Mobile Tv Coming to Canada?

Simon Fraser University (SFU) doctorate student Cheng-Hsin Hsu, along with SFU graduate students Yi Liu and Cong Ly, and their supervisor Mohamed Hefeeda, has designed algorithms and prototypes of mobile TV base stations that enable devices such as cell phones to receive TV programming. Similar technologies are already available in Europe and Asia, but Hsu says those technologies are very sensitive and unreliable. "The technology has been there for a couple of years, but not here," Hsu says. "There are clearly some problems with it that prevent its deployment in North America. We are trying to optimize the broadcast networks to a stage where Canadian TV companies will consider them."
Hsu's research has resulted in improved mobile TV broadcast performance and cell phones that broadcast more channels at once while reducing their channel-switching delay. Hsu also has improved the overall broadcast quality and extended battery life, which are features that are missing in mobile broadcast TV systems overseas. Hsu is currently working to establish mobile TV broadcasts through Wi-Fi and other wireless networks.
