My thought is that they have the logs, and they know who was where, and when. So they feed that into an animation/rendering engine and can construct 'scenes' from pretty much any angle or view point in the battle, they can take time to render detailed ship interiors for 'in the battle' views (complete with NPC characters). Do the whole military channel 'great tank battles' type coverage with order of battle before the engagement, key maneuvars, voice over commentary from notable Eve strategists etc. I could easily be done as inexpensively as 'clip shoes' like 'Dangerous Acts of Science' (Science channel) and have potentially a much wider appeal.
