Managing our DTV bandwidth

Two very good related articles by David Liroff and David Felland have now (finally) been posted to the web site of the public broadcasting newspaper, Current.  Liroff's article, DTV channel options: How much to mux?, was published on 12 Feb. 2007 and provides analysis about the trade-offs relating to how we manage our 19.39 mbps ATSC DTV streams.  Felland's article, We've got to clean up our act in high-definition, was published on 12 March and argues that we would gain capacity for additional services if all our HD programming offerings were produced in HD rather than upconverted film or analog formats.  Check them out.  --Dennis
