System for transcoding media file to generate transcoded media file in media device, has transcode manager to instruct respective transcoders receiving divided segments to converge parameter to final quantization parameter

摘要

The system has a memory (112) for storing a media file (121), and a transcode manager (123) to divide the media file into multiple segments and to send respective segments to respective transcoders to generate corresponding output segments. The transcode manager is designed to instruct the respective transcoders receiving the divided segments to converge respective quantization parameter (QP) to approximately a predetermined final QP, where the predetermined final QP comprises a predetermined QP range or a predetermined QP value. An independent claim is also included for a method for transcoding a media file to generate a transcoded media file.
