System for synchronizing display of data transmitted wirelessly

A system for synchronizing displays of data transmitted wirelessly, comprising:

• a source device configured for outputting a first video signal;
• a signal processing device connected to the source device and configured for transforming the first video signal into a second video signal;
• and
• a plurality of display devices connected to the signal processing device, the display devices configured for receiving the second video signal from the signal processing device via wireless transmissions and displaying the second video signal;
• wherein the signal processing device includes a timer, the timer is configured to calculate a first time interval for transmitting an expected signal between the signal processing device and the display devices, and outputs a first control signal, the signal processing device transforms the first video signal according to the first control signal, a time duration of displaying the second video signal is longer than the first time interval and a file size of the second video signal is smaller than a file size of the expected signal, the display device includes a signal receiver, a temporary storage device connected to the signal receiver, and a display connected to the temporary storage device, the signal receiver is configured to receive the second video signal from the signal processing device, the temporary storage device is configured to save the second video signal, the display is configured to display the second video signal.
