Exceptional Image Quality Only Canon Can Deliver Exceptional Image Quality… Definitive Control… Professional Functionality. Canon’s XL H1S and XL H1A High Definition HDV, shoulder- mount camcorders stand out in the most demanding environ- ments. Decades of Canon leadership in the design and manufacture of cameras and lenses for broadcast and still photography ensure optical excellence and superb image quality, while Canon’s technical prowess delivers industry standard connectivity and an extraordinary level of custom control. Exceptional Image Quality Only Canon Can Deliver Genuine Canon 20x HD Video Zoom Lens III Canon Interchangeable XL Lens Mount The XL H1S and XL H1A feature the XL mount system that offers the added range and flexibility of using optional interchangeable lenses, including the wide- angle Canon 6x HD Video Zoom XL 3.4–20.4mm L lens (35mm equivalent 24.5–147mm), ideal for applications requiring a wider field-of-view. This L-series lens captures in Full HD clarity and incorporates all of Canon’s leg- endary optical superiority. The XL lens mount also enables the use of the Extender XL 1.6x, which increases the focal length by 1.6x and the EF Adapter XL, which enables users to attach a wide array of Canon photographic EF Extender lenses (only L-series is XL 1.6x EF Adapter XL recommended)—for specialized image capture. The XL H1S and XL H1A have all the advantages of Canon’s proven leadership in optical technology and optics drive HD SuperRange Optical Image Stabilizer image quality. The interchangeable Genuine Canon 20x HD Video Zoom Lens III (35mm Steady images are ensured with Canon’s equivalent 38.9–778mm) is a new high-performance L-series lens, specifically designed for HD Optical Image Stabilizer.

Professional Functionality for Today’s Production Environments Flexible Audio Control HD-SDI, Genlock and Time Code Connection Terminals (XL H1S only) The Canon XL H1S is ready for any professional application with HD-SDI, Genlock and Time Code Connections (BNC). SDI outputs conform to industry standards HD-SDI (SMPTE 299M) or SD-SDI (SMPTE 272M. The XL H1S includes embedded audio and time code. The HD-SDI output provides an uncom- pressed 1.485 Gbps 60i signal at 1920 x 1080 resolution with 4:2:2 color sampling. Because a single industry standard connection carries video, audio and SMPTE (LTC) Time Code, cabling com- plexity is significantly reduced. This enables longer cable runs, improves the operator’s mobility, and simplifies the cabling process. Genlock input enables synchronization of a multi-camera, live- switched production environment in the studio or on location. When shooting HD, it can accept either an SD (blackburst) or HD (tri-level) sync signal. A separate SMPTE Time Code Input and Output The XL H1S and XL H1A allow for advanced control over all aspects of audio during recording.

  • Strategic Maneuvering and Mass-Market Dynamics: the Triumph of VHS Over Beta
    Strategic Maneuvering and Mass-Market Dynamics: The Triumph of VHS Over Beta Michael A. Cusumano, Yiorgos Mylonadis, and Richard S. Rosenbloom Draft: March 25, 1991 WP# BPS-3266-91 ABSTRACT This article deals with the diffusion and standardization rivalry between two similar but incompatible formats for home VCRs (video- cassette recorders): the Betamax, introduced in 1975 by the Sony Corporation, and the VHS (Video Home System), introduced in 1976 by the Victor Company of Japan (Japan Victor or JVC) and then supported by JVC's parent company, Matsushita Electric, as well as the majority of other distributors in Japan, the United States, and Europe. Despite being first to the home market with a viable product, accounting for the majority of VCR production during 1975-1977, and enjoying steadily increasing sales until 1985, the Beta format fell behind theVHS in market share during 1978 and declined thereafter. By the end of the 1980s, Sony and its partners had ceased producing Beta models. This study analyzes the key events and actions that make up the history of this rivalry while examining the context -- a mass consumer market with a dynamic standardization process subject to "bandwagon" effects that took years to unfold and were largely shaped by the strategic maneuvering of the VHS producers. INTRODUCTION The emergence of a new large-scale industry (or segment of one) poses daunting strategic challenges to innovators and potential entrants alike. Long-term competitive positions may be shaped by the initial moves made by rivals, especially in the development of markets subject to standardization contests and dynamic "bandwagon" effects among users or within channels of distribution.

FOREWORD This book on VCR Servicing & Troubleshooting has been written by Shri V. Appakutty, a well known author of books on subjects of interest to video enthusiasts in a splendid manner. This book is easily readable and understandable by any one who has got interest in electronics. The VHS VCRs have flooded the Indian market and even Indian companies have started manufacturing VHS VCRs. In this book, the chapter on Troubleshooting will be of immense use to the servicing technicians. The effort of Shri V. Appakutty is commendable. I wish he brings out many more books for the benefit of video users. (K.C.C. Raja) Engineer in chief M.Sc.; C.Eng.; F.I.E.; F.I.E.T.E.; Doordarshan F.B.S.; A.M.I.E.R.E.
