Introduction To Ip Video; Digitization, Compression And Transmission

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.
