This book explains the fundamentals of video, how it is digitized and compressed and the basics of video streaming. You will learn why IP digital video has replaced many analog and digital video systems. Industry standard IP video systems can be more cost effective and flexible than dedicated and/or proprietary video systems. Using IP video allows for equipment and software cost reduction, increased ability to control video services, and provides new media capabilities. The popular analog and digital video formats are described along with how video signals are captured and converted from analog to digital form (video digitization). Because the amount of digital information that is needed to represent high-quality raw digital video requires require several Gigabits per second, digital video is compressed to allow transmission through data networks such as the Internet. You will learn that video compression is the process of reducing the amount of transmission bandwidth or data transmission rate using intra-image (spatial) or by inter-image (temporal) compression techniques. When compressed, a video signal can be transmitted on circuits with relatively narrow channel bandwidth or using data rates 50 to 200 times lower than their original uncompressed form. You will discover how video streaming systems allow for the efficient sending of packet video through data networks that may delay or loose packets. Also, you will learn how video capturing is used to receive, code and to storing video images. How video formats are converted from different formats and mediums (e.g. video to movies) is described including pullup and pulldown systems. Learn about the different types of multimedia file formats and how they sequence and group of media information elements (e.g. blocks of digital audio and digital video) within a block of data (file) or as organized on a sequence (stream) of information. Find out about different types of streaming protocols and how they are used to deliver and control the real-time delivery of media (such as audio and or video streaming). Digital video quality measurements and monitoring is explained including tiling, error blocks, smearing, jerkiness, artifacts (edge busyness) and object retention.

You will learn that audio compression is the process of reducing the amount of transmission bandwidth or data transmission rate using waveform coding, perceptual coding or voice compression techniques. When compressed, an audio signal can be transmitted on circuits with relatively narrow channel bandwidth or using data rates 4 to 16 times lower than their original uncompressed form. There are several different IP Audio compression methods and protocols that are available such as MP3 and AAC. Explained are complexity and quality tradeoffs along with common problem areas and risks with sending IP Audio. You will discover how audio streaming systems allow for the efficient sending of packet audio through data networks that may delay or loose packets.

John Mauchly, J. Presper Eckert, Jr., and their team built ENIAC (Electronic Numerical Integrator and Computer) in 1946, the first modern stored-program electronic computer. They built it primarily to design weapons during the Second World War. Since then, computers have entered every facet of our daily life. Nowadays, we use computers extensively to process data in banks, government offices, and commercial establishments. We use them to book train tickets, airline tickets, and hotel rooms. They control systems such as satellites and moon landers in real-time. They create complex graphics and animation. They synthesize speech and music. They write essays and draw pictures. They control Robots. Publishers use them as tools. They are used to play video games. Many devices, such as audio and video tape recorders and film cameras, have died and been replaced by digital devices. They have eliminated many jobs, such as type-setters, and created new jobs, such as programmers, requiring better skills. It is fascinating to trace this history. This book recounts the history of modern computing as a sequence of seventy-two anecdotes, beginning with how engineers at the University of Pennsylvania built the modern stored program computer ENIAC in 1946 and ends with the story of the evolution of ChatGPT and Gemini, the generative large language model neural network released between 2022 and 2024 that give natural language answers to natural language questions, write essays, compose poems, and write computer programs. The anecdotes in this book are short. Each anecdote is between 1500 and 2500 words and recounts the story of an important invention in the evolution of modern computing and the people who innovated. There are seventy-two anecdotes in this book. The anecdotes cover the history of computer hardware, software, applications, computer communications, and artificial intelligence. The set of anecdotes on hardware systems describes, among others, the history of the evolution of computers, such as the IBM 701, CDC 6600, IBM 360 family, Digital Equipment Corporation's PDP series, Apple – the early personal computer, and Atlas – a pioneering British computer, IBM PC, Connection Machine, Cray series supercomputers, computing cluster Beowulf, IBM Roadrunner – the fastest and the most expensive ($ 600 million) computer in the World in 2022, Raspberry Pi – the cheapest ($35) computer. The group of anecdotes on software describes the evolution of Fortran, COBOL, BASIC, Compatible Time-shared systems, Unix, CP/M OS, MS-DOS, Project MAC, and open-source software movement, among others. Some anecdotes are on computer applications, such as Data Base Management Systems (DBMS), spreadsheets, cryptography, and Global Positioning Systems (GPS). The anecdotes on computer communications recount the evolution of computer communication networks, such as ALOHAnet, Ethernet, ARPANET, and the Internet, among others. The anecdotes on Artificial Intelligence (AI) start with "Who coined the word Artificial Intelligence?" and recounts early chess-playing programs, the evolution of neural networks, Expert Systems, and the history of chatbots and Robots. These anecdotes are similar to a short story collection. A reader may read them in any order. Each anecdote is self-contained, and readers may read the one that interests them. The language used in the book is simple, with no jargon. Anyone with a high school education can understand the material in this book. KEY FEATURES • The book recounts the history of modern computing as a series of 72 anecdotes • Each anecdote tells the story of an important event in the history of computing • Each anecdote describes an invention and those who invented • Each anecdote is self-contained and may be read in any order • Suitable for a general reader with a high school education TARGET AUDIENCE • Students Pursuing Computer Science & IT Courses • IT Professionals • 10+2 students...
