VIDEO SIGNAL Meaning and
Definition
-
A video signal refers to an electronic signal that carries visual information in various formats and resolutions. It is a representation of a moving or still image that can be transmitted or stored electronically. A video signal is typically composed of a series of images known as frames, which change rapidly to create the illusion of motion. It contains essential components that convey both the brightness (luminance) and color (chrominance) information required for creating a visual display.
A video signal can be analog or digital in nature. In analog video signals, information is represented by continuously varying voltages or currents. These signals are commonly found in older technologies, such as traditional television systems. Digital video signals, on the other hand, convert visual information into binary code, which consists of ones and zeros. Digital signals are widely utilized in modern devices like computers, smartphones, and high-definition televisions.
Furthermore, the video signal can be transmitted through various mediums, including cables, airwaves, or fiber-optic networks. It is commonly used in applications such as broadcasting, video conferencing, surveillance systems, gaming consoles, and video playback devices.
The quality of a video signal is influenced by factors like resolution, frame rate, color representation, and compression techniques. These aspects determine the clarity, smoothness, and overall fidelity of the visual content displayed. Advancements in video signal technology have facilitated the development of high-definition (HD) and ultra-high-definition (UHD) video standards, which offer superior image quality and more immersive viewing experiences.
