Planning Multi Camera Setup

When initially planning on how we were going to achieve the television section we had numerous options. Green screen was one suggestion but we have decided on live streaming from multiple cameras directly to the TV screens. We were planning to film on multiple Black Magic Mini URSA's 4K to live stream into the TV's but the camera does not have a HDMI output meaning that we cannot use the cameras unless we buy multiple very expensive convertors which is unlikely to happen with our very tight budget. 

In conclusion, we have opted to use slightly older cameras that can also be wired by HDMI into the TV's we have available to us. We will be using 8 TV's and possibly 5 cameras including the Black Magic Mini URSA 4k to film the TV screens itself.
