Green field county stadium is planning to conduct a cricket match between two teams a and b. a large crowd is expected in the stadium as 1 tickets have already been sold. to fulfill the viewers’ requirements, the match administrators are willing to install large display screens inside the stadium which should display the match “live” through several cameras installed on different angles in the stadium.

after carefully reading and analyzing the given scenario, you are required to suggest the “most suitable serial transmission mode” with two strong reasons.

format of your answer should be as follow:

mode name:
reason 1:
reason 2:

Mode Name:  RS-485, half duplex, 2 wire based for serial data transmission

Reason 1:   less noisy

Reason 2: around 32 receivers allowed, and that is enough for the requirement mentioned in this question.

Explanation:

Serial data transmission is of two types, which are synchronous data transmission and asynchronous data transmission. However, here continuous transmission is required, and hence no stop is required. Hence, it's the Synchronous data transmission. Also, you need to only transmit at a time from one transmitter, and no receiver or the screen is going to respond in that time, considering AI surveillance is not in progress meanwhile. However, we have 4 wire, full-duplex RS-485 also available, though here we need only 2 wire half-duplex RS-485. And this will certainly cater to our requirements. And we can but should not use RS-422A as the number of receivers, in that case, is limited to merely 10.
