![]() Limitations : Low resolution, not globally adaptable, demodulation losses. Maximum Resolution : 720 x 576 50 Hz, 720 × 480 59.94 Hzīenefits : As one of the first video signals, it was the best you could get from its introduction in 1956. Composite video is displayed in varying standard formats, such as NTSC (National Television System Committee, prevalent in North America), PAL (Phase Alternating Line, predominant in Europe), and SECAM (Sequential Color with Memory, principally in portions of Africa, the Middle East and other select regions) depending on the region in which you live. These carry low definition video signals only. This can lead to video errors because the luminance and chrominance signals overlap and are often difficult to separate, resulting in “dot crawl” and “rainbow” effects. Composite signals have to be decoded before they can be displayed. In composite video, the luminance, chrominance, and sync information are combined into a single signal. ![]() We have provided this guide to help you decipher the different types of video signals and their applications, and thus determine which will best suit your requirements.Ĭomposite*: Composite input is the commonly seen yellow RCA** cable. ![]() There are both analog and digital video signals, with different characteristics, advantages, and limitations. Video signals (also called “video inputs”) come in many flavors and they’re not always so easy to distinguish.
