    "abstract": "There are many paths that can be taken during the transition from analog to digital television. Broadcasters must weigh the delivery of new services, such as high definition, multiplexed standard definition, pay television, and data broadcasting, versus budgetary and logistics constraints. Rather than jumping into a full-featured digital television (DTV) broadcast system, broadcasters may wish to consider the upgrade in phases. This paper discusses an upgrade path to delivery of new digital services that can be taken over four phases. At each phase, the broadcaster must build and install only a portion of the full DTV broadcast system; yet each phase also represents a milestone at which the broadcaster can deliver meaningful services.",

In his previous position as director of engineering for encoder products, he spearheaded the development and successful launch of the MediaView MV40 program encoder with DiviTrack statistical multiplexing. Earlier, he served as principal engineer and project engineer, roles that included defining the requirements and overall architecture of DiviCom's first generation MPEG encoder and multiplexer products. Magee joined DiviCom in 1993. Prior to that he spent four years as a system engineer with Compression Labs Inc. (CLI), Broadcast Products Division, now a division of General Instrument. While at CLI, he was a key contributer on the technical team that developed the video encoder for the Spectrum Saver system; the first compressed digital video system for broadcast applications. Magee earned his bachelor's degree in electrical engineering from the University of Texas at Austin.",
