Q3. What is NTSC and PAL?
NTSC (National Television System Committee) is the first color TV broadcast system that was implemented in the United States in 1953. This was based on the NTSC - National Television System Committee standard. NTSC is used by many countries on the American continent as well as many Asian countries including Japan. NTSC runs on 525 lines/frame.

PAL (Phase Alternating Line ) was introduced in the early 1960's and implemented in most European countries except for France. The PAL standard utilizes a wider channel bandwidth than NTSC which allows for better picture quality. PAL runs on 625 lines/frame.
