This paper presents a new error concealment algorithm, which is suitable for the H.264/AVC coding standard and the hardware implementation. This algorithm can be dividing into two major categories. In the spatial domain, we use the reliable neighboring pixel values with edge detection method to conceal all the lost pixels in the block. In the temporal domain, we propose a variable block size error...
In this work, we present a hardware architecture prototype for the various types of transforms and the accompanying quantization, supported in H.264 baseline profile video encoding standard. The proposed architecture achieves high performance and can satisfy quad full high definition (QFHD) (3840middot2160@150Hz) coding. The transforms are implemented using only add and shift operations, which reduces...
In this paper, we present an efficient H.264 / AVC intra 16times16 frame coder system. The system achieves real-time performance for video conference applications. The INTRA 16times16 is composed by intra 16times16 prediction, integer transform, quantization AC, inverse quantization AC, quantization DC, hadamard, inverse quantization DC, and inverse integer transform. The proposed hardware is implemented...
