What is PAL?
PAL (Phase Alternating Line) is a colour encoding system used in analog television broadcasting. It was developed in Germany in the 1960s and adopted by India as the standard for terrestrial and cable TV transmissions. PAL works by alternating the phase of the colour signal on each scan line, which corrects hue errors and provides consistent colour reproduction. In India, PAL was implemented in the B/G variant (PAL-B/G) and remained the dominant TV standard until the transition to digital broadcasting in the 2010s. Doordarshan, India’s public broadcaster, used PAL for its national network. The system is still relevant in legacy devices, video game consoles, and vintage TV sets. For competitive exams like UPSC and state PCS, PAL is often mentioned under communication technology and mass media topics, especially in the context of India’s broadcasting history. Understanding PAL helps students grasp the evolution from analog to digital TV, including the role of standards in global media. Though largely obsolete, PAL remains a foundational concept in electronics and communication engineering curricula in Indian universities.
