Abstract
The main challenge of multimedia applications is how to transmission the Ultra-High Definition (UHD) video streaming in real time over the internet. The real time video streaming suffer from difficulties to be flexible and efficiency cause the wide variation of the available internet bandwidth. To avoid the problems that introduces with internet, in this work the HEVC with required video network adaptive streaming are proposed and tested using different six levels of three UHD video (4K, FHD, 720p, 4CIF, CIF and QCIF). From different experiments that applied find the optimal configuration of H.265 encoding features for six levels to obtain the required PSNR with range (32-38 dB). The important part in this project is a controller that worked incorporate with the encoder (H.265) to obtain the video streaming adaptation on the available bandwidth of the channel. The controller continuously reads the status of channel buffer, then choosing the proper level of video to be transmitted over the channel. The work architecture is content two parts: First, the H.265 codec that apply on the three raw videos with optimal parameters configuration to compress them and get videos with lower bit rate and acceptable quality. Second, the compressed videos, based to controller.....
Highlights
The increased use of video streaming with different resolutions for several kinds of terminal devices like mobile, tablet, PCs and High Definition TV (HDTV), and the diversity of services with the growing popularity of higher quality Ultra-High Definition (UHD) video in these device applications are the main challenges of multimedia providers [1]
While the controller is incorporated with this encoder to achieve the video streaming adaptation on the available bandwidth by selecting an appropriate layer at an assigned bit rate that is compatible with the channel and keeping a good quality for the end-users in the optimal state of the network
The maximum value of the total traffic for low details video is reached to 10 Kb/s, while the medium details are reached to 16 Kb/s as shown in Fig. 7, but with the high details is reached to 80 Kb/s
Summary
The increased use of video streaming with different resolutions for several kinds of terminal devices like mobile, tablet, PCs and High Definition TV (HDTV), and the diversity of services with the growing popularity of higher quality UHD video in these device applications are the main challenges of multimedia providers [1]. These challenges make the compression techniques with H.265/HEVC encoders is the way to get the better of the traffic bandwidth load balancing [2]. The used streaming technique is based on the technique used in [5]
