ESPNHD

ESPNHD, launched on March 30, 2003, is a 720p high-definition simulcast of ESPN. ESPNHD (along with sister networks ESPN2 HD,ESPNU HD, ABC HD, Disney Channel HD, ABC Family HD, and Disney XD HD) uses the 720p HD line standard because the ABCexecutives proposed a progressive 'p' signal that resolves fluid and high speed motion in sports better, particularly during slow motion replays.
