High Definition
ESPN launched its 720p high-definition simulcast, originally branded as ESPNHD, on March 20, 2001. All Bristol and L.A. Live studio shows, along with most live events on ESPN, use high definition. ESPN is one of the few networks with an all-digital infrastructure. Footage from non-HD sources is presented in a standard definition, 4:3 format with stylized pillarboxes. Pardon the Interruption and Around the Horn began airing in HD on September 27, 2010 with their move to the building housing the ABC News Washington bureau.
ESPN and all of ABC and Disney's cable networks use the 720p HD line standard because ABC executives proposed a progressive scan signal that resolves fluid and high-speed motion in sports better, particularly during slow-motion replays.
In 2011 ESPNHD began to downplay its distinct promotion logo in preparation for a shift of its standard definition-feed to letterboxed widescreen, which occurred on June 1, 2011.

Famous quotes containing the words high and/or definition:
“The duties which a police officer owes to the state are of a most exacting nature. No one is compelled to choose the profession of a police officer, but having chosen it, everyone is obliged to live up to the standard of its requirements. To join in that high enterprise means the surrender of much individual freedom.”
—Calvin Coolidge (1872–1933)
“... if, as women, we accept a philosophy of history that asserts that women are by definition assimilated into the male universal, that we can understand our past through a male lens—if we are unaware that women even have a history—we live our lives similarly unanchored, drifting in response to a veering wind of myth and bias.”
—Adrienne Rich (b. 1929)
