This thesis models the rate-distortion characteristics of an H.264 video compression encoder to improve its mode decision performance. First, it provides a background to the fundamentals of video compression. Then it describes the problem of estimating rate and distortion of a macroblock given limited computational resources. It derives the macroblock rate and distortion as a function of the residual SAD and H.264 quantization parameter QP. From the resulting equations, this thesis implements and verifies rate-distortion optimization on a resource-limited H.264 encoder. Finally, it explores other avenues of improvement.

Video content now occupies about 82% of global internet traffic. This large percentage is due to the revolution in video content consumption. On the other hand, the market is increasingly demanding videos with higher resolutions and qualities. This causes a significant increase in the amount of data to be transmitted. Hence the need to develop video coding algorithms even more efficient than existing ones to limit the increase in the rate of data transmission and ensure a better quality of service. In addition, the impressive consumption of multimedia content in electronic products has an ecological impact. Therefore, finding a compromise between the complexity of algorithms and the efficiency of implementations is a new challenge. As a result, a collaborative team was created with the aim of developing a new video coding standard, Versatile Video Coding – VVC/H.266. Although VVC was able to achieve a more than 40% reduction in throughput compared to HEVC, this does not mean at all that there is no longer a need to further improve coding efficiency. In addition, VVC adds remarkable complexity compared to HEVC. This thesis responds to these problems by proposing three new encoding methods. The contributions of this research are divided into two main axes. The first axis is to propose and implement new compression tools in the new standard, capable of generating additional coding gains. Two methods have been proposed for this first axis. These two methods rely on the derivation of prediction information at the decoder side. This is because increasing encoder choices can improve the accuracy of predictions and yield less energy residue, leading to a reduction in bit rate. Nevertheless, more prediction modes involve more signaling to be sent into the binary stream to inform the decoder of the choices that have been made at the encoder. The gains mentioned above are therefore more than offset by the added signaling. If the prediction information has been derived from the decoder, the latter is no longer passive, but becomes active hence the concept of intelligent decoder. Thus, it will be useless to signal the information, hence a gain in signalization. Each of the two methods offers a different intelligent technique than the other to predict information at the decoder level. The first technique constructs a histogram of gradients to deduce different intra-prediction modes that can then be combined by means of prediction fusion, to obtain the final intra-prediction for a given block. This fusion property makes it possible to more accurately predict areas with complex textures, which, in conventional coding schemes, would rather require partitioning and/or finer transmission of high-energy residues. The second technique gives VVC the ability to switch between different interpolation filters of the inter prediction. The deduction of the optimal filter selected by the encoder is achieved through convolutional neural networks. The second axis, unlike the first, does not seek to add a contribution to the VVC algorithm. This axis rather aims to build an optimized use of the already existing algorithm. The ultimate goal is to find the best possible compromise between the compression efficiency delivered and the complexity imposed by VVC tools. Thus, an optimization system is designed to determine an effective technique for activating the new coding tools. The determination of these tools can be done either using artificial neural networks or without any artificial intelligence technique

Power consumption for Systems-on-Chip induces strong constraints on their design. Power consumption affects the system reliability, cooling cost, and battery lifetime for Systems-on-Chips powered by battery. With the pace of semiconductor technology, power optimization has become a tremendous challenging issue together with Silicon area and/or performance optimization, especially for mobile applications. Video codec chips are used in various applications ranging for video conferencing, security and monitoring systems, but also entertainment applications. To meet the performance and power consumptions constraints encountered for mobile applications, video codecs are favorably preferred to be implemented in hardware rather than in software. This hardware implementation will lead to better power efficiency and real-time requirements. Nowadays, one of the most efficient standards for video applications is the H.264 Advanced Video Coding (H.264/AVC) which provides better video quality at a lower bit-rate than the previous standards. To bring the standard into commercial products, especially for hand-held devices, designers need to apply design approaches dedicated to low-power circuits. They also need to implement mechanisms to control the circuit power consumption. This PhD thesis is conducted in the framework of the VENGME H.264/AVC hardware encoder design. The platform is split in several modules and the VENGME Entropy Coder and bytestream Network Abstraction Layer data packer (EC-NAL) module has been designed during this PhD thesis, taking into account and combining several state-of-the-art solutions to minimise the power consumption. From simulation results, it has been seen that the EC-NAL module presents better power figures than the already published solutions. Then, the VENGME H.264 encoder architecture has been analyzed and power estimations at RTL level have been performed to extract the platform power figures. Then, from these power figures, it has been decided to implement power control on the EC-NAL module. This latter contains a FIFO whose level can be controlled via an appropriate scaling of the clock frequency on the NAL side, which leads to the implementation of a Dynamic Frequency Scaling (DFS) approach based on the control of the FIFO occupancy level. The control law has been implemented in hardware (full-custom) and the closed-loop system stability has been studied. Simulation results show the effectiveness of the proposed DVS strategy that should be extended to the whole H.264 encoder platform
