Abstract

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.

Claims

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; and

a removable flash memory device, coupled to the 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 a multimedia content file; and

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 an operating system utilized by the electronic system; and

code for use in controlling whether the decoder software and decryption software will or will not decode or decrypt the first data set.

2. The electronic system of claim 1, wherein the electronic system is a handheld electronic device.

3. The electronic system of claim 1, wherein the electronic system is a handheld electronic device having a wireless interface and a display.

4. The electronic system of claim 1, wherein the use in the electronic system includes displaying content in the multimedia content file on a display of the electronic system.

5. A method of operating an electronic system having a processor and memory storing operating system software that is executable by the processor, the method comprising:

receiving a removable flash memory device at an interface, the removable flash memory device having stored thereon;

a first data set in a first encoded format, the first data set including a multimedia content file; and

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 an operating system utilized by the electronic system;

executing the second data set, in conjunction with the operating system software, to produce the first data set in the second decoded format for use in the electronic system, including comprising code to determine whether the decoder software and decryption software will or will not decode or decrypt the first data set.

6. The method of claim 5, wherein the second data set includes an autoload program that is executable by the processor and is compatible with the operating system software.

7. The method of claim 5, further comprising:

storing a first code associated with the removable memory device on the removable memory device, separate from the first data set and the second data set; and

storing a second code in the first data set or the second data set, wherein executing the second data set includes comparing the first code to the second code.

8. The method of claim 7, including preventing execution of at least one of the decoder software and decryption software if the first code does not match the second code.

9. The method of claim 5, wherein the use in the electronic system includes displaying content in the multimedia content file on a display of the electronic system.
