Download or read book Transporting Compressed Digital Video written by Xuemin Chen and published by Springer Science & Business Media. This book was released on 2005-11-28 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of Transporting Compressed Digital Video is to introduce fundamental principles and important technologies used in design and analysis of video transport systems for many video applications in digital networks. In the past two decades, progress in digital video processing, transmission, and storage technologies, such as video compression, digital modulation, and digital storage disk, has proceeded at an astounding pace. Digital video compression is a field in which fundamental technologies were motivated and driven by practical applications so that they often lead to many useful advances. Especially, the digital video-compression standards, developed by the Moving Pictures Expert Group (MPEG) of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), have enabled many successful digital-video applications. These applications range from digital-video disk (DVD) and multimedia CDs on a desktop computer, interactive digital cable television, to digital satellite networks. MPEG has become the most recognized standard for digital video compression. MPEG video is now an integral part of most digital video transmission and storage systems. Nowadays, video compression technologies are being used in almost all modern digital video systems and networks. Not only is video compression equipment being implemented to increase the bandwidth efficiency of communication systems, but video compression also provides innovative solutions to many related vid- networking problems. The subject of Transporting Compressed Digital Video includes several important topics, in particular video buffering, packet scheduling, multiplxing and synchronization.
Download or read book Rate Quality Optimized Video Coding written by Yoo-Sok Saw and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rate-Quality Optimized Video Coding discusses the matter of optimizing (or negotiating) the data rate of compressed digital video and its quality, which has been a relatively neglected topic in either side of image/video coding and tele-traffic management. Video rate management becomes a technically challenging task since it is required to maintain a certain video quality regardless of the availability of transmission or storage media. This is caused by the broadband nature of digital video and inherent algorithmic features of mainstream video compression schemes, e.g. H.261, H.263 and MPEG series. In order to maximize the media utilization and to enhance video quality, the data rate of compressed video should be regulated within a budget of available media resources while maintaining the video quality as high as possible. In Part I (Chapters 1 to 4) the non-stationarity of digital video is discussed. Since the non-stationary nature is also inherited from algorithmic properties of international video coding standards, which are a combination of statistical coding techniques, the video rate management techniques of these standards are explored. Although there is a series of known video rate control techniques, such as picture rate variation, frame dropping, etc., these techniques do not view the matter as an optimization between rate and quality. From the view of rate-quality optimization, the quantizer is the sole means of controling rate and quality. Thus, quantizers and quantizer control techniques are analyzed, based on the relationship of rate and quality. In Part II (Chapters 5 and 6), as a coherent approach to non-stationary video, established but still thriving nonlinear techniques are applied to video rate-quality optimization such as artificial neural networks including radical basis function networks, and fuzzy logic-based schemes. Conventional linear techniques are also described before the nonlinear techniques are explored. By using these nonlinear techniques, it is shown how they influence and tackle the rate-quality optimization problem. Finally, in Chapter 7 rate-quality optimization issues are reviewed in emerging video communication applications such as video transcoding and mobile video. This chapter discusses some new issues and prospects of rate and quality control in those technology areas. Rate-Quality Optimized Video Coding is an excellent reference and can be used for advanced courses on the topic.

Download or read book Multidimensional Transcoding for Adaptive Video Streaming written by Jens Brandt and published by Logos Verlag Berlin. This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transmission of digital audio and video streams is one of the major applications in future wireless networks. Increasing bandwidths and processing power make it possible to receive video streams almost everywhere. But the classes of mobile devices vary from multimedia enabled mobile phones to high-end notebooks. The varying capabilities of these devices such as display resolution, processing power, memory size or network connection result in a great heterogeneity of client devices. To support as many different devices as possible, some kind of video adaptation is needed. In this book we propose a multimedia gateway system that provides a video adaptation service to its clients. The main focus, however, is the adaptation process itself. Therefore, we investigated different compressed domain transcoding techniques and identified three adaptation dimensions that need to be considered to support a great heterogeneity of devices. Based on these observations a novel transcoding architecture is presented that smartly combines existing transcoding mechanisms to build a multidimensional compressed domain transcoder.

Download or read book Heterogeneous Transcoding for Next Generation Multimedia Video Codecs for Efficient Communication written by Shreyanka Subbarayappa and published by . This book was released on 2022 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Innovations in the communication systems and technology are growing tremendously and the growth seen is unimaginable in the last forty years. In multimedia communication systems, technology has transformed from analog television to digital television in the video domain. Mobile phones are known as smart phones as they are used, not only to make voice calls, but also used to send emails, video calls, transfer data, GPS, taking pictures and so on. Due to the wide spread user applications, compression on data becomes important to save system resources. Video has occupied 75% of major traffic of data transfer and is expected to cover 80% by 2021 [4]. Video is also continuously increasing in size from standard-definition (SD) to ultra-high definition (UHD - 4K, 8K and 12K) video. More data or size in video requires higher transmission bandwidth or more disk space to store, which is very expensive. This drives into the betterment in compression and hence a demand for a new codec. Several algorithms are implemented to achieve compression of Image or Video with respect to the user's demand on the quality of output as well as application it is used for. These algorithms working together are classified in terms of codecs and we use different codecs for different applications. Advances in video compression technology are used to reduce the utilization of system resources, like processing time, memory use, network bandwidth and battery life. This is possible by reducing the complexity of the video codecs without compromising on the output video quality [2][3][5]. There are two distinct lines in the future video coding technology development work. EVC driven by MPEG team [126] and Versatile Video Codec (VVC) [7][8] driven by Joint Video Exploration Team (JVET). These codecs are the extended versions with advances in compression technologies when compared to the prior video codecs or reference codecs HEVC and H.264. This thesis is fundamentally and entirely devoted to the theory and design of different algorithms used in present and future video codecs to obtain efficient implementation and reconstruction of codec outputs. It also addresses the most recent codecs being developed, i.e. EVC and VVC. Transcoding being one of the main applications in video technologies is implemented and studied between these four codecs.
