“…eir new approach involved replacing the bit shift elements of a variant of the signed DCT transform by zeros, in order to eliminate the bit shift operations. In [13], an efficient hardware implementation was proposed for high-speed vector-radix decimation-in-frequency three-dimensional DCT with an optimum area and power consumption. In [14], a novel algorithm was proposed to determine the minimum number of low-frequency DCT coefficients required for transform and quantization block in high-efficiency video coding.…”

Urbanization is the process that people shift from rural to urban areas, which has led to large numbers of left-behind children in China. The left-behind children stay in rural regions of China while their parents work in urban areas. The left-behind children have few opportunities to participate in sports due to the lacking of concern, and it is not of high quality even though they participate in sports. Therefore, it is necessary to improve the quality of left-behind children's sports participation through wireless network monitoring. Wireless network monitoring transmits high-definition (HD) video streaming in real time to facilitate feedback timely. This paper studies the two-dimensional (2D) integer discrete cosine transform (DCT) and analyzes the reason for image distortion, then an improved DCT coefficient quantization approach is proposed for long-distance real-time transmission of HD video streaming, and a noise processing with a zero-mean noise processing is added in optimized approach to solve the image distortion problem. The experimental results show that the proposed improved approach has a good performance in reducing the blocking artifacts, and within the image reconstruction, the proposed approach improves the subjective video quality.
