Hdmi Vs Component 720p 21


Our 4 ch H-4ADHD-QAM-IPLL worked on the Comcast system as an inserted channel.We have simple GUI instructions on how to set it up, we can percent it everything before the shipping, so it would be just plugged and play.We have also other similar modulators for 1,2,8 and 12channels.We have great flexible products and technical supportPlease check those units for your reference2 HDMI Modulator -hdmi-ypbpr-hd-digital-tv-modulator-qam-atsc-dvb-t-8230.html8 HDMI/SDI modulator -channel-hdmi-and-sdi-clear-catv-rf-modulator-qam-8230.html12 HDMI modulator -rf-modulator-hdmi-multiplexer.html/37




hdmi vs component 720p 21



The next two photos demonstrate how the output is slightly magnified on my TV in the current pre-release compared with the official release. Notice the relative position of the circles in the background. In both shots the output is HDMI 720p 50Hz.


The signals carried by SCART include both composite and RGB (with composite synchronisation) video, stereo audio input/output and digital signalling. The standard was extended at the end of the 1980s to support the new S-Video signals. A TV can be woken from standby mode and automatically switch to the appropriate AV channel when the SCART attached device is switched on. SCART was also used for high definition signals such as 720p, 1080i, 1080p with YPbPr connection by some manufacturers, but this usage is scarce due to the advent of HDMI.

The standard was extended at the end of the 1980s to support the new S-Video signals. A TV can be awakened from standby mode, and it can automatically switch to appropriate AV channel, when the device attached to it through a SCART connector is turned on. SCART connection was also used for high definition signals like 720p, 1080i, 1080p with YPbPr connection by some manufacturers, but to the present day this connection is very scarce due to the advent of HDMI.


Damaging pins 7, 11 or 15 may result in yellow, purple or blue/green images, due to the missing blue, green or red components respectively. When using S-video, damaging pin 7 or 15 may result in black-white images due to the missing chroma component ("down" and "up" respectively). Similarly, damaging pins 7 and 15 (PB and PR) while leaving pin 11 (Y) undamaged may result in black-white images when using YPBPR. Damaging more than one of these pins may result in combined effects.


There is no switching signal to indicate S-Video. Some TVs can auto-detect the presence of the S-Video signal but more commonly the S-Video input needs to be manually selected. The same for the rare component YPbPr, which is in many cases implemented over a composite or RGB SCART.


SCART connection was also used, in limited cases, as a high definition connection by using an YPbPr connection over scart by some television and audio video equipment (set top boxes, DVD players, Blu-ray players, etc.) manufacturers. By using an YPbPr connection, SCART could be used for high definition signals, like 720i, 720p, 1080i, 1080p. Some manufacturers were using as Y the video composite connection, while others were using the green connection as Y. With the advent of HDMI, and because the connection was not standardized (as was S-video) and limited only to a certain manufacturer, devices supporting high definition channels over SCART with YPbPr connection became scarce, if not extinct. In many cases, it was implemented over a RGB SCART or CVBS SCART and the YPbPr mode of SCART was manually switched. YPbPr became used as an independent connection, and SCART was left only for standard definition content.


The GameCube, Wii, Neo-Geo, Dreamcast, PlayStation, PlayStation 2, PlayStation 3, Xbox and Xbox 360 can output RGB, component video, S-Video, or composite video. These consoles come with the standard composite video connector, but the manufacturers and third parties sell connectors for component video hookup and for RGB SCART hookup. Where the Nintendo GameCube and Xbox automatically switch to the proper mode, the PlayStation 2 must be told via a selection in the system menu whether it is to use YPBPR or RGB video. RGB is only available on PAL region GameCube and Wii consoles, while S-Video is only available on NTSC consoles.[11]


As it was designed to carry analog standard-definition content, the use of SCART has declined with the introduction of new digital standards such as HDMI and DisplayPort, which can carry high-definition content and multichannel audio, though it remains commonly used. HDMI-CEC is derived from SCART's AV.link.[citation needed] However, SCART Connection can also support higher definition signals like 480p, 720p, 1080i, 1080p, if the SCART connection of a device is designed to support YPbPr connection, but this configuration is rare. The same for multichannel audio, but even this configuration remains rare, as it is not standardized.


