Mobile devices are typically resource constrained, with small screen size and limited computing power, and they are battery-powered. Multimedia applications, on the other hand, are typically resource-intensive and have strict quality-of-service requirements. Such disparity in requirements makes deploying multimedia applications for mobile devices over wireless networks a considerable challenge

2. INTRODUCTION:
❖ Exchange of information among people at locations physically
separated has always been the focal point of communication studies.
❖ Telegrams and snail-mail were replaced by telephones.
❖ Mobile technology opened the floodgates to human imagination.
❖ This technology has touched every strata of society and especially
privileged a common mass of society.
❖ A mobile application is a software application that is designed to run
on a mobile device such as smartphone and tablet.

3. HISTORY OF SMARTPHONES:
❖ The first wireline telephone system was introduced in the year 1877.
❖ Mobile telephone was introduced much later in the year 1946.
❖ Modern mobile phones also support a wide variety of other services such
as text messaging, MMS, email, internet access, gaming and photography.
❖ In 1973, John F. Mitchell and Martin Cooper of Motorola demonstrated the
first handheld mobile which weighed a whopping 2 kg.
❖ Between 1983 and 2014, the mobile phone subscriptions grew to over 7
billion. As of today, Samsung, Apple and Huawei are the top mobile phone
manufacturers. 3

4. SMARTPHONES IN MULTIMEDIA APPLICATION:
❖ Mobile devices are typically resource constrained, with small screen size
and limited computing power, and they are battery-powered.
❖ Furthermore, these devices depend mainly on wireless technologies,
which have restricted range/bandwidth and fluctuating channel conditions
for transmissions of data.
❖ Multimedia applications, on the other hand, are typically resource-
intensive and have strict quality-of-service requirements.
❖ Such disparity in requirements makes deploying multimedia applications
for mobile devices over wireless networks a considerable challenge.

5. ADVANCES IN SMARTPHONES:
❖ The advances in hardware has allowed several features to be developed in
mobile devices, which were once considered impossible.
❖ Features like touch-screen, accelerometer, GPS navigation, music and video
playback, vibration, ability to watch streaming video, play games, infra-red,
Bluetooth, WiFi connectivity, NFC, messaging, internet browsing and email
and also working as a wireless modem.
❖ Every other day, a new mobile device comes out with a new feature never
seen before. All these features have made a mobile device a smart mobile
device.

6. DESIGNING AN APPLICATION:
❖ There are various software development methods defined and designed which
are used/employed during development process of software, these approaches
are also referred as “Software Development Process Models”.
❖ After this stage, planning and defining the requirements is carried out.
❖ Next comes the stage where designing is carried out.
❖ Once the application is coded, it is time for testing.
❖ After the application has been tested thoroughly, it gets ready to be released
in the market.

7. TYPES OF APPLICATION:
There are 3 types of mobile applications that are available.
They are:
1. Native
2. Web
3. Hybrid
7

8. NATIVE:
❖ These apps live on the device. They are opened on the device through the
home screen icons.
❖ Native apps are available on the application store (such as Google Play or
Apple’s App Store) and can be installed.
❖ As because the apps are specifically developed for one platform, they can
take full advantage of all the device features — they can use the camera, the
accelerometer, the GPS, the compass, the contacts list, and so on.
❖ Gestures could also be included (either standard operating-system gestures
or new, app-defined gestures). 8

9. WEB:
❖ Web mobile applications are software programs that execute directly
from the web browser on mobile phones and tablets.
❖ These web-based mobile apps are not installed on the handheld mobile
device but are run on web-hosted servers.
❖ These web-based mobile applications can be made on a single platform
as they are not restricted by the operating systems of the device.
9

10. HYBRID:
❖ These apps are a mixture of part native and part web apps.
❖ Like native apps, they are available in an app store and can take
benefit of the many device features available.
10

11. TYPES OF MOBILE OS:
❖ A mobile operating system or mobile OS is a system software for mobile
devices like smartphones, PDAs, tablets and other mobile devices.
❖ This software is different from the one that is installed on a desktop or a
laptop, because it has specific “mobile” features.
❖ Some of the more popular and prevalent OS are:
A. Android
B. iOS
C. Windows OS
11

12. ANDROID:
❖ One of the most popular OS on mobile devices is the android OS of
Google.
❖ It was first released as ‘Astro’ on 20th September 2008.
❖ Next upgrades, ‘Bender’ and ‘Cupcake’ were also released.
❖ Google then adopted the process of naming Android versions after any
dessert or a sweet in alphabetical order.
❖ The other releases were Donut, Éclair, Froyo, Gingerbread, Honeycomb,
Ice Cream Sandwich, Jelly Bean and Marshmallow, Nougat.
❖ The Latest version of Android is Android 11.0
12

13. iOS:
❖ This operating system is a product of Apple.
❖ Mobile devices like iPhone, iPad and iPod touch are powered by this OS.
❖ It was placed second only to Android as far as sales are concerned.
❖ The latest version of iOS and iPadOS is 14.2.
❖ The latest version of macOS is 11.0.1.
13

14. WINDOWS OS:
❖ Microsoft plunged into the mobile devices market by coming up with
their own OS known as Windows.
❖ Although most people using computers know the usage of Windows
OS, the OS on mobile devices was not an overnight hit.
❖ Windows 10 is the latest OS for mobile devices.
14

15. CONCLUSION:
❖ The future for mobile multimedia applications looks bright.
❖ From a hardware viewpoint, it is clear that the amount of memory needed
for storing and processing multimedia content will only make the mobile
phones becoming rich, multimedia-centric devices.
❖ Advancements in display and camera technologies along with algorithmic
and coding trends will pave the way for more and richer multimedia
functionality.
