Definitions

  • Invention name Timeout retransmission method and system for video conference
  • the present invention belongs to the field of communications, and in particular, to a method and system for re-transmitting a video conference.
  • Conference is a common communication method in the current society. Especially for the staff, it needs to participate in many conferences. The existing conferences are divided into teleconferences and on-site conferences. Now the video of the conference is generally played. If delay occurs, it will be resent along the original path. This method is generally longer.
  • the present invention is implemented in this way, a method for super-retransmission of a video conference, the method comprising the following steps [0005] 101, detecting an extension of video conference data;
  • the method further includes:
  • a super-retransmission system for a video conference includes:
  • a delay module configured to detect an extension of the video conference data
  • a scanning module configured to acquire a path of the last successfully transmitted data packet if the delay exceeds a threshold between the delays
  • a retransmission module configured to send the retransmission data packet along a path of the last successfully transmitted data packet.
  • the system further includes:
  • the alarm unit is configured to perform an alarm when the retransmission packet delay exceeds the inter-turn threshold.
  • FIG. 1 is a flowchart of a method for super-retransmission of a video conference provided by the present invention
  • FIG. 2 is a structural diagram of a super-retransmission system for a video conference provided by the present invention.
  • a specific embodiment of the present invention provides a method for resending a video conference.
  • the method is as shown in FIG. 1 and includes the following steps:
  • the technical solution provided by the present invention does not use the original path retransmission, and uses the path transmission of the last successful transmission of the data packet, which can avoid the delay of extending the link problem by itself.
  • the foregoing method may further include:
  • a specific embodiment of the present invention further provides a video conference super-retransmission system, which is shown in FIG.
  • the delay module 201 is configured to detect an extension of the video conference data
  • the scanning module 202 is configured to obtain the last successful number of transmissions if the delay exceeds the inter-turn threshold According to the path of the package;
  • the retransmission module 203 is configured to send the retransmission data packet along the path of the last successfully transmitted data packet.
  • the foregoing system further includes:
  • the alarm unit is configured to perform an alarm when the retransmission packet delay exceeds the inter-turn threshold.

Abstract

L'invention concerne un procédé et un système de retransmission de fin de temporisation de réunion vidéo. Le procédé comprend les étapes suivantes : 101. Détection d'un retard de données de réunion vidéo ; 102. Si ledit retard dépasse un seuil de temps, acquisition du trajet réussi le plus récent pour envoyer des paquets de données ; et 103. Envoi d'un paquet de données de retransmission le long du trajet réussi le plus récent pour envoyer les paquets de données. Le présent procédé a l'avantage de réduire le retard.
