Preface From headend through home, the technologies associated with delivering high bandwidth services to meet end users’ quality expectations evolve continuously. Compression techniques for video services are migrating from MPEG-2 to MPEG-4 and beyond. The Metro/Core network is transitioning from legacy SONET/SDH to next generation packet technology designed to transport voice, video, and data over an Application-Aware IP backbone. All of this while the Access Network, including the “last mile,” as we know it today is being extended throughout the consumer’s home or business with myriad in-home or premises distribution technologies. Reliable delivery of triple-play services all of the way to the consumer’s television or PC, however, remains key for service provider success. JDSU offers you this guide as a starting point to understand best practices for test, measurement, and quality assurance for technologies and services that are indeed constantly changing. It represents the first in a series of resources that will assist the service provider in gaining an understanding of the challenges and associated solutions available to develop test and service assurance plans for triple-play networks. Future publications will address advances in technology (MPEG-4 and H.264 details, for example) and services (Interactive TV) and associated test and measurement requirements. We invite you to contact JDSU at tripleplay@jdsu.com or call your local sales representative for further information about the concepts, technologies, and solutions presented in The Guide. vii
