  • Analog/SDI to SDI/Optical Converter with TBC/Frame Sync User Guide
    Analog/SDI to SDI/Optical Converter with TBC/Frame Sync User Guide ENSEMBLE DESIGNS Revision 6.0 SW v1.0.8 This user guide provides detailed information for using the BrightEye™1 Analog/SDI to SDI/Optical Converter with Time Base Corrector and Frame Sync. The information in this user guide is organized into the following sections: • Product Overview • Functional Description • Applications • Rear Connections • Operation • Front Panel Controls and Indicators • Using The BrightEye Control Application • Warranty and Factory Service • Specifications • Glossary BrightEye-1 BrightEye 1 Analog/SDI to SDI/Optical Converter with TBC/FS PRODUCT OVERVIEW The BrightEye™ 1 Converter is a self-contained unit that can accept both analog and digital video inputs and output them as optical signals. Analog signals are converted to digital form and are then frame synchronized to a user-supplied video reference signal. When the digital input is selected, it too is synchronized to the reference input. Time Base Error Correction is provided, allowing the use of non-synchronous sources such as consumer VTRs and DVD players. An internal test signal generator will produce Color Bars and the pathological checkfield test signals. The processed signal is output as a serial digital component television signal in accordance with ITU-R 601 in both electrical and optical form. Front panel controls permit the user to monitor input and reference status, proper optical laser operation, select video inputs and TBC/Frame Sync function, and adjust video level. Control and monitoring can also be done using the BrightEye PC or BrightEye Mac application from a personal computer with USB support.

  • NTSC Is the Analog Television System in Use in the United States and In
    NTSC is the analog television system in use in the United States and in many other countries, including most of the Americas and some parts of East Asia It is named for the National Television System(s) Committee, the industry-wide standardization body that created it. History The National Television Systems Committee was established in 1940 by the Quick Facts about: Federal Communications Commission An independent governmeent agency that regulates interstate and international communications by radio and television and wire and cable and satelliteFederal Communications Commission to resolve the conflicts which had arisen between companies over the introduction of a nationwide analog television system in the U.S. The committee in March 1941 issued a technical standard for Quick Facts about: black and white A black-and-white photograph or slideblack and white television. In January 1950 the committee was reconstituted, this time to decide about color television, and in March 1953 it unanimously approved what is now called simply the NTSC color television standard. The updated standard retained full backwards compatibility with older black and white television sets. The standard has since been adopted by many other countries, for example most of Quick Facts about: the Americas North and South Americathe Americas and Quick Facts about: Japan A constitutional monarchy occupying the Japanese Archipelago; a world leader in electronics and automobile manufacture and ship buildingJapan.

  • A Preview of the Television Video and Audio – a Ready Reference for Engineers Course
    A Preview of the Television Video and Audio – a Ready Reference for Engineers Course About the Author Randy Hoffner is retired from ABC Broadcast Operations and Engineering West Coast, where he held the position of Manager of Technology and Quality Control. Prior to 2006, Hoffner spent a number of years at ABC BOE New York, where he worked on advanced television projects including HDTV and early film-to-720p video transfers, accomplished using data telecine transfer techniques. Before joining ABC, Hoffner spent 15 years at NBC, New York, where he worked on technology development projects, including early HDTV work, and held the positions of Director of Research and Development and Director of Future Technology. He also played a large role in the transition of the NBC Television Network and local NBC television stations to stereo broadcasting. He twice received the NBC Technical Excellence Award. Hoffner is a Fellow of SMPTE, and has served the Audio Engineering Society as Convention Chairman and Vice President, Eastern Region, US and Canada. He has authored a number of technical papers presented at SMPTE and AES conventions, and published in their respective Journals. For many years he has written a column, “Technology Corner”, for the trade publication TV Technology. Introduction The purpose of this course is to give the television engineer a solid grounding in the various aspects of video and audio for television, and to serve as a ready reference to the pertinent standards. This course provides an overview of video and audio for television, from the dawn of analog television broadcasting to today’s digital television transmission.
