QuakeTV is a common name for applications with a common purpose - to broadcast Quake matches to big amount of observers.
Bandwidth requirements
- 4on4 match takes around 7kB/s
- 2on2 match takes around 3kB/s
- 1on1 match takes ardoun 1,5kB/s
- QTV to server takes ALWAYS only 7kB/s max (depending on the game mode)
- One QTV connected, 4 ports running 4on4 would be 1*4*7kB/s = 28kB/s between QTV and Servers
- QTV to client takes number of clients * 7kB/s max (depending on game mode)
- One QTV connected, 4 ports running 4on4 each, 10 specs on each = 1*4*10*7kB/s = 280kB/s
Requirements
- ezQuake 1.9 build 2105 or newer, or
- FTE 3343 or newer
Common client commands
/cmd users or /qtvusers to check connected clients
/cmd lastscores similar to KTX lastscores command
/demo_autotrack 1/0 uses KTX autotrack information stored in the stream (so they should be identical in KTX and QTV).
/autotrack with ezQuake 1.9 stable will be the same as above. So you can use your existing 'autotrack' bind for the same function while on QTV
Clientside variables for ezQuake

| Maxspectators | ~100 | thousands | |
| Bandwidth usage | max server allowed | 7kB/s 4on4 | depends on the number of players |
| Server cpu usage | same as for player | 0% | on 2GHz K8-cpu one player takes 1% cpu |
| Autotrack | yes | yes | |
| Follow commentator | always | switchable | |
