Sony HDVS

HDVSHigh Definition Video System
The Sony HDVS system was presented at an international meeting of television engineers in Algiers, April 1981 and Japan's NHK presented its analog HDTV system at a Swiss conference in 1983.
Sony HDVS is a range of high-definition video equipment developed in the 1980s to support an early analog high-definition television system thought to be the broadcast television systems that would be in use today.

Multiple sub-Nyquist sampling encoding

MUSEHi-Vision1035i30
Modern HD specifications date to the early 1980s, when Japanese engineers developed the HighVision 1,125-line interlaced TV standard (also called MUSE) that ran at 60 frames per second.
MUSE (Multiple sub-Nyquist sampling encoding), was an analog high-definition television standard, using dot-interlacing and digital video compression to deliver 1125-line high definition video signals to the home.

1080p

full HD1080p301080p HD
Often, the rate is inferred from the context, usually assumed to be either 50 Hz (Europe) or 60 Hz (USA), except for 1080p, which denotes 1080p24, 1080p25, and 1080p30, but also 1080p50 and 1080p60.
1080p (1920×1080 px; also known as Full HD or FHD and BT.709) is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the p stands for progressive scan, i.e. non-interlaced.

HD DVD

The number of lines in the vertical display resolution. High-definition television (HDTV) resolution is 1,080 or 720 lines. In contrast, regular digital television (DTV) is 480 lines (upon which NTSC is based, 480 visible scanlines out of 525) or 576 lines (upon which PAL/SECAM are based, 576 visible scanlines out of 625). However, since HD is broadcast digitally, its introduction sometimes coincides with the introduction of DTV. Additionally, current DVD quality is not high-definition, although the high-definition disc systems Blu-ray Disc and the HD DVD are.
HD DVD (short for High Definition Digital Versatile Disc) is a discontinued high-density optical disc format for storing data and playback of high-definition video.

Film look

1080i

Non-cinematic HDTV video recordings are recorded in either the 720p or the 1080i format.
1080i (also known as Full HD or BT.709) is an abbreviation referring to a combination of frame resolution and scan type, used in high-definition television (HDTV) and high-definition video.

Digital cinema

In late 1949, official French transmissions finally began with 819.
The country began broadcasting wideband analog high-definition video signals in the late 1980s using an interlaced resolution of 1035 or 1080-lines active (1035i) or 1125-lines total supported by the Sony HDVS line of equipment.

A number of online video streaming/on demand and digital download services offer HD video, among them YouTube, Vimeo, Hulu, Amazon Video On Demand, Netflix Watch Instantly, and others.
In 2007, Vimeo became the first video sharing site to support high-definition video and has since launched a number of products that enable quality video creation at scale, most recently with the launch of Vimeo Stock in fall of 2018.

However, since HD is broadcast digitally, its introduction sometimes coincides with the introduction of DTV. Additionally, current DVD quality is not high-definition, although the high-definition disc systems Blu-ray Disc and the HD DVD are.
The proposal involved compressing high-definition video onto dual-layer standard DVD-9 discs.

One exception to this was the 1986 National Film Board of Canada short film Momentum, which briefly experimented with both filming and projecting at 48 frame/s, in a process known as IMAX HD.
In January 2010, the NFB added high-definition and 3D films to the over 1400 productions available for viewing online.

Video scaler

upscaledupscalingupconverted
Due to heavy compression, the image detail produced by these formats are far below that of broadcast HD, and often even inferior to DVD-Video (3-9 Mbit/s MP2) upscaled to the same image size.
A video scaler is a system which converts video signals from one display resolution to another; typically, scalers are used to convert a signal from a lower resolution (such as 480p standard definition) to a higher resolution (such as 1080i high definition), a process known as "upconversion" or "upscaling" (by contrast, converting from high to low resolution is known as "downconversion" or "downscaling").

ATSC standards

ATSCdigitaldigital facilities
The FCC process, led by the Advanced Television Systems Committee (ATSC) adopted a range of standards from interlaced 1,080-line video (a technical descendant of the original analog NHK 1125/30 Hz system) with a maximum frame rate of 30 Hz, (60 fields per second) and 720-line video, progressively scanned, with a maximum frame rate of 60 Hz.In the end, however, the DVB standard of resolutions (1080, 720, 480) and respective frame rates (24, 25, 30) were adopted in conjunction with the Europeans that were also involved in the same standardization process.

The Wii U is the first Nintendo console to support HD graphics.

MPEG-4

MPEG44MP4
Companies promoting MPEG-4 compatibility do not always clearly state which "part" level compatibility they are referring to. The key parts to be aware of are MPEG-4 Part 2 (including Advanced Simple Profile, used by codecs such as DivX, Xvid, Nero Digital and 3ivx and by QuickTime 6) and MPEG-4 part 10 (MPEG-4 AVC/H.264 or Advanced Video Coding, used by the x264 encoder, Nero Digital AVC, QuickTime 7, and high-definition video media like Blu-ray Disc).

VP8

At least in the implementation (from August 2011), VP8 is comparatively badly adapted to high resolutions (HD).

Betacam

Digital BetacamDigiBetaMPEG IMX
Older (pre-HDTV) recordings on video tape such as Betacam SP are often either in the form 480i60 or 576i50.
HDCAM, introduced in 1997, was the first HD format available in Betacam form-factor, using an 8-bit DCT compressed 3:1:1 recording, in 1080i-compatible downsampled resolution of 1440×1080, and adding 24p and 23.976 PsF modes to later models.

HDMI

Micro HDMIHDMI 1.4micro-HDMI
Most computers are capable of HD or higher resolutions over VGA, DVI, HDMI and/or DisplayPort. Both the PlayStation 3 game console and Xbox 360 can output native 1080p through HDMI or component cables, but the systems have few games which appear in 1080p; most games only run natively at 720p or less, but can be upscaled to 1080p.
In addition to the features in common with HDMI (such as HDCP encrypted uncompressed high-definition video and eight-channel surround sound), MHL also adds the provision of power charging for the mobile device while in use, and also enables the TV remote to control it. Although support for these additional features requires connection to an MHL-enabled HDMI port, power charging can also be provided when using active MHL to HDMI adapters (connected to standard HDMI ports), provided there is a separate power connection to the adapter.

In contrast, regular digital television (DTV) is 480 lines (upon which NTSC is based, 480 visible scanlines out of 525) or 576 lines (upon which PAL/SECAM are based, 576 visible scanlines out of 625). However, since HD is broadcast digitally, its introduction sometimes coincides with the introduction of DTV. Additionally, current DVD quality is not high-definition, although the high-definition disc systems Blu-ray Disc and the HD DVD are.
With digital terrestrial television (DTT) broadcasting, the range of formats can be broadly divided into two categories: high definition television (HDTV) for the transmission of high-definition video and standard-definition television (SDTV).

Microsoft's Xbox Live service includes the Xbox Live Arcade and Xbox Live Marketplace, featuring digital distribution of classic and original titles. These include arcade classics, original titles, and games originally released on other consoles. The Xbox Live Marketplace also includes many different hit movies and trailers in high definition, and is accessible with an Xbox Live Free Membership. There is also an "Indie Games" section where small-time developers can buy a license and release their own games onto the marketplace. Such is their volume, these games are not viewed by Microsoft as standard and are instead rated by the public.

Wii

The Wii can output up to 480p (enhanced-definition) over component, which while not HD, is very useful for HDTVs as it avoids de-interlacing artifacts.
The Wii U features a controller with an embedded touch screen and output 1080p high-definition graphics; it is fully backward-compatible with Wii games and peripherals for the Wii.
