Studying the Effect of Changes in Video Streaming Parameters to Enhance MPEG Performance Quality
Riad, Mazhar B. Bassiuony, Ashraf A. Taha, Mary Z. . 2013
The video quality and compression ratio depends on the GOP pattern structure (i.e. the I, P and B-frames). This paper studies the impact of using different values for Frame Rate on GOP structure with respect to the number of consecutive maximal count of B-frame sequences to reach a better video quality . A MATLAB code MPEG-2 algorithm was used to model and assess this effect. The assessment test was implemented using three types of reference videos: Foreman, News, and Football sequences in (YUV video repository). The Simulation Results show that using more B-frame sequences than that studied in previous work, with respect to Frame Rate (FR) causes an improvement in Video Quality (PSNR) irrespective to type of video Motion.

For real-time transmission, still image and video sources require wide bandwidths and large storage memory space. Therefore, compression techniques are useful and must be applied to overcome the…
The demand for video streaming has been soaring in recent years. However, there is a gap between traffic demand and link capacity due to time-varying throughput fluctuation. This fluctuation…
