:So stations won't have to change their numbers (and can maintain the same numbers for their analog and digital broadcasts during the transition period, and can identify their main channel and sub channels with the same basic number).

Stations that are broadcasting in analog and digital cannot broadcast on the same frequency, thus the need for a "virtual channel." This has been confusing many viewers, but is a necessity for stations to maintain their "channel" number. In the future your receiver can be "told" to change channels based on demographic info. If a station chooses to have 99 channels to switch viewers to and from, they can all have the same virtual channel number.
