Difference between RCA and AV
The RCA interface is the AV port itself (the name is mainly reflected in the size of the interface), and the AV interface refers to the purpose of the interface.
This can be simply read as: RCA is the same as AV
realme Smart TV supports the RCA connection to red white and yellow cables.
Note:
For realme Smart TV 43'', realme Smart TV 4K 43" and realme Smart TV 4K 50", these three models only have a mini AV port. When using Mini AV Port(3.5mm), please buy a Mini AV line first.
