Abstract
A network module receives network global positioning system (GPS) signals and that transmits a video signal to a remote device that includes time stamps that are based on the network GPS signals. The network module receives a device parameter from the remote device that indicates that local GPS signals are available to the remote device. The network module reduces a frequency of the time stamps when the device parameter indicates that local GPS signals are available to the remote device.
