Today, special devices have means of storing video images in digital form on a computer’s magnetic media as computer graphics. 10. By rapidly delivering these digital graphics images to the computer screen one after the other we can simulate the kind of video images we see on our television set. 11. Today software companies are busy creating programmes to manage multimedia resources. 12. We insisted on their developing the programs which vary considerably in design, but are all capable of incorporating text, graphics, sound and video into one program. 13. The difficulty was providing special software for dealing with external devices such as CD-ROM drives and videodisc drives and for incorporation of digital video.
Task 9. Unscramble the letters to complete the definitions from an online dictionary.
1 dheasenpho _________: device which covers each ear and allows you to listen to audio without other people hearing;
2 pertyhtex ________: text with links to other text or other parts of a document or web page;
3 Tacvitiyniter __________: allowing two-way communication between a program and the user;

Task 10. Translate into English
1. Одним з методів скорочення об'єму, що займає музика, є MIDI (Musical Instrument Digital Interface). 2. Файли у форматі MIDI зазвичай містять інструкції типу: «зіграти на такому-то інструменті таку-то ноту протягом такої-то кількості секунд». 3. В результаті MIDI-файли займають незначний обсяг. 4. Проте сам характер представлення звуків не міг повністю задовольнити як користувачів, так і розробників. 5. Потрібно було знайти принципово нове рішення. MIDI- це скоріше не метод запису звуку, а спосіб запису команд, що посилаються музичним інструментам. 6. МIDI-файл (зазвичай це файл з розширенням MID) містить посилання на ноти, а не на запис музики як такий. 7. Коли МIDI-сумісна звукова карта отримує МIDI-файл, карта шукає необхідні звуки в таблиці через ці посилання. 8. Певний інструмент відповідає конкретному посиланню. 9. Так, наприклад, великий барабан визначений цифрою 55. 10. Коли звукова карта знаходить посилання під номером 55, вона видає звук великого барабану. 11. Зразки зберігаються на диску і завантажуються в процесі відтворення звукових сигналів. 12. Крім того, існує можливість для зміни звучання інструментів, а також заміни їх.

Text B. NEW APPLICATIONS OF THE COMPUTER
Among the most exciting new applications of the computer is the ability to bring together information that exists in a variety of forms. New computer tools, often using combinations of hardware and software, are now providing better ways to bring together information that is stored on other media in the form of graphics, sound, and video. These new programs, known collectively as multimedia applications, bring the other media sources under computer control.
CD-ROM - based Multimedia
One of the problems in dealing with computer-controlled sound and graphics is that the related files require extremely large amounts of storage. One solution is to store graphics, sound, and video files on a high-capacity device such as compact disk (CD). Compact disks can store huge amounts of data and the CD drives can be used to deliver this information to the computer's internal memory as data. Because most of these devices cannot be used to record information, they are known as read-only memory (ROM) devices. Although they are used to store computer data, these devices do not use the same kind of magnetic media generally used by computers to store data. Instead, these devices store information by permanently etching the encoded data into the same kind of plastic disk used to store and play back popular music. Because the stored data is deciphered using a laser-based reading device, there is no physical contact with the disk and no possibility of wear to the disk. Their high capacity and permanence are making CD-ROM disks a common storage and delivery tool for multimedia.
Videodisc
The videodisc player is similar to the compact disk player, but the disks used are somewhat different. While the CD disks are used to store and deliver computer data, videodiscs are used to store and deliver video images. They can be used to deliver high-quality video to a television set by displaying the video images in sequence at the same 30-frames-per-second rate that is used in broadcast television. Many videodisc players can be controlled by computer. And because the video images are stored a single image at a time, one image can be displayed under computer control or a sequence of images can be displayed to create the effect of live video.

Digital Video
Most of the video images we are used to seeing on our home television sets were originally captured using a video camera and stored on video tape. But today, special devices make it possible to store video images in digital form on a computer's magnetic media as computer graphics. By rapidly delivering these digital graphics images to the computer's screen one after the other, we can simulate the kind of video images we see on our television set.
Computer-delivered digital video presents many exciting possibilities. Because the video images are stored on normal computer media as data in separate graphics files, there is unlimited potential for editing the video sequence using computer graphics editing methods. And because the video images can be displayed on the computer's screen as graphics, they can be incorporated into presentations that in the past used only still pictures.
Multimedia Authoring Systems
In order to manage the presentation of information that is stored in dissimilar formats, new multimedia-based authoring systems are being developed. These programs vary considerably in design, but all are capable of incorporating text, graphics, sound, and video into one program. These programs provide special tools to manage these resources and to deliver them to the user interactively.
Virtual Reality
With the emergence of ever more realistic computer graphics, many people have found the computer's monitor to be a limited output device for displaying them. Many found the two-dimensional view of modern, complex colour graphics did not fully convey the potential held by this new form of computerized information. This led to the investigation of ways to present and to interact with more realistic, three-dimensional displays. The result was the development of highly realistic displays that provide users with the feeling that they are fully immersed in the computer image. Collectively, these applications have become known by the title of "virtual reality."
