The Nature of Video Signals
Video signals are exquisitely complex waveforms that encode several types of information about a scene. Typically a scene is scanned at the transmit end and converted into a number of lines or pixels per scene. The lines from the decomposed scene can be thought of as a series of pixels. Generally a series of lines comprises a TV signal, while computer displays use a pixel-based configuration.
General Characteristics of all Video Formats
A usable video waveform conveys the following information:
• Brightness (luminance) of each pixel
• The color (hue) of each pixel
• Color saturation information
• Precise location of the pixel on the display
Of course, to keep the image's appearance smooth and continuous, ...
