METHOD AND SYSTEM FOR SYNCHRONIZING MOBILE MULTIMEDIA BROADCASTING AND SUBTITLES

摘要

A method and a system for synchronizing mobile multimedia broadcasting and subtitles. The method comprises: receiving a subtitle data packet sent by a subtitle server and an audio subframe sent by an audio coder; obtaining the start time of audio play from the audio subframe; obtaining a subtitle from the subtitle data packet; determining the time offset of the subtitle relative to the start time of audio play; when encapsulation time is up, encapsulating character strings of the subtitle, the start time of audio play and the time offset of the subtitle relative to the start time of audio play into a data segment of the audio subframe corresponding to the subtitle; and sending the data segment to a mobile multimedia broadcasting terminal.