Component video is an analog video signal that has been split into two or more component channels. In popular use, it refers to a type of component analog video (CAV) information that is transmitted or stored as three separate signals. Component video can be contrasted with composite video in which all the video information is combined into a single signal that is used in analog television. Unlike composite, component cables do not carry audio and are often paired with audio cables.


When used without any other qualifications, the term component video usually refers to analog YPBPR component video with sync on luma (Y) found on analog high-definition televisions and associated equipment from the 1990s through the 2000s when they were largely replaced with HDMI and other all-digital standards. Component video cables and their RCA jack connectors on equipment are normally color-coded red, green and blue, although the signal is not in RGB. YPbPr component video can be losslessly converted to the RGB signal that internally drives the monitor; the encoding is useful as the Y signal will also work on black and white monitors.


Reproducing a video signal on a display device (for example, a cathode ray tube; CRT) is a straightforward process complicated by the multitude of signal sources. DVD, VHS, computers and video game consoles all store, process and transmit video signals using different methods, and often each will provide more than one signal option. One way of maintaining signal clarity is by separating the components of a video signal so that they do not interfere with each other. A signal separated in this way is called "component video". S-Video, RGB and YPBPR signals comprise two or more separate signals, and thus are all component-video signals. For most consumer-level video applications, the common three-cable system using BNC or RCA connectors analog component video was used. Typical formats are 480i (480 lines visible, 525 full for NTSC) and 576i (576 lines visible, 625 full for PAL). For personal computer displays the 15 pin DIN connector (IBM VGA) provided screen resolutions including 640480, 800600, 1024768, 1152864, 12801024.


The various RGB (red, green, blue) analog component video standards (e.g., RGBS, RGBHV, RGsB) use no compression and impose no real limit on color depth or resolution, but require large bandwidth to carry the signal and contain a lot of redundant data since each channel typically includes much of the same black-and-white image. At one time, computers offered this signal via a VGA port. Many televisions, especially in Europe, utilize RGB via the SCART connector. All arcade video games, other than early vector and black-and-white games, use RGB monitors.


Further types of component analog video signals do not use separate red, green and blue components but rather a colorless component, termed luma, which provides brightness information (as in black-and-white video). This combines with one or more color-carrying components, termed chroma, that give only color information. Both the S-Video component video output (two separate signals) and the YPBPR component video output (three separate signals) seen on DVD players are examples of this method.


Digital component video makes use of single cables with signal lines/connector pins dedicated to digital signals, transmitting digital color space values allowing higher resolutions such as 480p, 480i, 576i, 576p, 720p, 1080i, and 1080p.[1]


RGB component video has largely been replaced by modern digital formats, such as DisplayPort or Digital Visual Interface (DVI) digital connections, while home theater systems increasingly favor High-Definition Multimedia Interface (HDMI), which support higher resolutions,[citation needed] higher dynamic range, and can be made to support digital rights management. The demise of analog is largely due to screens moving to large flat digital panels as well as the desire for having a single cable for both audio and video, but also due to a slight loss of clarity when converting from a digital media source to analog and back again for a flat digital display, particularly when used at higher resolutions where analog signals are highly susceptible to noise.


In a composite signal, such as NTSC, PAL or SECAM, the luminance, Brightness (Y) signal and the chrominance, Color (C) signals are encoded together into one signal. When the color components are kept as separate signals, the video is called component analog video (CAV), which requires three separate signals: the luminance signal (Y) and the color difference signals (R-Y and B-Y).


Component video connectors are not unique in that the same connectors are used for several different standards; hence, making a component video connection often does not lead to a satisfactory video signal being transferred. Many DVD players and TVs may need to be set to indicate the type of input/output being used, and if set incorrectly the image may not be properly displayed. Progressive scan, for example, is often not enabled by default, even when component video output is selected.
