METHOD AND SYSTEM FOR SPLICING ADVERTISEMENT, SPLICER AND HEAD END DEVICE

摘要

The present invention provides a method and system for splicing an advertisement, a splicer, and a head end device. The method includes: performing real-time transport protocol encapsulation processing on coded video data, to obtain a real-time transport protocol packet and/or a real-time transport protocol control protocol packet; and carrying splice information in the obtained real-time transport protocol packet or real-time transport protocol control protocol packet, and sending the real-time transport protocol packet or real-time transport protocol control protocol packet to a splicer, so that the splicer splices a received targeted advertisement into an advertisement avail of the video data according to the splice information in the received real-time transport protocol packet or real-time transport protocol control protocol packet. The method and system for splicing an advertisement, the splicer, and the head end device according to the present invention are used to solve the problem in the prior art that when encapsulation processing is performed on video data in RTP mode, the splicer cannot determine when to splice a received targeted advertisement into the encapsulated video data, thereby implementing advertisement insertion services.
