  • Media data reproduction methods and embedded systems utilizing the same
    Patent number: 7630781
    Abstract: A media data reproduction method is implemented in an embedded system comprising a media reader, a storage device, and a converter. First, a reproduction request is received. Media data is automatically copied from storage media read by the media reader to the storage device in response to the reproduction request. The converter converts the copied media data in the storage device to a new format. During conversion of the copied media data, system resources of the, embedded system occupied by modules other than the converter are detected. The workload of converting the copied media data is dynamically adjusted based on the detected system resources to ensure that system resources utilized by the converter do not exceed system resources unused by modules other than the converter.
