Abstract:
1. An electronic device, comprising: a multimedia play unit; and a processor, receiving a multimedia sequence, acquiring a first bit-rate of a first frame header from the received multimedia sequence, predicting a first length of a first frame comprising the first frame header by a formula employing at least parameters comprising the first bit-rate and a proportion of a second length to a second bit-rate of a second frame header prior to the first frame header; searching a synchronous pattern within a first search region comprising a position of a start position of the first frame header plus the predicted first length to identify a start position of a third frame header next to the first frame, updating the first length as a length between the start positions of the first frame header and the third frame header, and directing the multimedia play unit to play frame data of the first frame according to the predicted first length of the first frame.
