摘要

事实表明,现代信息通信系统的发展与无线技术的广泛应用趋势相一致。其运行协议的智能化水平也在不断提高。因此,用于数据传输的无线信息通信技术的特性也在不断增加。这有助于在为关键基础设施的运行提供信息支持的过程中,将其用于远程机器人平台的数据传输。事实证明,在现有机载电信技术的基础上以所需的比特强度传输视频数据时,会出现明显的时间延迟。因此,信息传输的效率水平受到影响。另一方面,视频信息的可靠性也会受到影响。有人认为,解决问题的办法在于进一步开发视频信息流的编码技术。最常见的平台是 JPEG 格式。不过,这种格式也有缺点。它们指的是在检测心理视觉成瘾潜力降低的情况下压缩水平的损失。这篇文章证实了一种改进方法,即在光谱参数空间中使用经调整的编码技术。这种方法包括检测频谱阵列中的子带,然后将其参数化,形成具有重要水平和长度的结构成分。建议在考虑到片段信息量和减少结构冗余量的情况下进行进一步处理。通过检测光谱子带,证实了一种构建压缩光谱阵列技术的方法。我们创建了一个模型,用于查找光谱参数空间中转换片段的信息量。该模型考虑到了可用的冗余量,而冗余量是通过确定结构成分值的约束条件来确定的。目前已开发出一种在光谱参数描述中对片段进行编码的方法。该方法的主要基本组成部分与处理双分量结构参数分量集有关,同时考虑到其内容的特殊性取决于量化过程的存在。

METHOD OF ENCODING VIDEO DATA IN SPECTRAL-PARAMETRIC SPACE
It is shown that the development of modern infocommunication systems is followed by the trend of widespread use of wireless technologies. The level of intellectualization of the protocols of their functioning is increasing. Accordingly, the characteristics of wireless infocommunication technologies for data transmission are increasing. This contributes to their use for data transmission from remote robotic platforms in the process of information support for the functioning of critical infrastructure. It is substantiated that the transmission of video data with the required level of bit intensity on the basis of existing on-board telecommunication technologies is organized under conditions of significant time delays. Consequently, the level of efficiency of information delivery is lost. On the other hand, there are losses in the reliability of video information. It is argued that the option for solving the problem lies in the further development of technologies for encoding video information streams. The most common platform is the JPEG format. However, the city has disadvantages. They refer to the loss of compression levels in the event of a reduction in the potential for detecting psychovisual addictions. The article substantiates an approach for improvement, which consists in the use of an adapted coding technology in the spectral-parametric space. This approach consists in detecting subbands in spectral arrays and their subsequent parameterization with the formation of structural components at a significant level and length. Further processing is proposed to be carried out taking into account the informativeness of segments and reducing the amount of structural redundancy. An approach for constructing a technology for compression of spectral arrays with the detection of spectral sub-bands is substantiated. A model has been created to find the amount of information for transformed segments in the spectral-parametric space. This takes into account the available amount of redundancy, which is established by determining the constraints on the values of structural components. A method for encoding segments in spectral-parametric description has been developed. The main basic components of the method relate to the processing of sets of two-component structural-parametric components, taking into account the peculiarities of their content depending on the presence of quantization processes.
