The method of scanning an entire TV image line-by-line. Pro: Does not have the limitations of interlaced scanning such as artifacting. Con: Requires more bandwidth than interlaced scanning, so a larger and more detailed image isn't feasible.
A video scanning system that shows all the lines of a video-frame at each pass. The refresh rate is 60 times per second, double than Interlaced Scanning.
Some HD televisions use the “progressive” method of scanning, in which the whole picture is transmitted and presented on the screen in one pass. The resulting image is thus remarkably free of flicker and motion artefacts, appearing more “life-like”. Some display types, such as LCD, plasma and DLP are inherently of the progressive scan type, while CRT’s may be scanned progressively (as in computer monitors) or interlaced. SIP: Acronym for "Program and ystem nformation rotocol", an ATSC DTV specification that enables a DTV receiver to locate the various programs sent in the DTV channel, to identify the program information and to create on-screen electronic program guides and content advisories.
The process of re-assembling a picture from a video signals, all the horizontal scan lines are scanned on the screen at one time.
Scanning with Interlace Ratio equal to unity. Synonyms: Non-Interlaced Scanning; Sequential Scanning
The process of scanning a single image ("frame") of a moving picture sequence progressively from top to bottom, producing a scanned image containing all of the horizontal lines used in the scanning process. Used in PC monitors and some advanced television systems. See also Interlace Scanning.
Progressive scanning is used by some HDTVs. Progressive scanning offers rather smooth picture as 720 or 1080 horizontal lines are scanned progressively or in succession in a vertical frame that is repeated 30 times a second. Some displays, for example LCD and plasma use progressive scanning method, while CRTs may use progressive (e.g. in computer monitors) or interlaced scanning method.
A method of creating an image on a video monitor by displaying the scanning lines sequentially from top to bottom. Contrast with "interlaced scanning."
A system of video scanning where lines of a picture are displayed consecutively (unlike interlaced).
Each frame of a video image is scanned complete, from top to bottom, not interlaced. For example, 480p means that each image frame is made of 480 horizontal lines drawn vertically. Computer images are all progressively scanned. Requires more bandwidth (twice as much vertical information) and a faster horizontal scan frequency than interlaced images of the same resolution.
A format for displaying a video image in which each frame of a video is scanned complete, from top to bottom, not interlaced. Because the entire frame is displayed at one time (as opposed to Interlaced Scanning), better image quality is displayed and no content is lost.
Sequential scanning, or non-interlaced video scanning. A television scanning system in which each scanning line follows its predecessor in a progressive fashion, rather than skipping intermediate lines to be filled in by the next field.
In progressive scanning, typically used by VGA computer monitors, all the horizontal scan lines are 'painted' on the screen at one time. Adopted DTV formats include both interlaced and progressive broadcast and display methods.
The opposite of Interlaced scanning. Shows each scanning line in sequence, for a more seamless, more film-like image.
The ability of most computer monitors and high resolution sets to display all the lines of a picture at the same time. When talking about resolution, this method is indicated by indicated by "p" after the number of lines, as in "720p".
A method of displaying images from a video signal on a television screen. With progressive scanning, the vertical lines on the screen are filled in sequentially, rather than in two passes as with interlaced scanning. Also see " interlaced scanning".
Each frame of a video image is scanned complete, from top to bottom, not interlaced. For example, 480p means that each image frame is made of 480 horizontal lines drawn vertically. It requires more bandwidth (twice as much vertical information) and a faster horizontal scan frequency than interlaced images of the same resolution. Computer images are all progressively scanned.
