HDTV (High Definition Television) is an innovative form of DTV for broadcasting TV programs. A HDTV receiver is a specially designed device to decode digital signals and enhance the quality of pictures and sounds of your home theater. The HDTV receivers are also known as HDTV set-top box or HDTV tuners.

Generally, the HDTV receivers collect and decode the signals and display the signals in 1080i and 480i or p format, where,
“i” means interlaced and “p” means progressive. The HDTV receiver can also be used to display videos from cable TV,
satellite TV, DVD players, or any other video source. The signals transmitted by the HDTV receivers will produce pictures
with high resolution and great clarity. Apart from transmitting high quality pictures, the HDTV receivers also broadcast
high quality surround sound.

When compared with other DTV receivers, the HDTV receivers come with many added advantages. Some HDTV receivers also come with access cards for security and digital video recorders. The HDTV receivers with digital video recorders can store programs up to 30 hours or 200 hours.
