Answer:
Adequate time and efficient planning is required for multimedia production, which assures that the project will be proceed smoothly and certainly ensures that the information reaches the target audience. Following are the phases for development of complex multimedia projects. Multimedia and Desktop Publishing.

Conceptual Analysis and Planning:
The process of multimedia making begins with a conceptual ignition point. Conceptual analysis identifies a appropriate theme, budget and content availability on that selected theme. Additional criteria like copyright issues also are considered in this phase.

Project design:
Once the theme is finalized objectives, goals, and activities are drawn for the multimedia project. General statements are termed as goals. The specific statements in the project is known as the objectives. Activities are series of actions performed to implement an objective. These activities contribute to the Project design phase.

Pre-production:
Based on the planning and design, it is necessary to develop the project.
The following are the steps involved in pre-production:

Budgeting:
Budgeting for each phases like consultants, hardware, software, travel, communication and publishing is estimated for all the multimedia projects.

Multimedia Production Team:
The production team for a high-end multimedia project requires a team efforts. The team comprises of members playing various roles and responsibilities like Script writer, Production manager, Editor, Graphics Architect, Multimedia Architect and Web Master.

Hardware/Software Selection:
All multimedia Application requires appropriate tools to develop and playback the application. Hardware includes the selection of fastest CPU, RAM and huge monitors, sufficient disc for storing the records. Selection of the suitable software and file formats depends on the funds available for the project being developed.

Defining the Content:
Content is the “stuff’ provided by content specialist to the multimedia architect with which the application is developed, who prepares the narration, bullets, charts and tables etc.

Preparing the structure:
A detailed structure must have information about all the steps ‘along with the time line of the future action. This structure defines the activities, responsible person for each activity and the start/end time for each activity.

Production:
In the multimedia application, after the pre-production activities, the production phase starts. This phase includes the activities like background music selection, sound recording and so on. Text is incorporated using OCR software, Pictures shot by digital camera, Video clips are shot, edited and compressed. A pilot project is ready by this time.

Testing:
The complete testing of the pilot product is done before the mass production to ensure that everything is in place, thereby avoiding the failure after launch. If it’s an web . based product its functioning is tested with different browsers like Internet Explorer, Chrome, Mozilla and Netscape Navigator. If it is a locak multimedia application on a LAN it must be deployed in the server for testing purpose. After the testing process are over, the product is incorporated with valid suggested changes.

Documentation User documentation is a mandatory feature of all multimedia projects. The documentation has all the valuable information’s starting from the system requirement till the completion of testing. Contact details, e-mail address and phone numbers are provided for technical support and sending suggestions and comments.

Delivering the Multimedia Product:
Multimedia applications are best delivered on CD/DVD or in the website . In reality various challenges are faced while delivering through internet, like bandwidth problems, huge number of plug-ins required to play audio and video and long downloading time. Finally, a multimedia application is delivered in a more effective way by the integration of two mediums CD-ROM/DVD and Internet.

Answer:
File Formats for Multimedia:
The following is an outline of current file formats used for the production and delivery of multimedia data.
Text Formats:
RTF Rich Text Format:
is the primary file format introduced in 1987 by Microsoft with the specification of their published products and for cross-platform documents interchange.

Plain text:
Plain text files can be opened, read, and edited with most text editors. Commonly used are Notepad (Windows), Gedit or nano (Unix, Linux), TextEdit (Mac OS X) and so on. Other computer programs are also capable of reading and importing plain text. Plain text is the original and popular way of conveying an e-mail.

Image Formats:
TIFF (Tagged Image File Format):
This format is common in desktop publishing world (high quality output), and is supported by almost all software packages. Recent versions of TIFF allows image compression, and the format is comfortable for moving large files between computers.

BMP (Bitmap):
Initially this format is in use with Windows 3.1. It is quite large and uncompressed and hence BMP is used for the high-resolution or large images.

DIB (Device Independent Bitmap):
This format which is similar to BMP, allows the files to be displayed on a variety of devices.

GIF (Graphics Interchange Format):
GIF is a compressed image format. Most of the computer color images and backgrounds are GIF files. This file format is best suitable for graphics that uses only limited colors, and it is the most popular format used for online color photos. 13-bit Color look up table is used by the GIF format to identify its color values. This format is supported widely.

JPEG (Joint Photographic Experts Group):
JPEG was designed to attain maximum image compression. It uses loss compression technique, where a compression method is referred that loses some of the data required for the image reconstruction. It works good with photographs, naturalistic artwork, and similar material but functions less on lettering, live drawings or simple cartoons.

TGA (Tagra):
It is the first popular format for high-resolution images. TGA is supported by Most of the video-capture boards.

PNG (Portable Network Graphics):
An extensible file format for the less loss, portable and well compressed storage of raster images. PNG acts as replacement for GIF and also replaces multiple common uses of TIFF. PNG works good with online viewing applications like worldwide web. So it is fully streameable with a best display option.

Digital Audio File Formats:
1. WAV (Waveform Audio File Format):
It is the most popular audio file format in windows for storing uncompressed sound files. In order to attain the. reduced file size it can also be converted to other file formats like MP3.

2. MP3 (MPEG Layer-3 Format)
3. MPEG Layer-3 format is the most popular format for storing and downloading music. The MP3 files are roughly compressed to one-tenth the size of an equivalent WAV file.

4. OGG:
A free, open source container format that is designed for obtaining better streaming and evolving at high end quality digital multimedia. It can be compared to MP3 files in terms of quality.

5. AIFF (Audio Interchange File Format):
A standard audio file format used by Apple which is like a WAV file for the Mac.

6. WMA (Windows Media Audio):
It is a popular windows media audio format owned by Microsoft and designed with Digital Right Management (DRM) abilities for copyright protection.

7. RA (Real Audio Format):
Real Audio format is designed for streaming audio over the Internet. The digital audio resources are usually stored as a computer file in computer’s hard drive or CD/DVD. Besides the variety of audio file formats available, the most common formats are wave files (.WAV) and MPEG Layer-3 files (.MP3), WMA and RA.

Digital Video File Formats:
AVI (Audio/Video Interleave):
AVI is the video file format for Windows. Here sound and picture elements are stored in alternate interleaved chunks in the file.

MPEG (Moving Picture Experts Group):
MPEG is a standard for generating digital video and audio compression under the International Standards Organization (ISO) by the group of people. The group has developed MPEG-1, the standard on which Video CD and MP3 are based, MPEG-2, the standard that supports products as Digital Television set top boxes and DVD, MPEG-4, the standard for multimedia and mobile web. MPEG-7, the standard for search of audio and visual content. Research on MPEG-21 “Multimedia Framework” has started in 2000. Simply MPEG is the standards for digital video and audio compression.
