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]
In June 2016, EBU announced the "Advanced 1080p" format[11] which will include UHD Phase A features such as high-dynamic-range video (using PQ and HLG) at 10 and 12 bit color and BT.2020 color gamut, and optional HFR 100, 120/1.001 and 120 Hz; an advanced 1080p video stream can be encoded alongside baseline HDTV or UHDTV signal using Scalable HEVC. The ITU-T BT.2100 standard that includes Advanced 1080p video was subsequently published in July 2016.
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] 2ff7e9595c
