- Component video
- Component video is an analog video signal format that separates a video signal into three components: the luminance (brightness) component and two chrominance (color) components. These components are then transmitted separately over three cables or wires.
- In a component video signal, the three separate components of the video signal are usually carried on three RCA cables with different colors: red, green, and blue. This is commonly referred to as RGB component video. The green component carries the luminance information, while the red and blue components carry the color information.
- Component video is capable of transmitting high-quality video signals, particularly when compared to composite video, which transmits all video information on a single wire or pin. Component video is widely used in professional video production and is also found on many consumer electronics devices such as DVD players, gaming consoles, and HDTVs.
- However, component video is an analog video signal and is being phased out in favor of digital video standards like HDMI and DisplayPort, which offer higher quality and more advanced features, such as support for higher resolutions, 3D video, and multi-channel audio.
- Composite video
- Composite video is an analog video signal format that carries all video information on a single wire or pin. It combines the luminance (brightness) and chrominance (color) components of a video signal into a single signal that can be transmitted using a single cable.
- In a composite video signal, the luminance and chrominance components are combined by encoding them into a single signal using frequency modulation (FM). The resulting signal is then transmitted over a single cable, which can be a coaxial cable or an RCA cable.
- While composite video is a simple and widely used video signal format, it is not capable of transmitting high-quality video signals. Composite video signals are susceptible to interference and noise, which can result in distortion, color bleeding, and other types of image degradation. As a result, composite video has largely been replaced by newer digital video standards like HDMI and DisplayPort.

- HDR10
- HDR10 is a popular open standard for High Dynamic Range (HDR) technology used in consumer electronics, such as TVs, monitors, and media players. It was developed by the Consumer Technology Association (CTA) and is now widely adopted by manufacturers and content creators.
- HDR10 uses a 10-bit color depth, which means it can display over a billion colors, compared to the 16.7 million colors of a standard 8-bit display. It also has a peak brightness of 1,000 nits, which is significantly brighter than the 100-200 nits of a standard SDR (Standard Dynamic Range) display.
- To display HDR10 content, the display must be HDR10 compatible, which means it can receive and process the HDR10 metadata embedded in the content. This metadata provides information about the color and brightness levels of the content, allowing the display to adjust its settings to optimize the image quality.
- HDR10 is widely supported by streaming services, such as Netflix and Amazon Prime Video, and is also used for HDR content on Ultra HD Blu-ray discs. It is considered to be the minimum HDR standard for a good HDR experience, with other standards, such as Dolby Vision, offering even higher image quality.
- High Dynamic Range
- HDR
- It is a technology that allows for a greater range of color and brightness to be displayed on a screen or captured in a photograph.
- Traditional displays and cameras have a limited dynamic range, which means they can only show a certain range of colors and brightness levels. HDR technology, on the other hand, can capture or display a wider range of colors and brightness levels, resulting in more vibrant, lifelike images.
- HDR works by capturing or displaying more information about the brightness of a scene. This is achieved by capturing or displaying multiple exposures of the same scene, with each exposure capturing a different range of brightness levels. These multiple exposures are then combined to create an image with a wider dynamic range.
- There are different types of HDR, such as HDR10, Dolby Vision, and HLG (Hybrid Log-Gamma), each with their own specifications and capabilities. HDR is becoming increasingly popular in TVs, monitors, and cameras, and is now a standard feature in many high-end devices.
- High-bandwidth Digital Content Protection
- HDCP
- A digital copy protection used to protect digital content as it is transmitted over a digital interface, such as HDMI or DisplayPort. The purpose of HDCP is to prevent unauthorized copying of digital content, such as movies, TV shows, and video games, as it is transmitted from a source device, such as a Blu-ray player, to a display device, such as a TV or monitor.
- HDCP works by encrypting the digital content as it is transmitted from the source device to the display device, and only allowing the content to be played if the display device is authorized to receive it. The source device and display device must both support HDCP in order for the content to be transmitted and played securely. If the display device is not authorized, the content may not be played, or it may be played with degraded quality. This helps to prevent piracy and ensure that the rights of content owners are protected.
- High-Definition Multimedia Interface
- HDMI
- A digital interface used to transmit video and audio data from one device to another. It is commonly used to connect devices such as a DVD player, Blu-ray player, video game console, or a computer to a TV or monitor. HDMI supports high-definition video, including resolutions up to 4K, as well as multi-channel audio. This makes it an ideal interface for home theater systems, providing a high-quality audio and visual experience. HDMI cables also support copy protection technologies, such as HDCP, to prevent unauthorized copying of digital content.
- Hybrid Log-Gamma
- HLG
- HLG (Hybrid Log-Gamma) is another HDR (High Dynamic Range) technology that was jointly developed by the BBC and NHK, the public broadcasters of the United Kingdom and Japan, respectively. It was designed to provide a simpler solution for broadcasting HDR content that can be received by both HDR and non-HDR displays.
- HLG uses a combination of standard dynamic range (SDR) and HDR techniques to encode and display content. Specifically, it uses a logarithmic curve for brightness that allows the HDR content to be viewed on both SDR and HDR displays. This is because the logarithmic curve is compatible with the gamma curve used by SDR displays, while still providing more color and brightness information for HDR displays.
- The advantage of HLG is that it can be used for broadcasting HDR content, without requiring a separate broadcast stream for HDR and SDR displays. This is possible because HLG content is backwards compatible with SDR displays, which means that viewers with non-HDR displays can still view the content, albeit with a reduced dynamic range
- HLG is also used in some cameras and camcorders for capturing HDR content, as well as in some streaming services, such as the BBC iPlayer and YouTube. While HLG is not as widely used as HDR10 or Dolby Vision, it is gaining popularity as a simpler and more flexible solution for delivering HDR content.
