This article focuses on the migration to advanced video coding. The two video coding methods AVC and VC-1 are better than MPEG-2 video compression. They can provide the same picture quality as MPEG-2 in about half the bandwidth. Broadcasters uses a kind of time division multiplexing to interleave signals using MPEG-2 coding with signals that can use advanced coding. This approach allows "legacy" receivers to ignore the signals with the advanced coding. The government will force the migration from analog to digital because it wants to reclaim the analog spectrum. There won't be any such forcing to move from MPEG-2 to AVC or VC-1.
