Abstract

L'invention concerne un procédé et un appareil de commande de terminal. Le procédé de commande de terminal comprend les opérations suivantes : lors de la réception d'une requête OPTION envoyée par un client RTSP, une extrémité de desserte RTSP renvoie une réponse OPTION qui transporte un procédé de commande de dispositif préétabli au client RTSP, pour que le client RTSP établisse une connexion RTSP avec l'extrémité de desserte RTSP sur la base de la réponse OPTION reçue ; l'extrémité de desserte RTSP reçoit une requête de commande de dispositif envoyée par le client RTSP sur la base du procédé de commande de dispositif reçu par l'intermédiaire de la connexion RTSP établie, la requête de commande de dispositif comprenant d'autres requêtes de commande autres qu'une commande de flux multimédia ; et l'extrémité de desserte RTSP extrait un paramètre de commande transporté par la requête de commande de dispositif reçue sur la base du procédé de commande de dispositif, et réalise une action correspondant au paramètre de commande. La présente invention peut réduire la consommation de réseau entraînée par une autre commande sur l'extrémité de desserte RTSP autre que la commande de flux multimédia.
