Football overflow feeds
Many times on football Saturdays, the Big Ten Network produces multiple games that air at the same time. The network designates one game as its national game, which is shown on the main channel on satellite systems. The remaining games air on the main channel in the local markets and on the extra football game channels in the remaining markets. Most cable systems inside the Big Ten's eight states offer these Big Ten Network extra football game channels or "out-of-market" feeds. All the extra football game channel feeds are available nationally on DirecTV and Dish Network; and regionally on AT&T U-verse, many Comcast systems, and several other cable systems. Some systems offer only some of the extra football game channel feeds. Other systems don't offer any overflow feeds at all. DirecTV and Dish Network offer all games in HD. However, some cable systems offer only the game on the main channel in HD and the rest in SD.
