Digital Rapids' format-agile StreamZHD media encoding and streaming system was used by Washington, D.C. CBS affiliate WUSA-TV delivered the President's January 23 State of the Union Address live on the Web in high definition. The Web simulcast of the HD pool feed marks the first time a television station has streamed a live event publicly over the Internet in HD.
StreamZHD was used to encode the high definition pool feed of the event into Windows Media Video format (Microsoft's implementation of SMPTE VC-1) in real time at 1280x720 frame size and stream it for distribution. Two DRC-Stream encoding boards with Digital Rapids Stream software were also used to provide standard definition and smaller streams for users with lower-bandwidth connections.
WUSA-TV is part of Gannett Co. Inc. and has a rich history of pioneering achievements, including being the first television station in Washington, D.C. and sixth overall in the United States (first in a top-ten market) to present its local live newscasts in HD. W*USA's Web site, WUSA9.com, was also the first local broadcast station website to offer streaming video for local news.
WUSA-TV considers itself a leader in both HD television news and leveraging streaming video for local news on the Web, bringing the two technologies together is a logical step in delivering the best possible viewing experience to their audience. Digital Rapids StreamZHD was apparently well-suited to high-definition streaming, and the encoders reportedly performed flawlessly. WUSA-TV intends to make as much HD content as possible available through their Web site, and StreamZHD provides the technical capabilities to efficiently achieve this goal, the station said.
Digital Rapids Corp. noted that with the bandwidth available to content consumers constantly increasing, their expectations for the quality of web video have also increased, and discerning web viewers are no longer satisfied with just low-resolution content. It further that the the hardware-based pre-processing and outstanding encoding performance of StreamZHD make it the ideal platform for delivering top-quality video streams in both standard and high definition, and we're excited to be at the heart of WUSA-TV's ground-breaking streaming strategy.
StreamZHD combines powerful, format-agile hardware for HD/SD capture and pre-processing with the intuitive Stream software interface, delivering high-quality, professional multi-format media encoding, transcoding and streaming. The advanced, hardware-based video processing features " including motion adaptive de-interlacing and 3D motion-adaptive noise reduction " enable optimum quality and the most efficient use of bandwidth in the compressed result.
