Effects of Poor Reception
Changes in signal reception from factors such as degrading antenna connections or changing weather conditions may gradually reduce the quality of analog TV. The nature of digital TV results in a perfectly decodable video initially, until the receiving equipment starts picking up interference that overpowers the desired signal or if the signal is too weak to decode. Some equipment will show a garbled picture with significant damage, while other devices may go directly from perfectly decodable video to no video at all or lock up. This phenomenon is known as the digital cliff effect.
For remote locations, distant channels that, as analog signals, were previously usable in a snowy and degraded state may, as digital signals, be perfectly decodable or may become completely unavailable. The use of higher frequencies will add to these problems, especially in cases where a clear line-of-sight from the receiving antenna to the transmitter is not available.
Famous quotes containing the words effects of, reception, effects and/or poor:
“Virtues are not emotions. Emotions are movements of appetite, virtues dispositions of appetite towards movement. Moreover emotions can be good or bad, reasonable or unreasonable; whereas virtues dispose us only to good. Emotions arise in the appetite and are brought into conformity with reason; virtues are effects of reason achieving themselves in reasonable movements of the appetites. Balanced emotions are virtues effect, not its substance.”
—Thomas Aquinas (c. 12251274)
“I gave a speech in Omaha. After the speech I went to a reception elsewhere in town. A sweet old lady came up to me, put her gloved hand in mine, and said, I hear you spoke here tonight. Oh, it was nothing, I replied modestly. Yes, the little old lady nodded, thats what I heard.”
—Gerald R. Ford (b. 1913)
“If one judges love according to the greatest part of the effects it produces, it would appear to resemble rather hatred than kindness.”
—François, Duc De La Rochefoucauld (16131680)
“Poor but happy is not a phrase invented by a poor person.”
—Mason Cooley (b. 1927)
