Multimedia Technology introduction - I created these slides for my students to teach CMP 383 Multimedia Technology at Jazan Community College , Jazan University
This is the subject slides for the module MMS2401 - Multimedia System and Communication taught in Shepherd College of Media Technology, Affiliated with Purbanchal University.
The document discusses digital audio and its uses in multimedia. It describes sound as pressure waves and how digital audio is captured through sampling. Sampling converts analog sound waves into discrete digital values through an analog-to-digital converter. The document also discusses common audio file formats like WAV and MIDI, which transmits instructions for musical notes rather than raw audio.
This document discusses digital audio and summarizes key points:
1. Digital audio involves converting sound waves to numerical data that can be easily stored, manipulated and reproduced. It allows for two types of sounds - analog and digital.
2. Characteristics of digital audio include sampling rate, amplitude, channels. Common sampling rates are 11.025KHz, 22.5KHz and 44.1KHz. File size is calculated based on these characteristics.
3. Popular audio file formats include WAV, AIFF, MP3, AAC which allow for compression. MIDI stores musical data separately from audio and allows for editing of notes.

Hardware devices that are used to input and output data to a computer are called I/O devices. Input devices capture information from the external environment and convert it into a format that can be processed by the computer. Examples include keyboards, mice, scanners, microphones, and webcams. Output devices take the processed data from the computer and present it to the user. Common output devices are monitors, printers, speakers and plotters. Monitors display soft copy output while printers provide hard copy printouts.
Digitalization: A Challenge and An Opportunity for BanksJérôme Kehrli
Today’s banking industry era is strongly defined by a word - digital. The urgency to act is only getting severe each day. Banks using digital technologies to automate processes, improve regulatory compliance, and transform the customer experience may realize a profit upside of 40% or more, while laggards that resist digital innovation will be punished by customers, financial markets, regulators, and may see up to 35% of net profit eroded, according to a McKinsey analysis.
The vital question to answer is, do we get digitalization right? Why is it getting extremely urgent to digitize?
Data security involves keeping information private by using methods to ensure confidentiality, integrity, and availability of data. It is important for businesses that hold confidential information. Data is backed up and stored hierarchically for safety. Software uses measures like intrusion detection systems, user IDs, passwords, biometrics, encryption, and digital signatures and certificates to protect data. Downloading pirated software poses legal and ethical issues and risks to users. Developers employ serial numbers, activation keys, copy protection, and hardware keys to protect their software and encourage users to register for updates and support.
A multimedia project requires a team with diverse skills, known as the multimedia skillset. These teams consist of roles like project managers, designers, programmers, writers, and specialists in areas like video and audio. Each team member has specific responsibilities to ensure the project is successfully developed, such as project managers coordinating the team and designers creating visuals and interfaces.

A multimedia system is characterized by the digital integration of various media types like text, graphics, sound, images and video. It allows for interactivity and uses computer networks for distribution. Ensuring quality of service is important for multimedia over networks due to the time sensitivity and synchronization needs of media. Compression techniques like lossy and lossless are used to reduce multimedia file sizes.
This document discusses using multimedia technologies for healthcare applications. It proposes a system for remote markerless human gait tracking over wireless networks for medical diagnosis and prognosis. The system uses video content analysis techniques like background subtraction and contextual classification to extract the human gait region from video frames without needing specialized equipment. It then jointly optimizes video encoding and wireless transmission to prioritize sending the extracted human gait region while meeting quality of service requirements over bandwidth-limited wireless networks. Experimental results using H.264 video compression demonstrate the effectiveness of the proposed remote healthcare system for applications like telemedicine.
The document summarizes information about the BHIM app, which was launched in December 2016 by the National Payments Corporation of India to facilitate e-payments directly through banks and simplify cashless transactions. BHIM allows users to send and request money, scan and pay for purchases, and view transactions. It has over 16 million downloads and supports multiple Indian languages. The app provides a secure way to transact between bank accounts but has limitations like daily transaction limits and no dedicated customer support.
This document discusses graphics and multimedia technology. It covers various topics related to graphics including different types of images (raster/bitmap and vector), color, file formats, and methods for obtaining images. Specifically, it describes raster images as composed of pixels and matrices, while vector images use objects like lines and shapes. It also discusses color palettes, resolution, dithering, and scanning, digitizing, and capturing images using cameras, scanners, and software tools.
This document discusses multimedia data compression. It explains that multimedia files like images, audio, and video take up significantly more storage space than text files. Data compression reduces the size of files by removing redundant data, saving storage space and allowing faster transfers. Compression is achieved through codecs, which are hardware or software that compresses and decompresses data. Compression can be lossless, allowing exact reconstruction of the original data, or lossy, which sacrifices some quality to achieve greater compression but does not allow exact reconstruction.
Multimedia refers to integrating various media types like text, graphics, audio, video digitally. Multimedia applications use a combination of media to deliver information interactively. Examples include websites, educational courseware, games. Multimedia development is the process of creating content combining different media types. It involves conceptualization, planning, production, and documentation phases. Various software are used to generate multimedia content for different applications in areas like advertising, education and entertainment.

