Personal computing is currently undergoing radical enhancements with the current technological advancements that have been made in the areas of high resolution displays, GUIs (graphic user interfaces), high quality sound and full motion video. Multimedia stands at the convergence of these technological advances. The pervasiveness of networks will result in a new generation of distributed services that include multimedia as the fundamental characteristic. The current hyper-activity in the commercial arena is testimony to the future of distributed mu1timedia services. The anticipation of the data superhighways has led to an industrial scramble filled with takeovers and acquisitions as companies battle to acquire the infrastructure that will set the scene for the services of the future.

Much of the current research involving the delivery of multimedia data focuses on the need to maintain a constant Quality of Service (QoS) throughout the lifetime of the connection. Delivery of a constant QoS requires that a guaranteed bandwidth is available for the entire connection. Techniques, such as resource reservation, are able to provide for this. These approaches work well across networks that are fairly homogeneous, and which have sufficient resources to sustain the guarantees, but are not currently viable over either heterogeneous or unreliable networks. To cater for the great number of networks (including the Internet) which do not conform to the ideal conditions required by constant Quality of Service mechanisms, this thesis proposes a different approach, that of dynamically adjusting the QoS in response to changing network conditions. Instead of optimizing the Quality of Service, the approach used in this thesis seeks to ensure the delivery of the information, at the best possible quality, as determined by the carrying ability of the poorest segment in the network link. To illustrate and examine this model, a service-adaptive system is described, which allows for the streaming of multimedia audio data across a network using the RealTime Transport Protocol. This application continually adjusts its service requests in response to the current network conditions. A client/server model is outlined whereby the server attempts to provide scalable media content, in this case audio data, to a client at the highest possible Quality of Service. The thesis presents and evaluates a number of renegotiation methods for adjusting the Quality of Service between the client and server. An A djusted QoS renegotiation method algorithm is suggested, which delivers the best possible quality, within an acceptable loss boundary.

As a means for understanding a wide range of multimodal phenomena, multimodal analysis poses methodological challenges for the novice researcher intent on investigating multimodal communication, especially communication that involves multimodal musical performance (MMP), an understudied communicative act. As a response to these challenges, this project examines three approaches to multimodal analysis identified by Carey Jewitt in The Routledge Handbook of Multimodal Analysis as central to studying multimodality writ large: social-semiotic multimodal analysis (SSMA), multimodal discourse analysis (MDA), and multimodal interactional analysis (MIA). However, while these approaches each provide a theory and key concepts for analysis, they lack a practicable methodology—necessary for the novice research—and, thus, provide no concrete way to pursue multimodal analysis or to assess the strengths and deficits of a particular approach when applied to the analysis of MMPs. In this project, I conduct a critical analysis that includes a theoretical and pragmatic examination of these approaches to multimodal analysis and assess them for strengths and deficits in terms of a particular MMP because such a performance is an important and under-explored variety of multimodal text. Thus, this project asks three questions of each approach and its methods: 1) What are the strengths of each approach to multimodal analysis of musical performance as multimodal communication? 2) What are the deficits of each approach to multimodal analysis of musical performance as multimodal communication? 3) And, finally, given the strengths and deficits of competing approaches to multimodal analysis of musical performance as multimodal communication, what do we need moving forward in order to fully, robustly, and capaciously analyze and understand musical performance as multimodal communication? I respond to these questions by devising a synthesized, practicable methodology for each approach, one derived from the work in key chapters in The Routledge Handbook identified by Jewitt as employing a specific approach. I apply each of these methodologies to a single musical performance: video footage from Bob Dylan’s July 25, 1965 performance at the Newport Folk Festival—which is often seen as a pivotal moment in popular music history—collected on the 2011 blu-ray release of Murray Lerner’s concert film The Other Side of the Mirror: Bob Dylan Live At Newport Folk Festival 1963-1965. I assess the results of my application of each methodology and its methods to determine the strengths and deficits of each approach for analyzing MMPs. Finally, I offer two options to bolster strengths and address deficits of these three approaches to the multimodal analysis of MMPs, one crafted from combining approaches, and one crafted from a new perspective—that of sonic imaginations (Sterne)—thus informing methodology with attention to the sonic aspects of MMPs. This dissertation offers three key results important for the novice researcher. First, it provides a practicable methodology for each approach, a necessary step in the process of assessing an approach's strengths and deficits. Second, it offers the novice researcher insight into each methodology’s potential. For instance, analyses indicated that SSMA possesses, among its five strengths, a focus on the sign-maker, while at the same time, it possesses, among its three deficits, no mechanism through which to consider the multiple sign-makers involved in an MMP. Similarly, MDA possesses, among its six strengths, a focus on the multimodal phenomenon, while at the same time, it possesses, among its four deficits, a lack of a systematic means for delineating levels of discourse. And, MDA possesses, among its five strengths, a focus on interaction between social actors involved in an MMP, while at the same time, it possesses, among its five deficits, a requirement for a considerable amount of guesswork on the part of the researcher. Third, while demonstrating that no approach to multimodal analysis offers a “best” methodology for the analysis of MMPs, this dissertation offers two directions for methodological inspiration. It concludes that, through a deliberate courting of emotion by tapping into elements of music criticism and through a deliberate courting of messiness by embracing the union of emotion and analysis, methodologies for analysis can be crafted that align with the demands of MMPs. / A Dissertation submitted to the Department of English in partial fulfillment of the requirements for the degree of Doctor of Philosophy. / Fall Semester 2017. / October 25, 2017. / Composition, Methodologies, Multimodal Analysis, Music, Musical Performance, Sound Studies / Includes bibliographical references. / Kristie Fleckenstein, Professor Directing Dissertation; Davis Houck, University Representative; Kathleen Blake Yancey, Committee Member; Michael Neal, Committee Member.
