HDTV (high definition television) is digitally broadcast because digital TV requires less bandwidth. HDTV or High-Definition Television is a digital television system with greater resolution than analog or standard definition (SDTV) television systems. There were early attempts to develop analog HDTV and the most successful was Japan’s MUSE which was launched in the 1990s. It requires bandwidth greater than the traditional systems and was eventually turned off in 2007.
