How many horizontal lines are there in a complete 720p video frame?

• A. 480
• B. 720
• C. 1080
• D. 1440

Answer: (B)

A complete 720p video frame contains 720 horizontal lines. The term "720p" refers to the resolution, which consists of 1280 pixels in width and 720 pixels in height, meaning that there are 720 distinct horizontal lines that make up the vertical resolution of the image. This resolution is classified as high-definition and is commonly used in various broadcasting and streaming services. Higher resolutions, such as 1080p, would include even more horizontal lines, which support more detailed images, but for 720p, the count remains at 720 lines. Understanding this concept is crucial for professionals working in television operations, as it relates directly to the quality and clarity of the video content being delivered.
