Principles of Multimedia: A Comprehensive Guide by Ranjan Parekh
Principles of Multimedia is a book by Ranjan Parekh, a professor of computer science and engineering at Jadavpur University, Kolkata, India. The book covers the theoretical and practical aspects of multimedia systems, including text, image, graphics, audio, video and animation. The book also discusses the various multimedia standards, compression techniques, communication protocols, synchronization methods and applications.
The book has two editions: the first edition was published by Tata McGraw-Hill in 2006[^2^], and the second edition was published by Tata McGraw Hill in 2013[^1^]. The second edition has 825 pages and includes new topics such as multimedia security, digital watermarking, steganography, biometrics, multimedia databases and data mining. The book also provides several examples, exercises and case studies to illustrate the concepts and techniques.
The book is intended for undergraduate and postgraduate students of computer science and engineering, information technology, electronics and communication engineering, and related disciplines. It can also be used as a reference book by researchers and professionals working in the field of multimedia.

Multimedia systems are systems that use a combination of content forms like text, audio, video, pictures and animation to provide information or entertainment to the user. The video game console is just one example of the many multimedia systems that abound around us. Other examples include web browsers, video conferencing, e-learning, digital television, video on demand, online gaming, social media and virtual reality.
Multimedia applications can be classified into three categories based on their timing requirements[^2^]:
Streaming of stored multimedia content: This involves downloading a multimedia file from a server and playing it back on the user's device. Examples are watching a YouTube video or listening to a Spotify song. This type of application is delay-tolerant but requires a certain minimum bandwidth to avoid buffering.
Live streaming of multimedia content: This involves capturing and transmitting a multimedia content in real time. Examples are watching a live broadcast of a sports event or a news channel. This type of application is delay-sensitive but can tolerate some packet loss.
Real-time interactive multimedia communication: This involves exchanging multimedia content between two or more users in real time. Examples are video calling, online gaming or telemedicine. This type of application is both delay-sensitive and loss-tolerant and requires synchronization among the users.
Multimedia applications pose several challenges for the underlying communication networks, such as the Internet and wireless networks[^2^] [^3^]. Some of these challenges are:
Variability and unpredictability of network conditions: The Internet and wireless networks are subject to congestion, packet loss, delay, jitter and bandwidth fluctuations. These can affect the quality of service (QoS) and quality of experience (QoE) of multimedia applications.
Scalability and heterogeneity of users and devices: Multimedia applications have to cater to a large number of users with different preferences, capabilities and resources. For example, some users may have high-resolution screens while others may have low-resolution screens; some users may have high-speed connections while others may have low-speed connections; some users may have unlimited data
