1 CHAPTER 4

2 Advantages of multimedia Changing that nature of reading Ability to link to another document Deliver information through multiple mediums Provide the search facilities Attractive by using multiple mediums

3 MEDIUMADVANTAGESDISADVANTAGES Web (HTML)- Widespread ease of access - Seldom optimized for printing Print document format(PDF) - Retains precise formatting -takes a little time to open Acrobat Player Web Browser w/Multimedia plug-ins - Wide variety of media- Bandwidth limitations Real media Quick time Windows media - Large files start to play (stream) before entire file downloaded - Need streaming server to host Handwritten lecture notes with document camera - Quick and easy for instructor - Writing may be illegible Flash-optimized for web- Requires periodic updates of flash plug-ins Authorware Director - Very sophisticated interactive multimedia capabilities - Requires browser plug-in

4 MEDIUMADVANTAGESDISADVANTAGES Interactive CD-ROM- Good for large media files-Require physical distribution DVD- Good for large media filesRequires physical distribution MP3- Web based distribution- Requires significant processor power VHS videotape-Better quality than most video streams - Linier format Photos, 35mm slides-can be converted to video format - Web delivery of high resolution images is slow on modem connection Powerpoint- Can be good for teleclassroom presentation - Awkward or not optimized for web delivery Word processing software (word)- Quick and easy for instructor - Requires optimization (font style size, etc.) for video display. Excel- Quick and easy for instructor - Requires optimization( font style,size, etc) for video display Photos, books, or printed materials- Quick and easy for instructor Requires document camera, or scanning/ digitizing

5 Usage of multimedia Creative industries Commercial Entertainment and fine arts Education Journalism Engineering Industry Mathematical and scientific research Medicine Document imaging Disabilities

6 Character of multimedia Multimedia systems must be computer controlled The information they handle must be represented digitally The interface to the final presentation of media is usually interactive

7 Introduction to storyboard A storyboard is an expression of everything that will be contained in the program. What menu screen will look like, what pictures( still and moving) will be seen when and for how long, what audio and text will accompany the images. Typically, storyboards may be written documents and off- the-shelf storyboard pads for tv and video formats, adaptable for multimedia, are available

8 Function of storyboard Assist in meeting the needs of users with a user- friendly manner. Pushing in solving a problem more creatively through a lower cost. Encourage the team to act as a filter reviews and makes decisions in the prevention of the features that are not essential to the story generated Ensure that the implemented features are easy, simple and intuitive.

9 Categories of storyboard The thumbnail storyboard Floating storyboard Frame storyboard

10 Procedures in creating storyboard A) decide what to include - understand users, their background, and goals - understand the system and its features - preferably using a large whiteboard - identify people and artifacts in the storyboard - develop the storyboard scenario.

11 B) Build the storyboard. – Break the story into smaller sections called frames or panes. Describe each frame in a short sentences. – Draw a picture matching to each of these sentences. – Draw the user, the product and other important objects in each frame – Include people with illustrating interaction. – Indicate the passage of time only when it is relevant

12 Advantages of storyboard Cost effective, accurate planning. Easy to identify problems early before it happens. If the storyboard looks wrong, the project will too. Storyboard can be a way to rehearse themselves before producing original work. The freedom to experiment without causing the producer to stroke-out. Omission and lost links can be spotted in the storyboard. A storyboard acts as a reference and enables you to see potential problems.

13 Disadvantages of storyboards Interaction between the storyboard and a user is limited Project team members may be reluctant to hand-draw if they feel that they are bad at it.

14 Recommendations Only draw a small picture in the area Copy up or download set of storyboard sheets. Sketch in pencil Taking down short notes. Number your shots.

15 Framework Storyboarding was chosen as a focus to illustrate how an integrated approach to the design process can help design teams.

16 Objectives To enable the developer meet requirements. They can choose what kind of features of framework without having to choose its way of doing everything. supply portions that can be used independently, but it also provides the glue to carry them all together To implement the general skills in a variety of devices, types of applications, and programming tasks. To integrate with other applications more quickly. It makes more convenient to work with complex technologies.

17 Software framework FUNCTION: Inversion of control- in a framework, except for the library or normal user applications, the overall program’s flow of control is not dictated by the caller, but by the framework. Default behavior- a framework has a default behavior, default behavior should really have some valuable behavior. Extensibility- a framework can be updated by the user, normally with a selective overriding or specific by user code providing a particular functionality. Non- modifiable framework code- the framework code, in general is not allowed to be modified. User can be extend the framework, but not modify its code.

18 Develop navigation structure OBJECTIVES - visitors will stay longer and view more pages on your site if it is easy to navigate - graphic buttons that appears in small size look better than text links and help to improve your pages - to inform user where they are - to enable users to go elsewhere

19 Types of navigation A) Simple Text-Based Navigation B) JavaScript based navigation C) Image Based Navigation D) Sliding/DHTML Menus

20 Navigation maps Recommendations a)How to please your human visitors: - Put your menu system or navigation links at the top or on the left. Its shows when most users are top- to- bottom and left-to-right readers. - Build your menu or navigation links so that a user knows where to click and what page it will take them to. - Don’t blur your links. This depends on the color of the text and font size used. - Create mouse over on your graphic links. This makes it incredibly easy for a user to understand that the link exists and what it does.

21 b) How to please the search engine Search engine bots better at reading Flash files, but the ability is still in its infancy. Because of that don’t put your main navigation system in Flash. Some search engines cant follow JavaScript links, don’t use those types of links unless you absolutely have to. With graphical links, make sure you have a value in image’s ALT attribute. Since there virtually no text-only browser still in use. This is important to tell the search engine what sort of content you have at the linked to page.

22 How to please both humans and bots. – Construct an intuitive linking structure that allows for any pages to be reached from any other in 2-3 clicks. – Don’t put pages are your site that only have one link into them from the rest of your website. – Provide more than one way to navigate the website. A great way is to is put major links in a section at the bottom of the page.

23 STORING MULTIMEDIA The applications and operating system directly manage both the multimedia and associated data models. The multimedia is store in one or more files on the local system drive, for instance CD-ROM A storage device may hold information, process information, or both.

24 TYPES OF STORAGE DEVICES Volatile Chip Non-volatile chip (optical discs) – Optical discs – A floppy disk – A USB Flash Drive – Others (Magnetic tape) – Magnetic disk

25 ADVANTAGES can keep music, photos, important text files all at one comfortable place. Multimedia drivers are present in some configuration or in other words, several storage capabilities, from 500 GB to 2 TB or even more. The biggest advantages about having a standalone multimedia drive is about zero worries about losing data if your system drive need to be formatted because of operating system problem.
