Abstract
  • Traditional approaches to streaming H.264 video over a network typically rely on a single method of transport (i.e., reliable or unreliable) and/or use static values for parameters that can have a significant negative impact on the perceptual quality of the received video. This dissertation presents a dynamic method for wireless channel selection during video streaming, and explores the latency and QoE improvements yielded by the FDSP dual streaming method. The increased workload that results from these dynamic methods can lead to a counterproductive impairment of streaming performance, and therefore requires efficient use of the multiple cores typically present in both sender and receiver (or server and client). This dissertation therefore presents a performance cost model which can be used to guide the parallelization of specific types of client or server-side streaming components -- specifically, programs containing non-DOALL loops that have inter-iteration data dependences which constrain their parallelism.
