报告主要内容简介

Driven by the technological advancements in wireless infrastructures and hand-held devices, recent years have witnessed the proliferation of real-time video applications over smartphones (e.g., video call, mobile gaming, live sports streaming, etc.). However, streaming high-quality real-time videos with the limited radio resources is challenging due to the time-varying channel status and stringent service requirements. Therefore, it is of vital significance to investigate the performance optimization for real-time video streaming over unreliable communication networks. This seminar explores the problem in the following aspects: 1) multipath video transmission over heterogeneous wireless networks; 2) high-frame-rate wireless video delivery; 3) energy-efficient video streaming to mobile devices; 4) real-time video communication with TCP (Transmission Control Protocol).
