MESSAGE INFORMATION TRANSMITTING AND RECEIVING METHOD, DEVICE AND SYSTEM

摘要

A method, apparatus and system for sending and receiving notification messages to synchronize notification messages with program streams accurately. The method for sending notification messages includes: obtaining a notification message and a synchronization timestamp that are synchronous with a program; encapsulating the notification message into an RTP/RTCP packet corresponding to the synchronization timestamp; and sending the RTP/RTCP packet to a terminal. The method for decapsulating notification messages includes: receiving an RTP/RTCP packet that carries a notification message; and decapsulating the RTP/RTCP packet to obtain the notification message. Embodiments of the present invention synchronize a notification message with a program stream accurately by carrying the notification message in an RTP/RTCP packet.
