| when using this kind of disc. |
Interlace | It is a process in which the picture is split into two fields by sending all the odd |
| numbered lines to field one and all the even numbered lines to field two. This |
| allows a whole picture to be produced in two very fast scans. |
JPEG | Joint Photografic Expert Group. File format for pictures with high compression |
| degree. |
kHz | Kilohertz. kHz is the indication for the height of the scanning rate with which an |
| analogue signal (PCM) is interrogated for the following analogue/digital transfor- |
| mation. |
Macrovision | Analogue copy protection which scrambles the video signal when used with |
| VHS recorders. Also has an effect on some projectors and monitors. |
MP3 | A compressed audio format. MP3 files recorded on |
