An Experimental Digital VTR Capable of 12-Hour Recording

Digital VTR which records video-signals digitally is superior to general home-use VTRs with respect to SN ratio, resolution, and dubbing. However, digital VTR or DVTR has demerits, the biggest of which is a huge amount of tape consumption. In particular this demerit is fatal to home-use digital VTRs...

Description
Summary:Digital VTR which records video-signals digitally is superior to general home-use VTRs with respect to SN ratio, resolution, and dubbing. However, digital VTR or DVTR has demerits, the biggest of which is a huge amount of tape consumption. In particular this demerit is fatal to home-use digital VTRs. Therefore, it is very important to establish techniques which make it possible to record digital video signals as long as possible without excessive tape consumption.
