TV standards refer to the technical specifications and formats used in broadcasting television signals and displaying video content on television screens.There are several TV standards used globally, each with different specifications regarding resolution, aspect ratio, refresh rate, and other features. Here are some of the common TV standards:

• Refresh Rate: 60 Hz (NTSC) or 50 Hz (PAL)

2. High Definition (HD):

• Resolution: 1280x720 pixels (720p) or 1920x1080 pixels (1080p)
• Aspect Ratio: 16:9 (widescreen format)

5. High Dynamic Range (HDR):

HDR standards, such as HDR10, Dolby Vision, and HLG, enhance the contrast and color range of TV displays, providing a more lifelike and vibrant viewing experience. HDR content preserves details in the brightest and darkest areas of a picture that are lost using standard dynamic range (SDR) technology.

6. Frame Rate:

• Most TV content is displayed at 24, 30, or 60 frames per second (fps). Higher frame rates can provide smoother motion, which is especially beneficial for fast-paced action scenes and gaming.

7. Broadcast Standards:

• Different regions use specific broadcast standards, such as ATSC in North America and DVB in Europe, to transmit digital television signals over the airwaves.

Understanding these standards can help consumers make informed decisions when purchasing TVs or other display devices, ensuring compatibility with the content they want to watch or play. Different standards are used depending on the source of the content (broadcast TV, streaming services, gaming consoles, etc.) and the capabilities of the viewing device.
