Real-time High-definition Streaming System over the Internet
The NCHC has created a web-based image and video monitoring system to support high-definition multimedia streaming over the Internet. This system supports the streaming of high-definition video and images in digital video (DV) and high-definition video (HDV) formats. It also supports the streaming of audio and video simultaneously. Various stream formats including M-JPEG, Flash, and MPEG-2 are supported as well. Additionally, it is able to load monitor the streaming server in real-time. Users of this system can easily and conveniently watch high-definition real-time streaming video using the Internet Explorer (IE), Firefox, or most other web browsers.
The system supports definitions of 720x480 in DV mode, 1280x720, 1280x1080, and 1440x1080 in HD mode, and 1920x1080 in Full HD mode. The system is also able to quickly compress large video files (e.g. 20 Mb/sec ~ 30Mb/sec) into much smaller files sizes (e.g. 720 Kb/sec ~ 1 Mb/sec) using the M-JPEG, Flash, and MPEG-2/4 codecs. This allows for the efficient real-time streaming of compressed video feeds via ADSL, Cable modem, and fiber to the home (FTTH) and/or fiber to the building (FTTB).
Most similar systems can only support low-definition video streaming (e.g. QCIF (176x144), CIF (352x288), NTSC (510x492), PAL (500x582), or VGA (640x480)). Our system, on the other hand, provides an outstanding solution for users who require real-time high-definition streaming for applications such as environmental observation (e.g. ECO Grid), high-definition network theater, and the networking of publications and new products.
