Improved HEVC Video Encoding Quality With Multi Scalability Techniques

Video content becomes very popular today and dominates internet traffic, and various efforts to design and implement QOS (Quality of Service) services are being carried out. During its transmission through network, there are lost packets and significant variations in the load on the bandwidth. Moreover, network congestion degrades the video data transmission rate. This study offers a new video encoding, namely HEVC (High-Efficiency Video Coding), with multi-scalability in its output, including SNR (Signal to Noise Ratio), spatial and temporal scalability. The results showed that the use of multi scalability techniques resulted in better performance than the single scalability indicated by the increase in the average PSNR (Peak Signal to Noise Ratio) in video quality.
