Abstract

A method for processing trip information and dynamic data streams are provided, and includes the following steps. (1) A dynamic data stream including a plurality of video frames is received. (2) Plural batches of trip information are received. (3) At least one batch of trip information and at least one corresponding video frame of the dynamic data stream are taken to construct trip video data. Therefore, when a user playbacks the trip video data, the user can simultaneously see the video frame and obtain the corresponding trip information thereof.
