Claim 15:
16. The device according to claim 11, wherein the viewing node establishing the video relay session with the relay node, and receiving, reassembling, decoding and playing the fragment of video data, and at the same time regularly recording relay behavior data to the system further comprises:
the viewing node establishing a video relay session with a previous relay node, and the relay node submitting a newly added session request comprising the current relay session identifier and a corresponding previous relay session identifier to the relay session module; wherein the request comprises the current video relay session identifier, the previous relay video session identifier corresponding to the current session, and a login session identifier of the viewing user;
the relay session module verifying whether the previous relay video session exists:
if not, returning a request failure message and stopping receiving the video;
if yes, the relay session module recording the current relay session identifier, and returning a successful recording message to the relay node, and then the relay node sending the relayed fragment of video data to the viewing node, and the following steps continuing to be performed;
the viewing node sending a relay request to the relay node to request the relay node to continue to relay a next relay period threshold duration to the viewing node; wherein request information mainly comprises a current relay video session identifier, a maximum video slice number of a previous relay, a login identifier of the viewing user, and a time point of the current relay request;
the viewing node receiving the fragment of video data and performing operations of reassembling, decoding and playing video; and
the viewing node determining whether it is time to send the relay request, that is, within a time interval less than a relay period threshold since a previous relay request was sent:
if not, the viewing node continuing to wait and receiving the fragment of video data to perform the operations of reassembling, decoding and playing video; and
if yes, the viewing node initiating a recording request for writing a relay behavior to a relay behavior recording module, and sending a relay request to the relay node.
