Pal TV 📺 System

The PAL (Phase Alternating Line) TV system is one of the main analog color television encoding systems used across the world. Developed in the early 1960s in Germany by Walter Bruch at Telefunken, PAL was designed to improve upon the NTSC system, especially in terms of color stability and picture quality.Lines and Frame Rate: PAL uses 625 horizontal lines and a frame rate of 25 frames per second (50 fields per second interlaced), which matches the 50 Hz power grid common in Europe, Asia, Africa, and Australia.PAL alternates the phase of the color signal (chrominance) every line, which helps cancel out color errors caused by signal distortion. This makes the image color more stable and accurate compared to NTSC.Bandwidth: A standard PAL signal uses about 5.5 MHz for video and 5.5–6.0 MHz total with audio.Region Use: PAL is used widely in Europe, Asia, Africa, Australia, and parts of South America. Different countries may use slightly modified versions (like PAL-B, PAL-G, PAL-I, etc.) depending on local broadcasting standards.NTSC (used mainly in North America and Japan): Has fewer lines (525) and a faster frame rate (29.97 fps), but is more prone to color errors.SECAM (used in parts of Eastern Europe and France): Has a different way of encoding color, generally more resistant to signal interference, but not as good for editing or copying.Most countries have now switched to digital TV broadcasting, using systems like DVB-T, ATSC, or ISDB, but PAL was the backbone of analog television for decades and influenced many aspects of modern broadcasting. 📺 🖥 📺 🖥
