It could be done with the current system, but would mean that all non-HD receivers would need to be replaced with MPEG4-capable equipment, at a tremendous cost. Now if Directv would stop making MPEG2-only receivers, that would be a start.
When the cost justifies it, I expect to see all new (SD or HD) installations to be SWM, with the H25 (or a newer replacement) being the standard. Directv plans released in 2008 indicated that there would be no more SD-only receivers but the economy tanked and there went that idea.
They could start with new SD being mpeg4 but that would limit the channels and would not be liked by the content providers.
However, nothing says that they couldn't take some of the bandwidth and make mpeg4 SD a dupe of the mpeg2 channel for those with hd. The bandwidth would be significantly less so they could squeeze a few SD channels into less than what an hd would take.
May not be a great idea but it is thinking out of the box.
