First Claim
Patent Images
1. A method, comprising:
- receiving images and sync messages, by a receiving system, from a sending system;
the receiving system computing a time difference between a current time and a time a last sync message was received from the sending system; and
when said time difference meets or exceeds a first threshold, generating an alert that indicates that a received image may be stale.

Abstract
A method for indicating stale data whereby a receiving system receives images and sync messages from a sending system and computes a time difference between a current time and a time a last sync message was received from the sending system. If such a time difference meets or exceeds a first threshold, the an alert is generated.

10. A system, comprising:
-
a receiver that receives images from a sending system; wherein said receiver determines a time difference between a current time and a time a last sync message was received from a sending system, and, when the time difference meets or exceeds a first threshold, the receiver generates an alert that indicates that a received image may be stale. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A system, comprising:
-
a receiver having a display; and a sender remotely coupled to said receiver, said sender sends images to the receiver to be shown on the display; wherein said receiver determines a time difference between a current time and a time a last sync message was received from a sending system, and, when the time difference meets or exceeds a first threshold, the receiver generates an alert that indicates that a received image may be stale. - View Dependent Claims (19, 20, 21, 22)

23. A computer-readable medium containing software that, when executed by a processor, causes the processor to:
-
receive images and sync messages from a sending system; compute a time difference between a current time and a time a last sync message was received from the sending system; when said time difference meets or exceeds a first threshold, generate an alert that indicates that a received image may be stale. - View Dependent Claims (24, 25)
