This document discusses multimedia and characterizes different types of media. It defines multimedia as any system that supports more than one type of media, such as text, graphics, speech, and music. Continuous media like audio and video are described as having a time component, whereas discrete media like text and images do not. The document also outlines properties of multimedia systems, including the combination of different media types, the independence of each media, computer-supported integration, and use as a communication system. Characteristics of continuous data streams, such as inter-packet intervals and packet size variation, are also covered.

Multimedia data and information must be stored in a disk file using formats similar to image file formats. Multimedia formats, however, are much more complex than most other file formats because of the wide variety of data they must store. Such data includes text, image data, audio and video data, computer animations, and other forms of binary data, such as Musical Instrument Digital Interface (MIDI), control information, and graphical fonts. (See the "MIDI Standard" section later in this chapter.) Typical multimedia formats do not define new methods for storing these types of data. Instead, they offer the ability to store data in one or more existing data formats that are already in general use.
For example, a multimedia format may allow text to be stored as PostScript or Rich Text Format (RTF) data rather than in conventional ASCII plain-text format. Still-image bitmap data may be stored as BMP or TIFF files rather than as raw bitmaps. Similarly, audio, video, and animation data can be stored using industry-recognized formats specified as being supported by that multimedia file format.

Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

Online aptitude test management system project report.pdfKamal Acharya
The purpose of on-line aptitude test system is to take online test in an efficient manner and no time wasting for checking the paper. The main objective of on-line aptitude test system is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. For students they give papers according to their convenience and time and there is no need of using extra thing like paper, pen etc. This can be used in educational institutions as well as in corporate world. Can be used anywhere any time as it is a web based application (user Location doesn’t matter). No restriction that examiner has to be present when the candidate takes the test.
Every time when lecturers/professors need to conduct examinations they have to sit down think about the questions and then create a whole new set of questions for each and every exam. In some cases the professor may want to give an open book online exam that is the student can take the exam any time anywhere, but the student might have to answer the questions in a limited time period. The professor may want to change the sequence of questions for every student. The problem that a student has is whenever a date for the exam is declared the student has to take it and there is no way he can take it at some other time. This project will create an interface for the examiner to create and store questions in a repository. It will also create an interface for the student to take examinations at his convenience and the questions and/or exams may be timed. Thereby creating an application which can be used by examiners and examinee’s simultaneously.
Examination System is very useful for Teachers/Professors. As in the teaching profession, you are responsible for writing question papers. In the conventional method, you write the question paper on paper, keep question papers separate from answers and all this information you have to keep in a locker to avoid unauthorized access. Using the Examination System you can create a question paper and everything will be written to a single exam file in encrypted format. You can set the General and Administrator password to avoid unauthorized access to your question paper. Every time you start the examination, the program shuffles all the questions and selects them randomly from the database, which reduces the chances of memorizing the questions.

6. The Perception Medium
• Perception media help humans to sense their
environment.
• The perception of information occurs mostly
through seeing or hearing the Information
• For the perception of information through seeing,
the visual media such as text, image and video are
used.
• For the perception of information through hearing,
auditory media such as music, noise and, speech
are relevant.

7. The Representation Medium
• Representation media are characterized by internal
computer representations of information. That is, how is
the computer information coded
• The various formats used to represent media information
in computer.
• For example:
A text character is coded in ASCII or EBCDIC code.
An audio stream can be represented using a simple
PCM (Pulse Coding Method) with a linear quantization
of 16 bits per sample.
An image can be in JPEG format. 7
8. • Storage media refer to a data carrier which
enables storage of information.
• However, the storage of data is not limited only to
the available components on a computer.
Therefore, paper is also a storage medium.
• Microfilm, floppy disk, hard disk, and CD-ROM are
examples of storage media.
The Storage Medium

10. • The information exchange medium includes all
information carriers for transmission, That is all
storage and transmission media.
• The storage medium is transported outside of
computer networks to the destination, through
direct transmission using computer networks,
or through combined usage of storage and
transmission media.

14. Independence
o An important aspect of different media is
their level of independence from each
other
o Multimedia require several levels of
independence
o A computer controlled video recorder
stores audio and video information, but
there is an inherently tight connection
between the two types of media. Both
media are coupled together through the
common storage medium.

15. 15
Computer-supported Integration
o Computer-controlled data of independent media
can be integrated to accomplish certain functions.
For such a purpose, timing, spatial and semantic
synchronization relations will be included.
o For example, in conventional systems, a text
message can be sent to other users but, a
multimedia system with a high level of integration
allows this function also for audio messages or
even for a combination of audio and text.
16. 16
o Multimedia information cannot only
be created, processed, presented and
stored, but also distributed above the
single computers boundary.
o Distributed environments enable
particularly interesting multimedia
applications.
Communication System
17. 17
DEFINITION :
Uninterrupted flow of a long sequence of data, such as in audio and video data files.
CHARACTERISTICS :
Static, time-independent discrete media: Text, graphics, images. Information in
these media consist exclusively of a sequence of individual elements without a
time component.
Dynamic, time-dependent continuous media: Sound, video. Information is
expressed as not only of its individual value, but also by the time of its occurrence.
DATA STREAMS
18. 18
Asynchronous Transmission Mode
The asynchronous transmission mode provides for communication with no
timely restrictions. Packets reach the receiver as fast as possible. Protocols of
the worldwide Internet for electronic mail transmission are an example.
Synchronous Transmission Mode
The synchronous transmission mode defines a maximum end-to-end delay for
each Packet of a data stream. A packet can reach the receiver at any arbitrary
earlier time.
Isochronous Transmission Mode
The isochronous transmission mode- defines, besides a maximum end-to-end
delay for each packet of a data stream, a minimum end-to-end delay. This
means that the delay of individual packets is bounded
