1080p video signals are supported by ATSC standards in the United States and DVB standards in Europe. Applications of the 1080p standard include television broadcasts, Blu-ray Discs, smartphones, Internet content such as YouTube videos and Netflix TV shows and movies, consumer-grade televisions and projectors, computer monitors and video game consoles. Small camcorders, smartphones and digital cameras can capture still and moving images in 1080p resolution.

Any screen 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 over-scanning, under-scanning, or reinterpreting the signal to a lower resolution.[citation needed] The HD ready 1080p logo program, by DIGITALEUROPE, requires that certified TV sets support 1080p 24 fps, 1080p 25 fps, 1080p 50 fps, and 1080p 60 fps formats, among other requirements, with fps meaning frames per second. 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. Although 24 frames per second is used for shooting the movies.[2][3][needs update] EBU has been endorsing 1080p50 as a future-proof production format because it improves resolution and requires no deinterlacing, allows broadcasting of standard 1080i50 and 720p50 signal alongside 1080p50 even in the current infrastructure and is compatible with DCI distribution formats.[4][5][needs update]
1080p50/p60 production format requires a whole new range of studio equipment including cameras, storage and editing systems,[6] 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 1920x1080 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. Studies from 2009 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).[4][5][7]
EBU requires that legacy MPEG-4 AVC decoders should avoid crashing in the presence of SVC or 1080p50 (and higher resolution) packets.[9] SVC enables forward compatibility with 1080p50 and 1080p60 broadcasting for older MPEG-4 AVC receivers, so they will only recognize baseline SVC stream coded at a lower resolution or frame rate (such as 720p60 or 1080i60) and will gracefully ignore additional packets, while newer hardware will be able to decode full-resolution signal (such as 1080p60).
In the United States, 1080p over-the-air broadcasts are currently available in select stations in some cities in the US via ATSC 3.0 multiplex stations where as ATSC 3.0 is currently rolling out throughout the U.S. The majority of the stations that broadcast at 1080p are CBS and NBC stations and affiliates. All other stations do not broadcast at 1080p and usually broadcast at 720p60 (including when simulcasting in ATSC 3.0) or 1080i60 (outside of ATSC 3.0) encoded with MPEG-2. There is also technical restrictions with ATSC 3.0 multiplex stations that prevent stations from airing at 1080p. While converting to ATSC 3.0 is voluntary by TV Stations, there is no word when any of the major networks will consider airing at 1080p in the foreseeable future on a national scale, although they are required to broadcast ATSC signals for at least five years thereafter. 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.[citation needed]
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 30 to 40 megabits per second, compared to the 3.5 megabits per second for conventional standard definition broadcasts.[14]
Several websites, including YouTube, allow videos to be uploaded in the 1080p format. YouTube streams 1080p content at approximately 4 megabits per second[16] compared to Blu-ray's 30 to 40 megabits per second. Digital distribution services like Hulu and HBO Max also deliver 1080p content, such as movies available on Blu-ray Disc or from broadcast sources. This can include distribution services like peer-to-peer websites and public or private tracking networks. Netflix has been offering high quality 1080p content in the US and other countries through select internet providers since 2013.[17]
As of 2012, most consumer televisions being sold provide 1080p inputs, mainly via HDMI, and support full high-definition 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.
AV equipment manufacturers have adopted the term Full HD to mean a set 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 1920 X 1080 pixel resolution. Most notably, a "Full HD" set is not guaranteed to support the 1080p24 format, leading to consumer confusion.[18][19][20] 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.
PS3 is available today at retailers nationwide in two configurations for consumers. One features a 20-GB hard disk drive (HDD) and carries a suggested retail price of $499, while the second features a 60-GB HDD and built in Wi-Fi adapter and multiple memory card slots for $599. At the heart of PS3 is the Cell Broadband Engine, one of the most-advanced computer processors in the world, that enables massive floating point calculation, and Blu-ray Disc (BD) drive, providing a true High Definition (1080p)* next-generation gaming and movie experience in the home, as well as up to 50 GB of data capacity for video game developers to store content - five times the capacity of DVD.
But the technological advances don't just stop in the system itself, they are also found in the controller. The PS3 system's innovative, new SIXAXIS wireless controller allows gamers to physically turn, twist, and bank their controllers to command the on-screen action. Every PS3 also comes equipped with an HDMI output for the best connection possible to high-definition displays, supporting Full-HD resolution up to 1080p for both games and movies*. Built-in network capability means that all PS3 owners can enjoy online game play and services, such as Web browsing through the PlayStation Network and downloadable content through the PlayStation Store, immediately. Additionally, the first half million PS3 systems shipped in North America will include one of this summer's biggest blockbuster hits from Sony Pictures Home Entertainment, "Talladega Nights: The Ballad of Ricky Bobby," starring Will Ferrell, on high-definition BD format.
However, there are also lots of illegitimate streaming sites that host copyrighted material without legal permission. You can watch movies for free using these websites, but you may be breaking the law as it is considered piracy in many countries.
Most new movies and Peacock Originals are paywalled, but there are also lots of great movies you can stream without paying, from cult classics to contemporary comedies. Free movies are marked by the absence of a purple feather. 2ff7e9595c
