Patent ID: 7630781

Claim:
A media data reproduction method, implemented in an embedded system comprising a media reader, a music player, a storage device, and a converter, comprising: receiving a reproduction request; automatically copying media data from storage media read by the media reader to the storage device in response to the reproduction request; converting, by the converter, the copied media data in the storage device to a new format; detecting system resources of the embedded system occupied by one or more modules other than the converter during conversion; and dynamically adjusting the workload of conversion based on the detected system resources to ensure that system resources utilized by the converter do not exceed system resources unused by the music player, wherein the detected system resources correspond to a plurality of levels comprising high, middle, and low levels, further comprising: when utilization information of the processor or Direct Memory Access (DMA) buffer satisfies parameters of the high level, determining that the detected system resources correspond to the high level, conversion of copied media data is suspended.
