Frame compatible format (FCF), which multiplexes the left and right eye views in to one frame spatially, has been considered as one of the most promising solutions for 3D video broadcasting. In this paper, a fast algorithm exploiting the content similarity is proposed to reduce the computational complexity for coding FCF. A low complexity average shift estimation method is proposed to find the matching blocks in the two inter leaved views, based on which mode candidate sets are designed for accelerating intra and interceding of the second inter leaved view (the inter leaved view at the bottom/right in FCF)by exploiting inter-view correlations. The proposed algorithm achieves an average of 72.45% reduction in Intra coding complexity and an average of 81.08% reduction in Inter coding complexity for the second inter leaved view, respectively, with negligible loss in compression efficiency. By combining with conventional fast algorithms, that is applying an conventional fast algorithm to code the view on the top/left and the proposed one to code the view on the bottom/right,the whole encoder provides up to 5.44 times higher encoding speed relative to applying the conventional algorithm solely to the whole frame with negligible performance degradation.

Recently, light emitting diode (LED) is the spot-light in the information technology and green technology industries. Visible Light Communication (VLC) system uses LED technology for illumination and data transmission at same time. Therefore, VLC system provides the environment of illumination to the user, which can provide the high quality multi-media service and various application services to the user. The main concerns of VLC systems are illumination and BER performance. Consequently, it is necessary to analyze the illumination control and method of transmit multimedia data in the VLC system. In this paper, we propose how to transmit effectively a video signal to RGB three-color LED while dimming and color controlling from the VLC system. In VLC System, LED can generate various colors of light by controlling the mixing ratio of each individual RGB color element. Thus, each RGB channel will have a different signal power, and each channel will have different performance. Therefore, we present a novel resource allocation using the RGB channels state information to allocate the video multi-layers in VLC system. The conventional system allocated the fixed channel to the Scalable Video Coding (SVC). However, the proposed system allocated the high priority of channel to the SVC signals. As a result, the proposed system can be improving the performance of BER than the conventional system following the simulation result.

Mobile communication data has evolved voice and text to multimedia data as music, picture and video etc., which requires high data rate and high quality of multimedia data. Multi-Carrier Code Division Multiple Access (MC-CDMA) has focused on the next generation communication system that can realize high data rate and large capacity mobile communication systems under multi-path fading environments. In conventional, it has considered about how to improve the performance of BER with efficient data usage. However, it does not consider about transmitting the cross layer as Scalable Video Coding (SVC) signal using MC-CDMA system. Scalable Video Coding (SVC) is composed one base layer and several enhance layers group. Each video layer has differential priority (Base layer>1st Enhance layer >2nd Enhance layer). In addition, conventional research has focused on the perfect CSI for video allocation. However, it is difficult to obtain perfect CSI in practical systems. Because the wireless channel state has time-varying characteristics. Moreover, if it obtained a perfect CSI, the feedback delay time will be increasing. As a result, the system is degraded the performance of BER by increased delay time. Therefore, we proposed the SVC signal transmission scheme using Transmission Block Selection (TBS) with partial channel state information (PCSI) in an MC-CDMA system. Proposed TBS scheme provides the base layer with the best protection by best performance sub-block selection. Enhance layer selected next best performance sub-block. The proposed system can improve the Peak Signal to Noise Ratio (PSNR) performance of the video communication compared to that of a conventional system.
