HD Backgrounds 1080p Biography
Any display device that advertises 1080p typically refers to the ability to accept 1080p signals in native resolution format, which means there are a true 1920 pixels in width and 1080 pixels in height, and the display is not overscanning, underscanning, or reinterpreting the signal to a lower resolution. The HD ready 1080p logo program, by DIGITALEUROPE, requires that certified TV sets support 1080p 24fps, 1080p 50fps, and 1080p 60fps formats, among other requirements, with fps meaning frames per second.
It is one of the more universally accepted video standards.[3]
For live broadcast applications, a high-definition progressive scan format operating at 1080p at 50 or 60 frames per second is currently being evaluated as a future standard for moving picture acquisition.[4][5] EBU has been endorsing 1080p50 as a future-proof production format because it improves resolution and requires no deinterlacing, allows broadcasting of standard 1080i25 and 720p50 signal alongside 1080p50 even in the current infrastructure and is compatible with DCI distribution formats.[6][7]
1080p50/p60 production format will require a whole new range of studio equipment including cameras, storage and editing systems,[8] and contribution links (such as Dual-link HD-SDI and 3G-SDI) as it has doubled the data rate of current 50 or 60 fields interlaced 1920×1080 from 1.485 Gbit/s to nominally 3 Gbit/s using uncompressed RGB encoding. Most current revisions of SMPTE 372M, SMPTE 424M and EBU Tech 3299 require YCbCr color space and 4:2:2 chroma subsampling for transmitting 1080p50 (nominally 2.08 Gbit/s) and 1080p60 signal.
Recent studies show that for digital broadcasts compressed with H.264/AVC, transmission bandwidth savings of interlaced video over fully progressive video are minimal even when using twice the frame rate, i.e., 1080p50 signal (50 progressive frames per second) actually produces the same bit rate as 1080i50 signal (25 interlaced frames or 50 sub-fields per second
In the United States, 1080p over-the-air broadcasts still do not exist as of January 2013; all major networks use either 720p60 or 1080i60 encoded with MPEG-2. However, satellite services (e.g., DirecTV, XstreamHD and Dish Network) utilize the 1080p/24-30 format with MPEG-4 AVC/H.264 encoding for pay-per-view movies that are downloaded in advance via satellite or on-demand via broadband. At this time, no pay service channel such as USA, HDNET, etc. nor premium movie channel such as HBO, etc., stream their services live to their distributors (MVPD) in this format because many MVPDs, especially DBS and cable, do not have sufficient bandwidth to provide the format streaming live to their subscribers without negatively impacting their current services. In addition is the high "cost" of using more bandwidth for one 1080p/24 channel than that necessary for a 1080i or even a 720p channel and for only those relatively few subscribers who have HDTV devices that can display 1080p/24 being an efficient use of their limited bandwidth.
For material that originates from a progressive scanned 24 frame/s source (such as film), MPEG-2 lets the video be coded as 1080p24, irrespective of the final output format. These progressively-coded frames are tagged with metadata (literally, fields of the PICTURE header) instructing a decoder how to perform a 3:2 pulldown to interlace them. While the formal output of the MPEG-2 decoding process from such stations is 1080i60, the actual content is coded as 1080p24 and can be viewed as such (using a process known as inverse telecine) since no information is lost even when the broadcaster performs the 3:2 pulldown.[13]
Blu-ray Disc
Blu-ray Discs are able to hold 1080p HD content, and most movies released on Blu-ray Disc produce a full 1080p HD picture when the player is connected to a 1080p HDTV via an HDMI cable. The Blu-ray Disc video specification allows encoding of 1080p23.976, 1080p24, 1080i50, and 1080i59.94. Generally this type of video runs at up to 40 megabits per second, compared to the 3.5 megabits per second for conventional standard definition broadcasts.[14]
Smartphones
Smartphones with 1080p FullHD display are available on the market since 2013. There are different brands that offers this resolution on their flagship phones' screens.
Internet content
Several websites, including YouTube, allow videos to be uploaded in the 1080p format. Digital distribution services also deliver 1080p content, such as movies available on Blu-ray Disc and/or from broadcast sources. This can include distribution services like peer-to-peer websites and public or private tracking networks.
Netflix will be offering SuperHD content in the US and other countries through select internet providers starting in 2013.[15]
Consumer televisions and projectors
As of 2012, most consumer televisions being sold provide 1080p inputs mainly via HDMI and support full high-def resolutions. 1080p resolution is available in all types of television, including plasma, LCD, DLP front and rear projection and LCD projection.
For displaying film-based 1080i60 signals, a scheme called 3:2 pulldown reversal (reverse telecine) is beginning to appear in some newer 1080p displays, which can produce a true 1080p quality image from film-based 1080i60 programs. Similarly, 25fps content broadcast at 1080i50 may be deinterlaced to 1080p content with no loss of quality or resolution.
The AV equipment manufacturing industry has adopted the term Full HD as the consumer-friendly marketing term to mean the set is a safe purchase because it can display all available HD resolutions up to 1080p. The term is misleading, however, because it does not guarantee the set is capable of rendering digital video at all frame rates encoded in source files with 1080 pixel vertical resolution. Most notably, a "Full HD" set is not guaranteed to support the 1080p24 format, leading to consumer confusion.[citation needed]
DigitalEurope (formerly EICTA) maintains the HD ready 1080p logo program that requires the certified TV sets to support 1080p24, 1080p50, and 1080p60, without overscan/underscan and picture distortion.
Computer monitors
Most widescreen cathode ray tube (CRT) and liquid crystal display (LCD) monitors can natively display 1080p content. For example, widescreen WUXGA monitors support 1920×1200 resolution, which can display a pixel for pixel reproduction of the 1080p (1920×1080) format. Additionally, many 23, 24, and 27-inch (690 mm) widescreen LCD monitors use 1920×1200 as their native resolution; 30 inch displays can display beyond 1080p at up to 2560×1600 (1600p). Many 27" monitors have native resolutions of 2560×1440 and hence operate at 1440p.
