Email: [email protected] ABSTRACT The progress of digital media technology is a milestone event in the history of information storage and transmission. Compared with the access of information storage and transmission in the past, the digital media take the digital data as medium. It is worth paying attention to and do researches about the difference of digital media and traditional media, how to fulfil it, the value and characteristic of it. It is the characteristic of digital media that binary data is used as the medium of information storage and transmission, and network transmission is used to store and forward information to realize information interaction. Through the compiler, we can convert different forms of information including text, pictures, audio and so on into binary data, or reverse these digital types of data back to the original forms, so as to realize the conversion of traditional information and digital media information. Digital media technology has made great progress since its emergence. From the initial period of using telegraph to transmit information and only sending point- and-line data to the current way of massive data transmission through the network, digital media cutting-edge technologies: VR and AR have matured to be put into the use of civil equipment; VR glasses and other devices allow users to run corresponding functions to provide virtual reality services, and AR technology has been widely used in areas such as navigation enhancement and office interaction enhancement. By searching the literature, observing the changes of data in registers and solid-state drives, using the corresponding functions to realize the input and output of data, sending and receiving methods, analyzing the definition, implementation and development of digital media technology. Keywords: Digital media, Digitization, Information storage, Information transmission. 1. INTRODUCTION time, the development of network technology also means that large-scale, high-speed data transmission has The emergence of digital media can be traced back to become a reality. With the development of computer and telegraph communication. This period of digital media network technology to support the progress of digital mainly rely on radio technology to achieve. The media, the advantages of high density, fast transmission technique emerged in the 1830s and was mainly studied and compatibility of various forms of digital media have in the United States and Britain. Because of the order of been realized. Digital media technology is also fully magnitude of transmission, telegraphy could only reflected in the development of human life. In this transmit text data, which had to be manually decoded situation, we should understand how digital media is after transmission. Although this mode of transmission is realized, how it is used in our life, what kind of very advanced compared to the traditional mail in that significance it has for us and how it will develop in the time, the transmission volume is still small and the future. transmission type is relatively simple. With the development of Internet technology and computer 2. DEFINITION OF DIGITAL MEDIA technology, the progress of digital media technology also ushered in a take-off. Advances in computer technology 2.1. The media have made it possible to convert more types of data. Through the compiler, in addition to text, images, audio Media refers to the medium through which also has the possibility to store and forward. At the same information is transmitted. There are many ways to transmit information, but no matter what way, they all Copyright © 2022 The Authors. Published by Atlantis Press International B.V.

You simply bind this in it, is the media. meta property to binary data. For natural information such as sound and image, we only need to analyze its Traditional media generally refers to newspapers, physical characteristics, and then transform the articles and other paper items recorded in the form of corresponding physical characteristics. However, for the words. With the development of science and technology, artificial information type like text, we need to explore by broadcasting, Internet and other communication methods ourselves, summarize the formation methods, and then have emerged. identify the attributes corresponding to binary data. 2.2. Digital Media 3.2. Realization types of digital media The emergence of digital media means a At present, the main types of digital media are text, revolutionary progress in the way of human information image and audio. On the basis of these three types, new transmission and storage. Different from traditional forms can be formed by combining with each other. For information, digital media makes all kinds of information example, video can be formed by playing images in into binary data, which greatly increases the density of sequence and adding audio. data and makes the quantization of information easy to realize. And make the information copy, transmission efficiency greatly improved. 3.2.1. Digitization of characters The development of digital media in storage, Text is an important way for human to convey including data, text, images, audio and other ways to information, and this ancient tool cannot be ignored in convert and save, enrich the diversity of information; At digital media. Compared with other types of information, the same time, in the transmission of information, all text itself has diversity, and different languages need connected network, satellite signal equipment, can corresponding conversion methods. If English is used as achieve data communication, communication channel an example, you only need to allocate the corresponding interaction. In the case of further development, it can also binary digits for all letters, and then allocate the realize accurate query and download data, personalized corresponding binary digits for blank lines and symbols. data sharing becomes a reality, and intelligent data The alphabet language itself saves a step for digital transmission. conversion, and the number of letters plus symbols is small and easy to implement; If you take Chinese as an 3. REALIZATION OF DIGITAL MEDIA example, you have a large number of characters, but you also need to allocate binary data for each character. In 3.1. Implementation method of digital media short, every language should have meta-attribute properties: English letters, Chinese characters, for The emergence of digital media in addition to example, just by converting these hard-to-subdivide development is also a challenge, how to successfully meta-attribute types into their binary counterparts. A digitize information is the key method. The binary method similar to a telegraph. approach requires a methodology mature enough to input For the existence of a variety of different characters, and output various types of information in binary form. should be changed to allocate corresponding In order to achieve this purpose, compilation has higher transformation mode; However, from the aspect of requirements. hardware, it is impossible to design input and output In order to display these binary data on all devices, a devices for each language. For example, it is impossible unified compilation, modulation