COURSE # TOO-344
MODERN CABLE TELEVISION, CATV, TECHNOLOGIES AND EMERGING SERVICES
A comprehensive, detailed introduction and overview of the technologies now serving the Cable TV industry.
Cable television, conceived originally as an alternative transmission method for broadcast programming to homes, is undergoing dramatic changes. Supported by the latest advances in technology and benefiting from the recent regulatory changes, it joins the telecommunications industry in offering convergence of video, voice and data services. Growing competitive pressures within the industry necessitate continual improvement of the performance and reliability of services, leading to new system strategies incorporating latest technologies. Fiber optic links are deployed routinely offering several key advantages, including reduction in the number of cascaded amplifiers, yielding lower cost and higher reliability, along with increased channel capabilities due to reduced cumulative noise and distortions. The emerging digital transmission technology will provide the opportunity for Cable TV operators to deliver high definition (HDTV) channels, and /or to add many more channels of NTSC quality.
This course reviews CATV technologies used in traditional coax "copper" CATV systems and presents detailed system and hardware design considerations from the headend to the subscriber. Examination of fiber optic links in new architectures such as HFC, hybrid fiber coax, is followed by system analyses of analog fiber optic links utilizing Lotus spreadsheets, which will be made available to the participants. Additionally, this course examines digital video and/or data transmission over state-or-the-art systems, including detailed descriptions of analog video signal digitization and compression (MPEG). System performance analyses of digital links are presented demonstrating the relationship between bit error rate (BER) and the carrier to noise (C/N) ratio, followed by an overview of the new test methods employed in the characterization of system performance.

About the Instructors
Jack Koscinski has over 25 years of experience in Cable TV and fiber optic industries. He is the Engineering Manager at LDI (Laser Diode Inc.) where he is intimately involved in the system and hardware design of analog and high speed digital fiber optic transmission products for SONET. His previous experience includes design and management positions at Warner Amex Cable (now Time Warner), Magnavox CATV (now Philips Broadband), and Blonder-Tongue Labs, where he was responsible for hardware design of headend products, including video modulators and demodulators, broadband coaxial amplifiers, and set top converter products. While at Warner Amex, he participated in one of the first (1983) cable TV fiber optic implementations in Dallas, Texas, where a multichannel fiber optic link was installed to provide a backup for a microwave headend to hub connection.
Mr. Koscinski received his BSEE and MSEE degrees from Monmouth College, and MBA from Rider College. He has several technical publications on the subjects of CATV, Optical Transmission and Automated Testing.
