected to a hardware unit (containing a corresponding/compatible serial interface) designed to boot from the stored operating system. Upon booting, the operating system automatically retrieves the encrypted content, decrypt application and decrypt key, and executes the decrypt application to generate (by decrypting using the decrypt key) the source content, which is then reproduced/replayed on a suitable system such as a television. Content such as songs/movies etc., may thus be distributed efficiently on a relatively small-sized portable storage devices such as a USB thumb drive. |
