Anleitung Zusammenfassung
In order to view DTV programming, the STB must be connected to the TV component video inputs (Y, PB, Pr) and audio inputs and in DTV mode. A DTV signal must be available in your area and the DTV-STB must be tuned to the proper channel. Progressive Scan Progressive scan de-interlaces the incoming signal and progressively scans the image. This allows you to sit very close to the TV and not see the thin black horizontal scan lines (Venetian blind effect) associated with an interlaced picture. Frequently Asked Questions About Digital TV Frequently Asked Questions About Digital TV What is digital TV (DTV)? In April 1997, the FCC (Federal Communications Commission) announced that by 2006, all television broadcasting will be digital. Digital TV broadcasting delivers crystal-clear pictures, approaching the quality of 35mm movies and CD (compact disc) sound. Digital broadcasts include both High Definition Television (HDTV) and Standard Definition Television (SDTV). Broadcasters may choose their own broadcast formats. HDTV (High Definition Television) One form of digital broadcasting is HDTV, which provides the highest resolution picture. Besides incredible picture, the sound is available in the 5.1 channel surround sound. SDTV (Standard Definition Television) Another form of digital broadcasting is SDTV, which provides lower resolution, but still presents a very sharp, clear picture. Lower resolution allows broadcasters to transmit more than one program per channel. When will TV stations start broadcasting digital signals? Television stations are required to continue broadcasting regular TV signals along side the digital signals until 2006. Cable TV and satellite TV are not affected by this FCC ruling. All stations are required to become digital by 2006. This will be an evolutionary process. According to the FCC, digital broadcasting must be available in the top ten markets, covering 30% of households by May 1999. By the end of 1999, digital broadcasting must be available in the top 30 markets, covering 50% of households. Will I be able to adapt my current TV to receive digital broadcasts? Manufacturers wilt offer a digital TV set-top box (DTV-STB) which will allow current televisions to display digitally broadcast programs. The picture and sound quality will be about the same as small dish digital satellite systems today. Conventional televisions (non-digital televisions) will not be able to display the HDTV resolution quality or sound. What digital formats will broadcasters use? There are presently four DTV formats: 1080i (interlaced), 720p (progressive), 480i and 480p. The higher numbers indicate a higher resolution picture. In an interlaced picture, the odd numbered lines (picture information) are scanned first creating field 1 and then the even numbered lines are scanned, creating field 2. The two fields are then interlaced to provide the entire image (one frame). This process happens in 1/30th of a second and is invisible to the human eye. In progressive scanning, all lines in the entire frame are scanned sequentially in 1 /60th of a second. Broadcasters may choose to transmit different levels of resolution throughout the day, broadcasting day programs in SDTV and night sports and movies in HDTV.
