What is a folded video?
Composite video is the most common type of video interface for sending or receiving an analog video signal to or from a TV file. The composite video interface can connect the VHS tape player, DVD player or game console to the TV. The three connectors together provide an interface for audiovisual connection. The red RCA Jack combines the right channel of the stereo system while the white RCA jack connects the left. Yellow composite video jack completes the set.
Stream video consists of y for luminescence or black and white values and c for chrominance or color. The Y signal provides brightness and contrast, allowing deep rich blacks and surprising bright white. The quality of this signal is particularly evident in low illuminated scenes, where the degraded signal translates into "faded" blacks and muted white, making it difficult to resolve the scenery or action. Color signal- or RGB for red, green and blue - bears information afterTřebná to create changing shades. The degraded signal C can result in coloring that is not faithful to its resources.
The composite video is thus named because the Y/C signals are compressed and directed by a single conductor to be separated by a "comb filter" inside the television file. Although composite video has been standard for many years, the process itself causes some degradation of signal integrity. In the past, this was not a problem, because television resolution and audiovisual equipment in general were lower than today's standards. However, with the advent of TV and high -resolution DVDs, the disadvantages of the composite video on the screen appeared.
The composite video restriction led to the S-Video, the mini-din interface, which does not sit Y/C separately, each of which acquires its own wire wrapped in a single cloak to appear as the only cable. S-video is also analogue and still requires soundBely.
Recently, the S-Video has been replaced by a component video that isolated not only the Y signal on its own cable, but also red and blue signals, while green values are derived when reading other data streams. The component video requires three cables plus sound cables, a total of five cables. The latest improvement in audiovisual interfaces is a high -resolution multimedia interface (HDMI), a real digital interface that combines video and sound into a single cable, while maintaining perfect integrity. This digital standard is the most sought -after interface that is currently available.
As manufacturers try to maintain their latest products compatible with older components, there may be three, four or even five options for video connection to your equipment. While the composite video is an adobed standby mode, using the available video interface of the highest quality, it allows you to get the most out of your investment.
