The transmission of video stream over wireless networks is used by many applications and services, from the use of equipment in home communication networks to those carrying the video surveillance stream. Numerous technical challenges may arise when the unpredictable characteristics of the radio channel align or do not align with the stipulated requirements for transmission bandwidth and the necessary latency for transporting video data. All these challenges prevent users from experiencing smooth video streaming. Depending on the application scenarios, video service emphasis may vary according of Quality of Experience - QoE or parameter used traditionally in the networks, Quality of Service - QoS. The purpose of the research consists in optimization of the flow service, which ensures the adaptability of video communication to changes of conditions over the wireless computer network. As a result of a thorough analysis of the video playback characteristics related to the wireless channel, the most optimal approach in optimizing the quality of the video stream service over a wireless LAN requiring minimal modifications was identified, and namely system centric approach.

“…Considering the coding performance of intra coding, a structure similarity (SSIM) based game theory approach was introduced in [19] to optimize the CTU level bit allocation. Similarly, a ρ domain bit allocation and a rate control algorithm were proposed in [20] to optimize bit allocation for key frames. Recently, the authors in [21] presented a highly parallel hardware architecture for rate estimation in HEVC intra coding.…”

“…Recently, the authors in [21] presented a highly parallel hardware architecture for rate estimation in HEVC intra coding. Although the aforementioned rate control algorithms [14][15][16][17][18][19][20] show promising performance for HEVC, their high computational complexity may not suitable for a number of emerging video applications. The HEVC DPB also contains two lists, list 0 and list 1, which are referred through the reference picture index.…”

The High Efficiency Video Coding (HEVC) standard has now become the most popular video coding solution for video conferencing, broadcasting, and streaming. However, its compression performance is still a critical issue for adopting a large number of emerging video applications with higher spatial and temporal resolutions. To advance the current HEVC performance, we propose an efficient temporal rate allocation solution. The proposed method adaptively allocates the compression bitrate for each coded picture in a group of pictures by using a trellis-based dynamic programming approach. To achieve this task, we trained the trellis-based quantization parameter for each frame in a group of pictures considering the temporal layer position. We further improved coding efficiency by incorporating our proposed framework with other inter prediction methods such as a virtual reference frame. Experiments showed around 2% and 5% bitrate savings with our trellis-based rate allocation method with and without a virtual reference frame compared to the conventional HEVC standard, respectively.

“…According to the previous analysis, it is known that the target bit allocation in the GOP layer rate control of the results obtained in previous research is unreasonable. The problem with MV-HEVC bit rate control is that it is difficult to allocate bits between viewpoints, and it is impossible to assign a reasonable bit to each viewpoint accurately [30]. The weight, k w , represents the proportion of all viewpoints from viewpoint k .…”

Three-dimensional (3D) video scenes are complex and difficult to control, especially when scene switching occurs. In this paper, we propose two algorithms based on an incremental proportional-integral-derivative (PID) algorithm and a similarity analysis between views to improve the method of bit allocation for multi-view high efficiency video coding (MV-HEVC). Firstly, an incremental PID algorithm is introduced to control the buffer "liquid level" to reduce the negative impact on the target bit allocation of the view layer and frame layer owing to the fluctuation of the buffer "liquid level". Then, using the image similarity between views is used to establish, a bit allocation calculation model for the multi-view video main viewpoint and non-main viewpoint is established. Then, a bit allocation calculation method based on hierarchical B frames is proposed. Experimental simulation results verify that the algorithm ensures a smooth transition of image quality while increasing the coding efficiency, and the PSNR increases by 0.03 to 0.82dB while not significantly increasing the calculation complexity.
