The Role of a DTV Edge Server in Support of Data Broadcasting Applications
Abstract
With a bandwidth of 19.4 Mbps, the DTV channel has the potential to be an extremely valuable broadcast resource, yet television's traditional use of distributing video programs to viewers does not sufficiently exploit this capability. In order to realize DTV's true potential, the DTV channel should be considered more generically as a network resource, and the potential services and applications explored. In this paper, we present a basic Data Broadcast application for automatically augmenting video news programs with auxiliary information, and then discuss a general architecture of creating a broadcast edge server. Like its Internet counterpart, the broadcast edge server provides an edge located storage system for efficiently delivering applications and content to DTV receivers while allowing the real-time pass-thru of Internet and Broadcast content as required.
