| dc.description.abstract | H.264/AVC provides an interface for flexible, bandwidth-optimized transmission of broadcast video streaming in Long Term Evolution (LTE) network. The videa quality and compression ratio depends on Group of Pictures (GOP) structure. GOP structure also affects the distortion sensitivity of the video stream due to packet losses. In this paper, the effect of the GOP length to the video quality is investigated. The simulation results show that by increasing the GOP length, the video quality also increases. But after reaching the highest PSNR (Peak Signal to Noise Ratio) or MOS (Mean Opinion Score) value, it starts to decreate. In the first increasing period, the efficient coding plays major role, so higher of GOP lengths lead to a better quality. After the optimal of GOP settings, when the video quality is the highest, the error propagation effect becomes more significant. Hence, using higher, the error Intra frame (I-frame) intervals, the error will be spreading because of significant distortion. Each type of transmitted video has different optimal GOP, defend on its characteristic. For four types of reference videos that are used in the simulation, the optimal GOP is reached at 5 ≤ GOP length ≤ 8. | en_US |
