Patent ID: 8891014

Claim:
A method of stabilizing display latency in a video transmission over an IP network, the method comprising: receiving a source signal from a source via an IP network, the signal comprising data associated with a plurality of source frames, each source frame in the plurality of source frames associated with a distinct timestamp from a common clock shared between the source and a renderer, each source frame indicative of an image to be displayed on a renderer; generating a display signal comprising data associated with a plurality of display frames, each display frame corresponding to a source frame, the display signal configured to cause the renderer to display the image; and stabilizing a display latency between the plurality of source frames in the source signal and the plurality of display frames in the display signal, such that the display latency is non-oscillating, comprising syntonizing a frequency of the source signal and a frequency of the display signal; detecting whether the frequency of the source signal and the frequency of the display signal are locked; and if the frequency of the source signal and the frequency of the display signal are locked: synchronizing a phase of the source signal and a phase of the display signal; generating correction data based in part on synchronization of the phase of the source signal and the phase of the display signal; and re-syntonizing the frequency of the source signal and the frequency of the display signal using the correction data.
