Typically this is caused by latency or dropped packets on your Wi-Fi network (Router, not internet). The main cause of choppy, slow or delayed video and audio is due to network conditions that are less than ideal. Not only is bandwidth a requirement, but the network must be free of interference and latency. Normal internet use on a network will rarely show any signs of high latency. However, latency will interfere with AirPlay applications like AirParrot.
You may not notice choppy or less than ideal streams with standard AirPlay from iTunes or other applications. These applications are not real time and buffer content before transmission. As our applications use real-time mirroring, we're unable to buffer any content that's being played back.
Packet loss is the chief cause of lag issues, but latency can simulate packet loss in very poor networks because the timeouts for AirPlay traffic are so low that if the latency is greater than ~300ms, the packet will be lost and have to be retransmitted. Because AirPlay requires guaranteed transmission, any dropped packets have to be resent. This will cause the lag to continue to build until the network clears, or until screen movement reduces bandwidth and it can catch up.
What can you do about this? Internet download speed is not a factor, because AirParrot does not use the internet. It only uses the local connection through your router. We recommend an 802.11n router with 5Ghz support or a direct ethernet connection, but realize that's not always possible.
Make sure your router's firmware is up to date and give it a reboot to refresh the connection. Try changing the channel within your router, as this may eliminate static interferences.
If these steps do not help, we recommend temporarily connecting your computer to the Apple TV with an ethernet cable in order to eliminate the network as being the root cause of this issue. If you can’t use ethernet, try decreasing the distance between your computer, router and Apple TV, avoiding doors and walls when possible.
If you try these steps and are still experiencing this issue, it’s possible that your computer is simply having trouble keeping up with the encoding side of things. Try setting the quality to medium from within AirParrot’s Preferences.
