In this paper, we evaluated stereoscopic video performance transmitted through wireless channel. Human’s visual perception capabilities of two eyes are different and one of two eyes is predominant one for visual perception. Thus using this human visual characteristic, there is no problem to recognize the 3D perception even if we sent relatively low quality of one of two video information for reducing the amount of data. If we use the constituting gain channel with Gray mapping for hierarchical 16-QAM (Quadrature Amplitude Modulation) called as (16-HQAM), we allocated the predominant video compressed data using H.264/AVC(Advanced Video Compression) to high gain channel and the compressed data of the other side video to low gain channel and send them. The simultaneously compressed video information of two views is sent through AWGN(additive White Gaussian Noise) channel environment. Controlling the channel gain, we discuss PSNR(Peak Signal to Noise Ratio) and CDF(Cumulative Distribution Function) performance. |
