PAL Broadcast Standard

Phase Alternating Line or PAL is the European broadcast video standard introduced in the early 1960s. A PAL image includes 625 lines of 720 pixels, interlaced @ 50 fields per second. The PAL analog signal is broadcast at 50 Hz over the airwaves in Europe and other countries throughout the world. Most countries around the world use one of three main television broadcast standards. These three main standards are NTSC, PAL and SECAM. However, each standard is incompatible with the other. For example, a video recording made in the UK (PAL format) could not be played on US standard VCR’s (NTSC Format) or shown on the TV in the United States. Countries on the PAL system include the U.K., Germany, Spain, Portugal, Italy, China, India, most of Africa, and the Middle East.
