1000 level tv channels - XFinity

I recently noticed I now am receiving channels in the 1000 range. Not everything, but many channels are coming through at the basic level and the digital level (100s). Now many are also broadcast in the 1000 level. I don't notice a difference in quality. Is there a reason for this recent addition?
