Abstract: An intelligent streaming media error check detection method and apparatus. The claimed invention discloses an apparatus and method where all streaming media are initially assumed to have compatible error checksums. A parameter W is initialized to zero. The parameter W is not constant and conceptually represents a state of the error check method. The destructive value of a first predefined constant is added to the parameter W each time the acceptability of a data set cannot be verified. The constructive value of a second predefined constant is subtracted from the parameter W each time the acceptability of a data set is successfully verified. If the value of the parameter W equals or exceeds a predefined threshold, the remainder of the streaming media is decoded and played without error check protection.

Abstract: Input buffer management of the playback control for MP3 players includes initializing a totalizer to zero, finding a synchronization word of a frame, decoding a header, calculating the size of a main_data field, and decoding the enclosed audio data. If it is determined the value contained in the totalizer is less than the main_data_begin of this frame, store the main_data of the frame in an input buffer, add the size of the main_data to the totalizer, and repeat the process starting with finding the synchronization word of a next frame until the totalizer is greater or equal to the main_data_begin of the then current frame. At this point, all of the audio data required by the frame is currently available and decoding and playing can continue as normal.
