This paper describes the recent trends of High-Definition TV (HDTV) transmission technologies. The HDTV signal bandwidth is extremehy wide and the source bit rate is about 1.2 Gb/s (studio quality). or 600 Mb/s (distribution quality). For analog transmission, bandwidth compression methods based on various sub-samplings have been studied. For digital transmission, bit rate reduction coding methods have been studied. Experiments of HDTV transmission have been carried out using satellite circuits and optical fiber Lines.
