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
MEDIUM ADVANTAGES DISADVANTAGESWeb (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 mediaQuick timeWindows 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
MEDIUM ADVANTAGES DISADVANTAGESInteractive CD-ROM - Good for large media files -Require physical
distributionDVD - Good for large media files Requires physical
distributionMP3 - Web based distribution - Requires significant
processor powerVHS 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
Usage of multimedia
• Creative industries• Commercial• Entertainment and fine arts• Education • Journalism• Engineering• Industry• Mathematical and scientific research• Medicine• Document imaging• Disabilities
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
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
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.
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.
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
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.
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.
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.
Framework
• Storyboarding was chosen as a focus to illustrate how an integrated approach to the design process can help design teams.
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.
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.
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
Types of navigation
• A) Simple Text-Based Navigation• B) JavaScript based navigation• C) Image Based Navigation• D) Sliding/DHTML Menus
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.
• 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.
• 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.
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.
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
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.
