One Horizontal Time is the number of times per second that a raster-scan video system transmits or displays a complete horizontal line. It is a crucial parameter in video display systems and raster scanning technologies.
The calculator uses the formula:
Where:
Explanation: This formula calculates the time taken for one horizontal line transmission by dividing the vertical retrace time by the number of horizontal lines lost during the process.
Details: Accurate calculation of one horizontal time is essential for optimizing video display performance, ensuring proper synchronization in raster-scan systems, and maintaining image quality in video transmission systems.
Tips: Enter Vertical Retrace Time in seconds and Horizontal Lines Lost as a numerical value. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is Vertical Retrace Time?
A: Vertical Retrace Time is a measurement of time related to video displays that represents the time taken for the electron beam to return from the bottom to the top of the screen.
Q2: What are Horizontal Lines Lost?
A: Horizontal Lines Lost is defined as the number of times per second that a raster-scan video system transmits or displays a complete horizontal line that is not visible on the screen.
Q3: Why is One Horizontal Time important in video systems?
A: One Horizontal Time determines the scanning rate and synchronization of horizontal lines in raster display systems, affecting the overall image quality and stability.
Q4: What are typical values for One Horizontal Time?
A: Typical values vary depending on the video standard, but generally range from microseconds to milliseconds for different display systems.
Q5: Can this calculation be used for modern digital displays?
A: While primarily designed for traditional raster-scan systems, the concept remains relevant for understanding timing parameters in various display technologies.