and demodulation to design their own keyboards for input devices such as method is needed. If the user uses different data keyboards for each language. For Chinese, a language processing procedures, it may lead to data distortion, or with a large number of basic characters, it is also even garbled code, which violates the basic principles of unrealistic to set direct corresponding keys for each meta- information transmission, and the advantages of digital character. In the development of computers, English was media can not be reflected. This is also the disadvantage the earliest and most widely used environment, so the of digital media: compared with traditional media, binary initial development of digital media was naturally based data cannot be read directly by human beings, which is on English. Under this premise, we can design the second weaker in terms of ease. Without proper conversion, the transformation on the basis of the first transformation, binary information is useless numbers. that is, on the basis of the designed English letters, and then use English to continue to transform into other We only need to dig out the meta attributes of each languages. For example, in Chinese, tools such as pinyin type of data and allocate binary data corresponding to the and Wubi are designed to realize this idea. In this way, corresponding attributes. For the definition of meta- attribute, we should require it to be able to fully express 139  Advances in Economics, Business and Management Research, volume 214 the versatility of input equipment is greatly enhanced, files require larger sounding parts and more elaborate and users can easily switch between different characters. frequency modulators. The finer the data, the larger the data amount. Even if we adopt the optimization method 3.2.2. Digitization of images to reduce the data amount, the basic data principle cannot be changed. Therefore, a larger amount of data depends Compared with the traditional image preservation on a higher transmission speed. The development of using optical properties, digital image preservation digital media needs to be synchronized, and the progress conditions are more relaxed, and dissemination is more of a single development needs the cooperation of other convenient. How to binary and save the image is the attributes before it can be put into practical use. primary problem. Digital preservation means that we need to translate the optical properties of the image itself 4.3. Combination of digital media information into digital properties. The main properties of images are color, brightness and gray scale. We cut an image into Video is the most intuitive example of digital media multiple different regions and record the color of each information integration. The form of video is formed by region. On this basis, we only need to record the continuously playing the image by frame, plus the coordinate information and the color information of the superposition of audio on the audio track. The current coordinate, and then allocate data for each color combination of digital media still has various possibilities and coordinate to achieve the preservation of image data to explore and explore.. 4.4. Development trend of digital media 3.2.3. Digitization of audio AR and VR are two main development trends of Sound is essentially a kind of wave. To understand the digital media technology. nature of this kind of sound, we only need to digitize the VR technology makes people feel immersive through wave data. The preservation characteristics of audio are images and 3D technology. Through digital media mainly loudness, tone and timbre, which are reflected as technology, VR technology is committed to giving users frequency, wavelength, wave speed and extreme value in a feeling of being fully placed in another real world. the form of wave. Therefore, we can assign numeric types to each of these attributes in turn. AR technology implants enhanced information into the real world we are in in the form of digital media to 4. DEVELOPMENT OF DIGITAL MEDIA enhance our perception and provide information. Demand is the driving force of development. For the 4.5. Development direction of digital media transmission and dissemination of information, what we desire is faster transmission speed and higher data Information transmission is ultimately determined by accuracy and accuracy, which requires both the human perception. At present, the digital media development of hardware and the improvement and technology for vision and hearing has a good optimization of software. development, but the information transfer technology for touch and even smell is still in its infancy. How to 4.1. Software Optimization comprehensively enhance the transmission of all perceptual information is still the direction of research for The main realization process of digital media is the digital media. digitization of information input and the visualization of data output. Software optimization is to optimize the 5. CONCLUSION tasks in this process. Each data should be saved in a more excellent way. How to save data in a minimum without All technologies are created and developed based on losing data? For example, most images have similar color requirements; The emergence of digital media is because in large areas. Instead, it is a method to save data in the people have higher requirements and expectations for the form of blocks for data modification to improve accuracy communication and storage of information. Digital media. At the same time, software optimizations include allows the emergence of new forms of information data, ways to read transformed data faster. so that data transmission speed and data density are greatly improved. The realization principle of digital 4.2. Hardware Optimization media is to digitize data, and rely on computer technology to realize the transformation process. The digitized data Digital media is a large amount of binary data, but in can be saved through hard disks and other hardware, and the process of input and output data, are reflected in the high-speed transmission and accurate transmission can be way of human perception. Image input and output require realized through network technology. There are infinite higher pixel density displays and generators, while audio possibilities in the development of digital media. Virtual 140  Advances in Economics, Business and Management Research, volume 214 reality and augmented reality technologies are application technology as an example, Industrial & developing steadily, but there are more possibilities Science Tribune，2021（20）, 122-123. worth exploring by digital media: the transmission of taste information and smell information, the development of digital media for human-computer interaction; Even digital media should not be limited to the preservation and transmission of information, we deliberately pursue creation, explore new human perception, create sensory perception information that does not belong to the natural world. Digital media has much more to discover. At the same time, whether there is still the possibility of optimization of digital transformation, and how to realize the digitization of new forms of data, these are still worth further research.
