Web Sports Enters Hd Arena

摘要

Ten years after U.S. networks began producing major league sports coverage in high-definition, HD sports has become ubiquitous. Now, networks and sports leagues are looking to bring the same experience to the Web by stepping up the quality of their online streaming, including the production of live HD streams for sports such as college football and basketball. The belief is that delivering higher-quality video will lead to longer viewing times and thus boost Web advertising and/or subscription revenues. While definitions of video quality on the Web tend to be subjective and engineers maintain there is no true HD video being streamed today, picture quality on the Web has unquestionably improved dramatically in the last two years. The 480-line-progressive, DVD-quality standard-def format is now commonplace, and 720-line-progressive-scan HD is quickly becoming the standard for premium fare.