RADIUS (Remote Authentication Dial In User Service) is a protocol that provides authentication, authorization and accounting functionality. It is commonly used for remote access to networks using modems or VPNs. The RADIUS protocol uses UDP and runs on ports 1812 and 1813. It operates on a client-server model where the client is typically a network access server and the server handles authentication requests from clients. RADIUS provides basic security through MD5 hashing of packets and a shared secret between clients and servers. However, it is vulnerable to sniffing and spoofing attacks.
Aide à la Planification Cellulaire dans un Réseau LTE (4G)Fatiha Merazka
Les réseaux de télécommunications ont pris de plus en plus d'importance dans notre vie quotidienne. Pour satisfaire au mieux les besoins et les intérêts des clients, les opérateurs doivent pouvoir offrir, au meilleur prix, des services d'excellente qualité. C'est dans ce cadre que s'inscrit le problème de planification cellulaire des réseaux qui consiste à optimiser les coûts engendréspar l'installation et l'utilisation du système. Une planification bien effectuée a pour effet de réduire le temps de mise en marche, le coût des dépenses d'investissement ainsi que le coût des dépenses opérationnelles.
Le réseau mobile est aujourd'hui un domaine en pleine effervescence. Pendant la dernière décennie, les évolutions de télécommunications ont explosé une nouvelle gamme de service qui a écarté les services classiques afin de satisfaire l’augmentation du nombre des utilisateurs et les exigences de taux de données élevés.
Cette motivation laisse les générations mobiles se succéder et se développer, de la technologie GSM vers un système de paquets tout IP optimisé dénommé Long Term Evolution (LTE).
L’opérateur se trouve, devant ces technologies, obligé de répondre à la croissance continue du trafic, avec une faible latence, une meilleure fiabilité, et une meilleure efficacité spectrale par rapport aux précédentes générations. Ces exigences ont stimulé les évolutions des réseaux pour mettre aujourd’hui le premier pas vers la quatrième génération avec LTE.
A ce stade, l’opérateur doit réduire le coût d’investissement et augmenter la qualité de service pour assurer la rentabilité.
Pour le faire il doit passer par les phases primordiales : dimensionnement et planification de système radio mobile, qui consiste à déterminer l'ensemble des composantes matérielles et logicielles de ces systèmes, les positionner, les interconnecter et les utiliser de façon optimale, en respectant, entre autres, une série de contraintes de qualité de service.
De façon générale, le problème de planification fait intervenir plusieurs sous-problèmes avec chacun un niveau de complexité différent. Dans ce travail, le sous-problème qui est traité concerne l'affectation des cellules aux commutateurs. Ce problème consiste à déterminer un modèle d'affectation qui permet de minimiser le coût d'investissement des équipements du réseau 4G, tout en maximisant l'utilisation faite des équipements du réseau 3G déjà en place.
Ainsi, la solution proposée est un modèle qui décrit la marche à suivre lors de la planification initiale d’un réseau LTE qui se base sur la planification et le dimensionnement des zones de suivi ou Tracking Area.
Dans ce projet, nous allons donc effectuer une planification et un dimensionnement des zones Tracking Area.

Les mathématiques appliquées et le calcul scientifique jouent un rôle croissant comme outils non évitables pour l’élaboration de recherches scientifiques et dans la conception de processus industriels. Le calcul scientifique reste pour toujours l’étape première de la voie du développement culturel et technique d’un pays donné.
Par ailleurs, le niveau de complexité des systèmes, généralement manipulés par les êtres humains que nous sommes, est très élevé à un niveau où toute avancée intellectuelle engendrera des retombés au niveau industriel tant que tous les processus de l’économie en dépendent.
En contre partie, la majorité des produits technologiques sont juste la solution immédiate de bon nombre de résolutions de requête de la vie courante. L'avènement de l'informatique et de ses produits, les langages de programmation de tout bord, de l'Internet et des télécommunications, à chacun ses infrastructures et ses protocoles, a révolutionné les méthodologies de travail des équipes et laboratoires de recherches. Les langages de développement informatique des outils et suites logiciels sont d’un grand secours aux travaux de modélisation et de simulation des processus.
Les mathématiques appliquées et l'informatique sont les moyens de conception (Modélisation et Simulation), plus encore, ils sont les vecteurs qui ont provoqué une amélioration nette dans les pratiques de tous les jours et aussi dans la vitesse de mise en œuvre de moyens exploitables.
Les langage de programmation, comme le C/C++, le FORTRAN ou le Python ont joué un grand rôle dans le cours de développement de beaucoup de procédés (Modélisation) et ont facilité la compréhension de beaucoup phénomènes (Simulation).

L’appareil phonatoire
Le générateur : air expulsé des poumons, traverse l’appareil
phonatoire comme un instrument à vent et crée la pression
nécessaire à la génération d’un signal acoustique.
Le vibrateur : L’air expulsé des poumons traverse la trachée
pour arriver dans le larynx où se trouve les cordes vocales. L’air
traversant le larynx met en vibration les cordes vocales. La
fréquence de vibration des cordes vocales est modulée en
fonction de leur degré de contraction.

Le résonateur : Ces vibrations sont modifiées par le passage de l’air dans les
différentes cavités qui composent le pharynx mais aussi dans les fosses
nasales. Ces résonateurs influent sur le son en atténuant certaines
fréquences et en amplifiant d’autres. La forme et le volume de ces cavités,
spécifiques au locuteur, modifient fortement le son produit.
Les modulateurs : les organes modulateurs que sont la langue, les lèvres et
la mâchoire sculptent, elles produisent les phonèmes qui composent la
parole. La position de ces différents organes est le mécanisme final qui
permet la production de parole articulée. Certains organes impliqués dans
la production de la parole se trouvent en partie visibles extérieur (lèvres,
langue, position des mâchoires).

27. Conclusion & Perspectives
● Conception et réalisation d'un système de sécurité biométrique basé sur le signal
parole ( monodimensionnel) et l'iris ( bidimensionnel),
● En perspective :
● Mise en place d’un système multi-agent pour le système d'authentification par
signal parole,
● Utilisation de la plate forme LabView pour le traitement d'images en temps réel
pour le système d'authentification par l'iris.
