A gold compact disc is one in which gold is utilized in place of the high-purity aluminium or silver commonly used as the reflective coating on ordinary CDs and CD-Rs respectively. Gold disks are available as both CDs and CD-Rs as well, and are compatible with standard players and recorders.
A key difference between 1080i and 1080p is how the lines of resolution are displayed. Both offer 1920x1080 pixels, but the display method is different. In 1080p, the "p" stands for progressive scan. Each frame is drawn line by line, from top to bottom, creating a complete image in a single pass.
To convert 24 frame/s film to 29.97 frame/s (presented as 59.94 interlaced fields per second) NTSC, a process called "3:2 pulldown" is used, in which every other film frame is duplicated across an additional interlaced field to achieve a framerate of 23.976 (the audio is slowed imperceptibly from the 24 frame/s source to match). This produces ...
Interlaced scanning: display of odd (green) and even (red) scanlines, and line return blanking periods (dotted) For analog NTSC, there are a total of 525 scanning lines per frame of which originally 483 lines were visible (241.5 visible lines per field + 21 lines of vertical blanking per field = 483 + 42 = 525 lines per frame) and later 480 (240 complete lines per field).
On smaller CRT monitors (up to about 15 in or 38 cm), few people notice any discomfort between 60–72 Hz. On larger CRT monitors (17 in or 43 cm or larger), most people experience mild discomfort unless the refresh is set to 72 Hz or higher. A rate of 100 Hz is comfortable at almost any size. However, this does not apply to LCD monitors.
The 576 identifies a vertical resolution of 576 lines, and the i identifies it as an interlaced resolution. [1] The field rate , which is 50 Hz , is sometimes included when identifying the video mode, i.e. 576i50 ; another notation, endorsed by both the International Telecommunication Union in BT.601 [ 2 ] and SMPTE in SMPTE 259M , includes the ...
A GIF from HandBrake, demonstrating the difference between deinterlaced and interlaced images [8] One of the most important factors in analog television is signal bandwidth, measured in megahertz. The greater the bandwidth, the more expensive and complex the entire production and broadcasting chain.
High 4:2:2 Profile (Hi422P): Primarily targeting professional applications that use interlaced video, this profile builds on top of the High 10 Profile, adding support for the 4:2:2 chroma sampling format while using up to 10 bits per sample of decoded picture precision.
