Optimum Launches Q-Master Video for IPTV; Quality Analyzer for Next Generation Video Services.New Instrument Combines Perceptual Assessment Algorithms With Both Digital and Analog Video The original video recording method that stores continuous waves of red, green and blue intensities. In analog video, the number of rows is fixed. There are no real columns, and the maximum detail is determined by the frequency response of the analog system. Interfaces to Test and Measure Quality of IPTV (Internet Protocol TV) Also called "TV over IP," IPTV delivers scheduled TV programs and video-on-demand (VOD) via the IP protocol and digital streaming techniques used to watch video on the Internet. Services SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif. -- Developing perception-based quality assessment test and measurement tools, Optimum Holding Inc. (Optimum), today unveiled its Q-Master[TM] Video quality analyzer. The Q-Master solution is designed for telecommunications development engineers within System OEMs and Service Providers that need a flexible and cost-effective solution to test, measure and analyze the video quality generated and received by their multimedia products. A tool for laboratory environments, the Q-Master system uses ITU (International Telecommunication Union, Geneva, Switzerland, www.itu.ch) A telecommunications standards body that is under the auspices of the United Nations. Comprising more than 185 member countries, the ITU sets standards for global telecom networks. standard perceptual analysis to generate a Mean Opinion Score (MOS (1) (Metal Oxide Semiconductor) See MOSFET. (2) (Mean Opinion Score) The quality of a digitized voice line. It is a subjective measurement that is derived entirely by people listening to the calls and scoring the results from ) that represents the end-user's perception of quality from the device under test. These devices include codecs The following is a list of codecs. Audio codecs Non-compression formats
"The use of perceptual measurement algorithms enables System OEMs and Service Providers to test, measure and analyze the quality of the multimedia produced by their products from the end-users perspective," said Aart Konynenberg, Vice President of Optimum. "This unique measurement approach combined with Q-Master's flexibility and Microsoft Windows[R]-based user interface sets a new standard for quality test and measurement analyzers." Q-Master has both digital video and analog video interfaces and uses an industry proven objective perceptual video quality algorithm. It is therefore unique in its capability to assess video quality as perceived by the viewer; no other instrument currently available has such capability. The system has two main components - an I/O interface unit and a Windows-based network drive mapping application. The interface unit is easily portable and can be configured for multiple technologies including 10/100/1000 Ethernet, S-Video, Composite Video and others. This approach means that the interface unit can be installed anywhere in the network and be controlled by any authorized client PC. There is also a software only solution available which is file based only. Q-Master Video provides the following measurement parameters: an overall MOS score, Blocking, Blurring, Jerkiness, PSNR PSNR Peak Signal-to-Noise Ratio PSNR Peak Signal to Noise Rate , and PSNR vs. time, lost frames and/or packets, and many others. Additional algorithms will soon be available for no-reference video, lip-sync, etc.. The Windows-based GUI (Graphical User Interface) A graphics-based user interface that incorporates movable windows, icons and a mouse. The ability to resize application windows and change style and size of fonts are the significant advantages of a GUI vs. a character-based interface. provides many graphics and a video playback that enables quick and comprehensive quality assessment analysis. Pricing and Availability Q-Master Video is available today directly from Optimum for Video Quality Assessment starting at $34,990.00.
