  • Page 96: Introduction

    Introduction General The recent developments of high-capacity digital platforms turned Video On Demand (VOD) into a hot topic for service providers deploying a HFC network. VOD provides a choice of several program titles (e.g. movies), which the subscriber can control to give true VCR functionality. The subscriber is able to pause, rewind, fast forward, play or halt the service to resume later on where they left off.
  • Page 97 Introduction, Continued VOD Servers Video servers are powerful servers that are able to playout huge amounts of video data requests at the same time. They share a single copy of content among subscribers using the data stripping method. Data stripping splits the data into several blocks that are written to separate hard disks.
