US 2011/0255590 A1 · DATA TRANSMISSION APPARATUS AND METHOD, NETWORK DATA TRANSMISSION SYSTEM AND METHOD USING THE SAME

Abstract

Disclosed herein are a data transmission apparatus and method, and a network data transmission system and method using the same. A data transmission method according to an exemplary embodiment of the present invention encodes photographed images to generate image live data and generates image analyzing data based on the photographed images. Thereafter, the data transmission method calculates the network transmission bandwidth and stores image live data as image preserving data simultaneously with transmitting the image analyzing data when the network transmission bandwidth is smaller than the predetermined threshold value. If it is determined that the network transmission bandwidth is larger than a predetermined threshold value, the data transmission method transmits the image live data or transmits the image analyzing data and/or the image preserving data along with the image live data.
