HaiVision Systems and Zixi have successfully broadcast of live HD video over the public Internet.
The broadcasts were transmitted from the Columbia University Medical Center in New York City to remote studio facilities in the United States and simultaneously to several other sites worldwide, where viewers accessed video using either a Web browser or an Internet-enabled IP set-top box. The real-time HD broadcasts were transmitted over the Internet using Zixi’s IVDN platform to recover and reorder lost packets in real time providing instant start, continuous delivery of video to studio, set-top boxes, and PCs without any sacrifice in video quality.
The HD (1080i) feeds were transmitted between the CUMC and convention centers using HaiVision’s MAKO-HD H.264 HD codecs. At other locations worldwide, audiences simultaneously viewed the transmission using software decoders on standard PCs. The Internet services at both ends were standard general-purpose ISP connections, with the stream serviced by the Zixi IVDN platform. In a side-by-side comparison at the receiving studio, the video quality delivered over the Zixi IVDN was indistinguishable from the signal received via satellite and dedicated fiber connections.
