Video output
In the field of computer science, video release is used to designate the element that allowsissue information and images from a computer to a device.
Computer displays vary depending on the type of computer. Each device has a scanning mode and specific resolutions. The 8bis, 16-bit and 32-bit microcomputers were designed to be plugged into a TV. They have a video output in 740/50 or 525/60. The standards are not the same for PCs. For example, for a VGA PC they are 640x48x16c to 60Hz. The standard formats of the images come in an infinite number of color variations.
The scanning frequency ranges from 50 Hz to more than 120 Hz. Because of this difference in scanning frequencies, a computer cannot be plugged directly into a TV. An attempt to connect these two devices directly between them could destroy the television set. In addition, it is essential to use a color encoder (NTSC, PAL or SECAM) to record computer images on video. Thus, the video output is independent of that dedicated to the monitor on some computers.
As technology continues to advance, there is now a video output on the market that works with new generations of USB (Type C) sockets. This technology succeeds the MHL standard and offers the ability to stream videos in very high definition via a USB Type C connector. With this interface, users can connect their smartphone to a TV provided they have a suitable chip.
