This paper presents the study of running several core multimedia applications on a simultaneous multithreading (SMT) architecture and derives design principles for multimedia software engineering. The multimedia workloads range from memory to computational-bounded kernels. A performance metric to evaluate effective SMT performance gain is introduced, and compared to similar metrics on symmetric multiprocessor (SMP) systems. In addition, we analyze and compare SMT versus SMP systems, and highlight the advantages in the studied applications. The results indicate that sharing the cache in SMT processors can provide better cache locality and thus better performance although sharing the cache can introduce cache conflicts and reduce the actual cache size available for each logical processor. We also propose "mutually beneficial prefetching" - a technique to schedule threads so that they prefetch data for each other in order to reduce cache miss penalty.

A Web service is a programmable Web application accessible using standard Internet protocols. A three-layer architecture has been suggested for Web services: service providers, service brokers, and service requesters. We propose a SOAP-oriented component-based framework to support device-independent multimedia Web services. Two intelligent agents are introduced and embedded into a proxy server and service provider server, respectively. Separating metadata from multimedia content leads to enhance SOAP flexibility. Composite capability/preference profile-based user profile management provides an easy and flexible way to split and adapt multimedia services to appropriate composite devices as well as increasing the flexibility for users to manage multiple devices. Together with an XML/XSL strategy, we ensure device independency of the system. By utilizing local caches, our agents enable the caching and streaming of multimedia transportation. In addition, our framework seamlessly incorporates cutting-edge technologies relating to Web services: SOAP, XML/XSL, and CC/PP.

In applications such as scientific and medical visualization, highly detailed polygonal meshes are needed. Rendering these polygonal meshes usually exceeds the capabilities of graphics hardware. To improve rendering efficiency and maintain proper interactivity, the polygonal mesh simplification technique is commonly used to reduce the number of polygons of the mesh and construct a multiresolution representation. We propose a new and simple constraint scheme based on the quadric error metric proposed by Garland and Heckbert (1997, 1998) to preserve face colors and boundary edges during the simplification process. In addition, our method generates progressive meshes that store the polygonal mesh in a continuous multi-resolution representation. According to our experimental results, this new method is successful in preserving face colors and boundary edges. Moreover, we compare the latency of resolution changes for progressive meshes of various models.

Massive Multi-player Online Games (MMOGs) are rapidly gaining in popularity, as the access to high bandwidth connectivity becomes a commodity in the consumer market. With player subscriptions for popular games reaching seven digit numbers and concurrent player participation in the hundreds of thousands, new high-performance adaptive frameworks, which aid system programmers, are required. Primary research challenges that have to be addressed are compensating network latency and jitter, keeping system-wide data consistent, enabling fair resource sharing and interaction between game players, and expanding the scale of the system as the number of players increases. A global timestamp based approach is presented and describes issues and implementation approaches based on a high-level object-oriented real-time programming methodology called the time-triggered message-triggered object (TMO) programming scheme.

Interactive digital TV offers a wide range of possibilities to enhance the interplay and mutual influence between the viewer, broadcaster and application provider. The multimedia home platform (MHP) is a standard that allows one to develop interactive applications in a hardware platform independently. In order to evaluate the usability and appropriateness of current MHP implementations, we developed an interactive application on basis of the MHP standard. Generally, the technology is mature, although some minor technical programs have to be solved. Currently, no appropriate emulators for MHP applications are available, which leads to considerable costs for testing MHP applications.
