Game Data Live can utilize a File Transfer Protocol server to improve performance and make your Game Data Live network more robust. When you transfer video from one iPad to another, both ends of that transfer use wireless communications. When you use a FTP server, the sending iPad transfers the file to the server and then sends a message to the receiving iPad to get the video from the server. The FTP server is wired to your router which makes both transfers more efficient. Benefits of using an FTP server include:
- Faster video file transfers. This enables you to use higher quality video formats.
- One sending iPad can transfer a video file to multiple receiving iPads.
- Refreshing a game can include links to server based video files - If your network connection gets interrupted, you can refresh your data and download the video files you missed.
Using just a router with a flash drive nearly doubles file transfer speed. To transfer a video from one iPad to another takes two transfers, so the total transfer takes about the same time, but the sending iPad is done in half that time.
Setting this up will take some effort. Its not expensive. The three benefits listed above are definitely worth the effort. We have tested with the following FTP servers.
A Router that can share a disk drive. We used a USB-3.0 flash drive that you can purchase for under $20. We have done this with several Linksys routers.
A Macintosh computer running an old version of Mac OS X which can Share Files and Folders using FTP and provides Web Sharing for Free.
A newer Macintosh computer running Mac OS X Server. Upgrading your Mac OS X to Mac OS X Server costs $20.
Note that Apple stopped providing a FTP server with macOS High Sierra. Apple's FTP server also seems to have problems when Game Data Live and the server are running on the same machine - before macOS High Sierra. We're investigating alternate solutions.
Video file transfers using a Macintosh based FTP server can be half a second faster than a router with a flash drive.
Video captured by a Macintosh can be copied to the server directory in the same Mac (before High Sierra) in a fraction of a second. That video can be delivered to other Macs on a wired network in about a second.
