Device for transmitting a digital picture signal.

摘要

By compressing HDTV pictures, they can be recorded on digital SDTV video recorders. Such recorders are widely used in professional studios. The invention relates to a device for formatting the compressed HDTV signal in such a way that the DC values of successive 8*8 picture blocks are processed by SDTV recorders as a smaller but recognizable SDTV sub-picture. Low-cost editing of HDTV programs with standard equipment (SDTV recorders and receivers) is possible with such a device, while the edited final result can be transmitted as a HDTV signal without any further processing operation. <IMAGE>
