Videos filming
The video-technology (lat). video = I sees, from videre "sees", includes the electronic procedures about the reception, transfer, treatment and rendering of moved pictures as well as ggf. the accompanying-sound (audio). The started appliances, like video-camera, VCRs and screen, belong to it furthermore. But also the purely digital processing of optical signals is considered one of the video-technology.
Video-storage-medium
As the magnetic tape, usually in a video cassette, in analogous form, first served storage-medium of the picture and sound-data, as Home system (VHS) in the video. Since 1996, increasingly digital record is put in, so in the digitally video (DP) - system with camcorders.
MPEG-2, MPEG-4, VCD, SVCD and DVD
Recently, magneto-optische procedures are increasingly applied together with digital compression, so in DVD-Camcordern. Since end of the 1990er years, the digital MPEG-Technologie places the standards on that occasion. U.a is based on her/its/their. the Video-CD, the DVD and this digitally video Broadcasting (DVB). She/it draws herself opposite DP through farther improved picture-quality from, more severe compatibility in the PC-area, as well as through easier and more extensive treatment-possibilities. The MPEG-4 format offers a stronger compression opposite MPEG-2 on the other hand, needs from higher processor-performance at record and rendering, however. Also, compression-artifacts can cause quality-losses with MPEG-4 sooner.
