We propose a novel technique to synchronize elemental images and audio signal and the transmission technique for aglass-free 3D TV system based on integral imaging. The main idea behind the method is to generate 3D video based onelemental images synchronized with audio stream. The system uses the depth information and RGB data of per frame ofa video through Intel RealSense 3D camera and the audio stream from microphone. The audio file is sampled accordingto per frame duration of the video and kept in different buffers but having same index. The frames are divided intoelemental images using Elemental Image Generation algorithm and the audio signal is synchronized according to theindex. Then the stream of elemental images and corresponding audio data is transmitted to data server for storage. HLSstreaming protocol is used to stream the TV content. A dedicated web application was made that fetches data from theserver and plays video on the user end display device. By using array of micro-lenses in front of display, the video isviewed as three-dimensional with the help of integral imaging technology that omits the need of wearing 3D glasses.
