PAL is telecasting format has
(A) 30 fps 525 lines per frame
(B) 30 fps 625 lines per frame
(C) 25 fps 625 lines per frame
(D) 25 fps 525 lines per frame
Correct Ans: (C)
The PAL telecasting format stands for Phase Alternating Line. It is a widely used television broadcasting standard in many countries, especially in Europe, Asia, and parts of Africa. One of its defining features is that it operates at 25 frames per second (fps). Along with that, each frame contains 625 lines, which enhances image clarity.
Initially, the PAL system was developed to address colour distortion issues found in older formats. Therefore, it introduced alternating phase shifts in the colour signal. This shift helped balance out errors and maintained colour consistency across frames. As a result, viewers experience smoother, more natural visuals.
Moreover, the 25 fps speed synchronizes well with the 50 Hz power supply used in these regions. This synchronization reduces flicker on screens, which in turn ensures a more stable picture. Because of the higher line resolution (625 lines) compared to NTSC’s 525 lines, PAL typically offers sharper images and better colour fidelity.
In contrast, NTSC—the American standard—operates at 30 fps with 525 lines. While NTSC may show slightly smoother motion, PAL excels in detail and accuracy. Consequently, filmmakers and TV producers working in PAL regions often prioritize clarity over motion fluidity.
To summarize, the PAL telecasting format functions with 25 fps and 625 lines per frame. This combination allows it to deliver high-resolution visuals and consistent colour performance, making it ideal for quality television broadcasting.
