question: How many affiliates carry the ABC network feed in 480i standard definition?
sentence: However, most of Hearst Television's 16 ABC-affiliated stations transmit the network's programming in 1080i HD, while 11 other affiliates owned by various companies carry the network feed in 480i standard definition either due to technical considerations for affiliates of other major networks that carry ABC programming on a digital subchannel or because a primary feed ABC affiliate has not yet upgraded their transmission equipment to allow content to be presented in HD.
