Multimedia storage systems and methods

摘要

An article of manufacture includes a machine-readable medium that stores a multimedia content file in a first format and multiple program sets. Each program set is a version of software that, when executed by a respective electronic system, produces the multimedia content file in a second format for use in the respective electronic system. A first program set is compatible with a first operating system executed by a first electronic system and a second program set is compatible with a second operating system executed by a second electronic system. The second operating system is distinct from the first operating system.

主权项

1. An electronic system, comprising:
a first processor; memory coupled to the first processor; operating system software stored in the memory and executable by the first processor to display a menu of multimedia content stored in a multimedia content file; and a removable flash memory device, coupled to the first processor by an interface, the removable memory device having stored thereon:
a first data set in a first encoded format, the first data set including the multimedia content file;a second data set, which when executed by a processor in an electronic system produces the first data set in a second decoded format for use in the electronic system,wherein the second data set includes decoder software and decryption software for decoding and decrypting the first data set, and an autoload program that is executable by the processor and is compatible with the operating system software; a first code stored on the removable memory device, separate from the first data set and the second data set, to identify the removable memory device; and a second code in the first data set or the second data set, wherein the second data set, when executed by the processor, compares the first code to the second code, wherein the removable flash memory device includes a code stored in a register included in the removable flash memory device and linked to the first and second data sets, such that if the code stored in the register does not correspond to a code linked to the decoder software and decryption software of the second data set, the decoder software and decryption software will not decode or decrypt the first data set.
