Television interference (TVI) is a particular case of electromagnetic interference which affects television reception. Many natural and man-made phenomena can disrupt the reception of television signals. These include naturally occurring and artificial spark discharges, and effects due to the operation of radio transmitters.
Analog television broadcasts display different effects due to different kinds of interference. Digital television reception generally gives a good quality picture until the interference is so large that it can no longer be eliminated by the error checking systems in the receiver, at which point the video display becomes pixelated, distorts, or goes blank.

Famous quotes containing the words television and/or interference:
“His [O.J. Simpson’s] supporters lined the freeway to cheer him on Friday and commentators talked about his tragedy. Did those people see the photographs of the crime scene and the great blackening pools of blood seeping into the sidewalk? Did battered women watch all this on television and realize more vividly than ever before that their lives were cheap and their pain inconsequential?”
—Anna Quindlen (b. 1952)
“Adolescent girls were fighting a mother’s interference because they wanted her to acknowledge their independence. Whatever resentment they had was not towards a mother’s excessive concern, or even excessive control, but towards her inability to see, and appreciate, their maturing identity.”
—Terri Apter (20th century)
