Claim 6:
7. The method for preventing a fraudulent video relay according to claim 6, further comprising:
the relay node determining whether the relay request is received after the viewing node sending the relay request to the relay node:
if yes, the relay code further determining whether the request is legal based on whether the current video relay session identifier of the request exists; if it does not exist, ignoring it; if it exists, the relay node extending a active duration of a relay session corresponding to the request to the next relay period threshold duration, and continuing to relay the fragment of video data to the viewing node corresponding to the request;
if not, the following operations continuing to be performed; and
the relay node polling to check whether each session relayed to the next node has expired:
if yes, the relay node canceling the relay session, terminating a relay forwarding operation corresponding to the session, and returning to continue waiting for a next relay request or determining whether the relay session has expired; and
if not, returning to wait for the next relay request or continue to check whether the relay session has expired.