- Multiple Stream Transport
- MST
- Multiple Stream Transport (MST) is a technology that allows a single DisplayPort output to be split into multiple displays. It enables the connection of multiple monitors to a single DisplayPort port on a computer or device, allowing for the creation of multi-monitor configurations. macOS computers currently do not support MST.
- Each monitor in the configuration is treated as a separate display, and the computer's operating system can configure the desktop and windows to span across multiple monitors. This allows for increased productivity and a larger display area, which can be useful in various applications, such as graphic design, video editing, and gaming.
- MST works by using the DisplayPort 1.2 standard and requires a device with MST support, such as a graphics card or a laptop with a built-in DisplayPort output. The device splits the DisplayPort signal into multiple streams, each of which is sent to a separate monitor.
- PCI Express
- PCIe
- PCI Express (PCIe) is a high-speed serial computer expansion bus standard that provides a connection between a computer and peripheral devices, such as graphics cards, sound cards, network adapters, and solid-state drives (SSDs).
- PCIe was designed as a replacement for the older parallel bus standards, such as Peripheral Component Interconnect (PCI) and AGP (Accelerated Graphics Port), and provides a number of advantages over these older standards, including:
- Increased bandwidth: PCIe provides a high-bandwidth, low-latency connection between the computer and peripheral devices, with bandwidths ranging from 250 MB/s to 128 GB/s.
- Scalability: PCIe provides a scalable bus architecture that allows for the addition of new devices and the expansion of existing devices.
- Improved reliability: PCIe uses a point-to-point connection between the computer and peripheral devices, reducing the potential for data errors and improving reliability.
- Improved power management: PCIe provides improved power management capabilities, allowing for the reduction of power consumption and heat generation in devices.
- PCIe has become the standard for connecting peripheral devices to computers and is widely used in both desktop and laptop computers. The latest version of PCIe is PCIe 6.0, which was introduced in 2021 and provides a bandwidth of up to 128 GB/s.
- RCA
- Radio Corporation of America
- RCA (Radio Corporation of America) is a type of connector used for analog audio and video signals. It is commonly known as the "phono connector" or "phono plug" and is recognizable by its distinctive design, which consists of a cylindrical plug with a small metal pin at the center and a surrounding metal ring.
- The RCA connector is often used for connecting analog audio and video devices such as DVD players, game consoles, and home theater systems to TVs, monitors, and speakers. RCA connectors are typically color-coded to help users distinguish between different types of connectors. For example, yellow RCA connectors are commonly used for composite video, while red and white RCA connectors are often used for stereo audio.
- While RCA connectors are still in use, they are gradually being replaced by newer digital standards like HDMI and DisplayPort, which offer higher quality video and audio signals.
- Standard Dynamic Range
- SDR
- SDR stands for Standard Dynamic Range. It is the traditional format used for displaying images on most TVs, computer monitors, and other display devices. SDR content typically has a limited range of colors and brightness levels, with a peak brightness of around 100-200 nits. SDR displays typically have a color depth of 8 bits, which means they can display up to 16.7 million colors.
- In SDR, the brightness levels of an image are represented on a linear scale, where each increase in brightness is represented by an equal step in the signal. This means that the signal levels for the brighter parts of an image are relatively close together, which can result in a loss of detail and contrast.
- In contrast, HDR (High Dynamic Range) technology, uses a non-linear scale that allows for a wider range of brightness levels and a greater number of colors to be displayed. This results in more lifelike and vibrant images.
- While SDR is still the most common format for displaying content, HDR technology is becoming increasingly popular, particularly for high-end devices and for streaming services that offer HDR content.

- Super Video
- Separate Video
- S-Video
- S-Video, also known as Separate Video or Super Video, is a video signal format that transmits video data as two separate signals: one for luminance (brightness) and one for chrominance (color information).
- In an S-Video signal, the luminance information is carried on one channel, usually a single pin or wire, while the chrominance information is carried on another channel. This separation of the two types of video information results in a higher-quality video signal compared to composite video, which carries all the video information on a single channel.
- S-Video was widely used in the late 1990s and early 2000s for connecting DVD players, gaming consoles, and other video devices to TVs and monitors. However, it has largely been replaced by newer digital video formats like HDMI and DisplayPort.
- Super Video Graphics Array
- SVGA
- SVGA (Super Video Graphics Array) is an extension of the VGA (Video Graphics Array) standard that was introduced by IBM in 1987. SVGA was developed in response to the need for higher resolution and better color quality in computer graphics and video displays.
- SVGA supports resolutions that are higher than the maximum 640x480 resolution supported by VGA. SVGA resolutions can range from 800x600 pixels to 1920x1080 pixels or higher, depending on the specific implementation. SVGA also supports a greater number of colors than VGA, typically up to 16 million colors, which allows for more detailed and realistic images.
- To support the higher resolutions and color depths of SVGA, the standard also requires higher bandwidth and faster signal transmission. To achieve this, SVGA typically uses a digital signal rather than the analog signal used by VGA. This allows for sharper, more accurate images with less interference and noise.
- SVGA uses the same 15-pin connector as VGA, and is backwards compatible with VGA displays, which means that a VGA display can display an SVGA signal, although at a lower resolution and color depth. SVGA cables can be used to connect a video source, such as a computer or a video card, to a display device, such as a monitor or a projector.
- While SVGA is an older video standard, it is still used in some applications, particularly in industries such as graphics design and gaming, where high-quality graphics and images are important. However, newer video standards such as HDMI and DisplayPort have largely replaced SVGA for most consumer and commercial applications, due to their support for even higher resolutions and refresh rates, as well as other advanced features.
