DVD Features 2-1 DVD is not a Digital Video Disc “DVD” is often considereed the abbreviation for Digital Video Disc, but as the unified standard for the next generation of high density optical fiber discs, the term “DVD” is not used in that way. It has been adopted as the name of the unified standard.

With its high quality imaging and high number of resolution lines, image outlines are sharp. Even in dark scenes, there is less noise and clearer perspective.
  • Page 9 DVD-Series DVD responds to wide sized screens From the beginning of its development, DVD was meant to be applicable for wide sizes. When zoom reproduced (expanding the mage in vertical and horizontal directions) on a wide screen monitor, the picture quality isn’t weakened. Instead, a beautiful and delicate image is reproduced.
  • Page 10 DVD-Series 1. Multi-Language Response (1) Sound Selection DVD Video contains a maximum of 8 sound streams. They flow together like traffic a digital signal road. Do not confuse this with “8 channels”. Including the original language, a maximum of 8 different languages can be recorded. Additionally, Dolby AC-3, 5.1ch can be included on all 8 streams.

  • Page 14 DVD-Series 4. The Expanding DVD World In converting music and data images into a unified file format, the border between TV and audio or computer is removed. As a result, DVD discs have many possible usages, including personal computer reproduction of DVD software and the playing of traditional audio CDs on the DVD player due to the compatibility of the hardware.
  • Page 15 DVD-Series 3-3 Moving Image Digital Compression Technology MPEG2 Enables Long Hour Reproduction Even though the recording capacity of DVD discs is 7 times more than a CD, if a TV image on NTSC is digitally transferred and recorded, even the DVD disc can record only 4 minutes. Research of the technology to record more information in a limited recording capacity (data compression) started in the 1960s.
  • Page 16 DVD-Series 2. Compression Method of Moving Pictures When you see a TV picture, you think of it as a sequentially moving picture, thanks to the afterimage effect that “fools” our eyes. But in reality, what you are watching is a series of still pictures that move sequentially and change at a steady rate.

To make coding easier, the quantitated value of macro blocks will be scanned in a zigzag pattern or alternately. 1 Ranlength Coding Because there are a multitude of zeros (unnecessary information) in quantitated value, it does not show all the zeros.

Also, it is difficult to judge how many 0s and 1s are being followed. Therefore, it is necessary to limit the length of the part without a pit on the track.

Because _ reflection rates, etc. differ on different discs it absorbs laser power, PD, an optical system changes with the passage of time, etc. of the need to decrease adjustment at the time of production The Following Adjustments are Actually Executed 1.
  • Page 26 DVD-Series 4. Focus Gain Adjustment Depending on the disc reflection rate, PD sensitivity difference, etc, FES output voltage changes against a certain amount of focus gap. For example, if FES becomes 1/2 of the same amount as the focus gap, servo output voltage reduces to half to revise it.

    DVD-Series 5. TRAYMECHA Control 5-1 Position of TRAYMECHA The TRAHMECHA position is detected by turning on 5 of SW. However, there are some cases when the position of the TRAYMECHA cannot be detected with SW input information only. In such a case, it is possible to specify the position from the condition of the SW input change when tray motor is rotated one direction or the other.
