APPARATUS AND METHOD FOR MULTI-PASS ENCODING

摘要

A multi-path encoding apparatus and a method thereof are provided to shorten the time required for the multi-path encoding. The first encoder and an input delay unit receive the original image data at the same time(S300). The first encoder encodes the inputted image data and then sequentially stores the encoded result in a buffer(S310). A bit rate control unit sets up and stores the quantization coefficient to be applied to the second encoder(S320). The input delay unit outputs image data after a certain time elapses from the time when the firs frame of the original image data is inputted(S330). The second encoder applies the quantization coefficient stored in a memory to the quantization step to encode the inputted image data(S340).
