Abstract
Systems, methods, and apparatuses are disclosed for overcoming latency and loss of signal detection in remote control displays. An exemplary system includes a remote control, a host computing device, and one or more target systems communicatively coupled to each other over a wired and/or wireless network. One method includes receiving, by the remote control and from a host computing device, a first video frame captured by a target device, determining a first time corresponding to receipt of the first video frame, receiving, from the host computing device, a second video frame, determining a second time corresponding to receipt of the second video frame, comparing the time difference to a latency threshold, and causing an alert graphic element to be displayed indicating a latency in communication.
