Abstract
Over the past few years, video transmission over IP network has become increasingly popular. However, the majority of research work in the area has concentrated on distribution, i.e. how to transmit TV signal to home users via internet. Video contribution over IP (VCIP), for use by broadcasters and program makers, is still a relatively new field and so far little research been carried out in this area.

This paper will introduce the VCIP work that has been done by BBC Research over the past few years. We will talk about the testing of various VCIP coders/decoders – problems unique to VCIP will be highlighted. We will also look at the video quality improvement that Pro-MPEG Forward Error Correction (FEC) has given; further equipment improvement is suggested.
