Abstract
A method and system for conditioning a media stream for splicing are disclosed. In an embodiment, content-specific splice points, which correspond to a possible playout splice point within an original media stream, are identified for both audio and video components of the original media stream. Once the audio bitstream and video bitstream splice points are identified, the audio bitstream in the vicinity of the audio bitstream splice point is packetized into IP packets containing only audio with one of the audio-containing IP packets having an IP packet boundary that corresponds to the audio bitstream splice point and the video bitstream in the vicinity of the video bitstream splice point is packetized into IP packets containing only video with one of the video-containing IP packets having an IP packet boundary that corresponds to the video bitstream splice point. The conditioned original media stream is then transmitted downstream to a splicer.
