Abstract
(EN)
Disclosed are a method for monitoring a terminal through an IP network and an MCU, which are applied to video conference systems. The method comprises: acquiring data from terminals, the terminals comprising at least one of an E1 terminal and a 4×E1 terminal; converting the acquired data into data in an IP protocol format; and packaging the converted data and sending the packaged data to a monitoring device through an IP network. Through the technical solution provided by the present invention, different types of video and audio data can be converted into a uniform format and then sent to a PC, thereby meeting the demand that the monitoring system supports multiple types of audio and video data.

La présente invention concerne un procédé de surveillance d'un terminal via un réseau IP et un MCU, qui est appliqué aux systèmes de vidéo conférence. Le procédé consiste à : acquérir des données auprès de terminaux, les terminaux comprenant au moins l'un d'un terminal E1 et d'un terminal 4×E1 ; convertir les données acquises en des données dans un format de protocole IP ; et empaqueter les données converties et envoyer les données empaquetées à un dispositif de surveillance via un réseau IP. Grâce à la solution technique fournie par la présente invention, différents types de données vidéo et audio peuvent être convertis dans un format uniforme, puis envoyés à un PC, répondant ainsi à la demande de prise en charge par le système de surveillance de plusieurs types de données audio et vidéo.
