Embodiment Construction
[0032] The present invention provides a data processing method and system, in which mechanisms such as pre-processed cache entry, shared cache pool and incremental processing are proposed. In some embodiments, the data processing method and system are used to decode MPEG-4 files, which have been clearly defined in the ISO standard, which is not intended to limit the present invention. An overview of the MPEG-4 file has been proposed in the standard specification of ISO14496-12, which can be combined for reference and description. Additionally, in some embodiments, the data processing method and system is used to decode MP3 data. The data processing method and system can be used to decode other kinds of audio data without metadata, such as AAC, AMR / AWB.
[0033] Preprocessed cache items:
[0034] First, decoding of MPEG-4 files using the data processing method and system will be described.
[0035] FIG. 4 shows items in an STTS box and their corresponding preprocessed cache ...
