This chapter comprehensively covers the topic of the Region-of-Interest (ROI) processing and coding for multimedia applications. The variety of end-user devices with different capabilities, ranging from cell phones with small screens and restricted processing power to high-end PCs with high-definition displays, have stimulated significant interest in effective technologies for video adaptation. Therefore, the authors make a special emphasis on the ROI processing and coding with regard to the relatively new H.264/SVC (Scalable Video Coding) standard, which have introduced various scalability domains, such as spatial, temporal, and fidelity (SNR/quality) domains. The authors’ observations and conclusions are supported by a variety of experimental results, which are compared to the conventional Joint Scalable Video Model (JSVM).

Comprehensive Survey

In recent times, enormous advancement in communication as well as hardware technologies makes the video communication very popular. With the increasing diversity among the end using media players and its associated network bandwidth, the requirement of video streams with respect to quality, resolution, frame rate becomes more heterogeneous. This increasing heterogeneity make the scalable adaptation of the video stream in the receiver end, a real problem. Scalable video coding (SVC) has been introduced as a countermeasure of this practical problem where the main video stream is designed in such a hierarchical fashion that a set of independent bit streams can be produced as per requirement of different end using devices. SVC becomes very popular in recent time and consequently, efficient and secure transmission of scalable video stream becomes a requirement. Watermarking is being considered as an efficient DRM tool for almost a decade. Although video watermarking is regarded as a well focused research domain, a very less attention has been paid on the scalable watermarking in recent times. In this book chapter, a comprehensive survey on the scalable video watermarking has been done. The main objective of this survey work is to analyse the robustness of the different existing video watermarking scheme against scalable video adaptation and try to define the research problems for the same. Firstly, few existing scalable image watermarking schemes are discussed to understand the advantages and limitations of the direct extension of such scheme for frame by frame video watermarking. Similarly few video watermarking and some recent scalable video watermarking are also narrated by specifying their pros and cons. Finally, a summary of this survey is presented by pointing out the possible countermeasure of the existing problems.

This chapter covers the topic of making use of scalable video content in streaming frameworks and applications. Specifically, the recent standard H.264/SVC, i.e., the scalable extension of the widely used H.264/AVC coding scheme, and its deployment for adaptive streaming, the combined activities of content adaptation and streaming, are considered. H.264/SVC is regarded as a promising candidate to enable applications to cope with bandwidth variations in networks and heterogeneous usage environments, mainly diverse end device capabilities and constraints. The relevant coding and transport principles of H.264/SVC are reviewed first. Subsequently, a general overview of H.264/SVC applications is given. The chapter then focuses on presenting architectural/implementation options and applications of H.264/SVC for adaptive streaming, emphasizing the aspect of where, i.e., on which network node and on which layer in the networking stack, in the video delivery path the content adaptation can take place; also, methods of content adaptation are covered. This pragmatic perspective is seen as complementing more general discussions of scalable video adaptation issues in the existing literature.
