Dynamic program insertion in high quality video over IP
Taehyun Kim, Jack Brassil · 2003
We introduce an overlay network architecture and signaling mechanism that permit program insertions in live, high quality video streams transmitted over IP networks. We describe the implementation of an application proxy that dynamically inserts pre-recorded video programs into NTSC D1 quality Motion-JPEG streams with no visible artifacts. As increases in computing power further enable the modification of video during transport, new services such as personalized commercial advertisement insertions promise to make IP distribution an attractive alternative to conventional broadcast network distribution.
