Number of Lines in Frame Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Lines in Frame = Horizontal Frequency/Number of Frames per Second
N_L = f_hzl/FPS
This formula uses 3 Variables

Variables Used

Number of Lines in Frame - Number of Lines in Frame refers to the total number of horizontal lines that make up a complete frame of a video signal.
Horizontal Frequency - (Measured in Hertz) - Horizontal Frequency usually expressed in kilohertz is the number of times per second that a raster-scan video system transmits or displays a complete horizontal line.
Number of Frames per Second - Number of frames per second is the total no. of frames in a second.

STEP 1: Convert Input(s) to Base Unit

Horizontal Frequency: 48 Hertz --> 48 Hertz No Conversion Required
Number of Frames per Second: 24 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N_L = f_hzl/FPS --> 48/24

Evaluating ... ...

N_L = 2

STEP 3: Convert Result to Output's Unit

2 --> No Conversion Required

FINAL ANSWER

2 <-- Number of Lines in Frame

Height of Rectangle Picture Frame

Go Height of Rectangle Picture Frame = Width of Rectangle Picture/Aspect Ratio

Width of Rectangle Picture

Go Width of Rectangle Picture = Height of Rectangle Picture Frame*Aspect Ratio

Number of Lines in Frame

Go Number of Lines in Frame = Horizontal Frequency/Number of Frames per Second

Number of Frames Per Sec

Go Number of Frames per Second = Horizontal Frequency/Number of Lines in Frame

Aspect Ratio

Go Aspect Ratio = Width of Rectangle Picture/Height of Rectangle Picture Frame

Horizontal Resolution

Go Horizontal Resolution = Video Bandwidth*(2*One Horizontal Line Scan)

Number of Horizontal Lines Lost during Vertical Retrace

Go Horizontal Lines Lost = Vertical Retrace Time/One Horizontal Time

Vertical Retrace Time

Go Vertical Retrace Time = Horizontal Lines Lost*One Horizontal Time

Kell Factor or Resolution Factor

Go Kell Factor = Horizontal Lines Lost/Number of Lines in Frame

Vertical Resolution (VR)

Go Vertical Resolution = Number of Lines in Frame*Kell Factor

Number of Lines in Frame Formula

Number of Lines in Frame = Horizontal Frequency/Number of Frames per Second
N_L = f_hzl/FPS

How many lines does a frame in TV signal is scanned?

The NTSC TV standard uses an aspect ratio of 4:3 (ratio of picture width to height), and 525 scan lines per frame at 30 fps. Each frame has an odd field and an even field. So there are 525/2 = 262.5 lines per field. NTSC actually uses 29.97 fps.
