A television screen contains 1080X860 Pixels (Picture Element). This screen refreshes at a rate of 30 pages /sec. if the color of each of these RGB pixels is defined by 3 bytes.
How much is the needed transmission rate in bps in such a system?
Question:
A television screen contains 1080X860 Pixels (Picture Element). This screen refreshes at a rate of 30 pages /sec. if the color of each of these RGB pixels is defined by 3 bytes.How much is the needed transmission rate in bps in such a system?
Sol:
Total number of pixels per frame in the television screen is 1080 x 860 = 928800 Pixels.
Each pixel is defined by 3 bytes of information.
Therefore bytes per frame= total number of pixels per frame x bytes per pixel = 928800 *3 Bytes = 2786400 Bytes
The screen refreshes at a rate of 30 pages /sec. So there is 30 frames per second.
Needed Transmission rate (bytes/sec) = number of bytes per frame x frames per second = 2786400 x 30 = 83592000 bytes per second = 79.72 megabytes per second
Needed Transmission rate in bps (bits/sec) = 637760000 bits per second
