TUAM 4.4 VIRTUAL EDITING OF MPEG-2 STREAMS

Disc based video recorders for consumers bring the possibility of virtual editing, that is, editing without making a copy of the underlying AN data.

Within the bridge sequence, some video is re-encoded and remultiplexed to ensure that the edited sequence can be played back seamlessly. The bridge sequence is stored on disc separately from the original sequences, which remain unchanged. BRIDGE-SEQUENCE EDITING
