<p>A digital transmission and/or recording system for component-coded colour-TV signals. At present, no professional video recorders are available which can record progressive 16:9-format 625-line TV images. Digital studio video recorders operating by the D1 process can only record the YUV components of interlaced 4:3-format 625-line images. By means of vertical sub-scanning of the UV-components and subsequent block companding using special encoding techniques within 8-byte blocks (40), the necessary memory capacity is made available for recording progressive 16:9-format 625-line TV images. The invention is of particular application to the digital recording of progressive 16:9-format 625-line TV signals using PCM video recorders.</p> |
