H.264/MPEG-4 AVC is the latest video-coding standard jointly developed by the Video Coding Expert Group (VCEG) of ITU-T and the Moving Picture Expert Group (MPEG) of ISO/IEC JTC1. It uses to enhance significantly the compression rate when compared to previous standard in the field, especially the largely adopted MPEG-2 one. However, MPEG-2 is presently overwhelmed used by the industry, and as a consequence most of the existing digital video material is encoded in this standard. This paper discuss efficient way to convert existing MPEG-2 and beyond it MPEG-1 and MPEG-4 visual material, toward H.264, what is a critical factor toward a successful H.264 deployment.

Abstract This essay explores the inscription of codes and intersemiotics in Wharton's The Age of Innocence and its 1993 adaptation by Martin Scorsese, and analyzes the effects derived from them. It begins by showing how the sense of ironical distance that prevails in the first chapters of the novel is redefined in the film, especially in the brilliant title sequence and opening scene that set a different tone, more likely to trigger identification with the characters and produce emotion, instead of underscoring convention. Apart from the opera motif, other intersemiotic connections that function differently in the book and its adaptation deserve to be examined. Thus the essay studies how pictorial quotations abound in the film, more than in Wharton's novel, especially works by James Tissot that convey a sense of ambiguity, while other paintings are related to the transcoding of violence and mystery. It then discusses the subversive emphasis on frames and framing and the reference to tableau vivant, before dwelling on facets of textual and filmic reflexivity.

Over the past decade, non-profit organizations have used alternate reality games (ARG) to raise awareness on the risks of climate change. This new form of content creation leverages the mass adoption of mobility and real-time access to social networks, tools and resources that have previously been unavailable to technologists, designers, and artists who produce ARGs. This dissertation explores how advances in Human Computer Interaction can be applied to the design of these ARGs. Focusing on the narrative structure, this multiple case study asks, what are the considerations alternate reality game designers have (if any), when designing the games, they make? The validity and utility of this research is presented through three cases: Future Coast (2014) explores the future of climate change, supported by the National Science Foundation; The Disaster Resilience Journal (2014) catalogued forty-two days of journal entries emphasising emergency preparedness, supported by the European Commission’s Department for Humanitarian Aid & Civil Protection; and Techno Medicine Wheel (2009) teaches aboriginal values as living history, supported by The Aboriginal Media Lab in Cyber Space. Within each case I analyze two units of data 1) the designers’ interviews and 2) the game’s trajectory. Previous research on mixed reality experiences (Benford et al. 2011) focused primarily on the trajectory of plot points through the duration of the game. This study contributes a unique focus, addressing characteristics such as plot points that engage fans in and out of collective problem solving activities. The study also includes a clear description of the benefits of working under the guiding influence of a non-profit organizations. Finally, this study provides methodological strategies to collect and analyze ARG design, post-mortem. Thus, findings provide certain substantial characteristics that demonstrate how the practices of designers are transcoding place through their creative use of digital media.

We earlier proposed a flexible multimedia system (FMS) that is able to guarantee end-to-end QoS according to priority of parameters and consensus policy. On interconnected computer networks, we can communicate with each other using real-time media such as audio and video by distributed multimedia system that can integrate various realtime and discrete media data. The multimedia system is required to realize end-to-end quality of service (QoS) guarantee functions. When users communicate with each other on interconnected different bandwidth networks, if the system can use translator or mixer functions that are defined by RTP it will be able to guarantee more flexible QoS. In addition, the system is able to organize various multimedia services dynamically. The FMS is a mobile agent based system, therefore the system will be able to organize a translator or mixer dynamically. In this paper we discuss QoS guarantee functions using mobile agent and re-design our prototype system to use mobile transcoding functions for flexible multimedia communication.

Transcoding is a technique employed by network proxies to dynamically customize multimedia objects for prevailing network conditions and individual client characteristics. Transcoding can be performed along a number of different axes and the specific transcoding technique used depends on the type of multimedia object. Our goal in this paper is to understand the nature of typical Internet images and their transcoding characteristics. We focus our attention on transcodings intended to customize an image for file size savings. Our results allow the developers of a transcoding proxy server to choose the appropriate transcoding techniques for the important classes of Internet images. We analyze the characteristics of images available on the Web through a representative trace. We show that most GIF images accessed on the Internet are small

Abstract: Broadcasting/multicasting is more advantageous than multiple unicast as it reduces the communication cost. And supporting terminals with differing media capabilities is expected to be important and to grow in importance. However, considering user terminal requirements during multicast communication is not

The adaptation of video according to the heterogeneous and dynamic resource constraints on networks and devices, as well as on user preferences, is a promising approach for universal access and consumption of video content. For optimal adaptation that satisfies the constraints while maximizing the utility that results from the adapted video, it is necessary to devise a systematic way of selecting an appropriate adaptation operation among multiple feasible choices. This paper presents a general conceptual framework that allows the formulation of various adaptations as constrained optimization problems by modeling the relations among feasible adaptation operations, constraints, and utilities. In particular, we present the feasibility of the framework by applying it to a use case of rate adaptation of MPEG-4 video with an explicit modeling of adaptation employing a combination of frame dropping and discrete cosine transform coefficient dropping, constraint, utility, and their mapping relations. Furthermore, we provide a description tool that describes the adaptation-constraint-utility relations as a functional form referred to as a utility function, which has been accepted as a part of the terminal and network quality of service tool in MPEG-21

This paper focuses on one of the author’s compositions, Outer Space, conceived using transcoding techniques between musical and visual parameters, such as the relative percentage of black and white dots per frame and the difference between the position of the dots from one frame to another.
