HDTV (High Definition Television)
High Definition Television (HDTV) is a broadcast system that transmits pictures with more lines per frame, thus providing significantly higher resolution than traditional Standard Definition formats. HDTV provides powerful viewing experience with crystal clear picture quality, wide screen picture and digital surround sound. Aspect ratio of HDTV pictures is 16:9 as against 4:3 for SDTV (Standard Definition Television). HDTV can provide real difference in the programmes having fast and random moving objects such as sports events, live concerts, music videos etc. The use of HDTV in International sports events is increasing day by day and mega sports events are being covered in HDTV. The field of Cinema is also using HD format to store movies in digital form. HDTV is fast gaining popularity.
Doordarshan has taken up a pilot project of HDTV field production with a 4 camera HDTV van, EFP camcorders and post production facilities. Doordarshan has the plans to set up HDTV studios in Delhi & Mumbai, and field production as well as post production facilities for HDTV in the four metro cities of Delhi, Mumbai, Kolkata & Chennai. In addition, digital transmitters for transmission of HDTV programmes are planned to be set up at Delhi, Mumbai, Kolkata & Chennai. Also, an HDTV channel is proposed to be provided on “DD Direct Plus” free-to-air DTH service of Doordarshan. Implementation of above projects can be taken up after these are approved by the Government.
HDTV is best viewed on HDTV sets. HD ready plasma & LCD monitors are available in India. The existing SDTV sets can continue to receive HDTV signals by connecting through an external HD receiver box, which will improve the picture quality but not provide the full benefit of HDTV.
