1. A system of controlling playback of a digital media file in a device, the system comprising: a processor; anda memory communicatively coupled to the processor, the memory having computer-executable instructions that when executed by the processor, perform a method of controlling playback of the digital media file in the device, the method comprising: reading, at the device, a license, stored on the device, the license specifying an output protection level that identifies an output type from among a plurality of discrete output types, the identified output type being defined for a playback output function and comprising a first numerical value that is a minimum bar configured to control the playback output function of the digital media file over an output path of the device;determining, at the device, a media type of the digital media file, wherein the media type of the digital media file comprises a second numerical value;comparing, at the device, whether the second numerical value of the media type of the digital media file exceeds the first numerical value that is the minimum bar configured to control the playback of the digital media file over the output path of the device; andwhen the second numerical value of the media type of the digital media file exceeds the identified output type comprising the first numerical value, playing back, at the device, the digital media file over the output path. 2. The system of controlling playback of the digital media file of claim 1, further comprising a policy engine for applying the specified output protection level to control the playback of the digital media over the output path. 3. The system of controlling playback of the digital media file of claim 1, further comprising an external component coupled to the output path of the device. 4. The system of controlling playback of the digital media file of claim 3, in which the external component is a video display. 5. The system of controlling playback of the digital media file of claim 3, in which the external component is a speaker. 6. The system of controlling playback of the digital media file of claim 3, in which the output path is digital uncompressed video. 7. The system of controlling playback of the digital media file of claim 3, in which the output path is digital compressed video. 8. The system of controlling playback of the digital media file of claim 2, wherein the first numerical value is an even numerical value. 9. The system of controlling playback of the digital media file of claim 1, in which the license is rendered in extensible markup language XML. 10. The system of controlling playback of the digital media file of claim 1, in which the license is rendered in binary. 11. A computer-implemented method of controlling playback of a media file in a device, executed by a processor, the computer-implemented method comprising: receiving, at the device, a license from a service provider for controlling playback of the media file, wherein the license specifies a first output protection level associated with a first predetermined media type from one of a plurality of output configurations having comparable security and functionality, the first predetermined media type comprising a first numerical value that is a minimum bar configured to control the output function of the media file;determining, at the device, a media type of the media file, the media type of the media file comprising a second numerical value;determining, at the device, whether the second numerical value of the media type of the media file matches or exceeds the first numerical value of the first predetermined media type specified by the license; andwhen the second numerical value of the media type of the media file matches or exceeds the first numerical value of the first predetermined media type specified by the license, using the first output protection level to determine, at the device, that the media file should be output to an output path according to the output configuration associated with the first predetermined media type and specified by the output protection level in the license; andoutputting, at the device, the media file over the output path. 12. The computer-implemented method of controlling playback of a media file in the device of claim 11 wherein the predetermined media type is one of the following: digital compressed audio, digital uncompressed audio, digital compressed video, and digital uncompressed video. 13. The computer-implemented method of controlling playback of a media file in the device of claim 12 wherein the license has a second security level associated with a second predetermined media type and the method further comprises: when the second numerical value of the media type of media file does not match or exceed the first numerical value of the predetermined media type in the license, determining, at the device, whether the second numerical value of the media type of the media file matches or exceeds a numerical value of the second predetermined media type in the license; andwhen the second numerical value of the media type of the media file matches or exceeds the third numerical value of the second predetermined media type in the license, using the associated second security level to determine, at the device, whether to output the media file over the output path. 14. A computer-readable storage device including instructions that, when executed by a processor, perform a method of controlling playback of a media file in a device, the method comprising: receiving, at the device, a license from a service provider for controlling playback of the media file, wherein the license specifies a first output protection level associated with a first predetermined media type from one of a plurality of output configurations having comparable security and functionality, the first predetermined media type comprising a first numerical value that is a minimum bar configured to control the output function of the media file;determining, at the device, a media type of the media file, the media type of the media file comprising a second numerical value;determining, at the device, whether the second numerical value of the media type of the media file matches or exceeds the first numerical value of the first predetermined media type specified by the license; andwhen the second numerical value of the media type of the media file matches or exceeds the first numerical value of the first predetermined media type specified by the license, using the first output protection level to determine, at the device, that the media file should be output to an output path according to the output configuration associated with the first predetermined media type and specified by the output protection level in the license; andoutputting the media file over the output path. 15. The computer-readable storage device of claim 14 wherein the predetermined media type is one of the following: digital compressed audio, digital uncompressed audio, digital compressed video, and digital uncompressed video. 16. The computer-readable storage device of claim 15 wherein the license has a second security level associated with a second predetermined media type and the method further comprises: when the second numerical value of the media type of the media file does not match or exceed the first numerical value of the predetermined media type in the license, determining, at the device, whether the second numerical value of the media type of the media file matches or exceeds a third numerical value of the second predetermined media type in the license; andwhen the second numerical value of the media type of the media file matches or exceeds the third numerical value of the second predetermined media type in the license, using the associated second security level to determine, at the device, whether to output the media file over the output path.
