What would happen in the match without SRS (smart replay system) and what will change now:

In earlier IPLs, the TV Broadcast Director acted as an intermediary between the Hawk-Eye operator and the third umpire. But that won’t happen now. Instead, TV umpires will take live video directly from the operator and will get footage from different angles simultaneously. That will make it easier to make the right decision. This type of technology was used by the England and Wales Cricket Board in The Hundred. But this time, this system will be used for the first time in IPL.

Know How Smart Replay System Will Help Umpires :

Suppose a player sets up to block the ball, it will be possible to know exactly how his feet and hands are at that moment. At the same time, it will be clear what exactly the player is doing through various angles. When stumping, catch and dismissal decisions have to be made, this system is going to be of best use. Because different angles can be available simultaneously and everything can be seen clearly.

How the Smart Replay System will work, see :

Suppose a fielder bowls the ball towards the stumps. The ball hit the stumps and the ball went out of bounds. Now with the new smart replay system it will be possible to see if the batsmen crossed each other while making the throw or not. This will involve the use of high-speed cameras installed around the field to record the exact moment the fielder releases the ball. This time there is a similarity between DRS and this smart replay system. The TV umpire conversation will continue to reach the fans as before. This can help fans understand why any decision has been made.
