Early Television Standards
Early television standards defined how images were transmitted and displayed, ensuring compatibility between broadcasters and receivers. These standards specified factors like resolution (detail level), frame rate (number of images per second), and scan type (interlaced or progressive). Initially, different regions adopted different standards, such as NTSC in North America, with 525 lines and approximately 30 frames per second, and PAL/SECAM in Europe with higher resolution and different frame rates. These standards laid the foundation for clear, consistent television images, evolving over time to improve picture quality and support new technology.
