The next VCRs from Philips could help people who fill their video tapes and
then cannot find anything they have recorded (WO 98/55942). The new device
records an index of thumbnail images in the first minute or two of tape. It does
this by running the tape through an analyser that searches for every scene
change or cut in a picture sequence. The cut point images are digitally
compressed to create a sequence of low-resolution pictures that are just clear
enough to give a clue to content. When you select an image, the video
fast-forwards the tape to that point.
