Modern Standards and Practices
In modern digital imaging systems and high-definition televisions, especially those that comply with SMPTE standards and practices, only square pixels are used for broadcast and display. However, some formats (ex., HDV, DVCPRO HD) use non-square pixels internally for image storage, as a way to reduce the amount of data that must be processed, thus limiting the necessary transfer rates and maintaining compatibility with existing interfaces.

Famous quotes containing the words modern, standards and/or practices:
“It was announced that the trouble was not “malignant.”... It was a typical triumph of modern science to find the only part of Randolph that was not malignant and remove it.”
—Evelyn Waugh (1903–1966)
“Measured by any standard known to science—by horse-power, calories, volts, mass in any shape,—the tension and vibration and volume and so-called progression of society were full a thousand times greater in 1900 than in 1800;Mthe force had doubled ten times over, and the speed, when measured by electrical standards as in telegraphy, approached infinity, and had annihilated both space and time. No law of material movement applied to it.”
—Henry Brooks Adams (1838–1918)
“Money made through dishonest practices will not last long.”
—Chinese proverb.
