Full textNew hardware architectures developed for key blocks of the ISO/IEC 14496-10 video coding standard are discussed, proposed, implemented, and validated in this thesis. The standard is also called H.264, AVC (Advanced Video Coder) or MPEG-4 part 10, and is the state-of-the-art in video coding, presenting the highest compression ratios achievable by an internationally standardized video coder (ISO/IEC and ITU-T). The H.264 has already been revised three times: the first included new profiles for fidelity extension and professional applications. The second brought the scalability support (SVC – Scalable Video Coder). The third revision supports video sources with multiple views (MVC – Multi-view Video Coder). The present work developed high performance architectures for CABAC (Context-Adaptive Binary Arithmetic Coder), which were challenging because of the bitwise data dependencies. A through revision of the alternative architectures and a specific architectural solution for CABAC encoding are presented in this thesis. A dedicated hardware architecture for a HIGH profile Deblocking Filter is also presented, developed, validated and synthesized for two different targets: FPGA and ASIC. The validation methodology is presented and applied to three different modules of the H.264 encoder. The H.264 blocks dealt with in this thesis work complement those developed by other works in the UFRGS research group and contribute to the development of complete encoders for real-time processing of high definition digital video at 1080p.

H.264/AVC is a new codec standard for video. A traditional DSP architecture is not e±cient enough for this new standard. The pro¯ling results show that Deblocking Filter consumes up to 33% running time of H.264 decoder. In this thesis, we focus on designing new instructions to speed up Deblocking Filter. Based on a standard Star¯sh DSP, we propose novel instructions and architecture for Deblocking Filter. In experiment result, we show that 28.5% improvement in computation time is achieved on Filter Processing part of Deblocking Filter by our new instructions.

Most video coding standards use block-based discrete cosine transform (DCT)and motion-compensated prediction (MCP) to reduce both spatial redundancy andtemporal. For very low bit rate coding, coarse-quantized DCT coefficients suffer discontinuities at block boundaries, namely blocking artifact, after reverse transform. Furthermore, motion-compensated prediction propagates blocking artifacts to inner-block regions, which makes artifact detection difficult. Blocking artifacts caused by motion-compensated prediction can be solved by a loop-filter, which is integrated to the codec and filtered frames are used as reference frames. The main drawback of loop-filter is its in-flexibility, i.e., users cannot enable/disable filtering freely but restricted by the received bitstream. In this study, a hybrid deblocking filter for H.264 video is proposed. To estimate inner-block discontinuities, a motion-compensated based approach is proposed. A map of detected blocking artifacts within each video frame is stored. Combining motion vectors and blocking artifact maps of previous frames, possible locations where blocking artifacts may occur can be estimated. Cooperating with oriented blocking artifact detecting and filtering, we successfully realize loop-filter performance with a post-filter. The proposed approach can also used in other DCT/MCP based codecs.

The video compression technology is more important, because the digital multimedia is widely used in our life. Block-based video coding cooperating with block transform and block motion compensation is the most widely adopted way to reduce the data redundancy in various video coding standards such as JPEG, MPEG-1/2/4, and H.264/AVC. Not only energy is compacted and de-corrected but also redundancy information is reduced. Although block structure gains data compression, it results in blocking effect which impacts the quality of compressed video. In general, block compressed technology can usually obtain acceptable quality of video but suffer from annoying blocking artifacts when it becomes worse especially in the low bit rate or high quantization parameter video environment. H.264/AVC standards include the deblocking filters inside its coding loop, in order to reduce the block effect for the visual quality of images or videos. In this work, we propose an adaptive deblocking filter algorithm to reduce blocking effect for H.264 video coding system. If block effect can not be solved, the quality of compressed video must be bad even it sets parameters and thresholds appropriately. We not only propose a deblocking filter algorithm for reducing block effect but also present an effective search algorithm to reduce coding time. The advantages of our proposed algorithm are the lower complexity of computation and better offsetA and offsetB of possession in slice level. Experiment results show that our proposed method can improve visual quality of reconstructed video. We present an adaptive deblocking filter algorithm to reduce blocking effect and reduce coding times than the JM10.2 by about 10%.

Increasing the bandwidth or bit rate in real-time video application to obtain better images quality is usually not possible or too costly. Post-processing appears to be the most practical solution because it does not require any change to existing standards. If the blocking effects can be significantly reduced, higher compression ratios at the same image quality or better quality at the same compression performance can be achieved. In this Thesis, we proposed a deblocking algorithm based on three filtering modes in terms of the activity across block boundaries. By given proper consideration of the masking effect of the HVS (Human Visual System), an adaptive filtering decision is integrated into deblocking processing. Based on three different deblocking modes appropriate for the characteristic of local region, the perceptual quality as well as the objective quality is improved without over smoothing the image details and insufficient reducing the strong blocking effect on flat region. According to the simulation results, the proposed method shows better performance than those deblocking methods by H.26L and MPEG-4 in terms of PSNR. Noticeable perceptual improvements of image quality are achievable.
